Starting with virtualbox 6.1.28 (tested as well on 6.1.30, 32, 34 so far) there is no audio input after rebooting a Windows 10 guest VM. The audio interface is present, but only silence as audio ""in"" after a reboot (audio was present at first boot). Everything was working well with virtualbox 6.1.26 or before.

The problem is easily reproduced at first try on any machine I have (tested several hardware, different sound cards, different CPU architecture amd or intel, different host os : debian 11 or windows). The problem always apear after the first (and any subsequent) reboot of the machine (either user induced, or due to and update or a VM crash).  

Also tested several Windows 10 versions (LTSC ; entreprise ; home), all have the same problem.
Depending on the host, I have tested several drivers (Alsa and PulseAudio on Linux and ""Windows Direct Sound"" on Windows).
The problem is the same if the Guest Additions are installed or Not (therefore, not a problem with the GA).

Please see attached some logs taken with extended audio logs using options ""VBOX_RELEASE_LOG=drv_host_audio.e.l.l2.l3.f+drv_audio.e.l.l2.l3.f+audio_mixer.e.l.l2.l3.f+dev_hda_codec.e.l.l2.l3.f+dev_hda.e.l.l2.l3.f+dev_ac97.e.l.l2.l3.f"" :

20628	Windows: Guest Additions installation might fail due to missing certificate	all	VirtualBox 6.1.28	2021-10-24T01:27:33Z	2022-07-01T18:35:31Z	2022-07-01T18:35:31Z	"When I tried to install the Guest Additions on a Windows Server 2022 guest that couldn’t reach the Internet, the installation failed with the following messages in the ”Oracle VM VirtualBox Guest Additions 6.1.28 Setup” window:

{{{

ERROR: Adding driver to the driver store failed!!
Execution returned exit code:  2
Error excuting """"C:\Program Files\Oracle\VirtualBox Guest Additions\VBoxDrvInst.exe...
}}}

I found that the Oracle certificate that had been used to sign the Guest Additions device drivers, security catalog files, and so on, has a certification path for which the only trusted root certificate, in a new installation of Windows Server 2022, is a DigiCert Assured ID Root CA certificate signed by Microsoft. That root certificate expired on April 15, 2021, as described in this Microsoft document:

https://docs.microsoft.com/en-us/windows-hardware/drivers/install/deprecation-of-software-publisher-certificates-and-commercial-release-certificates

If the guest had been able to reach the Internet, I think the Automatic Root Certificates Update feature of Windows would have installed a better root certificate automatically. This guest had to remain offline, so I worked around the problem by installing an unexpired version of the DigiCert CA certificate into the Local Machine/Trusted Root Certification Authorities store, as I described in the forum:

https://forums.virtualbox.org/viewtopic.php?f=1&t=104204

The certificate I installed is:

https://cacerts.digicert.com/DigiCertAssuredIDRootCA.crt

After this, when I ran the Guest Additions installation again, it was successful.

For reference, I installed Windows Server 2022 from the following image, published on visualstudio.com: en-us_windows_server_version_2022_updated_october_2021_x64_dvd_b6e25591.iso

If it’s not feasible to fix this problem by signing the Guest Additions using a certificate for which a trusted, unexpired root certificate exists by default in all Windows installations, then I’d suggest including a copy of the DigiCert certificate with the Guest Additions and prompting the user to install it, if needed.

This shouldn’t be done silently, by the way: I’ve used VirtualBox to investigate other certificate-related problems like this one, and having any non-default certificate appear on its own would be unfortunate."	w16r
19839	Default Windows Unattend Template Requires Product Key	all	VirtualBox 6.1.10	2020-08-27T18:33:47Z	2021-02-01T22:31:55Z	2021-02-01T22:31:55Z	"'''Problem''':

The default Windows answer file template (i.e., ""<vbox_install_dir>\UnattendedTemplates\win_nt6_unattended.xml"") requires a product key. Failure to provide the key results in Windows throwing the following error and aborting install, even if ""<AcceptEula>true</AcceptEula>"" is provided.

{{{
Windows cannot find the Microsoft Software License Terms. Make sure the installation sources are valid and restart the installation.
}}}

[[BR]]

'''Impact''':

This prevents users from performing unattended installs of Trial / Evaluation copies of Windows without additional (and non-intuitive) configuration. This is very difficult to troubleshoot as the Windows error message refers to licensing rather than product key / activation issues.

[[BR]]

'''Workaround''':

Creating a modified copy of the template, containing: 

{{{
<UserData>
    <AcceptEula>true</AcceptEula>
</UserData>
}}}

rather than the default:

{{{
<UserData>
    <ProductKey>
        <Key>@@VBOX_INSERT_PRODUCT_KEY_ELEMENT@@</Key>
        <WillShowUI>OnError</WillShowUI>
    </ProductKey>
    <AcceptEula>true</AcceptEula>
</UserData>
}}}


and referencing this during using --script-template="""" solves the problem.

Example: [[BR]][[BR]]
VBoxManage unattended install Server2019Template --user=Administrator --password=password --country=US --time-zone=MST --hostname=Server2019Template --image-index=2 --install-additions --start-vm=gui --iso=<ISO_PATH> --script-template=""<path_to_modified_template>\win_nt6_unattended.xml""

[[BR]]

'''Recommended Solution''':

Implement template conditional similar to ""@@VBOX_COND_IS_USER_LOGIN_ADMINISTRATOR@@"", that prevents the ""<ProductKey>"" block from appearing in the final XML answer file if no key is specified on the command-line for ""VBoxManage unattended install"".

If this cannot be fixed quickly, please at least update the documentation to mention this requirement and workaround."	breakid

However, it seems that the Windows host will sometimes delete the MediaRegistry/HardDisks section in the .vbox file on opening if it has a version of ""1.15-macosx"". The same file is untouched if it has a version of ""1.15-windows"".

All of the changes that it does:
 - Removes MediaRegistry/HardDisks section
 - Sets Memory RAMSize from 8192 to 128
 - Removes Hardware/Display
 - Removes Hardware/VideoCapture
 - Removes Hardware/BIOS
 - Removes child elements and all attributes except type=""Am79C973"" from Network/Adapter slot=""0""
 - Removes Hardware/Clipboard
 - Removes Hardware/DragAndDrop
 - Removes StorageControllers"	Shonn
17273	5.1.24 regression: Windows 10 guest microphone stops working after high host CPU load	all	VirtualBox 5.1.24	2017-11-14T16:39:12Z	2018-03-21T07:02:43Z	2018-03-21T07:02:43Z	"In VirtualBox 5.1.24, when the host CPU usage gets very high (i.e., close to 100% on all cores), then the microphone in a Windows 10 guest stops receiving sound. Note that it continues to receive no sound even after the high host CPU usage has stopped. The microphone works just fine ''before'' the high CPU load in the host. This issue does not occur in VirtualBox 5.1.22, and therefore appears to be a regression (the changelog mentions audio-related changes for better Windows 10 support, so it would make sense).

This issue occurs with both a Linux host (Ubuntu xenial) and a Windows 10 host. The guest was Windows 10 in both cases.

Steps to reproduce this issue:
1. Create an up-to-date Windows 10 guest using Intel HDA as the sound device. The host can be either Windows or Linux since the issue occurs with both. The host should be using VirtualBox 5.1.24.
2. In the guest, right-click the audio icon next to the clock and choose Recording Devices. This shows a volume meter for the microphone. Check to see that the microphone works before proceeding. Do not switch to another tab in the window during the test since that seems to reinitialize the microphone ""connection.""
3. In the host, cause a high CPU load. I did this by running 5 instances of a simple Python script that calculates Fibonacci numbers (attached).
4. After about 10-20 seconds, the volume meter either doesn't respond anymore or stays stuck on a particular volume. Killing/waiting for the Python scripts to terminate doesn't cause the volume meter to start working again. Only switching to another tab and back seems to reinitialize the microphone and fixes the issue temporarily. In 5.1.22, the volume meter never freezes.

It is also possible to test using the Voice Recorder, there I noticed that only a static noise is received after several seconds of high host CPU usage. The easiest way to reproduce, however, is to use the Recording Devices panel.

I have tested using VirtualBox 5.2.0 as well, and the same issue exists there. However, 5.1.24 is the earliest version that has this issue."	ocecaco

when adding a virtual hard disk drive via an USB storage controller, at least Windows will treat the connected drive as an ""USB Mass Storage"" device but in **fixed**-layout.

Also, when checking the ""Hot-plug""-feature of the hard disk, the Drive will be treated as fixed-disk.

My expectation was, that when checking ""Hot-Plug"" it would be a removable one.

Would it be possible to optionally set the ""Removable-Bit"" in the USB-Drive's properties, so that it is marked as ""removeable"" ?

Would be great, as some applications check drives for this.

Thanks for the work you put into OVB, I think it is great!

I have run into a problem with the latest releases that I would like your help with. I have been running OVB for about a year or so and have not had a problem with this software until recently. HP Solution Center is an app that is installed with the HP all-in-one printer driver/software and I use it to launch the scanner component. 

It works fine with OVB releases 4.3.30 and 4.3.32, but it causes an issue in 4.3.34 and 5.0.10. I have not tested earlier releases of 5.0.x. 

I have 64-bit Win 7 guest running on Ubuntu 14.04 LTS.
I have a Photosmart C7280 connected via USB 2 EHCI controller. I have also reproduced the issue when setting up the printer as a network device (bridged Intel PRO/1000 MT Desktop (82540EM)), rather than a USB device.

To download the software, go to http://support.hp.com/us-en/drivers/ and enter the model of ""photosmart c7280"", change the selected OS to MS Win 7 (if not already selected), and download PS_AIO_02_Net_Full_Win_WW_130_140.exe (released 2009-10-20). 

I believe during installation you can skip the printer setup. However, I'm not sure if the issue is reproducible without a printer/scanner being set up. I can do more research and update this ticket. 

Once the installation has completed (and after rebooting), the next and final step is to launch HP Solution Center. 

I set the priority to major without knowing the cause or the full effect of this issue. My guess is that it could be affecting other printer software, and possibly more. 

Thanks for your help.

12605	Slow accesses for XP guest shared folders	all	VirtualBox 4.2.20	2014-01-13T10:42:10Z	2014-11-27T14:30:31Z	2014-11-27T14:30:31Z	"This problem appears to have a long history (see ""Archaeology"" below).  

'''The symptom:''' XP guest accesses to shared folders at !\\vboxsvr are intermittently stalled, apparently for name resolution.  This happens on both Win7 and CentOS hosts.

'''To replicate:'''
* Fresh install of XP SP3 guest.
* Install Guest Additions
* Add a shared folder - a temp directory with a folder tree (e.g. directories a, b, and c, each with subdirectories 1, 2, and 3) will be convenient.
* In Start -> Run, open a !\\vboxsvr explorer window.  Initial access will stall for 5-10 seconds, after which response is speedy (browse down the folder tree to a/1, b/2, c/3, etc.)
* Doing something else (open a My Computer window) and returning to !\\vboxsvr explorer window will usually result in the next action (e.g. browsing back to directory a/1) being delayed.

'''Affected systems:'''
* VBox 4.1.18 Host: Win 7 64bit Guest: WinXP SP3
* VBox 4.2.20 Host: CentOS 6 64bit Guest: WinXP SP3

'''Unaffected systems:'''
* VBox 4.1.18 Host: Win 7 64bit Guest: Win2K
* VBox 4.2.20 Host: CentOS 6 64bit Guest: Win2K

'''Observations:'''

I have tried each of the following workarounds (both separately and in various combinations).
* Added 255.255.255.255 vboxsvr #PRE to lmhosts; rebooted; '''problem still occurs'''
* Added 127.0.0.1 vboxsvr to hosts; rebooted; '''problem still occurs'''
* Turned off NetBIOS and Windows file sharing (Network Connection -> Properties -> uncheck Client, File Sharing) ; '''problem resolves''' (no stalls, but no Samba access either, of course).
* Turned off all networking (Network Connection -> disable connection) ; '''problem resolves'''
* Disconnected (virtual) network cable via VBox network adapter menu ; '''problem resolves'''
* ipconfig /all shows Node Type is ""Unknown"".  Forced to ""Broadcast"" to match Win2K configuration by setting HLM\SYSTEM\CurrentControlSet\Services\NetBT\Parameters\NodeType = 1.  '''Problem still occurs'''.
* Verified HLM\SYSTEM\CurrentControlSet\Control\NetworkProvider\Order lists VBoxSF.  Although VBoxSF is listed first, netbios broadcasts for vboxsvr still go out when lmhosts is not ""patched"".  Broadcasts do not occur if lmhosts is patched, but access stalls still occur.  Note that Win2K apparently caches the name lookup - Win2K will broadcast on initial access attempt, but never again.  I think XP is retrying the name lookups, leading to the periodic delays.
* My local network does not have any name servers (DNS/WINS).

'''Archaeology:'''

Most of the tickets below have been closed as duplicates of ticket 1728, and relate to speed of file transfers.  Arguably *this* ticket is probably a duplicate of 1728.  I figured I'd try a new ticket since it's been 2 years since 1728 showed any activity, and I have a simpler reproduction method - delays can be observed merely navigating the shared folder's directory tree.

I believe the first two files can simply be deleted as they are merely cached copies. The third, msd3d9.dll, was not present on the Windows media I was using, and I suspect it can be deleted as well. 

The documentation should be updated to include instructions about deleting these files manually. Alternately, the installer could delete these files itself."	Ryan Steele
13249	A requested new spin on Ticket#11176 Mouse integration and snap to default button in a guest OS	all	VirtualBox 4.3.14	2014-07-29T17:00:21Z	2014-07-29T17:00:21Z	2014-07-29T17:00:21Z	"Please consider adding an option that could be enabled on trusted Windows guests that would allow guest-initiated mouse pointer movements to occur.

Many professionals use the ""Snap to default button"" on Windows hosts, and would like this option available on Windows guests.

If an optional checkbox is addded to VirtualBox Manager:
Settings \ General \ Advanced \ [X] Allow Mouse Pointer Snap
It would help to improve VirtualBox popularity for Windows Guests.

And by making this feature optional, it will not interfere with justifications for not allowing this level of control for all Guests by default.

Thank you for considering.

Original ticket#11176 text follows:

Mouse integration is a great feature, but misses one piece: guest OS can not control position of mouse pointer. This can be easily verified in the Windows XP guest OS. Go to the Control Panel/Mouse, select 'Pointer Parameters' tab and check the 'Snap to default button' checkbox. After this, with mouse integration disabled mouse cursor will jump to the default dialog button (eg, the OK button). It will not however, with mouse integration enabled. This will also cause problems with programs which move mouse cursor programmatically and expect it to actually move. 

Thank you again for considering.

21448	VirtualBox 7 VM Freezes or UI glitches	Linux	VirtualBox-7.0.6	2023-01-30T15:54:14Z	2023-02-14T08:39:15Z	2023-02-14T08:39:15Z	"Using VirtualBox VM 7.0.6 (guest additions installed) with an Ubuntu 22.04 LTS host and Win 11 guest, with an nvidia RTX 3080 Ti (and attaching log).

If I use the above combination I get frequent VM freezes (even if I leave it for hours).  This happens regularly especially  when I launch a browser (both MS edge and firefox exhibited this behaviour). The only way to recover is with a ""power off"" of the VM.

I have read in the forums (second post here: https://forums.virtualbox.org/viewtopic.php?f=2&t=107371) that this happens with VB7 and the solution for it is to enable 3D acceleration in the settings. I do that and the VM stops freezing BUT ...

The UI is almost unusable as it is broken in multiple ways (even when switching transparency off): broken borders, broken backgrounds, flickering, fonts looks rough, buttons disappear, etc etc etc.  For example when I launch MS Office, I get an empty (white) panel and nothing else. This is certainly related to 3D acceleration as when I set a regedit key (DisableHardwareAcceleration to 1) to disable 3D hardware acc. for office 365, this starts working normally.  But the rest of the OS still suffers from the visual glitches.

Let me know if you require any more info.

Machine is a laptop with an Intel Core i7-10510U CPU and Intel integrated graphics.

I am trying to use a Windows 11 guest.

If I set the paravirtualization interface to ""default"" or Hyper-V (which I guess is the default when windows 11 guest type is selected), then the Windows 11 guest hangs quite frequently. In fact, trying to start word is enough to systematically hang the guest OS. If I set the paravirtualization interface to KVM (which I guess is something that Win11 cannot talk to), then I have no hangs.

I do not know if this is relevant, but I have the latest Virtio drivers for paravirtualized SCSI and network interface installed in Windows.

Bug: Copying URL from guest to host causes the VM to crash

Bug Description:
When Shared Clipboard is enabled, it's possible to copy text from guest to host and vice versa, however when ""particular"" things like URL and other particularly formatted texts are copied (like from Chrome etc) those fail to be converted properly and therefore cannot be pasted to the host. On top of that, this might lead the guest to crash, which of course is bad.

To highlight the relevant portion of the logs, I'd say that this should give a pretty good insight:

Other split_lock traces have different detailed call stacks, but the reproducer below causes a split_lock 100% of the time.

Steps to reproduce:

Hardware: XPS 9310, Ubuntu 20.04.1 w/ HWE kernel host, Virtualbox 6.1.32

1. Install Windows 10 x64 20H2 in virtualbox (all default options).

2. Download the visual studio tools installer in guest: https://aka.ms/vs/15/release/vs_buildtools.exe

3. Attempt installation:
vs_buildtools.exe --wait --norestart --nocache modify --installPath ""%ProgramFiles%\Microsoft Visual Studio\2017\BuildTools"" --add Microsoft.VisualStudio.Workload.MSBuildTools --add Microsoft.VisualStudio.Workload.VCTools --lang en-US

Just upgraded from 6.1 to 7.0 and tried to use a Windows 11 guest known to work well with 6.1.

- Initially the Windows 11 guest was not even starting;
- Disabling 3D acceleration made it start;
- Updating the Guest Additions allowed to re-enable 3D acceleration without boot failures however, there are all sort of visual artifacts and prominently, characters become unreadable.

I suspect this may be triggered by my specific graphics card or graphics stack."	sercallegar

I'm trying to use my Windows VM to compile the Windows version, but it crashes as it tries to launch even the default program.

I initially thought it was a Flutter problem and opened a ticket here:
https://github.com/flutter/flutter/issues/99101

To reproduce, you need to install Flutter:
https://docs.flutter.dev/get-started/install/windows

I simply created a template program using
flutter create testwin
cd testwin
flutter run

This is the error message I get when I try to debug with Visual Studio:
Unhandled exception at 0x00007FFC63716A3D (VBoxDispD3D.dll) in testwin.exe: 0xC0000094: Integer division by zero.

kernel 5.4.0-132
Wayland, Gnome 3.36.8

Procedure:
Start guest VM; boot; login
From VM window menu -> Devices -> Insert Guest Additions CD image...
Start Guest additions installer from Windows Explorer
Install runs through until the graphics driver is installed.
Window resizes shortly to VGA (probably the 'uninstall' of the old driver) then goes back to previous resolution (probably when the new driver is enabled).
This is the moment when the VM crashes.
Reproducible.
This error is new in 7.0.4. It was not there in 7.0.2.
The Windows VM can be restarted normally after the abort and the guest additions appear to be installed, including the graphics driver. Vbox Task Bar App reports v7.0.4 installed.

Guest: Windows 10 64-bit with latest GAs installed

FWIW, these are the same symptoms reported in [https://www.virtualbox.org/ticket/16593] ; that bug says it was fixed in 5.1.22

I'll attach before & after screen shots and VBox.log files.

STEPS TO REPRODUCE:
1.  Boot Win-10 VM, expand the VM window to a large size.
2.  Click the ""X"" window-manager icon to close the VM window
3.  Check ""Save state"", click OK
(VBox.log.1 was from the above)
4. In VB gui, click ""Start"" to restore the VM

Initially an image of the large VM window appears with the ""restoring..."" progress meter.
   
Then the VM window shrinks to a small size


(VBox.log is from step 4.)

All the 3d CAD legacy programs I am trying to work, either default to software openGL or display nothing.

I tried running the openGL diagnostic program called glview from here https://realtech-vr.com/home/glview, it also displays the same behaviour (does not show anything but garbage).

All the legacy programs run fine on the same Windows 7 natively (non virtualised)

Any suggestions for a fix or a meaningful work around? Tnx.

20832	Fedora-35 HOST + Windows 10/11 GUEST: Keyboard entries and Touchpad Taps stop responging, after ~10m	Linux	VirtualBox 6.1.32	2022-02-17T15:54:38Z	2022-10-10T12:08:30Z	2022-10-10T12:08:30Z	"Dear Friends:

I have a bug that I've been facing for approaching 2-years (19-months, actually). No matter what I do, the bug remains. Let me explain.

The bug, which I describe further below, first appeared in '''August''' of '''2020''' on '''Fedora-32 64-bit''', which is the '''HOST''' O/S. Back then, I had hoped that the bug would be confined to a particular '''Fedora Kernel''' and waited for the next one; but as I upgraded Fedora-32 Kernels, the bug persisted.

Then, I eventually upgraded to '''Fedora-33''' (again, the '''HOST'''), and the bug persisted through that Fedora version and through all of its Kernels, as well. The same occurred with '''Fedora-34'''.

For '''Fedora-35''', I decided to reinstall everything from scratch: I reinstalled '''Fedora-35''' ('''HOST''') from scratch; as well as reinstalled '''Windows-10''' ('''GUEST'''). Without customizing much, except to apply the '''Extension Pack''' and '''Guest Additions''', I launched a Windows-10 VM (with everything fresth). The bug immediately surfaced. It always takes about ~5 to 10 minutes to occur, by the way.

Now, all of this was on a '''Lenovo''' '''Y700-17isk''' Laptop.

So, I decided to do the same procedure on an '''ASUS G750 Rogue''' Laptop: I installed '''Fedora-35''' ('''HOST''') from scratch; as well as installed '''Windows-10''' ('''GUEST''') from scratch. Without customizing much, except to apply the '''Extension Pack''' and '''Guest Additions''', I launched a Windows-10 VM (with everything fresh). The bug immediately surfaced. 

No matter what I do, I cannot get rid of this bug. I think that circa '''August 2020''', either '''Fedora''' and/or '''VirtualBox''' changed something that is causing this long-running bug.

'''THE PROBLEM''':

-- I first reported this problem on '''August 2020''' ('''Lenovo Y700-17isk''' laptop) [https://forums.virtualbox.org/viewtopic.php?f=7&t=99328 here]

-- Then, I reported this problam again yesterday, '''February 2022''' ('''ASUS G750 Rogue''') [https://forums.virtualbox.org/viewtopic.php?f=7&t=105295 here]


Here is a paste of yesterdays description for your convenience:


{{{
VirtualBox Version..................: 6.1.32_rpmfusion
HOST O/S............................: Fedora-35
HOST Kernel.........................: 5.14.10-300.fc35.x86_64
GUEST O/S (with latest updates......: Windows-11 (happens with Windows-10, as well)

}}}


What happens is this: VirtualBox is working perfectly (Network, Audio, Shared Drive, Cut & Paste, Keyboard & Mouse Capture, Mapped USB Devices, etc); but then suddenly, after, say, 5 to 10 minutes, the Keyboard stops responding to Keystrokes, and the Touchpad stops responding to Taps. The only thing that responds is moving the mouse-cursor around by swiping around the Touchpad, but that's it. This happens whether or not the GUEST (Windows 10 / 11) is in Fullscreen mode or Window mode. Except for being able to move the mouse-cursor around, Keystrokes and Touchpad Taps stop working inside the GUEST window, or around it on the HOST. The only option I have to to crash the Laptop by holding the power-button down. Actually, I did try to SSH into the HOST from another server, and while it does initiate the SSH connection, it never can never actually log in. So the HOST is still quote/unquote kind of running, but in a hobbled state.

I should also mention that this issue arises even with more basics setups: USB disabled; Audio disabled; Network with LAN or Bridged; etc.

Please help me. I think this is a real bug. It persists no matter what I do. For the better part of two-years, I haven't been able to use VirtualBox.

I can upload or add more information. Just let me know what you need.

From time to time I experience different kinds of freezes. Sometimes, when I am in the VM I can contiue to work in the VM, but can't select another window from the host. Sometimes, when I am outside of the VM I can continue to work in all windows of the host, but can't switch back to the guest. In all cases so far I was able to switch to the console (Ctrl-Alt-F2) and back to the GUI. The mouse continues to work.

Often the system went back to normal after waiting for a couple of seconds. But some times, even waiting for 10 minutes, does not solve the problem and the poweroff via the CLI from the console helps: ""VBoxManage controlvm poweroff"".

I had this problem also seldomly on KUbuntu 18.04. It was so rare that I did not bother. Now it is happening more often and I already tried to find a solution via Google.

By now I am quite certain that it is caused by copy-and-paste in the Windows VM and keeping things selected. Especially when working with Excel. This forum post seems to describe the same issue: https://forums.virtualbox.org/viewtopic.php?t=99685

At the time I thought it might be related to using shared folders, but by now I am quite certain that copy and pasting from Windows to Linux causes the problem.

Mouse click stops working on host/guest due to window focusOutEvent problem in Qt GUI

Postby Cryptkeeper » 7. May 2021, 17:37
Hi,

for more than two years now (so probably since VB version 6.0 or so) from time to time I am affected by a very anoying bug. Then mouse clicks stops working on the host and the guest as well. I can still move the mouse pointer but clicks are not recognized anymore. The only solution then is to shut down *all* running guest instances. Then the mouse clicks starts working again.

I am sure it is not a drag and drop problem like in https://www.virtualbox.org/ticket/14743

There will be no entry in the logs, when the bug occurs. It happend very randomly to me but after a while with a screen record I figured out the following steps to reliable reproduce the bug:

1) Click on the taskbar to restore VM window from minimized state
2) Press down the mouse button on the taskbar and keep it pressed
3) Release the mouse button and immediatly press it again
4) Now no further clicks are registered until VM is shut down

(I agree that this looks like a very special and rare circumstance - however I think that this bug is a race condition and as I often switch between different windows with the taskbar I'm hit by it very often.)

Here is a screencast of the bug as GIF: https://s3.gifyu.com/images/vbox-bug.gif

When the bug occurs *xprop* on the hosts exits with the error ""xprop: error: Can't grab the mouse"" - on the guest it just hangs as no click is registered. Also the bug only occurs with the Qt front end of VirtualBox - with the SDL front end I couldn't reproduce the error.

From the steps I assume that the bug is kind of a race condition on the minimize respectively focus out / focus in event of the window. So I tried to build VirtualBox from source and try to trace the bug. And indeed I figured out, that the bug does not occure if I comment out the following 3 lines in the file src/VBox/Frontends/VirtualBox/src/runtime/UIMachineView.cpp.

Code: Select all   Expand view
    void UIMachineView::focusOutEvent(QFocusEvent *pEvent)
    {
        /* If native event filter exists: */
        if (m_pNativeEventFilter)
        {
            /* Uninstall/destroy existing native event filter: */
               
            //qApp->removeNativeEventFilter(m_pNativeEventFilter);
            //delete m_pNativeEventFilter;
            //m_pNativeEventFilter = 0;
        }

        /* Call to base-class: */
        QAbstractScrollArea::focusOutEvent(pEvent);
    }



I tried to dig deeper but I'm kind of stuck. Because I don't know what this native event filter is used for and why it is destroyed on focus out event.

Can anyone help me to debug this further?

Thanks a lot!"	Seann

When i am in Virtualbox Manager and want to edit a setting of a VM that is NOT running, i get a warning that the VM is running and not all settings are stored or changed.. every time that script is called. The exact warning is in Dutch, but from the forum is got this in English:

'''""The virtual machine you are changing has been started. Only certain settings can be changed while a machine is running. All other changes will be lost if you close this window now""'''

The line in the bash script is:
'''""vboxmanage showvminfo ""W7_64"" | grep -c ""running (since"" ""'''

So calling ""vboxmanage showvminfo"" creates a warning that the VM is running when you try to edit guest settings.

To create this situation, open vbox manager, click on usb settings an leave that open, then go to the terminal and start ""vbmanage showvminfo"". The warning pops up that the VM is running.

17215	Guest additions command line updating fails (Linux host, Windows guest) => Obsolete	Linux	VirtualBox 5.2.0	2017-10-27T09:13:59Z	2022-04-19T14:54:50Z	2022-04-19T14:54:50Z	"I have a Linux host (Ubuntu 16.04, 64 bits) and a Windows guest (Windows 7 professional, 64 bits). I try to update the guest additions using the command line.

So I issue the command (from the Linux host, with the VM guest powered on):
{{{
VBoxManage guestcontrol ""win7""  updateadditions --source /usr/share/virtualbox/VBoxGuestAdditions.iso --verbose
}}}
The command fails and I get the following output:
{{{

I tried with Virtualbox 5.1.30 and 5.2.0 and I get the same result.

Manually updating the guest additions (withon the guest) works as expected.

And I was also able to start a program within the guest, using commands like:
{{{

Said this, i have an scarlet4i4 focusrite 3gen audio interface, after several tries and problems i get it to setup and make it work.... but i have no output sound in my speakers.

Seems that the setup is correct and in windows works, but some kind the sound gets lost from output of the guest

I tried to connect JMicron Icy Box IB-G1826MF-C31 inside with a Crucial P5 Plus 500GB nvme m.2 ssd through USB to the guest system but I get only notification to the device connection but no drive assigned to it. If I add the drive letter manually in the disk manager of the guest system then I can browse the files on it, but only read only. The host system is a Fedora 35, the guest system which I tried was Windows 10 and Windows 7 fully updated. Any other USB devices are working, for ex. Kingston 128GB stick, or webcam, etc. If I connect this USB kit to the host system I can read and write files and folders, its the same when I use it on windows based host system. I need to use it like an usb device because the Rekordbox software (shared folders way not a solution).

Note that the version of the extpack (6.0.0 or 6.0.2) installed (both in VirtualBox and in the guest OS) does not seem to matter: it's broken at VirtualBox level itself, apparently.

This is a showstopper bug: pretty please, fix it quickly !

After powering on a windows VM the VM stops reacting to mouse clicks or keyboard input. With Guest Additions installed the mouse pointer still moves. The VirtualBox app window won't refresh. I have to destroy the VM window to resume normal operation. When I start the Windows VM in safe mode mouse and keyboard work fine. Another observation is that the Remote Display is affected too (RDP client connects, changes size to VM's resolution, but black window) and works only when VM is started in safe mode. A downgrade of VirtualBox 6.1.22 resolves all issues."	madires

The problem arises running a CAD application within the guest and rendering a 3D-Model.
The model appears top down. It is not possible to rotate it to head up. Also, some textures of faces are not displayed (these structures are displayed like wireframe - front faces missing).
When I use a Mesa (Software) renderer client by the application, opengl rendering works correct, but much slower - as expected.

This was first reported at https://bugzilla.opensuse.org/show_bug.cgi?id=1192338 where the reporter noted that he could not attach an iPhone to iTunes through his Windows 10 VM on an openSUSE Leap 15.3 host. He also notes that when the VM is closed, there is no power on the USB port until he reboots.

I further tested using an RTL8188EUS Wifi dongle passed through to a Windows 7 or 10 guest from an openSUSE Tumbleweed host. In this case, the Windows software creates a network device, but is unable to complete setting it up. This operation worked with 6.1.26.

If I switch off the clipboard exchange - everything will be OK for many days long, but as soon as I switch it on - I get that problems.

I have a laptop with a 4K display. KDE / Plasma 5 are not yet suited to the resolution. To help with icon size I selected System Settings => Display and Monitor => Scaled Display (button) and set the scale to 2.0.

This doubled all my icons nicely, but within the Windows 10 VM, the graphics were scaled to half resolution on both axes, but were not scaled back up to fill the screen. Mouse clicking was difficult because they were based on the full size of the window but the graphics were 1/2 size.

This is a small issue as I just turned of the Plasma feature to fix VirtualBox. And since it limits display resolution, it's probably not a good fix for the small icons.

Similar segfaults have been observed by others in the forums. As noted by some, the Virtualbox logs do not indicate a problem at the time of the crash.
Shared Clipboard is DISABLED for the guests.  I do not make use of this feature and so turn it off for my guest machines.

Host: Fedora 32 Linux running kernel 5.11
Virtualbox installation via virtualbox.org site: Fedora repo and manually downloaded extension pack.

I've noticed the problem since upgrading from Virtualbox 5.2 to Virtualbox 6.x as part of an upgrade from Fedora 30 to Fedora 32 several months ago.

The problem has persisted through a recent upgrade to Virtualbox 6.20.

If I do not log into the Guest after booting the guest, but shut it down from the Guest login screen, the guest shuts down without crashing.  I'm assuming that this is related to engaging some part of the Guest additions services after logging into the guest.  Again, Shared Clipboard has been turned off in the guest's options within the Virtualbox control GUI.

As I understand it, the shared clipboard will run services on both the host and the guest to manage the data exchange.  It appears that something may trigger a poling of the clipboard from the host side during guest shutdown, independent of whether the service is running on the guest.

The VM's guest OS was freshly installed from Microsoft's ISO. No third party AV software nor drivers installed.

My host setup:
* OS: Ubuntu 20.04.1
* Kernel: tested with 5.8.0-41-generic (Ubuntu) and 5.9.16-050916-generic (mainline)
* System: HP ProBook 650 G8
* CPU: 11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz
* VirtualBox: tested with 6.1.16 (Ubuntu's repo) and 6.1.18 r142142 (Oracle's repo)

Conditions that do not cause a crash:
* running the VM in safe mode
* running the VM in a different host with Ubuntu 20.04.1, kernel 5.8, Virtualbox 6.1.18 r142142, CPU AMD Ryzen 9 3900X
* converting the VM's vdi file to qcow2 and running it with KVM

What have been tested without success (VM still crashes):
* running it with a different CPU profile, ""i7-6700K"" instead of ""host""
* uninstalling the VirtualBox Guest Additions
* changing the paravirtualization interface from ""Default"" to ""Legacy""

I have a pretty boring problem with virtualbox installed on Kali host and windows 10 as guest. When I use windows 10, after an indefinite time (sometimes immediately, sometimes after a few minutes of use), the touchpad or mouse stops working in both the host system and the guest system. More specifically, the keyboard works correctly, while the click of the touchpad or mouse does not work. The only way to fix this is to shut down the Windows virtual machine.

Reproduce:

2) Disable pinning on VirtualBox toolbar
3) Click on any Menu, let's take [Help] as an example.
4) Try to highlight (i.e. NOT selecting/clicking) [Help] -> [About VirtualBox...] -> (back to top again) -> [Devices] -> [Audio]  and do this *without* clicking the mouse again.

Result:
Toolbar will disappear approximately one second after [Help] is clicked, making navigating between different top menus impossible without  having to raise the toolbar again (done by clicking somewhere outside the now ""floating"" Help-sub menu and then moving mouse back to toolbar.

The only things that fix issue is nat network restart:

VBoxManage natnetwork start --netname nat-int-network-2

Of course, may be there are another ways... reboot particular guest or perform ""sudo  /etc/init.d/vboxdrv restart"" (requiring all VMs stop)... But the only way I found to fix issue (while not rebooting/stopping guest is restart nat network...
 
I have two nat networks (192.168.1.0/24 and 192.168.2.0/24). They hangs indpendently:

- First one, nat-int-network (192.168.1.0/24), connected to WinXP guest (single network adapter within guest) hangs rarely - 1-2 times per month. 

- Second one, nat-int-network-2 (192.168.2.0/24), connected to Windows Server 2012 Guest (one of two network adapters within guest, second one is openvpn tap0 interface attached to guest as Bridged Adapter) and hangs more often - 1-2 times per day... sometime 1 time per 2-3 days...

Windows Server guest is a loaded by 5-10 simultaneous RDP-sessions, but average load is quite moderate...

To be sure, that it has worked, I go back to my Linux host and type in a terminal the following:

{{{
VBoxManage guestproperty get ""MyWin7Guest"" /myproperties/myproperty
}}}
 Output:

{{{
Value: Word.Document.12
}}}

After, I now change the guestproperty (so that I can use it later again) with the command:

{{{
VBoxManage guestproperty set ""MyWin7Guest"" /myproperties/myproperty ""deleted""
}}}

Now I create a variable of the code above, (but not of the whole one, please compare them) because I need it later.
I do this in a linux terminal in my Linux host:

{{{
q='For /F ""EOL=H Tokens=2,*"" %G In ('
w=""'""
e='""""%SystemRoot%\System32\reg.exe"" Query ""HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.docx\UserChoice"" /V ""ProgId"" 2> NUL""'
r=""'""
t=') Do @""D:\NT3x\VBoxControl.exe"" --nologo guestproperty set /myproperties/myproperty ""%H""'
p=$q$w$e$r$t
}}}
So I have the code above in $p. I need this later:

{{{
$ echo $p
For /F ""EOL=H Tokens=2,*"" %G In ('""""%SystemRoot%\System32\reg.exe"" Query ""HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.docx\UserChoice"" /V ""ProgId"" 2> NUL""') Do @""D:\NT3x\VBoxControl.exe"" --nologo guestproperty set /myproperties/myproperty ""%H""
}}}



As the code has worked in my guest-system, I can now go one step further. I'll put the following code in front of it:

{{{
VBoxManage guestcontrol ""MyWin7Guest"" start --username XX  --password YY --exe
}}}

So that I have now the following whole code:

{{{
VBoxManage guestcontrol ""MyWin7Guest"" start --username XX  --password YY --exe ""%SystemRoot%\system32\cmd.exe"" -- 'cmd' /c start ""run this"" $p
}}}


I type this code into a terminal in my Linux host. Done.
What is the output? No output. No error. It looks like this if the code had been executed correctly.

To be sure, that it has worked, I type in my Linux terminal the following:

{{{
VBoxManage guestproperty get ""MyWin7Guest"" /myproperties/myproperty
}}}

Here is the result:

{{{
$ VBoxManage guestproperty get ""Win7NeuFurOfficeVersuch"" /myproperties/myproperty
Value: deleted
}}}

So: Why does this not work? Is this a VirtualBox error?

However, after upgrading to Version 6.0.16-135674 of VirtualBox, right-clicking on the USB icon does not show the list of USB interfaces/devices - instead it shows a menu list with the only entry of ""USB Settings..."" and a greyed-out entry stating ""No USB Devices Connected""

It runs KDE Neon (so Ubuntu 18.04 LTS under the hood). But I have the same problem on LMDE 3, LMDE 4, since VB 5.1.22.

On all systems, the linux app cheese works properly and displays the video stream from the camera. 

Windows clients have 2 webcams, and I can attach both to a client. The first does not result in a recognised device, the second does, but the video stream shows a blue rectangle. 

The laptop runs intel video and NVidia (MX1000 I think). Makes no difference, same effect. Audio is currently working perfectly, no detectable lag. VM performance is overall good. Windows VM's run with 2 cpu's, 8192MB Ram, virtio NIC and Hyper-V interface. No other issues. 

Under Linux the camera shows as 
{{{

VBManage list usbhost yields this for the camera

Attaching 1 from the menu doesn't do anything. Attaching 2 does, a webcam is detected, but a blue screen image is all I see.

An external USB webcam works perfectly. I am assuming it is related to the double entry, the client device detection seems to trigger on /dev/video1, rather than /dev/video0. The host seems to be indicating that /dev/video1 is not the one to use.

Started 2 different VMs using the following command

VBoxManage modifyvm xxxxx --autostart-enabled on --autostop-type acpishutdown --autostart-delay xx

Rebooted Host - everything launches correctly HOWEVER Windows Guest has NO AUDIO even though VM setting has Audio enabled. (With correct selections)

Issuing the following command: 

systemctl disable vboxautostart-service

Thereby disabling Autostart service

And rebooting and starting the VMs via script with the command:

vboxmange startvm xxxxx

Correctly allows guest audio.

There are a couple of annoying assumtions with Autostart as well. It FORCES headless (and audioless) operation of the client. Why? The Autostart feature should have a --type option as with the vboxmange startvm command (enhancement request)

A solution is to set ''""Graphics Controller""'' from ''""VBoxSVGA""'' to ''""VBoxVGA""'' and disable 3D acceleration. Then you have to shut down and restart your VM properly (by OS shutdown functionality).

However, ''VBoxVGA'' is not recommended and 3D Acceleration is not available. Should be considered as a bug!

The reader can still be accessed (for example, if a card is inserted certutil can still read it), but further interrupts don't reach the guest (if no card was inserted, newly inserted cards are not noticed).

Running wireshark on both host and guest shows that on both host and guest an interrupt in request is sent out and after 5 seconds a response from the device is received. After that, the guest has no further traffic, but on the host, a SET FEATURE request is sent and a response received.

My host system is Ubuntu 18.04 and I am running 10 Windows 7 VMs on parallel (headless).

The Cuckoo Sandbox application will stop a VM when it is done analysing a binary and will restore the specified snapshot. It will then power up the machine to start a new analysis.

After prolonged usage (around 4+ hours), one or more of the running VMs will become unresponsive and will not poweroff. The only solution I have is to restart the computer, as the virtualbox services will fail to reload.

Guest Additions: version=6.1.13-139990

Blue Screen is triggered each time User Account Control Activated to allow changes to windows.

This problem seems to be triggered by Windows 7 User Account Control (UAC). I can't even install simple updates to PuTTY, etc. without 6.1 causing a BLUE screen and reboot. This is triggered any time you are prompted to allow a change to your computer with UAC. The UAC dialog is displayed and the remainder of the screen is darkened. After choosing ""Yes"" to allow the change, the darken background is not removed from any open windows and about 5 seconds later BLUE SCREEN, and the Virtualbox 6.1 reboot screen is shown. 

This will occur if you simply attempt to start the command prompt with ""Run As Administrator"". I have 3 Minidumps collected if needed and the Event Viewer reports the critical error as ""Kernel Power"" (which doesn't look very useful)

As a test, I disabled UAC completely and attempted the updates to PuTTY again. With UAC disable, there is no problem. I can update software as normal without the Blue Screen on 6.1. So the bug in 6.1 causing the BLUE SCREEN crash is triggered any time elevated privileges are needed and UAC is activated. 

I have run this same VM for 5+ years and never had any problem with the 5.1 or 5.2 Virtualbox branches. There is something new in 6.1 that triggers a crash when Windows UAC is activated. 

Let me know if the Minidumps will be of any use or if there is other documentation I can provide and I'm happy to attach them.

I forced VBox down and searched for the problem, I found four VBox log files in the Logs directory for my VM, two had sizes of 30 GB and 90 GB!

I'm not sure whether such a huge log file should be useful for debugging, but guess VBox could emit an alert when these logs grow too much so that the user can pay attention and take some actions before the host system becomes unresponsive.

{{{

the time inside VM was going faster. But in VirtualBox 6.x it  doesn't work at all...

This happens because of this change:

{{{
    rc = CFGMR3QueryU32(pCfgHandle, ""TimerMillies"", &u32Millies);
    if (rc == VERR_CFGM_VALUE_NOT_FOUND)
        u32Millies = VM_IS_HM_ENABLED(pVM) ? 1000 : 10;

In 5.x default value of TimerMillies was 10 ms always (not 1 sec). But it is not the root of the problem.
The root lies near semaphore timeout calculation which trigger return from HLT. When WarpDrive is enabled this semaphore timeout calculated in wrong way."	gim

When, during the install of the VBox Guest Additions 6.1.12, the Direct3D support is selected (default=selected), on the subsequent reboot, after the user credentials have been entered and the login succeeds, the desktop fails to load.

The problem is independent of the setting of the 3D Acceleration in the VM Display Settings.

I tried the VBOXSvga driver with 3D support for the following guests :
- Windows VISTA
- Windows 7
- Windows 8
- Windows 10

I notice a lot of bugs, like Skype displaying a black window and more importantly transparency bugs and flickering. If I disable 3D support Skype remains buggy but flickering disappears. Now if I revert to VBoxVGA w/ 3D support enabled all is fine.

My host is as follows :
- Intel Core i7 4790
- 32 GB RAM
- NVidia GeForce 2070 SUPER w/ driver 430.40
- Debian Buster AMD64

I enabled the following environment variable as a workaround to the flickering bug we had w/ NVidia driver :

Sometime after upgrading to 6.1.x (don't remember the exact version - .2 or .3 or maybe .4 I think) my Windows 10 guests would randomly freeze shortly after booting.  I built a new from DVD/ISO Windows 10 1909 VM and it didn't/wouldn't freeze.  In comparing the output of ""VBoxManage showvminfo"" I noticed that I had different settings for [https://www.virtualbox.org/manual/UserManual.html#guestadd-balloon Memory Balloning] and [https://www.virtualbox.org/manual/UserManual.html#guestadd-pagefusion Page Fusion].

The freezing behavior didn't change with adjustments to the memory balloning settings, but did for page fusion.  If page fusion was enabled on the ""old"" Windows or the ""new"" Windows guest they would freeze.  Disabling page fusion on the guests and they wouldn't freeze.  I could repeat this Page Fusion '''Enabled''' = Freeze, Page Fusion '''Disabled''' = No Freeze.

- Arch Linux
- linux 5.6.3.arch1-1
- virtualbox 6.1.4-6
- virtualbox-guest-iso 6.1.4-1

Guest Information (both are reproducible)

- Windows 7 SP1
- Windows 10 LTSC 2019, Build Number 17763.1131

Steps to reproduce:

1. Cold boot the guest VM;
2. Take a online snapshot ""Snapshot 1"";
3. Shutdown the machine and restore to ""Snapshot 1"";
4. Boot the guest VM from ""Snapshot 1"" (directly into the Windows desktop);
5. Reboot/Reset the guest VM;
6. The VM resets, and shows a brief Windows Vista-style loading progress bar, and the VirtualBox (on host machine) freezes before crashing.

Notes:

- I have tried Windows 7 and Windows 10 guests (as decribed above), both are reproducible.
- If Guest Addition is not installed / uninstalled, the bug does not occur.
- If guest VM is cold booted (e.g. after step 4, instead of resetting/rebooting it, just shutdown and boot it), the bug does not occur.

Side note (may not relate to this bug):

After VB freezes/crashes, the RAM for guest VM is simply ""taken away"" from the host and cannot be recovered without a reboot of the host -- My host has 32 GB RAM, and each time a guest with 4 GB RAM crashes, there are 4 GB of RAM taken away from the host. After 7 crashes, 28 GB RAM are taken away from the host. I tried to shutdown Xorg server and there are only a few running processes left (none of them are VirtualBox), the host system still reports there are ~30 GB RAM used (top, htop, free... not cache/buffer, just ""used""). I have to reboot the host system to recover the RAM."	wzyboy

I've upgraded to version 5.1.8 r111374 using the Fedora 24 packages. I only have one Windows 10 VM that I've been using without issues for many months.

Since upgrading, every time I start VirtualBox (not the VM) I get the error saying: ""One or more disk image files are not currently accessible. As a result, you will not be able to operate virtual machines that use these files until they become accessible later. Press Check to open the Virtual Media Manager window and see which files are inaccessible, or press Ignore to ignore this message."".

The file is the VM's sole vdi file, but it is not missing, and if I click on Ignore the VM starts without any issues. Stopping and restarting the VM does not show the error again. Shutting down VirtualBox and restarting it shows the error again.

It is just an annoyance for now but perhaps it can develop in something worse.

this looks like a regression in 6.1.2 and 6.0.16 since I cannot duplicate with 6.0.14.
The VM simply disappears from the screen. Sometimes with no visible reason, but every few USB unplug/replug cycles. I found the USB part since I write some code that communicates to a USB device (CDC-ACM aka ComPort emulation). One of the actions does cause the device to reboot (on purpose).

Other times it sits in the background and when I want to open the VM window again, it is gone. Then sometimes it crashes immediately at start or shortly after. A host reboot brings it back to work (until it crashes randomly again).
Host and guest are running with latest updates.

19262	2D graphics performance issue when increasing the number of cores	Linux	VirtualBox 6.1.2	2020-01-24T12:13:58Z	2020-01-24T12:13:58Z	2020-01-24T12:13:58Z	"Hi,

to increase the performances of Adobe Lightroom in a Windows 7 VM, I tried recently to increase the number of cores in my Windows 7 VM and I noticed a serious drop in 2D graphics performances.

I first believed it was due to some regression in recent versions of VirtualBox, so I did some benchmarks (using PassMark 9) in the VM with VirtualBox 5.2.x and 6.1.x, and I got the same performance drop for 2D graphics, whatever the VirtualBox version, when I increased the number of cores in the VM. So, it's not a regression.

I have a very powerful machine, with 16 physical cores and 128 GB RAM, so I was able to plot the PassMark 2D score vs the number of cores (2, 4, 8 or 16) in the VM. Then I exported my VM to VMware Player, and I did the same benchmark. The attached image 'figure_2D.png' shows the results (higher score is better). As you can see, the 2D graphics score for VirtualBox linearly decreases as the number of cores increases. The 2D score is divided by ~4 between 2 cores and 16.

However, this is not the same for VMware, where one can see a small decrease of 15% between 2 cores and 16.

I also plotted the CPU score of PassMark vs the number of cores in the VM (image 'figure_CPU.png', higher score is better). For this benchmark, VirtualBox and VMware perform the same until 8 cores, but VMware gives a much better result for 16 cores.

I tried many parameter tweaks in VirtualBox but I was not able to improve the situation. I also tried with another PC that has less cores, and I saw the same performance drop...

Note that the performance drop I see in PassMark scores (in a Windows 7 VM) reflects what I see as a user in the windows 7 VM. This is not an artefact of using PassMark in a VM. For example, with 16 cores in a VirtualBox VM, moving a window is painfully slow. The CPU load is very high even when I do nothing, the fans are at maximum speeds, etc. Those problems do not arise in VMware player: the CPOU load is low, and the VM is very snappy, whatever the number of cores.

To me, there should be no interaction between increasing the number of cores and the 2D graphics performance. It's clearly a bug or perhaps a side effect of the way multicore processing is done in VirtualBox...

18879	Sound issues since 5.2.20 - Win98+Fifa98	Linux	VirtualBox 6.0.10	2019-08-29T15:06:03Z	2019-12-17T00:03:47Z	2019-12-17T00:03:47Z	"Hi,
I used to use a Virtualbox for quite some time on a private system to emulate Windows 98 SE with Fifa98 RTWC [2].
That was going fine but somewhen throughout last year I list sound.
First I thought it would be my messing with the system, but whatever I did it did not return.
After a while I did full re-install my system back to the last perfectly working virtualbox version (and a new OS install of the older Ubuntu 16.04).

Then I used the upstream downloads [3] to essentially do a version bisect when it was broken and found it.
6.0.10 (known bad)
5.2_5.2.32-132073 - fail
5.2_5.2.28-130011 - fail
5.2_5.2.20-125813 - fail
5.2_5.2.18-124319 - ok
5.2_5.2.16-123759 - ok
5.2_5.2.14-123301 - ok
5.2_5.2.4-119785 - dkms error on install
5.5.2_2.0-118431 - dkms error on install
5.1_5.1.38-122592 - ok (known good)

It is not that sound would be broken totally, e.g. windows startup sound works and playing wav files. But when starting the game sound fails (no error message). Back out of the game Windows sound works still.

I think this uses DX5 for sound, but I'm not sure.

I tried to replace the (virtual) sound card from soundblaster to AC97 but that didn't help either.

I wonder what debug data I could collect for you to get this understood and fixed at the head of 6.x series so that I can upgrade again?

P.S. I started this in the Ubuntu tracker at [1], but after the debugging we did I guess it is time to reach out here.

On Solaris, Linux, and FreeBSD (BSD using the OSE release) hosts, when a VMs is in seamless mode (like Win 7 and these same Linux/UNIX variants), the VB mini ToolBar is hidden behind the guest's toolbar if they are on the same edge of the screen.  There is no way to bring it forward, even if you set your guest to auto-hide its toolbar.

Attached log is from Windows 7, but it also happens with other guests that have a desktop that works well with seamless mode, like MATE or Gnome2.

I have experienced issues in the past with Shared Folders, but in the past it only seemed to affect the Guest systems. This issue is hard to troubleshoot since the Host system freezes, I can only resolve it by unplugging the power. I have tried using the SysRq keys to no avail. In troubleshooting the issue, I have stopped all other host applications except VirtualBox and disconnected the Shared folder. For a week, I did not experience any freezing of the host the system. If I connect the Shared Folder I will randomly experience a hard freeze in a couple of hours or a couple of days.

The host system has 16GB RAM and 4 cores. I am using 4GB and 2 cores for my Windows 10 1909 guest.

I do not know how to troubleshoot this any further since the Host system hard freezes, I do not get any indications of problems in any of the host logs. It most likely freezes before documenting the problem. I welcome any tests or settings which you want me to implement in order to determine the problem or fixes.

I need to use the old Windows Movie Maker and therefore I set up a Windows Vista machine.

Issue:
Movie Maker starts fine after some tinkering, but the guest OS crashes if anything is done with the timeline.

Things I did:
- Installed Windows Vista
- Installed all available updates (+ Firefox)
- Installed guest additions 6.0.14 multiple times with different settings, inside and outside of Safe Mode
- Added one shared directory

VM settings:
- 2 GB RAM
- 2 CPU cores
- 3D acceleration enabled
- 2D acceleration enabled
- VBoxSVGA
- 256 MB graphics memory


At first, Movie Maker did not start at all because it needs graphics acceleration. Also, it didn't start when I installed the Guest Additions with regular Direct3D support - dxdiag.exe reported that there was no Direct3D acceleration available.
Installing the Guest Additions with the experimental Aero (WDDM) support failed once in safe mode, but succeeded on the second try.
Movie Maker starts fine now, but as soon as an item is added to the media timeline or moved within it, the Guest OS freezes for a few seconds, then reboots.

When a VM is started and is displayed in full screen only part of the screen of the guest is visible (see screenshot).

When VBox windows are moved to the other display and are maximized everything is OK again.

I'm attaching a log file for the ticket, as well as the VM Guest configuration file. As far as I know, everything is up to date and configured correctly.

I'm also attaching the output of lspci (for my host's graphics card) and a partial dump of dmesg as there are some warnings from VB kernel modules.

Some background:
Basically, everything seems to be working intermittently graphics-wise. All the issues seem to be occurring due to crashes inside C:\WINDOWS\system32\VBoxSVGA.dll, including frequent windows in Desktop Window Manager (dwm.exe). 

Additionally, sometimes I am getting the error ""Display driver failed to start; using Microsoft Basic Display Driver instead. Check Windows Update for a newer display driver."". When this happens I have no choice but to restart because the guest's screen becomes totally black with a working cursor and a blurred version of the VB bios screen overlayed in white. There is no way to resolve this without a reboot.

When things get really bad, pretty much all apps refuse to launch (though the ones already launch still work) and they fail silently (this is really ironic and frustrating as this includes debugging apps), though for each attempt I see an error relating to VBoxSVGA.dll in the Windows Error Log. I am attaching several days worth of Windows Error Logs (Application Logs) in XML format in the hopes they contain some information. I'm also attaching an HTML export of the Windows Error Reports that were generated. (Unfortunately I didn't have saving minidumps enabled at the time.)

When this whole ""nothing will start"" phenomenon occurs a program that I'm frequently trying to use -- a 3D modeling program called Autodesk Fusion 360 -- actually freaks out because it will keep trying to restart a Chrome WebView process ad infinitum (obviously the ad infinitum bit isn't on VirtualBox). I've included a stack trace from a minidump of one of these crashes as it's one of the few minidumps I have. (I can't attach the minidump itself as the memory contains proprietary content.) 

If anyone could offer any help, it would be greatly appreciated. I'm happy to assist with debugging this in any way I can.

I attempted to change my Graphics Controller which placed my VM in an unusable state as it kept crashing the Windows GUI.  I put the guest into SafeMode to install the guest additions which allowed me to boot.

Now when using the guest I am unable to view applications as they render as black boxes.  Examples of applications not working: Google Chrome, Microsoft Outlook, just about anything not part of Windows OS.

I have also tested VMSVGA and this is not working either.  My Display configuration is:

I copied over my Windows 10 VirtualBox guest VM from the old system (Intel i7 8-core) to the new system. The Virtual Box guest boots without issue using the old settings (8-processors). However, if I shut down the VM and change the settings to a higher processor count (I have tried 12 and 14 cores), the VM does not progress very far into its boot: I see a blue background and the windows icon. None of the VirtualBox activity icons at the bottom of the Guest window are active: all dark. That is it. There is one Virtual Box process that continues to run at 100% cpu usage until I kill the VM.

I'm using shared folders in Windows 7 x86 guest and Mentor Expedition PCB hangs if I try to open project, placed on shared disk.

This behavior is not observed if I replace guest additions with version 5.2.22. Versions 6.0.0 and 6.0.2 show exactly the same behavior.

Other read/write operations doesn't show any problem (at this time).

I've tried to investigate hanging I/O operation in Expedition PCB and with the Process Monitor (Sysinternals) found, that last unfinished call was '''QueryDirectory'''. This event description from ProcMon is

18675	File corruption on shared folder - Linux host + Windows 7 guest	Linux	VirtualBox 6.0.8	2019-05-24T17:16:26Z	2019-06-05T00:38:48Z	2019-06-05T00:38:48Z	"Setup :
Host : Ubuntu 16.04 x64
Guest : Windows 7 x64
Shared folder (on ext4 partition) between host and guest

I'm using a Windows 7 virtual machine only for Adobe Photoshop CS6 x64.

Before v6.0.8 I installed v6.0.6 only briefly, I had to revert back to 6.0.4 because of the mouse integration bug. So I for the present issue I installed 6.0.8 over 6.0.4.

I encountered a strange behaviour with the shared folder I'm using to exchange files between the host and the guest. 
In Photoshop CS6 x64, after I installed VirtualBox v6.0.8, sometimes Photoshop tells me it couldn't read the TIFF files I had worked on before. And when it could, sometimes the content was scrambled.
I checked my images in other software (under Windows ''and'' Ubuntu) : correct.
I opened the files in the VM with Photoshop CS6 x32 this time : correct.
I checked my TIFF files with an utility called jHove, which checks the TIF file integrity : no errors.
So my image files are without flaws. I can save them in Photoshop but not read them back, at least in the x64 version. Weird.
I also copied the files directly on the guest : this time Photoshop CS6 x64 was happy.

For 2 days I have tested many things. It only occurs in Photoshop CS6 x64, when I'm using the shared folder.

So I decided to revert back to VirtualBox v6.0.4, and dang! Photoshop CS6 x64 was happy again with my files...

So my conclusion is the problem comes from the shared folder functions, but only when reading my files, not when I'm writing.

I'm including my v6.0.4 last log file, I didn't think about saving one when I was under v6.0.8 sorry."	Parazythum

Several shared folders set up on the Host. Shared Clipboard & Drag and Drop set to Bidirectional. VB.log attached.

Problem: Copying a directory FROM the Windows 10 guest to a Linux Shared Directory results in only the first directory being created. No files or sub-directories are copied. This has only been the case since Windows 10 Creator's Update installed. The last version that did not have this problem was 5.1.22 but that was before the Creator's Update installed.

Steps to reproduce:-
1. In the Windows 10 Guest open two instances of File Explorer.
2. Set one to a directory containing files on the Guest and the other to a Shared Folder on the Host.
3. Drag the Windows directory to the Shared folder.

I'm finding nothing is transferred except the top-most directory but none of it's children.

The cameras we use are designed for continuous running in a factory and so the reset being issued is causing them to go through a full reset to ensure that they can be recovered in a fault case. This means that they are disconnecting from the host causing VirtualBox to lose track and fail to attach them to the guest. 
If I set a USB filter it gets stuck in a loop of constantly resetting the device and failing to attach it.

Is it possible to configure VirtualBox to disable the new device reset feature either globally or for a specific device?"	Dan

I've remarked that since VirtualBox 5.0 (and further versions) any Windows guest with DWM has a very annoying blinking effect. It's very proeminent on Windows 10, 7 and Vista guest, much less on Windows 8 guests.

This problem appears especially once Firefox has been started in the guest, but also with Windows 10 start menu or if you start CCleaner in Vista with admin privileges. It is also much more likely to occur if you start the VM, then switch to another host window, and then switch back to the VM window.

Under Windows 10 you can also the problem when starting Age of Empires 3 in the guest.

Note that w/ VirtualBox 4.x such blinking problem did not appear.

Guests affected :
Windows 10 x64, Windows 8.1 x32, Windows 7, Windows Vista, all with guest additions 5.1.2 installed.
256 MB of VRAM allocated to each VM.
All updates installed to each VM.

Host :
Debian GNU/Linux Jessie 8 stable with all updates installed, including backports (Kernel 4.6.74). Arch AMD64
NVidia binary driver 367.27 (but actually the issue also appeared with older versions of the driver incl. 352.xx)

and then I started Win10 : just a black screen appeared, nothing else.
I could nor stop it, neither kill it from a terminal. Then I even had my Linux host to force to stop with the power button, too.

TESTS
1. After a new Linux host start I started Vbox again (now without any modification) and then Win7 guest. Same result as above.

2. I deleted completely VirtualBox 5.2.24 with all its files, even the VM-s from my laptop, (they were exported not long ago to an external drive). Then I installed VirtualBox 6.0.4 and its Extension Pack, and imported my 2 Windows VMs. They both worked fine again. I installed the apropriate GuestAdditions in both. Still ok. I could work with them well. 
Then I added myself to the vboxusers, rebooted Linux and started VirtualBox again. I set a new USB filter for Win10 and started it. Black screen again which could not be killed, and Linux could not be stopped. 

3. After a new start I tested my Win7 guest as well, neither works it any more. Black screen, stuck, Lx can't be stopped.

I think some Vbox configuration goes bad... I use Vbox since many years, and I do not rememeber similar problem. In a formerly Vbox version I could set USB filters, however I do not remeber the version number unfortunately. Anyhow, I appreciate Vbox very much, it is an excellent work.

18349	Audio getting muted in screen reader installed on Windows 10 guest (Virtualbox 6.0.2)	Linux	VirtualBox 6.0.2	2019-01-22T17:45:46Z	2019-01-22T17:45:46Z	2019-01-22T17:45:46Z	"I've upgraded recently from Virtualbox 5.2.6 to 6.0.2 - Archlinux is the host and Windows 10 the guest system. As I'm totally blind, I use a screen reader to access the computer (NVDA 2018.4.1 installed on the guest). Both virtualbox-ext-oracle and guest additions are up to date.

After upgrading I noticed that the screen reader gets muted for a while and starts speaking again. The problem happens suddenly and frequently. When it gets muted and I switch to the host window and go back to the guest, it starts speaking again and after some seconds (or minutes) the problem repeats.

I've already confirmed that the problem isn't related to the screen reader; its commands continue working even when it is muted and there are no logs showing a NVDA crash. Initially, I thought that the entire audio was being affected by the problem, but when I play a video (from Youtube, for example) in background and continue to use the screen reader, surprisingly the issue doesn't happen (after stopping the video the problem back to arise as before).

Are you aware about some known issue that may be related to the aforementioned problem?"	alan-ghelardi
18346	Crash after reboot Windows 10 guest	Linux	VirtualBox 6.0.2	2019-01-22T11:13:04Z	2019-01-22T11:13:04Z	2019-01-22T11:13:04Z	"Hi,

I rebooted a Windows 10 guest because a shared folder was showing up twice (I have reported this issue in the Windows Guest forum) but it crashed. After powering down the guest it boots normally.
Host OS is ubuntu version 18.04.1, Virtualbox version is 6.02, guest OS is a new install of Windows 10 1803 with the 6.02 guest additions. 
I have attached the logs for review.

18334	Windows 10 guest freeze or crash	Linux	VirtualBox 6.0.2	2019-01-19T09:11:43Z	2019-01-20T07:17:32Z	2019-01-20T07:17:32Z	"After update to VBox 6.0.2 a Windows 10 64bit guest always freezes or completely crashes when VBoxSVGA and 3D acceleration are chosen. It happens as soon as Skype for Business starts on the VM.

Additionally I've got problems with keyboard grabbing as well as graphics (Outlook 2016 moves cursor to and fro while typing with hardware acceleration off but Excel opens files only when it's off).

Disabling 3D acceleration in the VM settings seems to solve the problems.

worked with VirtualBox 5.2
Issues that the second screen has only 1280x1024 instead of 1600 x1200

That was working before I run the machine today.I have not worked for month with the target.

An update to 5.2.22 was announced. I clicked it away. Then I got the small issue mentioned above. I decided to do the update. On the homepage 6.0 was announced instead of 5.2.22. So I downloaded the deb-File for 16.04. Ubuntu Software Center could not install it. Old version has been still installed at this time. But then followed the instructions on the page and downloaded and installed it by command line adding the repo for it.

After starting my Windows 10  machine, there was only two very small VGA screens left. After trying to reinstall the vboxguestadditions, there was only one screen left at least with 1280x1024 resultion.

There have been errors installing the guest additions they stuck installing some driver fro VBoxVideoW8 for a ""hardware that is currently not present"". Please see the log.

How can I rescue my windows copy. Because I think something was messed up during installation of VB 6.0 or the guest additions. I meanwhile deleted the vbox in /usr/share/virtualbox but after reinstallation error stays stable. I am not able to continue working on my projects
.

In the end I deinstalled 6.0 and get me a copy of 5.2.22.

Please help save my work, because last time it all worked perfectly!

using the latest Win10 build causes a problem when using two displays: The cursor is not in place 'where the action is' (sorry, don't have better words to describe it). There is kind of an offset that gets larger the more I move the mouse to the right. You point the mouse to a desktop icon, and another icon to the right gets highlighted. Happened after updating the guest to Win10 1809. With one display all is fine.

18157	keys repeat (example: moving the cursor) will make shift or control key stick	Linux	VirtualBox 5.2.10	2018-11-29T03:14:51Z	2018-12-05T01:56:28Z	2018-12-05T01:56:28Z	"Hello,

I have a problem with the indiscriminately activation of caps-lock and/or ctrl while typing, moving the cursor or selecting text.

This symptom will happen if I use one key very long (selecting text...) . (Not often and not exact reproducible, but several times a day.)


'''Host is:'''
- Linux Mint 19 Tara / Cinnamon (freshly installed 8 Weeks ago)
- 2 different computers (physical identical and with similar installation) with the same problem!
- 16 GB Ram, i3 CPU
- ASRock H370M ITX ac / BIOS v3
- Onboard/CPU graphics
- Virtual Box 5.2.10


'''Guest is:'''
- Windows 7 (several installations (old converted computer and freshley installed also))
- Guest Additions are also installed
- USB Additions are also installed... but the issue was earlier as this installation

- no test with Linux as guest!


'''Annoying:'''
- text will be selected if virtualbox thinks that shift is pressed
OR
- the cursor jumps by word like the ctrl key is pressed

This can change in ""one session"" of this issue. (selecting ... jumping ... selecting)

 
'''
I'm able to ""solve"" the problem with:'''
continue with selecting text!  cursor right ..... cursor left ..... cursor up and down.... 
watching if text is selected (blue) while the cursor is moving the text.

No typing of Letters is possible, because every character is combinated with the ""virtual ctrl"" or the ""virtual shift"" key. Result: typing ""s"" is combinated with ctrl to: save my document... and so on.

Clicking with the mouse (on a existing document in task bar) will cause to open a very new document. I'm not able to get into an opened document with the mouse via taskbar. Every mouse-click will open an new instance of the program.



'''I can see ""this"" before the issue begins:'''
- If I move the cursor along the line the cursor has a certain speed. Very short time before the issue starts, the speed will reduce a little bit.

- While the issue is active the cursor has his regular speed.

short time before the issue ""ends"" (for an hour or two or 15 minutes) the speed of the cursor is reduced  to zero. Sometimes the issue has a continuation. Sometimes the issue ends and regular work is possible.

This can last up to 5 minutes!

The reboot of the guest is no real solution. Sometimes the issue takes part within 5 minutes.

The time itself is no factor: If I leave the computer for a while, the issue is still alive.
ONLY continuous run over the timer will solve the problem.


'''the keyboard''' 
is working fine in Linux! No ""virtual ctrl"" or ""virtual shift"" key.


'''Any open questions?'''
- what is needed? (log-files, list of installed programs, ...?)


''Any ideas?

I have properly working Virtualbox and full list of USB devices available inside Windows guest OS. The problem I face is that a specific USB serial device 0000:a180 is not properly exposed by ""VBoxManage list -l usbhost"" and respectively not properly passed-through to Windows guest.

11590	Win 7 VM slows down when presenting in GoToMeeting	Linux	VirtualBox 4.2.8	2013-03-13T22:24:02Z	2018-11-14T23:53:24Z	2018-11-14T23:53:24Z	"This bug has been on-going for me since the January time frame. The basic issue is that when using GoToMeeting in a Win7 VM, and if my VM is made the presenter, then graphics slow down to the point where the VM becomes unusably slow. The VM can be in a meeting with someone else presenting and it's fine. Only slow when the VM becomes the presenter. Slow means the cursor is unresponsive, gui interaction inside the Win 7 VM is very slow, cursor flicker. Pause the screen so that it's not being updated and the VM becomes fast again.

I've seen this problem on 3 Win 7 VMs, two on this machine and one on my laptop. Both hosts are Gentoo Linux 64-bit, mostly stable and completely up to date. 

Both machines can boot Win 7 natively and have not problems. VMWare running Win XP on the same machines has no problems.

I am going to attempt to attach a log file of the VM booting, starting Google Chrome, starting G2M, having the problems and then shutting down the VM."	Mark Knecht

Guest: Windows 8.1 (also appears to affect any other guest)

Audio Controller: Intel HD Audio

Microphone is enumerated by the guest, but it is always silent. On occasions fiddling with microphone driver enumeration (i.e. toggling ""Show unplugged recording devices"" several times, going to its properties, etc) can even crash VirtualBox (rare, happened to me only twice).

PulseAudio shows VirtualBox has requested and received microphone and speaker.
I've also tried the ALSA driver, same result. Couldn't try OSS driver (immediately aborts VM, didn't look much into it; I assumed either I had a missing dependency or the OSS device couldn't be grabbed)

I tried AC97 audio controller but Windows 8.1 won't install drivers for it.

Useful info:
* Problem shows in official virtualbox-5.1_5.1.2-108956-Ubuntu-xenial_amd64 (using matching extension pack & Guest additions)
* Problem persists in test build VirtualBox-5.1.3-110032-Linux_amd64.run (using matching extension pack & Guest additions)

The aborting generally happens when running Lotus 123, which is a spreadsheet program. I have tried the standard ideas of turning off 3D/2D acceleration, but the crashes continue to happen.

I worked around the problem by issuing this command:

''However'' - and this is problem 2) - once the VM was using my native resolution, setting the scaling within my Windows 10 Guest to 150%, and especially to anything higher, causes pointer strangeness in Word 365. For, once the pointer changes - changes upon mouse-over of an icon in the Word ribbon - it does not, for some time or occasionally permanently, change back.

17791	Guest VM becomes unresponsive after 2 or 3 days continuous uptime	Linux	VirtualBox 5.2.12	2018-05-30T20:35:20Z	2018-09-04T18:09:22Z	2018-09-04T18:09:22Z	"Using CentOS 7.5.1804 host and Windows 7 guest with dual monitors full screen, USB mouse.

After the VM has been running continuously for about 2 or 3 days, the VM starts going into an abnormal wait state. The cursor can be moved with the mouse, but it changes from a pointer to a blue circle after clicking on something. At first, the ""wait state"" circle is short-lived, changing back to the normal pointer after less than a second. The problem gets worse over time and the cursor will begin to flash between normal pointer and blue circle a few times and then for longer and longer intervals. The longer I let it go, the more time it spends in the wait state. When the cursor is displayed as a blue circle, any button press on the mouse is ignored as well as key presses on the keyboard, although there was one time that I must have been clicking all over the place trying to get a response and on killing the VM, those clicks seemed to appear in the Linux host.

If I let the problem persist and don't reboot the VM, eventually the VM becomes completely unusable. The cursor stayed as a blue circle for over 30 minutes one time before I gave up and killed it. I have to reboot the VM to clear the problem and when I first started doing that, I would halt the VM and also reboot the Linux machine. More recently, I have only been shutting down the VM and restarting it. Earlier today, I shut down the VM and restarted, but noticed I was still having the problem. I shut the VM down again, exited the VB GUI console and made sure all VB processes were stopped, then started it back up. That cleared the problem.

When the guest system enters a wait state hang, CPU utilization on both host and guest still seem normal; no CPUs are pegged. When the guest seems to have entered a permanent wait state, it is still getting work done. I have had this happen when the Windows task manager was running and showing the CPU usage history. I had it set to slow updates, meaning it should update every 4 seconds but I was getting updates more like around 16 seconds.

I had been using the paravirtualized network driver and wondered if that could be a problem, so changed to the Intel PRO/1000 MT Desktop adapter with no change.

I first started having this problem in later versions of 5.0 on CentOS 6 and I had other problems with 5.1 so didn't run that for any appreciable amount of time. I have captured trace files of a hung VM if that could be useful to anyone.

I see similar reports on the forum about lost mouse clicks, and dual monitors may be one of the conditions required to reproduce.

14923	`guestcontrol run` memory leak in host	Linux	VirtualBox 5.0.10	2015-12-12T00:43:40Z	2018-08-28T09:12:25Z	2018-08-28T09:12:25Z	"#14850 is the only other open memory leak I can find.  That looks like a guest side leak associated with disk IO, but this is a host side leak associated with `vboxmanage <name> guestcontrol run`

I'm running an Ubuntu host, and a Windows 7 (all updates installed) guest.  The guest is given 1 CPU and 2GB of RAM, but I can get it to consume >8GB of RAM (enough to have the Linux OOM system kill it).  I verified that the guest stabilizes at using ~650MB of RAM in this case, so the leak is definitely on the host side.  To trigger the leak, I first start my VM:

{{{
ian$ vboxheadless -startvm win-7-pro-loaded-base
}}}

Then I run: 
{{{
ian$ vboxmanage guestcontrol win-7-pro-loaded-base run --username administrator ""C:\\Windows\\System32\\ping.exe"" -- ""-t"" ""localhost"" 2>&1
}}}

You can accelerate the leak by running many of the `vboxmanage` commands in parallel.  With 6 running, the `vboxheadless` process went from using 3GB to 5GB (RES in `htop`) RAM in 12 minutes.

Attached are the VBox.log from one occassion of running this, along with an image of `vboxheadless` memory use over time with 6 `vboxmanage` commands running, and an image of the stabilized guest memory.

I also attached a zip of running:
{{{
sudo strace -i -ff -p <vboxheadless first thread PID> -o strace_output/strace
}}}

for a few minutes while the 6 `vboxmanage` commands were running.

Let me know if there's more information I can supply, or if you'd like me to try anything.  I started along the path of building and running virtualbox from source so I could poke around, but I'm having a few issues.

Thanks in advance for all of your help!"	iano

{{{

Running these commands will not return anything (the command ""freezes"" and I have to hit CTRL+C to aboard it). This happens every 1-3 days.

The VMs are still running (and I can connect to them via vbox RDP), but I'm not able to control them on the host anymore (via vboxmanage). The only way to get it running again is to kill all VMs (killall VBoxHeadless) and do a complete reboot of the system.

I use ""VirtualBox Graphical User Interface Version 5.1.38_Ubuntu r122592 © 2004-2018 Oracle Corporation (Qt5.5.1)"". And using Windows XP on it. I use my own program to track the accuracy of the time, and sometimes I notice that Windows is weirdly tuning the time. For example I attach today's graph of adjustment.

It can be seen that the detuning runs on some kind of sinusoid, and then at some point it goes out on a flat line. Then, when the detuning builds up, it for some reason again goes to the sinusoid of an unacceptably large amplitude, and then again sets the normal time. On the vertical axis - milliseconds. That is, during these sinusoid detuning reaches 15 seconds - it's terrible, I think. 

I tried to disable the vm module on WindowsXP, and the tuning is disabled, but the clipboard between vm and my machine stops working as well - thats not good.

So, I have a couple of questions:

1) Why is there such a strange sinusoid used in the time adjustment (which uses the SetSystemTimeAdjustment) instead of a rapidly decaying exponent?

2) can I disable this strange time adjustment without disabling the clipboard?

This leads to several consequences:
* Text is barely readable (glyphs simply can't be simply upscaled using whole-screen image scaling)
* The guest OS is presented a lower resolution than the host's monitor would be capable of, so even HiDPI-aware guest OSs have to run in super-ugly upscaled mode.

This works fairly well, but there is one slight issue: The group ownership of the /dev files corresponding to the above mentioned partitions changes after I complete the VirtualBox session. The following sequence of shell commands and output should illustrate what happens:

{{{
[toralf@osl-97214 ~]$ ls -tlra /dev/sda[123]

Note that the first output represents the way everything looks after a reboot.

This is a bit annoying as it means I can't give a regular users access to the Windows installation via addition to group ""disk"". Or rather, I can, but there can only be one VirtualBox session after each boot, unless someone intervenes. I guess I can add users to ""root"", to, but I'm somehow less comfortable doing that."	toralf

All attempts to condition the behaviour of the VMs fail, and the desktop of the VMs appears small and surrounded by a black margin to the right and below.

I have (obviously) tried the File-Environment-Display settings, auto resize guest, VBoxManage setextradata, etc. but none of these works.

It is possible to increase the resolution a little, but this setting does not persist, and is never in line with the actual resolution. In the Win10 machine, the pointer is also misaligned, making it impossible to use.

Really odd behaviour we are getting from our VMs. We have 3 VMs running windows 7 and each has a dongle that grants access to proprietary software. 2 dongles grant access to HASP software and 1 grants access to Windfarmer. These usb devices are incorrectly named in Virtual box which is causing some confusion, We can only use Windfarmer software when one of the ""HASP"" dongles is connected and vice versa.

Not sure how/when this began happening or why. This would be a purely aesthetic problem but the two HASP dongles are identical and cannot be distinguished between each other using the USB filter so occasional they are assigned to the incorrect VM which means we have to manually fix it.

 1. Using Kubuntu Trusty host, Create XP VM in ≤ 5.1.30. Seamless mode should work fine (see expected results below).
 2. Upgrade to 5.2.2. 
 3. Boot XP guest.
 4. Switch to seamless mode.

== EXPECTED RESULTS
 1. Guest desktop disappears.
 2. Host window decorations disappear.
 3. Space is drawn on the host desktop for the guest windows.
 4. Guest windows act like host windows, responding appropriate to movement, e.g.
 5. Guest windows appear normally.

== ACTUAL RESULTS
All of the above assumptions are correct except for the 5th one. The space is drawn, the windows act normally, there are no other decorations, but every guest window is a visual nightmare. See attached screenshot.

== NOTES
 * Host is Kubuntu Trusty running the 4.2.0-42-generic kernel and is fully up to date and restarted.
 * Tested with versions from the repos at download.virtualbox.org: 5.1.30-118389~Ubuntu~trusty and 5.2.2-119230~Ubuntu~trusty. In both cases, the expansion packs and guest additions were updated accordingly.
 * Guest video memory is maxed out.
 * Turning acceleration off, enabling both 2D/3D or one or the other had no effect.
 * Initially the guest was using multiple monitors. Disabling the virtual screen had no effect. Lowering the number of monitors to one had no effect, either.
 * Full screen, scaled, and normal modes all function appropriately.
 * VM has been running for years with no problems.
 * Logs are attached. You should see the switch to seamless at 0:00:48.457777."	Walter Lapchynski

* virtualbox-guest-iso-5.2.2-1
* virtualbox-host-dkms-5.2.2-2
Start the Windows 7 guest in Safe Mode, install the Guest Additions, select Direct3d support, agree to install only Basic Direct3d support, reboot the guest, then start PokerStars (the most recent build is 20294) and click the ""Challenges"" button in the menu. This resulted in the window freezing for several minutes (I had to force-kill it).

The program similarly hangs when sitting down at a table, which is the more serious part; the Challenges window just provides a more convenient way to test the issue.

Using all 5.2.0 VirtualBox components instead of 5.2.2 made no difference (PokerStars froze just the same).

It does not seem specific to the PokerStars build, as trying it with an earlier build of PokerStars made no difference.

After having used 4.X with great pleasure for a long time to debug Windows USB issues in Linux (Fedora), i have hit a snag in the 5.X series.

The problem is always the same. If i start streaming ISO packets they get stuck after a very short while. In the early 5.X builds the entire VM would implode, but now it just hangs the USB stream until i unplug the device.
There is some kind of bug in the 5.X USB implementation. If its the VB drivers in Linux or the virtual drivers in Windows is not clear to me.

Has anyone else seen this problem? I have tried all combinations of options i could think of but the problem persists.

I have attached a Wireshark trace that shows the problem up until the hang. Note that when this happens the *entire* USB freezes up, not just the ISO packets.

Thanks,

With VirtualBox v5.2.2 and its extension pack installed, and after booting my Windows XP guest VM (with corresponding v5.2.2 guest additions installed), when I start Poser 6 or 7 (the only two versions I got) on a Windows XP (32 bits) guest running on a 64 bits Linux host, the program hangs shortly after starting, on the startup screen, and Windows reports the program as ""non responding"" in its title bar. After a few more seconds waiting, the window of the program turns white and it stays stuck forever like that.

If I reinstall the v5.1.30 guest additions (still keeping VirtualBox v5.2.0 and its extension pack) Poser then works fine again.

Probably an issue in DirectX support ?

17259	Upgrade 5.1.28 to 5.2 headless guest can no longer be accesses, video performace degraded	Linux	VirtualBox 5.2.0	2017-11-10T05:43:40Z	2017-11-15T06:18:24Z	2017-11-15T06:18:24Z	"Upgrade from 5.1.28 to 5.2 (Arch x86_64 host) leaves headless Win7 guests unable to capture mouse or keyboard regardless of host-key use until virtualbox is started on host machine and guest launched via gui interface and windows guest addtions updated from 5.1.28 to 5.2.

PUEL from VirtualBox-5.2.0-118431-Linux_amd64.run with Oracle_VM_VirtualBox_Extension_Pack-5.2.0.vbox-extpack

This is unexpected new behavior. The expected result is that following update, the headless client can be started and accessed as normal remotely via rdesktop and guest additions updated from within headless guest as has been the case with all prior 5.1.X updates. 

An update to 5.2 on the host will leave Win7 (and probably others) unable to access the headless guests remotely. There is no way to have the mouse or keyboard captured when first accessing a headless Win7 guest remotely after the 5.2 update on the host. The login screen is displayed and visible, but there is no way to interact with it -- with or without host-key use (currently the default rt-control)

When virtualbox is started on the host machine, prior guest additions are ignored and prior setvideomodehint resolution and color depths settings are ignored. The default capture host-key dialog is shown as if no prior guest additions are present.

If the incompatibility between 5.1.2X guest additions and 5.2 is a known issue, this should be clearly stated in the changelog as it impacts remote headless guest access that guest users cannot correct without access to the host machine.

Secondly, after 5.2 guest additions are installed from the host, and the guest and virtualbox shut down, the guest can then be restarted headless and access remotely. setvideomodehint on the host must be reset to restore 32bit display color depth for remote access. Video performance within the headless guest is degraded compared to 5.1.28 with lagging window moves within the Win7 guest and artifacts at the window corners on repaint that were not present in 5.1.28. (this is with 2D accell only, no 3D or aero active)

16843	WDDM driver does not validate custom video resolutions, causing graphics freeze on boot	Linux	VirtualBox 5.1.22	2017-06-19T01:11:11Z	2017-11-14T10:55:32Z	2017-11-14T10:55:32Z	"See investigation on [https://forums.virtualbox.org/viewtopic.php?f=7&t=83489 this forum post]

For some reason (possibly the tiling WM resize bug on Linux) the custom/transient display resolution can be set to a very small size (e.g. 400x191) and this small size is saved to the registry in Windows. Once the WDDM driver is installed, Windows will try to add this mode to the target modes in the VidPn framework. This fails and the boot sequence appears to freeze on the Windows splash screen, rendering the VM unusable.

A workaround is to install the Guest additions in safe mode, then edit the registry keys storing the custom resolution to be a larger size, e.g. 800x600. See the attached image.

Reproduced on both OSE and non-OSE versions of Virtualbox, 5.1.22 with corresponding extpack and Guest Additions ISO installed.

It becomes completely unresponsive. The clock (showing seconds) no longer advances by 1 second, instead it jumps every few seconds showing that the VM is hung most of the time. The guest window even darkens periodically showing that the host detects it as unresponsive.[[BR]]

For some applications, it's enough to open it without loading anything (Word 2016 or Excel 2016 for example). The older versions (i.e. Word 2013 or Excel 2013) can be opened, but if a document is loaded, or in the case of Excel if any single cell (or a range of cells)  is copied to the clipboard, the guest becomes pretty much locked. It is possible with persistent clicks on the close button to terminate MS Office application and regain guest responsiveness, but this usually takes minutes as the VM pretty much doesn't respond for most of the time.[[BR]]

I recently updated to VirtualBox v5.2.0 RC1 to give it a try and see if my VMs could still work fine in it. I was well inspired, since I found a show-stopper bug (at least for my needs).
So, I installed VirtualBox v5.2.0 RC1, the v5.2.0 RC1 extension pack, booted my Windows XP guest VM in fail-safe mode, installed the VirtualBox guest additions (which, strangely, identify themselves as being v5.2.0 Beta 3 additions, instead of RC1...) with DirectX support.

Once the VM rebooted, when I start Poser 6 or 7 (the only two versions I got) on a Windows XP (32 bits) guest running on a 64 bits Linux host, the program hangs shortly after starting, on the startup screen, and Windows reports the program as ""non responding"" in its title bar. After a few more seconds waiting, the window of the program turns white and it stays stuck forever like that.

I then reinstalled the v5.1.28 guest additions (still keeping VirtualBox v5.2.0 RC1) and found out that Poser then works fine again.

Probably an issue in DirectX support ?

I was previously running an XP Guest x86 using VB 5.1 under Windows 10 Pro x64. Everything was fine. I had virtualization, nested pages, etc. enabled.

I then installed VB 5.1 under Ubuntu 16.04.LTS, x64 (of course), on ""super spiffy"" (that's ""shiny"") hardware and re-created the XP Guest x86. Things ran OK for a while and then began crashing.

I had been thinking about moving the ""content"" (applications) to a virtual Windows 7 box instead anyway, so I created a new Windows 7 x86 Guest. Again, everything ran fine for a while, and then would all of a sudden crash, or not boot, or freeze.

After having pulled my hair out for a few days, I tried uninstalling the VirtualBox GuestOS Additions. First from the XP Guest, and when that got a lot more stable, I did the same thing for the Windoes 7 Guest.

No more crashes, no more sudden freezing, no more BSOD.
(Or at least not yet, two days and counting.)

Every once in a while though, Ubuntu will report a ""System Problem"" and the VirtualBox Guest Window disappeares. In the Ubuntu crash log it says ""This is not an official version ..."" (I'm assuming they're talking about VirtualBox since the 16.04 dist contains 5.0.x). When that happens, however, I am still connected via RDP to the actual Guest OS, and it continues to run."	joho68

No luck, nevertheless. The thread is https://forums.virtualbox.org/viewtopic.php?f=2&t=84071&p=399327#p399327

My host is a 8GB Ubuntu 16.04 running VirtualBox 5.1.26. I have been running a Windows XP guest without problem for the last eight years.

I upgraded my host OS and I don't want to dual boot anymore (Ubuntu/Windows 7), so I copied the relevant harddisks partitions to a VDI image. After messing around a bit with ""fdisk"" and ""grub"", I am successfully booting Windows 7 as a guest. Slow running but Nice!. It is a Windows 7 x86-64 guest.

I proceed to uninstall most HP, Adobe, etc, crap, even the ATI video driver, the WIFI driver, etc. I reboot Windows 7 guest and everything works fine except sound (disabled) and network (drivers uninstalled). I insist that windows works fine, although harddisk performance is not stellar. I disabled Security Esencials and Windows Defender too.

After rebooting one more time, I install ""VirtualBox Guest Additions"" . Install finishes correctly and prompts to reboot. I reboot... and Windows 7 guest is working fine but... with no ""VirtualBox Guest Additions"", Nothing seems to happen. Host integration is not working and VirtualBox says that there are not guest additions running in the guest. I repeat install (it goes fine) and reboot. Same thing.

Checking the guest harddisk, I see ""VirtualBox Guest Additions"" directory with 19 files inside the ""C:/Program files"" directory. Everything seems ok. But the virtual machine is not enabling the Guest Additions.

I wonder if this is a Windows 7 32/64 issue but I lack the knowledge to debug this issue myself.

Please, Help!

Thanks in advance!."	jceajcea

15905	Running Windows 10 as a guest in Xubuntu 16.04.1 host freezes the machine (3D-related)	Linux	VirtualBox 5.1.4	2016-09-08T08:24:46Z	2017-08-17T15:12:28Z	2017-08-17T15:12:28Z	"While attempting to boot a Windows 10 guest on Xubuntu 16.04.1 host, as soon as the Windows logo and the dots running in a circle appear, the whole system hangs. Nothing can be done except pressing the physical power button to shut down the machine.

At first I thought this is related to https://www.virtualbox.org/ticket/13795, but that ticket tells the problem has been fixed already for 5.0.2 and my version is 5.1.4 directly from vbox repository.

I found somewhere that adding `nosmap` to kernel parameters would work, and once I managed to boot the guest system up. Today it didn't help.

I'm attaching the VBox.log, hopefully it helps. In it you will see that guest additions are from an older version. The guest OS was used in an older version (Ubuntu repository version 5.0.24-dfsg-0ubuntu1.16.04.1), but it shouldn't affect this as during the aforementioned time I managed to run the system, it informed me about this but didn't prevent the usage at all.

16958	Guest display auto-resize dit not work anymore	Linux	VirtualBox 5.1.26	2017-07-29T15:41:06Z	2017-07-29T15:41:06Z	2017-07-29T15:41:06Z	"Guest display auto-resize worked perfectly for years (Windows 10 guest on Kubuntu 14.04 host). Since upgrade to VirtualBox 5.1.26 r117224 (from 5.1.24 r117012), the display resolution is not evaluated properly.

At startup the VM display resolution is wrong in fullscreen mode (1920x1080 instead of 1340x1440 on the host). There is no way to set it manually in Windows display properties settings. The maximum proposed resolution is 1920x1080. The host resolution (1340x1440) is not present in the proposed list.

The following workaround works:

* Disable ""Auto-resize Guest Display""
* Enable it again immediately (without any screen mode change before)

Then the guest window is set to the proper resolution (and this resolution become available in the Windows display settings).

'''Remark:''' there is another bug. Just after the VM startup (in fullscreen mode), this workaround cannot be applied directly. In the mini bar, the ""Auto-resize Guest Display"" option is not clickable (like if it was disabled). Pressing <host>-F  (to exit fullscreen mode) then  pressing <host>-F one time again (to get back in fullscreen mode) fixes it. The ""Auto-resize Guest Display"" option become operable.

The effect of the workaround is very volatile. If, for any reason, the guest display resolution is reevaluated, then the correct resolution is lost. For example, in all the following situations (but not limited to), the correct resolution is lost and the workaround has to be applied again to recover the correct screen resolution:

* The VM state is saved and the restored later
* The VM window is minimized and then restored on the host.
* The guest screen mode is changed (any mode), then restored to fullscreen.
* ...

Apparently, any action that conduct to reevaluate the guest display resolution bring back a wrong one (except if you are lucky and have a 1920x1080 display). The workaround must be applied again to get back to the correct screen resolution.

  I have openSuSE x86_64 host and Win7 32-bit guest. I experience regular lockups (guest and host) when using WDDM and Aero on Win7. The strange part is when the Win7 crashes or locks up, it will also lock the host desktop (kde3, i3 or fluxbox). I know that WDDM is experimental, but given then number of ""Hey, I'm using it and it works great"" howtos and tutorials, I would expect it to be a bit more reliable than I am seeing.

  I have the virtualbox.org rpms and extension packs installed, along with the guest additions, e.g.:

Oracle_VM_VirtualBox_Extension_Pack-5.1.18.vbox-extpack
VirtualBox-5.1-5.1.18_114002_openSUSE132-1.x86_64.rpm
VBoxGuestAdditions_5.1.18.iso

  I am running the guest on hp_8670W laptop, i7, quad core, hardware virtualization, 8G of ram. Guest is allocated 1 CPU, 2560M Ram, 256M Ram to display with 3D and 2D video acceleration checked.

  The lockups are semi random. Enabling Aero works fine. The desktop looks great, but anywhere from 30 seconds to 5 minutes later, all CPU/Network/etc. indicators in the status bar go red and the guest is locked. The mouse and keyboard are also trapped in the guest and the host desktop is locked (well, left without any input devices) as well.

  When I reinstall the guest additions, removing WDDM, and drop back to the basic Win7 Pro desktop, all is fine. I can run all day/night without issue. (64M Ram for display, 2D acceleration, no 3D.)

  I'm not sure where the bug is, but I would sure like to help get it fixed."	drankinatty

Setup and process of snapshotting and snapshot removal:

I have a situation where I need to run a long set of analytics in a guest VM.  I constructed a single base VM that installed all the software and base set of data.  I then created 4 linked clones of that base VM.  In each clone, I then configure the specific parameters of an algorithm.  The execution of each set of analysis is approximately 1 month.

To protect myself from unexpected problems that require a complete restart of the analysis, I began to use snapshots twice a day to capture the current state so if the VM crashed for any reason (e.g. power outage or the host becoming frozen), I have a state that I can revert to and resume, losing at most 12 hours of analysis.

After a couple of days, I decided to clean up a few of the older snapshots (using the UI to remove old snapshots in the order of oldest to newest until I had only one snapshot left and the current state for each clone).

I performed the snapshot operation one each of the running clones and I conducted the snapshot removal against the running clones.  In other words, as the VM was running, I began with the oldest snapshot and used the GUI to do the removal (merge and delete).  All worked well.  The VM continued to run and I was able to take another snapshot and then remove the older snapshot.  However, when I decided to do maintenance to the host, the problem emerged.  

I saved the state of each running clone, conducted my host maintenance (basic patching and rebooted the host).  When I went to restart the 4 clones, each reports that there is a missing snapshot.  The snapshot is the immediate parent which is the snapshot just prior to the current snapshot.  Error message below.

The missing snapshot that it cannot find I believe to be the most recently removed snapshot from the running VM prior to saving the state.

I've attached 2 views from the Virtual Media Manager.  View 1 shows the child of Clone1 which represents the current state (I believe).  It also shows its parent ""missing"".  View 2 is the same but I highlighted the ""missing"" snapshot.

The third attachment is from the VBox Manager showing the snapshots for Clone1.

Doing a showmediuminfo command against the lowest level snapshot (current state), it shows that the Parent UUID as the missing snapshot (which was deleted via the GUI after it merged it with the base).

I haven't found the way to change the uuid that shows up in showmediuminfo to match the uuidParent of the dumphdinfo.  I believe this would resolve my problem and allow me to restore the saved state of my clones.

My snapshot directory also interestingly has multiple saved state files which I assume happens as part of the snapshotting of a running VM since the date and time stamp corresponds to the snapshotting events.  So, these do not look to be cleaned up by the snapshot process.

My current option is to revert to the snapshot, discarding the current state and reprocess the work from the last 12 hours.  I'll save clone1 as is incase you need more information.

So I press the host key, right ctrl, to disable integration, and that kinda works, but only for a brief moment. Meaning:

- I press host key, icon goes from green to black.
- I can wait forever and nothing happens (ok)
- I press volume up or down, volume is changed in the host
- After about 1/2 sec the icon goes back to green and integration is active, hotkeys don't work anymore in the host.

Even more strange is the behaviour with brightness control:

- I press host key, icon goes from green to black.
- I press dimming up or down ONCE, host screen is affected
- I can wait whatever time I want
- I press dimming up or down again, host screen is affected again
- After about 1/2 sec the icon goes back to green and integration is active, hotkeys don't work anymore.

Maybe it has something to do with windows focus because these hotkeys trigger on screen notifications, but the integration is reactivated well before the notification is gone, and for brightness it only happens on the second event, so the first notification does nothing.

Instead, I have to copy the folders locally in order to operate on them.

I have seen other reports similar to this with Windows host and Linux or Solaris guest that can be resolved by specifying permissions at the time of mounting, but I don't see any options like this for attaching a Windows share.

This is easily repeatable and was not the case when running Windows XP (32 bit) as a guest OS on Ubuntu 10.04 (64 bit host OS).

These machines are running recently patched versions of Red Hat Enterprise Linux Server release 6.6 (Santiago). The problem has been seen on about 6 different machines. This is occuring with VirtualBox 4.3.26 but has been happening with many other recent releases in the 4.3 series. We only have 1 guest VM running on each of these RHEL machines and it is running Windows 2008 R2 64 Bit as a guest.

We have not as far as we know configured the HP Watchdog Timer in any special way.

I'm not sure if the issues are caused by Windows (at least a clean reinstall did not solve them) or VirtualBox but to go sure I have created this ticket. In the attachments is the VBox.log of a session where both issues got reproduced. Also there is a testcase for the lockup issue (testcase.css and testcase.html) which needs to be put into a shared folder and testcase.html needs then to be opened with any browser (for example Google Chrome). Keeping F5 pressed to cause Chrome to reload the testcase multiple times should cause the race condition to appear after a few seconds (noticeable by not seeing the green circle on Virtual Box's shared folder symbol anymore and Chrome trying to load the site for an infinite amount of time)."

To reproduce:

1) have more workspaces active in Gnome, e.g. A and B
2) start restoring a suspended Windows 10 VM in workspace A; the Windows desktop is showed darkened, to represent that you can't use it yet
3) switch to workspace B before restore is completed
4) wait some time for restoring to complete
5) switch back to workspace A

... and the Windows desktop will still be darkened, despite being active. 

If, instead, you don't switch workspace for the duration of the restore, the darkening is removed at completion.

Note that if - from another workspace - I ""look"" at the VirtualBox window using a video capture device (e.g. obs-studio), the window is correctly not darkened.

The issue could be VirtualBox's or of the way VirtualBox interacts with Gnome's window manager / composite manager (mutter?). I found a similar issue from the past at https://forums.virtualbox.org/viewtopic.php?f=7&t=68896&p=372386#p328269 , with compton, another Linux composite manager.

I have a GTX 1070 running my arch linux host displays.  I would like to use PCI passthrough to attach the intel graphics to the win7 guest.  So I ran the modifyvm --pciattach command with no errors and booted up the guest.  Windows detected the new hardware and downloaded and installed the HD 530 driver.  In device manager, it says the device could not start because there are not enough resources. So I tried disabling the virtualbox display adapter and rebooting.  However when I rebooted, it hard locked my host.  I could not even use the magic sysrq shortcuts to reboot.  I tried two more times shutting down and rebooting the guest, but it hard locks the host every time. I wanted to do further testing to try to get the guest to enable and use the HD 530 card, but I don't want to risk losing data from the hard lockups, so I have stopped testing and detached the device.	walmartshopper12
12495	Sampling profiling method not usable in Visual Studio 2013	Linux	VirtualBox 4.3.4	2013-12-16T16:59:36Z	2016-10-30T10:56:59Z	2016-10-30T10:56:59Z	"Windows 7 Enterprise SP1 x86 guest (VM from Microsoft's http://modern.ie/ site), Lubuntu 11.10 x86-64 host. Laptop CPU Intel Core 2 Duo T8100. VM is set to use one CPU core.

I installed Visual Studio 2013 and am trying to use its profiling feature. However the ""sampling"" mode doesn't work. I can launch the executable to be profiled, but on exiting it Visual Studio reports that no samples were captured.

This bug report is to suggest that support for whichever CPU performance counters or timer hardware that Visual Studio profiling uses, be added to VirtualBox.

I found an MSDN blog post about profiliing in virtual environments:
http://blogs.msdn.com/b/mgoldin/archive/2010/01/09/visual-studio-profiler-in-virtual-environment.aspx
That mentions VS 2010, so I assume VS 2012 and VS 2013 have the same issue. According to that post, Visual Studio has specific support for VMWare, Virtual PC and Hyper-V VMs.
""Visual Studio profiler usage on virtual machines was limited so far, as it didn’t support Sampling mode in such environment. I’m glad to note that in Visual Studio 2010 you can sample your applications inside of virtual machines. VMs could be created using either VPC, VMWare of Hyper-V technologies. 
Some hardware is not virtualized, though, and CPU performance counters (that are used by profiler) are, unfortunately, in the list. To overcome the issue, we used a different approach that targets each VM-vendor specifically, and timers that are used in virtual world are not the same as on a raw hardware. Some functionality, however, suffers from lack of CPU performance counters virtualization.""

Also a comment at
   http://serverfault.com/questions/194585/visual-studio-profiler-in-virtual-machine 
mentions that profiling uses the Local APIC timer.

When I want to stop playing, the moving cursor, which shows which note is being played at the moment, stops immediately but the sound actually stops after 2 seconds. 

This lag is presented everywhere - for example start a browser and watch video on YouTube - sound and picture walk past each other and the synchronization is lost.

This happens on Arch Linux host and Windows XP, Windows 7 and Windows 10 guests. There is no difference between the different guests. All of the guests have the latest Virualbox Guest Additions 5.1.6 installed.

15804	5.1x Windows Guest Video Playback 2x speed - No Sound	Linux	VirtualBox 5.1.4	2016-08-17T08:13:37Z	2016-10-12T03:02:56Z	2016-10-12T03:02:56Z	"Problem: 
With 5.1x if I play back a video in Windows 7 guest then it does not have sound and the video plays back at about 2x speed. This is true in several media players. Also, true in Firefox 47, 48 and Google Chrome 52. So this issue is systemic. Tried disabling 2D and 3D with the same issue. Went through several installs, cold power downs, reboots and many experiments.

Solution:
Uninstall / Purge VirtualBox 5.1x and install 5.0x (5.0.24) and video playback and sound work properly.

Win10 x64 acceleration has never worked for me, since even before 5.x came out. The boot splash screen works correctly, but when the login screen is supposed to appear, instead I see the cursor cycle endlessly between pointer -> busy -> background busy over a black screen; the login screen never appears.
My guest is entirely up to date and has Oracle (i.e. not Ubuntu) additions 5.0.14 installed; other additions functionality seems to work fine (including guest display resizing if acceleration is disabled).

Also, there is another problem which might be unrelated but flash videos on different sites hang while loading inside VM. Sometimes they even become slow.However, they instantly open on browsers outside the VM. In the 5.0 series I used to face flash videos becoming *slow* during playback(like 1 second on the flash video elapsing after 3 seconds in real). I didnt report it because a restart would fix the problem for many hours till it recurred. This problem seems to have been cured in 5.1 though.

15935	VirtualBox breaking Unity's Compiz Scale Plugin	Linux	VirtualBox 5.1.6	2016-09-15T15:09:13Z	2016-09-15T15:09:13Z	2016-09-15T15:09:13Z	"My setup: Ubuntu 16.04 host, Win8 64bit guest.

On the host when I enable the Compiz Scale plugin in CompizConfig Settings Manager and give it a window binding (say the top of the screen initiates the plugin) everything works except when Virtualbox is the active window. When Virtualbox is the active window it ""steals"" the mouse movement when moving to the top of the screen and leaves the desktop in a bad state. The scale plugin is now broken (it no longer triggers) until I manually switch to a different active application then re-initiate the scale plugin via the mouse at the top of the screen. After that it works fine again until I try to trigger it with VirtualBox being the active window. If, however, I press the host key (right ctrl in my case) before I move the cursor to the top of the screen it initiates the Scale plugin as expected.

On previous versions of VirtualBox this all worked. Not exactly sure what version this started happening in unfortunately.

This is quite hard to explain, but it is 100% reproducible on my machine. I've tried everything from clearing all gnome settings, clearing all compiz settings, etc.

sometimes they menus render on the wrong place on the display (only happens if menu is at the bottom)

sometimes unity (ubuntu's launcher) consumes clicks from the VM

since VirtualBox 5.1. when I switch Ubuntu workspace it instantly switches back to the workspace where the VM is running which is a show stopper for me

If I succeed logging into the client, the keyboard works fine.

The scenario:

I just updated the host from Ubuntu 14.04 to 16.04. 
On 14.04 I never saw this problem.
Maybe I should mention, that I upgraded Virtualbox also from 4.3.x to 5.1.4.

I have some headless Windows guests (Win 7, Win 10) - all of them have the same problem.

When I now try to connect from a Linux machine:

rdesktop -a 24 -g 1600x950 -z -N -xl -u klaus -d gbr 192.168.1.30

I see the welcome (login) screen and I'm able to use the mouse, but I cannot type in a password.

I can workaround this using the -p option:

rdesktop -a 24 -g 1600x950 -z -N -xl -u klaus -d gbr -p - 192.168.1.30

but thus is nasty, as you cannot put such stuff into a menu item (putting the password in plain text would help, but us at least as nasty).

Strange to say, that this phenomenon does *not* occur, when I omit all those user related options (-u, -d, -p). When using this commandline:

rdesktop -a 24 -g 1600x950 -z -N -xl 192.168.1.30

everything is fine. I see the login screen and can type in my credentials.
Unfortunately I have to type in all the stuff now (user, domain, password) each time ... that's annoying, but it works .... as long as noone uses one of the -u, -d, -p options.
If anyone tries to connect using one of these options, the keyboard is dead at the login screen for all subsequent connects. 
I need to poweroff/startup the guest machine to get this working again.

This is reproducable with rdesktop 1.7.1 (e.g. on LinuxMint 17.1) as well as with rdesktop 1.8.3 (e.g. on Ubuntu 16.04). Therefore I'd say this is no rdesktop problem but rather a problem of virtualbox.
I unfortunately haven't found possibilities to debug/trace those connections - that would possibly give us some more informations..."	kläuser

9007	Captured/filtered USB devices are released and reacquired when guest reboots	Linux	VirtualBox 4.0.8	2011-06-01T13:34:26Z	2016-08-23T07:18:59Z	2016-08-23T07:18:59Z	"Hi,

Host: Xubuntu 9.10 x86, VirtualBox 4.0.8 (with PUEL extension pack).
Guest: Windows XP SP3

When the guest is rebooted, VirtualBox seems to free/release any filtered USB devices, then re-capture them. I think all filtered USB devices should remain filtered when the guest reboots.

This problem is most noticeable when using a USB floppy drive. Most(?) Linux distributions treat USB floppy drives as generic removable drives. So when you insert a disk, the kernel attempts to read the last sector and scans for partition tables. In combination with the default block device readahead of 256 blocks, that process can take 30 seconds or so. *Every time you insert a disk*. It's quite annoying. Floppy disks never have a partition table of course so the scan is pointless. Anyway...

To reproduce the problem:
 - Connect a USB floppy drive to your system.
 - Add the floppy drive to the USB Device Filters of a Windows guest VM.
 - Start the Windows VM. Insert a floppy disk. Notice the drive only spins for a short time. Because it is captured, the Linux host OS doesn't attempt to access it.
 - Reboot the guest OS.
 - Notice how when the guest reboots, the kernel creates a /dev/sdX block device and scans for partitions (taking about 30 seconds). Then the block device is removed when VirtualBox re-captures the device.

Other drives are probably affected similarly, so you get an unnecessary block device creation, partition scan and device removal whenever the guest is rebooted. (That takes less time than for USB floppy drives so will be less noticeable.)

When WinUAE is using DirectDraw for its graphics output, dragging the window partly off-screen causes the image to appear near the upper left of the screen. See the attached screenshots. The problem does not happen when WinUAE is set to use Direct3D.

To demonstrate:
- Download an example program, e.g. ftp://ftp.amigascne.org/pub/amiga/Groups/D/DOC/DOC-NoName
- Download the WinUAE installer from http://www.winuae.net/ and run it.
- Run WinUAE. When the setting window opens click Miscellaneous in the treeview. Set Graphics API to DirectDraw.
- Click Floppy drives and then the ""..."" button near the top right of the window. Choose the program you just downloaded.
- Click Start to start the emulation. In a few seconds you should see something in the emulation window.
- Press the middle mouse button to un-capture the mouse and drag the emulation window so it is partly off-screen. Notice that the window contents appear at the top left of the desktop, and the actual emulation window no longer updates.

Since then, host was wiped and Debian 7 was installed with latest !VirtualBox 4.3.26. A crash occurred again recently and so I started investigating.

Crashes seem random. Windows VM was the only VM on the host at the time of the second crash, it was just applying Windows updates. Reverting to a previous copy of VM and reapplying the same Windows updates again did not cause the crash again. Nothing appears in the logs at the time of a crash (both Linux and !VirtualBox logs).

However, when I connect directly to the VM using RDP (port 3389) and set the audio to ""Local"", I get it loud and clear.

To be sure that this is not a VRDP artifact, I cloned the VM and ran it on a VirtualBox instance on a Windows Host. On Windows, I am ale to access the sound both ways.

There is a wontfix (https://www.virtualbox.org/ticket/10923). However, I think that the issues are slightly different. This case is specifically about a different way in which the VRDP has been implemented in Windows and Linux.

15394	GetLogicalProcessorInformationEx() broken under Windows 7	Linux	VirtualBox 4.3.36	2016-05-07T08:39:16Z	2016-05-07T08:39:16Z	2016-05-07T08:39:16Z	"Hi.

So, the main issue I want to report is that GetLogicalProcessorInformationEx() basically returns garbage under Windows 7.  It's a fresh, Vanilla install of Windows 7.  The only software installed is the Windows Platform SDK.  The first record returned looks okay, but they rapidly deteriorate until after two or three you're looking at 0xCDCDCDCDCD, etc.

GetLogicalProcessorInformation(), the earlier version (no ""Ex"" on the end), also has a problem, but it seems mainly to work - the problem is that it only reports data caches.  No instruction or unified caches are reported.  Everything else seemed fine, on my one system.

Separately from VB, but related to getting this bug reported, the Oracle account creation process appears to have a number of issues.

1. The account creation page does not load if DOM storage is turned off.
2. Upon creating the account, a page is shown saying an email has been sent with instructions to activate the account.  In fact, a password reset email has been sent.
3. Upon performing the password reset, a SECOND password reset email is sent.
4. Upon performing the second reset, the account is confirmed.
5. Trying to log in does not work, at least not under Firefox - ""page is not redirectly correctly"".  However, you are in fact logged in, and so I was able to come back to this page and post this bug report.

As an aside, I spent three hours this morning trying to get VB 5.0 installed, to see if the GetLogicalProcessorInformationEx() existed there.  I was able to install 5.0 itself just fine from the VB repos, but the QT interface is not provided.  After a few hours, I concluded that although the QT package is shown via the web by Debian to be present in jessie-backports, it in fact is not present (not indeed are any of the 5.0 packages); aptitude only finds 4.3.36.  I gave up.

Then I started wireshark on hosting machine and I tested the issue also with netcat: sending simple echo from the virtual machine results to double response received by netcat in my laptop. The wireshark clearly shows that the virtual machine sends back duplicate packets for ICMP, UDP and (testing with SNMP traps) also for TCP protocols.

My host is a NAS-like CentOS 6 box with no attached monitor, no X server and no sound card. On it I spawn a bunch of lightweight bridged Windows machines for browser testing and connect to them from my desktop PC running Windows (gigabit LAN between the client and server).

This setup worked flawlessly with Virtualbox 4.3 and Windows 8.1. I've stopped using the VMs for a while and recently ressurected them with the following changes:

* Updated to Virtualbox 5
* Switched desktop to Windows 10

Since I did that, I'm getting choppy high pitched audio when connecting to the VMs (both before and after installing guest additions). The emulated chipset is Intel HDA and the driver is obviously Null as the host doesn't have a sound card. I originally thought this was an emulation issue, however:

* after doing some research about other issues about windows 10 clients being unable to connect in previous versions
* and reading on some other oracle website that VRDP only supports 22050 audio (not explicitly related to vbox, but pretty sure the V stands for the same thing),

I believe the issue is strictly related to the changes in the Windows 10 RDP client because:

1. playing back a realtime 22050hz stream on a 44100 output device would explain both symptoms (high pitch caused by the freq mismatch and choppiness caused by buffer underrun)
2. setting up a windows RDP server on a guest (tested on a win10 guest) and connecting to that works flawlessly

Unfortunately, I don't have a Windows 7 box to test this on, but I'm going to try some RDP-ception later today.

The guest has the new (5.0.16) Guest Additions, which was installed using Windows Safe Mode (so I could install basic 3D acceleration as well).

If I open a random text file of 12582911 bytes (eg. in Notepad) in the guest OS, select it's entire contents and copy it to the (shared) clipboard, then I can paste this into gedit in the host OS.

If I add a single character to the end of the file (so it becomes 12582912 bytes long) and do the same, I cannot paste the clipboards contents into eg. gedit in the host OS.

And of course: anything below 12582911 bytes works too and anything above 12582912 bytes doesn't work. :-)

I tried various apps in the guest (Notepad, Wordpad, Notepad++, Total Commander) to open the text file and copy it's contents to the shared clipboard. And I tried various apps in the host OS too to paste the contents of the clipboard. All showed the same symptom.

I created the test text file in linux using this command (I used unix2dos to convert the text file to DOS/Windows line endings so eg. Notepad won't die on me):
{{{
dd if=/dev/urandom bs=12M count=1 | base64 - | unix2dos | dd bs=1 count=12582911 of=test.txt
}}}

It's contents can still be transferred from guest to host via shared clipboard, but if you add only a single extra character to it, the clipboard transfer fails.

Nothing appears in VB's log or in the host's logs (eg. syslog). Neither when the clipboard transfer works, nor when it doesn't.

In the VM I've ""Shared Clipboard"" set to ""bidirectional""."	muzso

Additionally to this issue that I'm seeing content of the graphics card instead of the document this behavior could leak unwanted data to the guest system.

13494	Overloaded message loop makes Guest window unresponsive to inputs when guest additions installed	Linux	VirtualBox 4.3.16	2014-10-11T11:20:45Z	2015-10-17T20:33:36Z	2015-10-17T20:33:36Z	"I'm on Ubuntu 12.04 host using LXDE desktop, and the guest is Windows XP. I haven't tested it with other Windows versions like win7. 

My old GDI+ game completely freezes the guest window after some seconds. The only the to recover is simply killing the virtualbox process. It doesn't happen when guest additions are not installed.

I decided to investigate further and wrote the C program that reproduces the problem. (Simply using the Code::Blocks template with some edits).

The normal behavior is when you see the repeated rederawings clicking on the window should immediately bring up a messagebox with the coordinates. Or pressing key should bring up one with the character pressed. '''This happens on native windows, and in VirtualBox without guest additions'''. 

With guest additions, if you run it for some time and click the window, nothing happens. The drawings keep going and you get response after several seconds. 

It looks like the driver becomes overloaded with stuff, rendering the window unresponsive, till it processed all the events.

It's probably worth noting that the hard disk indicator is red when this hanging happen. Maybe it's writing somehing? I'm not sure whether the VM is thrashing or just because the whole GUI was frozen.

Adding several milliseconds of Sleep() into the message loop relieves the problem a bit. But it makes the game very laggy. 

Hopefully this helps reproducing the problem.

Also a note: at least one OpenGL game the OpenArena works fine on VirtualBox too.

Receive the following error:  ""The document cannot be saved, as it was not possible to write to /media/sf_Shared/lin.txt.  Check that you have write access to this file or that enough disk space is available.""  In Linux guest delete file works.  With a Windows 8.1 Guest VM access shared folder via G: drive (\\vboxsvr\Shared).  Can create file, however cannot modify file lin.txt.  Receive error:  ""An unexpected error occurred while writing G:\lin.txt.""  In Windows guest delete file works.  Also,  created file from both Linux and Windows guest systems and then accessed the file from the host.  Confirmed permissions set on the file were correct.  Can modify the file via the host.

Temporary Workaround:  In both Linux and Windows guest systems connect to SMB server directly (\\mestor\Shared).  Can modify files.

7405	When RDP to VM is terminated badly - VM still holds RDP session open	Linux	VirtualBox 3.2.8	2010-08-31T18:38:34Z	2015-08-13T17:32:44Z	2015-08-13T17:32:44Z	"Now my Vista machine is a piece on junk and likes to lock up. So it needs cold rebooting. The problem is that the vrdp tcp connection stays established on the Linux machine even after rebooting the vista machine. So I cannot reconnect back to my running VM and also have not been able to force it to disconnect. I've tried below with no success.
{{{
VBoxMange controlvm winxp_work vrdp  off
VBoxMange controlvm winxp_work vrdp  on
}}}

I see from netstat that the VM still thinks there is a RDP session established. Even when the keepalive timer times out - it just resets rather then closing the connection. Occasionally if I wait long enough - I can reconnect - but we are talking 15min plus.


Some details:
 1. Virtual Box installed (3.2.8r64453) on 64bit Linux host (amd64 all distro version).
 2. Win XP 32 bit guest installed with latest Virtual Box tools.
 3. VM started with ""VBoxHeadless -s winxp_work &""
 4. VBoxHeadless disown'ed from bash to stop it killing it if I close shell
 5. Access VM from Vista 64 via remote desktop
 6. Linux iceweasel 2.6.30.4-2 !#7 SMP Tue Aug 11 17:12:39 MDT 2009 x86_64 x86_64 x86_64 GNU/Linux
 7. Using a bridged interface

Does anyone have any ideas how I can convince the VM that the RDP session is over - or maybe I need to change some global tcp settings somewhere?

Machine: Thinkpad Yoga laptop with I7-4600U processor and Intel HD Graphics 4400.

Host: Debian 8.0 AMD64 latest (XFCE4 window manager, though should have no effect)

Guest: Windows 8.1 64bit pro , with 2D and 3D acceleration enabled in VirtualBox.

VirtualBox: 5.0

Installed the ""guest additions"" in the guest.

Problem description:


(A)

Playing any YouTube video (e.g. https://www.youtube.com/watch?v=1Y0kX7dfGKU ), in any resolution (even 144px!),

 * lags so bad that viewing is unbearable,

 * very clear vertical sync problem (i.e. half new frame on upper part of screen, half old frame on lower part of screen), and

 * the audio output is stuttering (indicating CPU overuse).

So it looks like video presentation is unaccelerated!


(B)
Installing VLC player and making it use the ""Direct2D video output"" rendering backend, produces *excellent* video playback though!

If I only knew how to switch the web browsers into this video output mode!

(There is a slight vertical sync but that's fine.)


(B.2)
In VLC, using the ""DirectX"" backend shows a black window though!

(B.3)
In VLC, using the ""Direct3D"" or ""OpenGL"" backend crashes VLC though - it just exits and there's no crash report dialog box or alike!

(B.4)
In VLC, using the ""Windows GDI"" backend produces the same video display experience as in (A), i.e. stuttering video and audio - this indicates that (A) is made completely without acceleration?

(B.5)
In VLC, using the ""OpenGL (experimental)"" backend gives no output.

(C)
The video in (A) was HTML5 video playback. Also trying Flash video playback on http://www.adobe.com/devnet/flash/articles/vidtemplate-engage-with-flash.html gives some kind of stuttering in the video and audio playback, while not nearly as bad as in (A), it's still very laggy.

PROBLEM:
When switching to full screen mode, the VM screen resizes all right to fill the screen,
but the screen is dimmed (brightess is reduced). Looks similar to the effect when you
pause the VM, but not quite.

INVESTIGATION:
I narrowed down the problem to compton, a compositor for X11.
When compton is killed, the fullscreen mode works fine.

Previously, with VirtualBox 4.3.30 (and many versions before that), fullscreen mode used to work
correctly with compton."	coriolan
14222	VM window should not be brought to front when it becomes active in full-screen mode	Linux	VirtualBox 4.3.28	2015-06-25T19:43:32Z	2015-06-25T19:43:32Z	2015-06-25T19:43:32Z	"Using VirtualBox 4.3.28 on Lubuntu 14.10 x86-64 host.

I have the window manager (Openbox) configured so the window under the mouse pointer is automatically activated, but not brought to the front, when the pointer moves over it. (Clicking in a window does bring it to the front.)

That works fine with a VirtualBox VM which isn't in full-screen mode. However when a VM is in full-screen mode, the VM window is brought to the front as soon as it becomes active, even though it has not been clicked in.

That's quite annoying if I have Alt-Tabbed out of the VM and am using other programs, with the VM window appearing behind the other program windows. As I move the mouse pointer from one other program window to another, as it passes over part of the VM window, the VM window is brought to the front, obscuring the other program windows.

I think a better behaviour would be to only bring the VM window to the front when the user clicks in it."	Donuts

A laptop (15"" 1600x900) with a large monitor (24"" 1920x1200) as secondary monitor. I would run a Win guest on the large, secondary screen in seamless mode, so my Cinnamon taskbars & menus are on my laptop screen, my Win7 bar is on the bottom of my 2nd monitor.

As of 4.3.18 the seamless mode mimics the height of the primary monitor (900px) though taking the whole width. Fullscreen mode still works as expected and takes up the whole secondary screen. 

More oddly, in seamless mode the 900px frame is positioned somewhere in the middle of the screen giving my a flying taskbar and VBox Toolbar.

I always faced a problem that the VBox Toolbar menues appears with a vertical offset to the actual toolbar hover (something like 300px below). But I think this is rather a Gtk issue which I can tackle.

A popup then appears prompting me to do `sudo /etc/init.d/vboxdrv setup`

If VirtualBox knows that this is needed, why doesn't it just do it itself? Maybe just showing a prompt with a more user-friendly message saying 'VirtualBox needs to recompile its kernel modules, probably due to a recent OS system update. Confirm?' and the user just presses OK and its done automatically?

At the moment this process is really annoying:
1. You have to copy the command to run from the message box.
2. You have to open a terminal window and paste it but NOT press enter, since Virtual Box is still running. If on the other hand you close Virtual Box before pasting the clipboard info is lost.
3. Close VirtualBox
4. Press enter, wait for Kernel module recompilation.
5. Start VirtualBox.

This could immensely be simplified from a user point of view if when the message is shown and the user confirms, VirtualBox automatically closes, recompiles the kernel modules and restarts.

DO : start a Civ IV game
EXPECT : the map is properly displayed
ACTUAL : rendering is broken (almost everything black). Playing with details does not change anything.

Virtualbox 4.3.26-98988 (happened also with 4.2.28-97679)

I have an XP virtual machine with a test installation of oracle rdbms. To do some speed optimizations on some plsql code and compare results, I cloned it (complete) and changed name, mac and ip.

When one vm is running and idling and I launch the other one, both the machines go to 200% cpu consumption (quad core host). After a (long) while the second machine boot completes, and they both go back to idling.

When I log in on the second vm, the first starts spinning again. After a while the login is completed and both go back to idle.

Whatever I try to do on one of the two, the other one immediately starts using all the available cpu, 50/50 with the first one.

Both the original vm and the clone run perfectly on their own, if the other one is shut down or even paused. If I run another unrelated XP guest with one of the two, the issue does not appear.

I'm using vboxheadless and connecting with Remote Display, but this can be triggered also when not connected to the desktop, e.g. launching a plsql cpu consuming loop via sqldeveloper (not i/o bound operations).

I initially installed the VirtualBox-4.3.20-96997-Win in January this year. It was working fine for about a month, the period I was using it.

However, today, after a gap of about 2 months when I again wanted to use it, it refused to open and flashed the error message mentioned below. I read somewhere that reinstalling helps in solving this problem and so I did exactly that by first using the same version and when that didn't work I downloaded the recent version (VirtualBox-4.3.26-98988-Win) and installed it. However it too is displaying the same message now.

Can someone help me in solving this problem?

Attached is the latest log from the last time I reproduced the bug, these are also the events I describe in this report. 

1. Start guest VM.
2. Open notepad or any input field to test keyboard
3. Type some words. 
4. Press right Ctrl to release keyboard from guest
5. Press alt+tab to switch host OS program, do not release alt
6. Switch back to guest VM with alt+shift+tab
7. Type some words in notepad

Expected result:
Letters from a-z and numbers from 0-9 typed out on screen. 

Result:
The menus activate randomly in notepad, no words are typed. In other programs like Putty I see strange characters being input, sometimes spaces, sometimes returns, never the expected character. In the Windows desktop random functions might be activated, or nothing will happen at all depending on what keys I press from a-z and 0-9 on the keyboard. 

Workaround:
Press left ctrl+alt once and typing is restored. "	stemid

This software (Magpie from MEA in Australia) extracts certain data from certain binary files output from a datalogger and collates it in a database. When run in WinXP under VirtualBox with the data stored in a VirtualBox 'shared folder' mounted as a Windows network drive it loses data.  When the data is stored within the VirtualBox 'disk' it works fine and it also works fine when the data is on a real Windows network share.

I have spoken to the developer of the software and it turns out that it is using the Windows API calls 'FindFirstFile' and 'FindNextFile'. The virtualbox ""pseudo-network redirector"" driver in WinXP is not returning files in the same order as either windows or a windows network share (which it is pretending to be) does. This leads to the data problems within the software. See attached screenshot for file dialog box with incorrectly ordered files. When the data are stored on the windows virtual disk or on a windows share the files are in date order.

Interestingly, when run under WINE the file order in this dialog is exactly the same as when run using Virtualbox and a 'shared folder'. I conclude from this that when the above API calls are run against a virtualbox 'shared folder' it is presenting the files as they are presented to it by my linux host, not in the order that windows would present them.

Unfortunately, I am not a developer and have no idea how linux chooses to present it's files or anything further about these API calls..."	solanum

Correct behavior is that as mouse is over a node tool should change from pick to node edit however with additions 4.1.0 this is erratic and often never happens at all.  Other less consistent problems are also occurring, for example on complex graphics it is sometimes impossible to select an object.  Again this problem only manifests when additions 4.1.0 are installed on the guest.

I have tried disabling both 2d and 3d acceleration but this did not resolve the problem.  I expect this bug will cause problems in other applications too where manipulation of graphics is needed.

The host has a single display (1280x1024), PS/2 mouse, window manager is fvwm2. Everything was fine about 3 months ago (IIRC that was with VBox 4.0.4).

Started Windows XP today, and as soon as I hit the left mouse button for the first time, the mouse goes nuts. On each click, the mouse pointer is relocated on the screen (makes double-clicks impossible). Mouse movements do not properly end on the edge of the screen but just in the middle of the movement the guest mouse pointer is relocated and mouse control is back under Linux control (a little bit like the Host Key has been pressed during the movement; changing it doesn't help).

Guest additions are not installed (so there's no special mouse integration). It's a standard setup.

I've also moved the old installation out of the way, removed the VirtualBox package, reinstalled it and made a Windows XP (SP2) install from scratch. Same behaviour.

It doesn't look like this is Windows' fault, because it happens with a clean Windows XP SP2 as well as a fully patched and customized Windows XP SP3. Looks like VirtualBox and Linux (Fedora) no longer work well with each other. Fedora is fully patched.

I've also tried a USB mouse (just in case VirtualBox has problems with PS/2), but that didn't change anything. It doesn't look like a hardware fault because everything is recognized and basically works.

Same problem with different screen resolutions within the guest system.

I'm wondering that simple mouse movement can cause the mouse to be no longer captered by the guest system. That should be impossible without the Guest Additions.

I'll append a VBox.log but there are not errors in it.

I have two desktop Ubuntu Lucid machines, let's call them D1 and D2, and two users working on them, U1 on D1 and U2 on D2. U1 has VirtualBox running a Windows VM (V1) with D1 as a host. User U2 has a RDP connection opened to V1. 

The users U1 and U2, however, have different TS sessions on the Windows machine. So U1 sees his Windows desktop in the VirtualBox window on his desktop D1, and U2 sees his Windows desktop in the rdesktop window on his desktop D2. The Windows VM runs two user sessions concurrently.

Every once in a while, when U2 copies something in the clipboard on his desktop session on D2, user U1 is able to paste the same thing on his desktop session on D1.

I believe the reason for this is because there is clipboard sharing between D1 and V1 via VirtualBox, and also between V1 and D2 via RDP. So in fact, the clipboard somehow becomes shared by all 3 machines.

This does not seem to occur when running the VM in headless mode, and both users connecting to it via RDP, which indicates that the problem is more likely in the way VirtualBox manages clipboard sharing rather than rdesktop / RDP.

Host system is dual-head (two 1680x1050 LCD panels), Compiz disabled (by selecting ""None"" for Visual Effects in the Appearance Preferences panel).

VBox is configured for 2 virtual monitors. Windows reports 2 monitors as it should, and is configured to extend desktop onto the second monitor.

I normally run this VM in seamless mode. Works well most of the time. Sometimes when I move or minimize a guest window, there is a rectangular area left behind (same size as the moved/minimized guest window) showing the guest's desktop background. This area will cover up host windows if the guest window was on top of them.

This does not happen all the time. Seems to happen more often on second monitor, but does happen on first monitor sometimes.

In order to recover, I usually have to switch out of seamless mode and back in. Sometimes moving around other guest windows or clicking in another guest window will fix it.

7727	Keyboard should be released to host when mouse moves outside of Vbox window	Linux	VirtualBox 3.2.10	2010-11-16T16:05:37Z	2010-11-17T08:50:27Z	2010-11-17T08:50:27Z	"Currently, it takes two user actions to release the keyboard:
  a) move mouse off the vbox window
  b) click the mouse

The mouse click is unnecessary and redundant.  Moving the mouse is a clear indication that the user wants to do something outside of the vbox guest.  Guest additions should release the keyboard to the host at this point.  Curiously, even seamless mode does not help in this respect.

This may sound trivial at first glance, but it makes things clumsy when switching back and forth between guest vbox windows and host windows.  With Vbox, it takes a careful mouse movement to a harmless place, an additional mouse click, before being able to use keyboard CUA.  Also, finding a harmless place for the extra mouse click can be a problem when using a full host taskbar and a maximized vbox guest window.

Instead, it is much easier to just move the mouse to any max position off of the vbox window, and the use keyboard shortcuts to change to a different host desktop.

As a point of reference, a Large Commercial Virtualization package works this way.  It does not require the extra mouse click."	mtnbiker

VBox will now ignore the previously set window size and instead expand the guest VM window to fill the whole screen. In previous versions it would respect the window size set by the user.

Guest 6.1.16 – Windows XP SP3. Virtual Desktop Aspect Ratio 3x2.3 (600x460Pixels).

I am unable to adjust aspect ratio of the Guest display although I could with my previous installation of this edition.
Previously I could make the adjustment using the VIEW tab - VIRTUAL SCREEN 1, and select an aspect ratio. Or simply drag the window out to suit

This does not work with the new installation. I have tried:

VIEW – ADJUST WINDOW SIZE (HOST + A) which is followed below by AUTO-RESIZE GUEST DISPLAY which is greyed out and ticked. Because it is greyed-out I cannot make any alterations – i.e. untick it?

VIEW tab - VIRTUAL SCREEN 1 select an aspect ratio from the list. 800x600 is ticked but I cannot select another ratio even though the list of sizes is not greyed-out?

PREFERENCES – DISPLAY – MAXIMUM GUEST SCREEN SIZE. I can carry out the functions offered by this screen and can, using the HINT function, save a new Width & Height. These dimensions remain on this window but do not alter the virtual desktop aspect ratio?

Have read some of the Forum’s pleas for help regarding screen issues, and as a consequence, have uninstalled and reinstalled Windows XP twice.

I have tried disabling the guest audio (VM setting no audio), and full audio from the VM settings, but this makes no difference. During the boot, the audio for the host disappears. I've booted with the guest extensions installed and uninstalled, both exhibit the same outcome. Host is macOS Catalina (10.15.4), Touch Bar 2018 MacBook Pro.

After the VM is shutdown, the host audio will return, but it has a slight echo at the end of any audio play, just as the audio ends it stutters.

It was first noticed by me in 6.1.2, but may have been earlier and persists in 6.1.6 and 6.0.20.
Hardware diagnostics return no errors on the host.

I have reduced the RAM allocated, from 4G (50%) to 3G and the audio seems to be ok. From a thread in the forums (https://forums.virtualbox.org/viewtopic.php?f=8&t=96902), a new guest (VDI) built from scratch seems to be ok.

The problem is that those two keys are in the opposite positions of the keys on a Windows keyboard.

IOW, from left-to-right on a Windows keyboard is Control/Windows/Alt/Spacebar, while left-to-right on a Mac keyboard is Control/Option/Command/Spacebar.  Thus, for a touch typist, the mapping should be Control to Control, Windows to Option, and Alt to Command.  The current mapping forces us to learn a completely set of keystrokes on the VM than we're used to on a Windows keyboard (which we have to use anytime we're no on the VM).

Please consider providing a configuration setting that would allow the mapping of these two keys to be swapped, that is, for the Mac ""Option"" key to be mapped to Windows, and the Mac ""Command"" key to be mapped to Alt.

Thank you."	Vince Rice

20099	bridged mode not working in VB on macOS Big Sur for VB windows clients	Mac OS X	VirtualBox 6.1.16	2020-12-23T11:01:20Z	2021-02-17T03:59:37Z	2021-02-17T03:59:37Z	"As posted in the VB Forum:
Finally got to the bottom of the issue after finding a few hints, pointers and bits of information at various places.

After the upgrade from Catalina to Big Sur, networking caused several issues in VB windows instances.
I've always used bridged mode with no issues for both wired and wireless connections before the upgrade.

My symptoms , In bridge mode DHCP in windows failed to obtain a valid IP address, starting with duplicate found and quickly followed with a 192.168.1 address that would not give a proper connection , I use 192.168.0 subdomain. Could not get neither the wired nor the wireless connection to work.

When setting NAT mode the VB windows instance, VB would fatally crash the VB windows instance, so not windows but VB crashed.

I concluded that the last issue must have been caused by VB drivers being messed up after the Catalina to Big Sur transition.

I downloaded the 6.1.16 VB version and used the uninstall script ( available in the finder window when opening the vb.dmg file) to remove VB from the mac.
Don't worry it only removes the drivers and VB itself, not any of your configs or VB disks and client images.
Then re-installed VB. This got NAT back working.

Bridged mode still had same issues for windows clients, it has something to do with change in behaviour of how big sure handles MAC addresses by the looks of it.
The fix is that you have to give the network adapter in VB that is mapped on your mac network adapter the same MAC address as the MAC address for the adapter on your MAC.
This is not a good permanent fix as you this prevents you to have more than one VB client run on your MAC as all you would get duplicated MAC addresses on your system. Be aware of that. Also if you use DHCP with preset IP addresses, each VB windows client will get the same IP address."	pbvbox

Today I installed KeyboardStateView.exe on the guest to see what the keyboard state is after a resume, and it seems that the guest wakes up with the left window key depressed. Pressing the left Command key will get it in sync again.

It behaves the same on both my MacBook Pro keyboard and an external Apple USB keyboard, both with Swedish layout.

I have suffered from this for several versions and I can't remember when I first noticed it.

After a reboot of the client the keyboard is not in this weird state, only after a suspend/resume cycle.

After some more experimenting it appears to be caused by pressing the left Command key+Q to suspend the client and quit VBox. The left Command key appears to be mapped as the left Windows key. If I instead use the right Command key+Q, which seems dead in the client, then this does not happen.

Not sure if this is a bug or not"	Tipo

19785	machine is restarted but with the last working snapshoot	Mac OS X	VirtualBox 5.2.42	2020-07-31T06:00:51Z	2020-07-31T06:00:51Z	2020-07-31T06:00:51Z	"Gent.mi,

ho avuto un problema con una macchina virtuale Windows 7 64bit con host Imac, in pratica ha smesso di funzionare non si avviava più l'errore riportava alla disabilitazione della scheda di rete.

Al riavvio la macchina è ripartita ma con l'ultimo snapshoot funzionante del 2016, ho perso 4 anni di lavoro sul desktop, c'è un modo per recuperare i dati.

In attesa di un vostro cortese riscontro saluto cordialmente.

Recently upgraded my Hackintosh from Mojave to Catalina, and now I can’t boot a Windows VM (Linux ones may have problems too but I haven’t tested extensively). Parallels Desktop works fine

When booting the latest live CD downloaded from Microsoft’s website, I first get this error (on a brand new VM):
“File: \windows\System32\drivers\nvraid.sys
Error code: 0xc0000098”
Then I press enter and get this one:
“File: \windows\System32\drivers\iaStorV.sys
Error code: 0xc0000221”

It seems that a few weeks ago when I tried (VirtualBox 6.1.4), it did the same thing with same error codes but with different file names. I attach the screenshots and log file.

Thanks!"	GilDev

Looking forward to your reply, best regards. Giovanni DV

i call import with default settings.
a popup appears declaring that appliance <somename>.ova could not be imported. Error Code  NS_ERROR_INVALID_ARG (0x80070057)

There seems to be a size dependency:
i was able to import one appliance with size 5,62GB, several others larger than 10GB all fail.

There is of course no space problem on the NEW machine, there are more than 500GB free.
FWIW, i detect nothing of interest in the system logs.

19195	"""Scaled Mode"" makes mouse unusable (lag / slow)"	Mac OS X	VirtualBox 6.1.0	2020-01-03T17:39:10Z	2020-01-03T17:39:10Z	2020-01-03T17:39:10Z	"I am trying to install Windows 98 as a guest in MacOS 10.15.2. The screen is HighDPI, so by default I can't see a thing because the 640x480 virtual screen is way to small (ca. 7 x 5.5 cm).
Full screen mode doesn't change anything, the 7x5.5cm window is just in the center of a large black screen.

So I reverted back to Windows 7 and the full-screen was no longer working.  I tried to uninstall and reinstall the guest addition and it destroyed the mouse integration which is now disabled after starting the VM even though it is enabled on the setting menu. 

Now I can't figure out how to install the guest additions without a working mouse as the it involves clicking on Windows buttons inaccessible from the arrow keys of the mac keyboards which just do not move the cursor from one button to the next. The mouse of the host does not merge with the mouse of the guest. So now I am stuck with a completely unusable VM. I tried to upgrade to VB 6.1.0 and downgrade to 5.2.10 from a backup but still no mouse integration with either of those. 

I tried to change the pointing device from USB tablet to  PS/2 Mouse, the graphic controller to VBoxVGA,  VBoxSVGA and even VMSVGA, the USB controller to 3, 2 and 1, disable my filters, enable and disable 3D and 2D acceleration,  but none of these attempts make neither the mouse integration nor the full screen option work.

The performance of the VBoxSVGA adapter in scaled (200% autoscale) output on a MacBook Pro with retina display is really bad. When I switch to unscaled 100% output the performance gets better, but then everything becomes unreadable.

The performance issue can easily be seen when having 200% autoscale output on a retina display and then clicking the start menu. The start menu appears slowly with poor performance.

I've noticed that since some versions back, heavy graphics activity inside the guest causes extremely high CPU usage, bringing the guest to a crawl. The guest becomes unuseable slow and after some seconds the entire VM-Windows locks up and no longer redraws; interestingly this only affects the GUI, the VM itself continues running (I can see it's network-traffic).

""Heavy graphics activity"" in this context seems to be anything that causes lots of redraws. This includes simple GUI-animations, videos, or anything else which causes fast redraws inside the guest. 

Since the VM-logs show nothing of interest, I did acquire a CPU usage profile while a simple program inside the VM hammers it with window-redraws. It seems the redraws cause an event-storm in VirtualBox's Cocoa implementation: While the VM crawls and ultimately locks, the VirtualBox-process spends all of it's CPU-time inside the QEventLoop, specifically CGContextDrawImage.

My semi-educated guess is that the event-loop drowns in redraw requests which take much longer to process on the host than to generate in the guest.

I've attached the profile taken while VirtualBox is locked up.

Before version 6 scaling used to work fine all the time. Now it's wrong almost all the time. At first I tried using the new VBoxSVGA adapter, but since the graphics are very broken #18397 I had to change it to the old VBoxVGA adapter, which works much better. Running without 3D acceleration is out of the question since the performance is totally unusable.

I usually run the VM in fullscreen at one of four virtual macOS desktops.

Usually I'm switching a lot between using the built-in retina display and two different external non-retina displays (one at the time) In between the switching I usually put my mac into sleep. After waking it up, the windows guest usually have very incorrect scaling. Sometimes it's half the size (half-pixels) and sometimes it's the double size (double pixels) and sometimes it's correct size (normal pixels). 

The solution is to switch between 100% scaling and 200% scaling or vice versa. That works most of the time unless it's in half-size (half pixels), then I have to shut down and restart the VM. I'm not sure why the 200% mode is called ""auto-scale"" since it never auto scales from a user perspective.

I also tried switching between fullscreen and normal mode, but that makes no difference.

On top of this, the VM screen is black some times after waking up. The only solution to that is to try a ACPI-shutdown and if that fails power off the VM and then restart."	klas

On Windows 10 guest copying a folder with a name beginning with a dot (“.”) to a shared folder results in an incomplete copy. For example a Visual Studio project folder with a “.vs” child folder.

'''Steps to reproduce:'''
 * Setup Win 10 guest.
 * Install Guest additions.
 * Create a shared folder on host and mount it in guest.
 * Using a command prompt to create a folder with a name beginning with a dot (e.g. md “.test”).
 * Create a file under .test such as “New Test Document.txt”.
 * In File Explorer right-click .test and select copy.
 * Right-click a destination folder on a shared folder, right-click and and paste.

I disabled SIP, and All issues were solved.
After installation of VirtualBox 6. the Windows guest worked again
Enabled SIP again and the kernel errors appeared again
Can there be a setting change in my host that Im unaware of? I found other cases where users turned off SIP some time ago. So I think SIP is the strong medicine for another small issue.
Have you seen this before? I might have surged with the wrong key words. I dont know which rights need to be set for the kernel. I didnt change any settings actively so this must have happend during the update.

'''What's wrong:'''[[BR]]

After installed VirtualBox GuestAddition(with build-in version or  5.0.0 RC1,RC2,RC3 or whatever the latest 5.0.1 test version),the Unscaled HiDPI Support was broken.The entire monitor image distortion where the mouse pointer are.Look at the screenshot(which means what I see from screen).

But at the same time ,use the '''build-in''' screenshot(which means use the VBox toolbar option),everything '''looks''' OK.

[[BR]]

'''What I do:'''[[BR]]

After installed the older GuestAddtion(VBoxGuestAdditions_5.0.0_BETA4,link here: [http://download.virtualbox.org/virtualbox/5.0.0_BETA4/VBoxGuestAdditions_5.0.0_BETA4.iso])[[BR]]
it works OK! But this GuestAddition may cause WPF-Application crash(include VS2015 or some Metro Apps),and the latest version GuestAddtion(VBoxGuestAdditions_5.0.1-101689.iso) also have this bug.So there are no way to keep both useable and Retina support...Therefore I think maybe some commits after that '''BETA4''' reinsert this bug.....
[[BR]]

'''What I guess:'''[[BR]]

Windows 8.1/10 use the new DPI-Aware API([https://msdn.microsoft.com/en-us/library/windows/desktop/dn469266%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396])[[BR]]
which may behave differently from Windows 8.[[BR]]
So this may be fixed by find the bug commit or add some special judgement code? I don't sure this may happen only in OS X Guest or All platforms.But i'm hopefully to fix this..

The last version that this worked was 5.0.4 and even then it was a little buggy (not expanding past the dock and other weirdness).

If you are running a guest with two virtual displays, when you expand one display to full screen (green icon), it will hide the other virtual windows. When you 4-finger-up to manage windows, you only see ""VirtualBox VM"" instead of the guest name. In 5.0.4- you saw to entries labeled ""vm guest name 1"" and ""vm guest name 2"".

Issue:

Copying any rich-text data from within the Windows 10 guest is not paste-able into the Mac OS host.  This is somewhat new behavior that was introduced with a clipboard crash fix in the release after version 5.1.32.  

Before the crash fix was made, pasting copied rich-text from the guest onto the host pasted the plain text extracted from the clipboard.  While not as ""perfect"" of a feature solution as being able to paste the full rich-text, plain text pasting would be welcomed back with open arms.  An ongoing discussion is here:

https://forums.virtualbox.org/viewtopic.php?f=8&t=86056&sid=ef11b0345dfa4278164ef407b4f4a626

While most of the commenters experiencing this bug are seeing the issue with Microsoft Office products, I also see it with Chrome and Firefox.  To reproduce, do the following:

1) within Win10 guest, browse to Google from within Chrome or Firefox, do a search for ""virtualbox""
2) highlight and copy the first found result, which is ""Oracle VM Virtualbox"".  I copied the entire result listing: title, URL, description.
3) hit CTRL+C or right-click/copy
4) mouse-out to Mac OS host and paste into any app such as TextEdit: no data is pasted.

The very inconvenient workaround that most people do is to paste the data into Notepad within the Win10 guest, copy that data, then paste into the host.  A nicer solution that still requires an extra click is to install the PureText app within Win10, which when used, strips the rich text and makes the plain text paste-able into the Mac OS host.

We would like to have the ability to paste any text data (as at the minimum plain text) into the host, which was working in VirtualBox up until and including 5.1.32.

2D Acceleration is activated 

Hoever when running a OpenGL based application in the guest (e.g. Solidworks) it always messes up the display by showing buffered window contents (which are either in the background or contents of windows that have already been closed)  right on top of parts of the openGL window. It happens most of the time when the mouse is moved around.  

I have seen this problem around for quite a while now (using Virtualbox since Version 3.x) and this issue somehow has never been solved.

Is there any hint, patch or workaround? 
Disabling the 3D Acceleration completely solves the problem but the CAD application gets terribly slow then. 

Thank you very much.

Re: Bluetooth disconnect when starting W10 64bit on OS X host
Postby rcatyvr » 17. Dec 2016, 23:45

Problem hunted down and solved for now:

Latest VirtualBox on El Capitan Mac, latest Window 10 from upgrade on 64 bit VM. 

Starting the VM caused my host Mac's Bluetooth services to stop and refuse to connect to my keyboard and trackpad and from operating inside/outside of, or after closing the VBox application. It is a BIG problem as the only way to close the VM  and restart my host's Bluetooth was to power off then reboot the computer which is an annoying waste of time and can break the HFS+ file system.

Fortunately, I found a wireless Logitech keyboard & mouse handy so I plugged the dongle into my USB hub and was able to continue to troubleshoot without having to crash the system repeatedly just to close the VM

Solution/Work around:

You will need to have at least a wireless or hard wired USB mouse plugged in. Especially if you are using a Mac, be sure that before the Windows VM actually starts to boot that you prevent it from going full screen and you lose the ability to click on the Apple control icon at the top left of the host's screen to do a controlled reboot. If you don't you will probably have to power the unit off the hard way. Note: a similar keyboard setup would help, but is not essential as both in the VM and the host, a functioning mouse can get you through to solution. 

1. Confirmed that I had replicable problem--repeatedly from cold start to full power-off crash.
2. Used an archived Win 10 VDI dated September 22, 2016 to confirm the problem originates in fact in Windows, not VBox--no problems seen
3. Went back to the most up-to-date Windows 10 VDI: Services control, I stopped & disabled: a) Bluetooth Handsfree Service, b) Bluetooth Support Service.
4. REBOOTed the Windows VM
5. Tested and had no further interference with the host's Bluetooth hardware.

Problem solved. I would call this a solution, though it is technically a work around, because disabling Windows' bluetooth should be moot. The host shouldn't be able to pass those services to the VM and therefore there is no need for them to even be there/on. However, that as by default they try to start up (and revert to a manual-start service) at boot time, and as it seems that just querying for the hardware is enough to crash the host's own hardware, those services should be disabled.

I don't know how it does it, but have I found out experimentally that in a VBox VM, Windows 10's bluetooth services/hardware layer have been recently changed and are now somehow attempting to control/attach to the host's Bluetooth stack during the client's boot up--causing them to crash and the host loose its hardware bluetooth service. Not supposed to happen, but it does. 

A long term solution would be for Oracle to figure how the Win10 VM is trying to access the hosts' hardware and crash it, and prevent it from doing so."	rcatyvr

15817	Display with Windows 10 guest and OSX host is corrupted	Mac OS X	VirtualBox 5.1.4	2016-08-18T08:01:01Z	2016-09-26T09:38:03Z	2016-09-26T09:38:03Z	"I have installed Windows 10 on my retina MacBook Pro and on my (non retina) iMac. Unfortunately with the latest release of VirtualBox the display on a Windows host is corrupted.

Specifically, when I start typing or I perform any mouse-related gui-event activity (i.e. press a button, select some text), then the square area that takes part of this activity is grayed out. Note that only the ""refresh"" part of the screen is damaged, not the whole screen.

If for example VB loose focus and gains it again (i.e. when the display is forced to redisplay/redraw) then the visual returns to normal.

As an example I attach a screenshot. I have clicked on the language button of the Windows login screen at the bottom, where a pop-up appears to select languages as well as on the text field to write the username. For these actions, all partially redrawn screen sections are completely grayed out, making the interface totally unusable."	terataki

If the user has a trackpad or a laptop, and enables ""3 finger drag"", you can hold the ctl key and select the individual items by pointing to each item and doing a 3 finger drag with the ctl key held down.  however, this won't work with a mouse, not even the current touch sensitive apple mouse."	ascott

I have a large ZIP file (837MB) in a directory on my host.

To reproduce:
1) Create a shared folder mapped to the directory containing the zip on the host
2) Copy the ZIP to a local guest directory (IMPORTANT)
3) Attempt to unzip the file using windows native tools, Java's jar.exe or 7zip.  
They will each fail with fairly meaningless error message.  
Windows Extract All... says: ""Error 0x80004005: Unspecified error""
Java's jar says: ""java.util.zip.ZipException: invalid stored block lengths""

Note that step #2 is important.  Unziping the file in place from the share seems to work so something is occurring when the file is copied.
I've also confirmed that MD5 hash of the file does indeed change after it is copied from the share.  I used this tool from Microsoft to compute the hash.  http://support.microsoft.com/kb/841290/en-us"	kminder

Strangely it seemed to happen less often with Safari but that could just be a coincidence because sometimes it would not happen at all, however each time I was copying the exact same text, a C# class from a github raw file view.

Another note is that if I did not copy a second time, the paste would always be the same and contain the same extra/strange characters on the end, however it would never be in the clipboard on the mac/host side, only on the windows/guest side.

I tried posting this before by including the strange text and I received errors that my post was not long enough (and then lost my entire post  :oops: ) so I am including these as images now to hopefully prevent this issue...

I've seen it where the cursor did NOT change (it happened once, so I'm not sure if this is as designed or what) but the behavior seems to be inconsistent, and it's now changing again.  I would prefer that it doesn't change because I'm using a ""resized"" (accessibility settings) cursor in my macOS host, which distorts the guest cursor to a grotesque pixelated monstrosity.

Steps to reproduce:

1) Open a Windows 7 guest OS.
2) Put the window on a second monitor.
3) Close the Macbook lid to cause the MacOS to sleep.
4) Open the Macbook lid.
5) For a moment you will see no windows from any application, then most of them will pop back up.
6) VirtualBox Guest OS Window never reappears.
7) Clicking ""Show"" button in VirtualBox Manager does nothing.

Workaround: Use Remote Desktop to shutdown the OS and restart.

Please note that the length of time in sleep should be a long time.  Merely closing and opening the MacBook lid for a few seconds will probably not trigger this behavior.

If the user has very small dock icons, the live preview has minimal benefit, so a static OS icon would allow quicker identification of the relevant VM.

Also, the Live Preview icon should allow the user to turn off the 'iMac-like' bezel surrounding the preview. This is a subjective design choice that some (I think many) users would like to remove. Dock icons are usually something that are very easy to modify in OS X so being locked into a set style is quite frustrating."	Kieran

 1. recommended system settings to enable AIO (e.g. kern.aioprocmac sysctl on OS X)
 2. several settings are referenced in the logs (cache commit interval, cache commit threshold), but it's not clear where these settings are made and where it might be appropriate to change them
 3. it's not clear where to get metrics to determine whether tunings are working as expected or where problems may crop up in the I/O path

In terms of metrics and debug, I've got a number of cases where CPU utilisation on Windows guests maxes out in the middle of disk I/O, and I can't really tell at what level the problem occurs. I noticed that SAS controllers don't produce metrics at all. Perhaps more importantly, the primary metrics interfaces don't appear to show disk I/O (I can only find this through the session information dialog in the GUI) or allow me to understand how the queuing looks to the guest or how it's being passed on to the host. I can't really understand whether there's some synchronisation problem in the drivers in the guest that are causing the problem or whether the guest is queuing I/O faster than the host is dispatching it, leading Windows to throw a tantrum because I/Os are appearing to time out or some such. As this is an issue where the guest hangs without giving me much in the way of data about whatever it was that caused it to hang (and this is in the middle of things like running Windows Update, so it's not the kind of case where a hang would be expected), it would be extremely useful to be able to observe the guest behaviour as it interacts with the virtualisation layer to get some idea of what's going on in there."

5808	Session information should prefer to wrap at word breaks and punctuation	Mac OS X	VirtualBox 3.1.2	2009-12-20T11:03:57Z	2009-12-20T11:03:57Z	2009-12-20T11:03:57Z	"The session information dialog wraps text in a fairly annoying way. I understand that someone felt wrapping was important, but it'd be great if a word wrapping/sentence wrapping algorithm was employed instead of merely treating all characters as equal.

Steps:
 1. setup Windows 7 with a fairly typically setup
 2. install guest additions
 3. start Windows 7
 4. open the session information dialog

Once created, these interfaces show up to OS X as if they were additional physical interfaces, but do not show up as usable host interfaces in virtualbox.  If it could be possible to use these interfaces in virtualbox it would make an enormous different to my ability to use virtualbox on an OS X host as a server virtualization solution in my production environment.  Without it I am limited to only being able to have virtual machines on as many subnets as I have physical NICs.  

From reading through other posts etc, it seems as if this functionality may already be present in the windows version?

3422	USB Filter does not distinguish two or more identical USB devices	Mac OS X	VirtualBox 2.1.4	2009-02-23T11:00:50Z	2009-03-25T19:28:13Z	2009-03-25T19:28:13Z	"Actually I want to overcome the problem described in ticket #373. It is really problematic not able to enter backslash and other chars on a German keyboard layout.

I use the Microsoft Natural Ergonomic Keyboard 4000 with a Mac Mini. Host is Mac OS X Leopard. 

My idea was the following: I tried to use two identical USB keyboards. One should be connected to the host. The other should be connected to the guest. However, when I enter the USB filter dialog, the virtualbox lists two devices with identical name ""Microsoft Natural Ergonomic Keyboard 4000 [0173]"". I selected one of both to be used with the guest.

Then, I started the guest Windows XP. However, instead of connecting only one device of both to the guest, the virtualbox connects both USB devices (Not okay). It should be possible to distinguish between identical devices in case of multiplicity.


Then, I tried to use this with Windows Vista x64 as guest. Forget it, it starts to toggling and never starts up.

21325	Enhancement: enable high refresh rates (frame rates?) in guests	other	VirtualBox-7.0.4	2022-12-06T02:47:35Z	2022-12-06T02:47:35Z	2022-12-06T02:47:35Z	"From what I understand, VirtualBox caps the refresh rate (or frame rate - not sure which terminology is correct) of the guest's display to 60Hz, and attempting to force any refresh rates higher than that is pointless.

This results in a very noticeable drop in smoothness when using the guest operating system on a host machine with a high refresh rate.

Simple tasks such as dragging or resizing GUI windows are noticeably laggier than on the host OS.

For example, I'm using a Windows host on a monitor which supports 200Hz. The host OS feels far, far more responsive and enjoyable to use than any of the guest machines.

I am not a VirtualBox developer so I don't know the technical details, but it would be great if it was possible to allow VirtualBox guests to output higher refresh/frame rates, up to and including the refresh rate set on the host OS."	Jenkins1

will not restore the window size but instead use a too small window. 

This is a regression from 1.x to 2.1. 

How to reproduce:

1. Start VM

2. Enable ""auto-resize guest display""

3. Close VM window choosing ""save machine state""

4. Start the VM again

5. While restoring, the VM window has a certain small size (640x480 or so)

6. When the VM is fully restored, the VM window HEIGHT is restored but the 
WIDTH is unchanged from restore operation. In the next moment, the guest 
OS changes its screen size to adopt to the new size. 

Result: Saving the state at a window size of 1600x1200 results in a restored 
window of 640x1200. 

WM is fvwm2. 
WM is unlikely to cause the problem because when ""auto-resize guest display"" is not active, restoring the vM will resize the window corretly to the same size it had when saving the state. "	joseph_

I rebooted windows. Same issue.

- I just discovered that downgrading fixed the problem.
I looked in windows update history and saw:
- on 05/11/2022, (one day before my ""Update and restart"" though this one http://support.microsoft.com/kb/890830. Others are too old

Also, working on a professional laptop, with windows administration by our IT team, I saw this notification after the ""update and restart"" of windows (did not have time to screenshot it), it was saying something like ""an administrator has changed the rights on some path...""
Don't know if it helps.

I have attached the log file and a screen.

Any advice or suggestion would be very helpful.

there are various combination I have checked,

but it is a (completely empty before any installation) Windows 10 based machine.
nothing unusual other than that it is set to UEFI, and 
and I have also set modifyvm (machine name) --nested-hw-virt on

Screen reader doesn't announce any elements, it keeps saying ""Unknown"" while tabbing, so it is impossible to shut down the virtual machine using the screen reader.

Please note that the newest Dell BIOS (A14) for this laptop will support a hardware virtualization CPU in the same socket as is now holding Intel T4300 CPU but the CPU installed does not support this.

1633	Windows XP cannot boot natively after installation of Guest Additions (BSOD during boot)	other	VirtualBox 4.0.6	2008-05-29T06:19:47Z	2020-08-28T20:29:11Z	2020-08-28T20:29:11Z	"I have successfully managed to run Windows XP Home / SP3 from a raw partition within Virtual Box on an OpenSUSE 10.3 Linux host. Without Guest Additions installed, the windows installation can be booted both natively as well as in a virtual machine.

Once the Guest Additions are installed, booting natively fails. Immediately after showing the initial Windows splash screen, the mouse pointer appears in the center of the black screen, and the machine locks up completely. The keyboard doesn't react at all; doing a CTRL-ALT-DEL, for example, doesn't work.

I have further managed to reproduce the problem by simply installing the Guest Additions into the natively running Windows (from a CD-Rom that contains the Guest Additions). Installation apparently proceeds without problems (no warnings or error messages), but the machine freezes up at the next native boot as described above. Booting into the virtual machine is fine (and the Guest Additions work properly).

In both cases, the windows Windows installation boots natively again after the Guest Additions have been uninstalled, e.g. from within a virtual machine. On the first native boot of the Windows installation, some device drivers are apparently reinstalled (Graphics and Mouse, I think).

If a native boot has failed with the Guest Additions installed, all Linux partitions (extfs3) are checked during the next Linux boot because of not being unmounted properly, although the previous Linux shutdown proceeded without problems. The NTFS partition holding the Windows install is also flagged as being not clean (an ntfs-3g mount has to be forced, for example, and during a boot into a virtual machine the Windows installation starts up with offering to boot into previous configurations or a safe mode).

The problems manifest as freezes/pauses/hangs in the UI. The whole display output freezes and a bit later suddenly jumps to the desired output. This is especially visible in continuus animations, but annoying everywhere, especially while typing text.

This happens at least with:
* VBoxVGA without 3D acceleration
* VBoxSVGA without 3D acceleration
* VBoxSVGA with 3D acceleration

I didn't test VMSVGA. 2D-video acceleration settings don't seem to have an effect on the problem.

When I downgrade to 5.2.x (last I tried was 5.2.22) the problem is gone.

With 6.0.2 and 6.0.4 it was very easy to reproduce the problem, nearly every start of the guest showed it. With later versions (6.0.10 and especially 6.0.12) it got better (harder to reproduce). Now the problem only shows up every ~10 starts of the guest.

To get or ""fix"" the problem it is not enough to do a restart of the guest. A full shutdown and cold start is requried.
Additionally the problem can also start when you resume the guest from a saved state. But it seems like a resume can not ""fix"" it.

Just after importing it, it works fine. But if I log on to Windows with another user and try to add (via ""Machine -> Add"" in VirtualBox Manager) the already imported virtual machine, I get an error message with result code ""VBOX_E_OBJECT_NOT_FOUND (0x80BB0001)"", and the operation fails. In the details, it says ""Could not find an open hard disk with UUID ..."". Also, when I'm logged with the same Windows user that imported the .ova appliance, if I remove the virtual machine (without deleting its files) and then try to add it again (""Machine -> Add""), I get the same error. These problems never happened to me on 5.2 versions.

I've realized that, just after importing the .ova appliance, the '''.vbox''' file lacks section '''<MediaRegistry>''', and also subsection '''<HardDisks>'''. Despite this, for the same Windows user that has imported the appliance, for some reason it works at first.

A workaround that I've found is, just after importing the .ova appliance, to remove hard disks attachments and then add them again. Doing this, section <MediaRegistry> (and subsection <HardDisks>) gets written in .vbox file. After this operation, other Windows users can add the virtual machine.

The snapshot feature really makes it easy to test and rollback changes when needed.

16896	strange slow behavior in highly specific example	other	VirtualBox 5.1.22	2017-07-11T21:01:12Z	2017-07-26T19:20:14Z	2017-07-26T19:20:14Z	"We use a program Plexon Offline Sorter to manipulate acquired data. Specifically, on an iMac with an i5 (identifier 15,1), the most recent version of Virtualbox (5.1.22), the program is impossible to manipulate data because it's too slow. It's not clear at which version of Virtualbox the program became unusably slow. 5.0.36 works fine. In addition, and quite oddly, the current version works fine when tested on a Mac Pro using the same vdi file. I tried to maintain the same settings in the vbox.

To reproduce this requires a number of steps.

The program is available for download at http://www.plexon.com/sites/default/files/OFSx64v3w7Setup.exe. 

It is installed on a Windows 7 SP1 x64 guest machine with security updates current as of 6/17. The RAM is set to 3072 MB.

An example data file can be found at https://drive.google.com/file/d/0B9hWBqS8eh_QUkZlYVNla0c3ODQ/view?usp=sharing

We configure Plexon to open this file by selecting for its extension, .nev, in the open file dialog.

Once the file is open, click on the channel 1 marker to select that channel. The center window is where manipulation takes place. Hold down the control key and drag shapes around the data with the left mouse button held down. The mouse should draw in real-time and then fill in the shapes once the mouse is released.

As mentioned above, on this particular iMac, this worked with older versions of Virtualbox such as 5.0.36. In the current version, the mouse dragging barely registers because the program can't keep up. "	mauricev

15818	Windows 10 guest VM has shared folder hang	other	VirtualBox 5.1.4	2016-08-18T10:33:07Z	2016-08-18T14:56:33Z	2016-08-18T14:56:33Z	"
== The Issue ==

On using Visual Studio 2013 on my Windows 10 VM to build a project located on a VirtualBox shared folder, Visual Studio will hang during some file I/O operation such as scanning files for intellisense or compiling the C++ source files. Once it is hanging, I cannot access the shared folder via the Windows file explorer which suggests something has failed in the shared folder file operation(s), and the Visual Studio process cannot be terminated. Indeed, even shutting down the VM hangs on the shutdown screen and I must manually force a VM power off. Interestingly or not, copying the entire project folder from the shared folder to the guest C: drive worked without any issues, and then subsequent build operations from the C: drive work fine without any hanging.

This problem appears to have started happening since version 5.1.x. It was happening after I initially upgraded to 5.1.2 but then seemed to sort itself out, but since upgrading to 5.1.4 it is happening constantly (or maybe I'm just being lucky / unlucky depending on timings).

There doesn't appear to be anything in the VM host syslog related to disk I/O at the time that the VM shared folder access hangs but VM startup does produce the following in the syslog:

{{{
Aug 18 11:21:35 centurion kernel: [69073.711857] vboxdrv: ffffffffc0121020 VMMR0.r0

Aug 18 11:21:35 centurion kernel: [69074.056132] vboxdrv: ffffffffc023f020 VBoxEhciR0.r0
}}}

The VM log (attached) doesn't appear to me to have anything in there related to the shared folder hang. Is there any more verbose logging that can be enabled for the VM?

Following the installation of 4.3.30, this no longer works. Doubleclicking text selects a whole word, but you cannot extend it by dragging. The drag does nothing.

This doesn't seem to be possible with VirtualBox. When I go to ""VirtualBox Shared Folders"" in the network, I see one entry by shared folder and I have to map each folder to a network drive, which sucks if I have a bunch of shared folders.

if you use Windows XP in a VM and shut down after loading the snapshot, you want to retain settings (folders and files) from the Windows profile. There are the shared folder. Problem but if its Windows software in the Windows user settings constant user settings stores. With Linux, you could now create a symbolic link (ln-s newLink Target) but in Windows NT / XP, there is no symbolic links by default. It can also create tools using junctions but it does not work with network sources. ""vboxsvr"" is but an emulated network adapter. Symbolic links with a common goal in order Windows NT / XP do not work also. This is a critical problem. For Windows <NT / XP would be necessary to integrate different shared folder in Windows (mount).




Original text:

Hallo,

wenn man Windows XP in einer vM benutzt und es nach dem starten/beenden immer wieder auf einen Snapshot zurück setzten lässt, möchte man Einstellungen (Ordner und Dateien) aus dem Windows Profil beibehalten. Dafür gibt es den Gemeinsamen Ordner. Problem ist aber wenn Windows Software ihre Benutzereinstellungen konstant im Windows Profil abspeichert. Bei Linux könnte man nun einen symbolischen Link erstellen (ln -s neuerLink Ziel) aber bei Windows NT/XP gibt es standartmäßig keine symbolischen Links. Es lassen sich aber mittels Tools Junctions erstellen aber es funktioniert nicht mit Netzwerkquellen. ""vboxsvr"" ist aber ein emulierter Netzwerkadapter. Symbolische Verknüpfungen mit Ziel in einem Gemeinsamen Order in Windows NT/XP funktionieren also nicht. Das ist ein kritisches Problem. Für Windows < NT/XP müsste man die Gemeinsamen Ordner anders in Windows einbinden (mounten)."	Codename

Guest system: either Windows2000 or WindowsXP with guest additions installed.
Remote desktop connection via rdesktop-vrdp from a linux client connected via 1Gb Ethernet to server.

Problem description:
Running some applications that use vector graphics, like CAD systems, is extremely slow. Sometimes it takes several minutes (!!!) to refresh a screen which otherwise would take a split-second to redraw on a ""real"" PC. On WindowsXP the problem is so severe that sometimes VirtualBox just crashes. During redrawing of the screen the guest system seems totally stalled and unresponsive.
I've experienced this problem with ""Zuken CadStar express"" and running a simulation in Octave with FEMM (The simulation is blazing fast, but redrawing the mesh on screen can take up to 3 minutes!).

Additional information:
Running VirtualBox as X-windows client instead of using VRDP, doen't make much of a difference, it is still horribly slow. Doing the test on VMWare-player, it is fast, sometimes about 20-100 times faster that in VirtualBox.
Ethernet network load also doesn't make any difference.
The speed (or slowliness) varies widely for no apparent reason. Sometimes it is just slow, and sometimes it is very slow. It seems as if drawing time increases exponentially with the complexity of the object that is being drawn, that means that simple drawings most of the time render quickly, whereas more complex drawings go in ""bursts"", slowing to a crawl somewhere in the middle. It becomes so slow, that you can count the indivitual lines being drawn on screen.
All other applications (that do no intense vector drawing on screen) run fine at normal speed, interaction is snappy and even transition effects on menus are quite workable.

It happens with all tested guests (XP, Ubuntu, OpenSolaris, Solaris 10), both with NAT and bridged networking.  The problem did not exist prior to 3.0.0, and has been confirmed both with pre-existing guests and newly created guests.

When you open an FTP session from the guest to the OpenSolaris host, the host returns an error like this one from a NAT guest:

Jun 21 19:50:21 fnog ftpd[1902]: [ID 227848 daemon.warning] refused PORT 10.0.2.15,60783 from fnog [192.168.99.22]

192.168.99.22 is the host IP.

If you do the same with VB 2.2.4 on the same host, ftpd logs no errors and successfully connects the guest.  This has been tested on two different hosts.  Both tested installations of the host OS use an unmodified default ftp configuration.

With FTP servers on the Internet, VB guests connect, but are unable to list files or directories on the FTP server using either the 'ls' or 'dir' commands.  The same FTP servers interact normally with computers that are not VB guests.  One tested example would be ftp.sunfreeware.com.

Shared folders and SSH/SCP/SFTP exhibit no observed problems from guest to host, but are slower for large transfers and for network testing.

on a solaris host (snv_103 X86) with windows XP guests

   ( in all cases below guest additions were installed )

In 2.0.6 I was able to pop up windows explorer with the standard keyboard shortcut of windows-logo key + 'E'

I was also able to take a ""snapshot"" of the active microsoft window with alt+printscreen (for pasting into Word or an Image Tool or whatever)

In 2.1.2 I no longer can.

At first I thought maybe it was me .... but I uninstalled 2.1.2 and re-installed 2.0.6 and the functionality returned.

I recently installed 2.1.4 and the alt-prtscreen seems to work (it seems slower but I'll take it)  BUT the windows-logo key + 'E' to pop up windows explorer still does not work.

If I can be of help to a developer I'm happy to try things out.

However the example given in the documentation does not show which DMI information from dmidecode to use for which parameters.  Several that are shown as being something you can change, like the Release and BIOS Major/Minor values, do not show up in the dmidecode output I see.

I would be very helpful to show example output of dmidecode from a specific system and then show how you use it to set the various values, and what to do if no such value is present.

I have included the full output of dmidecode for my laptop for you to see what it looks like as an attachment to this report.

What happens ? You can move Window when dragging but there is no way to move cursor according to guest OS configuration. Basically mouse cursor movement is desynced from window movement (while dragging windows across monitors). This is wrong and a bug.

When Multi monitor is configured in atypical way, like:

Those changes were done because of the issues in ticket #17225. Because the issues of the other ticket are solved and this is just follow-up issues caused by the changes in the other ticket, I open this one just for those issues.

The issue was already described in the old ticket, I also put some logs there, so I kinda link there for further information and logs (see comment 74 and some previous ones in #17225 for example). Some brief description: as soon as one changes the audio output device on the host (speakers to head phone or Bluetooth; or in the other direction), the guest’s audio output is simply stuck forever in the last second on the old device. The solution is always tricky, I described some of the working ones in the comments of ticket #17225. Sometimes only help is the guest’s reboot."	boxer01

It gets confused as to which monitor the mouse is clicking in, making it pretty much unusable. For example, I have the Windows task bar on the center monitor only, and when I try to click with the mouse pointer located over the Windows start button there, nothing happens. If I move the mouse pointer to the bottom left corner of the left monitor and click there, then the start menu opens on the middle monitor.

Also, when the mouse is in the main window the pointer looks good and stable (although it doesn't work for clicking in that window), but when I move it to one of the other windows then it gets jumpy and fuzzy.

I tried to disable 2 of the monitors from within Windows, but that was almost impossible with the mouse clicking on the wrong one.

Rolled back to 6.1.38 and all is hunky dory again.

I then disabled 2 of the 3 monitors while running in 6.1.38 before re-installing 7.0.0, and then the VM worked fine with just the one monitor. But when I then tried to re-enable a 2nd one, the issue came back."	Ian Puleston

Here my thread on forum https://forums.virtualbox.org/viewtopic.php?f=6&t=106742

I use two VDI on my VM. First VDI: Normal type. Created for system using (OS, applications, system configuration). I want to take snapshots only from Normal disk type.
Second VDI: Write-through type. Created for file storage. I don't want to take snapshot from Write-through disk.
But files are restored on Write-through disk... I do not understand anything.
Please check me step by step. I will try to be as detailed as possible.
1. I created new VM with new VDI (Normal type for system using). Capacity 30GB. Screenshot https://www.dropbox.com/s/gy764nib8kljrdc/Screenshot_8.png?dl=0
2. I created new VDI (Write-through type for file storage). Capacity 50GB. https://www.dropbox.com/s/2g2cfr621yuqo93/Screenshot_12.png?dl=0

I reverted to 6.1.18 and confirmed the issue is not present in this version, with low to minimal VMM Load.

I tested and am not seeing the issue on a Ryzen 5 3400G host at this time. I have performed the same test with multiple vCPUs with 6.1.20, and 6.1.24 and the VMM Load is low in all these cases on a Ryzen host.

20794	Mouse (in both guest and host) behaves strangely when captured.	Windows	VirtualBox 6.1.32	2022-01-28T07:57:13Z	2022-07-02T07:27:42Z	2022-07-02T07:27:42Z	"This bug is new to version 6.x (not sure the exact version it started in, as I just upgraded to 6.1.32 from a 5.x version a few days ago). Also, this bug only happens when using mouse capture (not when using mouse integration). I don't think it's dependent on the guest OS, as it has an impact on the host mouse cursor as well as the guest, but it may be dependent on the host OS (not sure if Linux version of VBox has this bug, as my PC only has Windows on it). It also doesn't matter if it's using capture instead of integration due to Guest Additions not being installed, or due to the mouse integration part of Guest Additions being manually disabled.

The bug causes the the host mouse cursor to be locked into a rectangular region of the screen, which is located in the upper-left hand corner of the host computer screen. It doesn't matter where the guest window is. The locked in rectangle is always in the upper-left corner of the host screen. If you use the mouse to try scroll the cursor out it wraps around.

On the guest side, the moment you move the mouse after capturing the mouse, the guest mouse cursor completely disappears. This aspect of the bug may be dependent on the guest OS, but I haven't tried it in any guest OS other than Windows, so I can't verify this.

As I don't have technical knowledge of the internals of VirtualBox, I don't know what component is responsible for this bug, so I have left that set to ""other"" on this bug report form.

I've attached a video I recorded of my screen using my cellphone camera showing this issue. It shows how it only has an impact when mouse capture is being used, by running an OS with Guest Additions with mouse integration, and then I disable the integration and let the mouse get captured, where the bug then becomes immediately obvious."

21011	guestcontrol in terminated state right after using it on a just restored online snapshot	Windows	VirtualBox 6.1.32	2022-06-28T12:33:40Z	2022-06-28T12:33:40Z	2022-06-28T12:33:40Z	"It seems that the guestcontrol interface goes into terminating state, right after an online snapshot has been restored of a VM (windows 10 image).

This is a problem I detected on a VM with 6.1.32 vbox guest additions installed. This problem is not present on a VM with 6.0.4 vbox guest additions installed.

Steps to reproduce:
{{{
1) load OVA (win10 OVA in my case)
2) start VM and create online snapshot
3) poweroff VM
4) restore online snapshot taken in step 2
5) start VM, now the VM will jumpstart into the (online) machine state as saved in step 2
6) execute a guestcontrol command from the host immediately after step 5
}}}

After step 6, the guestcontrol command returns with this kind of error:
""VBoxManage.exe: error: Error starting guest session (current status is: terminated)""

The best way to reproduce the error is to automate the steps as it seems some race condition being the rootcause here. These were the simple steps I had in my batch script to reproduce the issue:

{{{
@echo off

set VM_NAME=win10_10.0.17_clean

echo restore snapshot on %VM_NAME%
""C:\Program Files\Oracle\VirtualBox\VBoxManage.exe"" snapshot %VM_NAME% restore ""online_snapshot""

echo start VM %VM_NAME%
""C:\Program Files\Oracle\VirtualBox\VBoxManage.exe"" startvm %VM_NAME%

rem echo zzzzz
rem sleep 1

echo execute command via guest control interface
""C:\Program Files\Oracle\VirtualBox\VBoxManage.exe"" guestcontrol %VM_NAME% run --putenv ""USERNAME=user"" --username user --password user  --wait-stdout --wait-stderr --timeout 600000 cmd.exe -- /C ipconfig
}}}

Executing this sequence on a VM with 6.1.32 vbox guest additions results in the mentioned 'terminated' state of the guestcontrol interface. There is not other way to get out of that, by just rebooting the VM. Otherwise, the guestcontrol interface remains in 'terminated' state.

If there is tiny sleep between step 5 & 6 (as can also be seen in the script) the issue is not there, and the command is executed succesfully.

So it seems some sort of race condition.

I have attached some logging. You will see that whenever the issue is there the logs show 'VERR_NOT_FOUND' errors:

In the way, you can launch without trouble on a 64 Gb system 10 (for example) VM that could use each one MAX 16 Gb of memory, if all of these VM only use less than 64 Gb (or better 32 Gb) of RAM in total."	Shine

In contrast, if the guest is running at a 4k resolution (scale to 100%)
see picture_02.png
the mouse pointer is displayed correctly. The behavior is independent of the operating system (Guest). The behavior is independent of the program (Guest). Changing the graphics controller on the guest (VBoxVGA, VBoxSVGA) does not change the behavior. For help, i thank you in advance "	reine667

1. Open `VirtualBox-6.1.30-148432-Win.exe` and proceed with the steps.
2. I get this error while installing
Error:
The Windows Installer Service could not be accessible. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance.
3. And after I hit `OK`. I get the following message.

Symptoms:

When running the OpenGL program Celestia v1.6.1
which is available at http://sourceforge.net/projects/celestia/files/ 
dragging the mouse in its window with either or both mouse buttons held 
down seems to cause the application to receive many more mouse evemts
than it should or to receive unrealistically large mouse motion values.

When the LMB is dragged, the selected object should move the same amount
of distance that the mouse is dragged. Instead it ""leaps off the screen""

When the RMB is dragged, the selected object should rotate smoothly.
Instead it rotates by unpredictably large amounts.

When both buttons are held down simultaneously, the selected object
should move at a moderate speed toward or away from the viewpoint.
Instead it immediately becomes extremely close or invisibly distant.

Exactly the same symptoms are seen when running Celestia in both guests
and whether or not 2D or 3D graphics acceleration is enabled.

These symptoms are not seen when running on the host.

I have a VM named Win8.1, running on a Win10 host, which can be controlled manually via the VM manager.

Now, I'd like to control it via COM, but even the examples shipped with the SDK do not work.


== Python  ==

The file SDKRef.pdf lists the following Python code in section 2.3.1.
I just changed the name of the VM  to Win8.1 and added two print commands:


{{{
import win32com.client
vbox = win32com.client.Dispatch(""VirtualBox.VirtualBox"")
session = win32com.client.Dispatch(""VirtualBox.Session"")
mach = vbox.findMachine(""Win8.1"")
print(""Machine.State: "", mach.State) 
print(""Machine SnapshotFolder: "", mach.SnapshotFolder)
progress = mach.launchVMProcess(session, ""gui"", """")
progress.waitForCompletion(-1)
}}}

The output is:
{{{
Machine.State:  1
Machine SnapshotFolder:  C:\VMs\Win8.1\Snapshots
Traceback (most recent call last):
  File ""C:\Users\webers\Desktop\vbox.py\vbox.py"", line 8, in <module>
    progress = mach.launchVMProcess(session, ""gui"", """")
  File ""<COMObject <unknown>>"", line 2, in launchVMProcess
pywintypes.com_error: (-2147352571, 'Typenkonflikt.', None, 3)
}}}

The output of the two print commands is correct, so COM in general works, but launching the VM fails with error ""Typenkonflikt"" (this is german, so it's not a Python error, but comes from my german VM installation or the german Win10 host)

 
== VBS ==

In sdk\bindings\mscom\vbs\sample, there is this listing, where I only inserted my VM name:

I've also replaced ""openRemoteSesstion"" by ""launchVMProcess"", with the only result that this is replaced in the error message, too.

When I then click on the [Cancel] button, an error popup appears as per the attached file ""VBox Guest Additions (6.1.30) - Pop Up Screen (20211128).jpg"". According to that popup there should be a log file named ""install_ui.log"" in the directory shown. However no such log file is written to the drive. I searched the entire guest operating system drive to be sure it was not written to some other location but no such file exists.

I am including ""VBox Guest (6.1.30) - Operating System Version (20211128).jpg"" to show the version of the VirtualBox Guest that I have the bug on.

Although I am showing only the latest 6.1.30 addition error, I was receiving a similar error for Guest Additions 6.1.28. 

I was hoping 6.1.30 Guest Additions would resolve the problem, but it did not.

I have gone to the trouble of installing a brand new VirtualBox Guest OS running Windows Server 2012 R2, and applying all Microsoft security & critical patches applicable to the operating system, before I then tested Guest Additions 6.1.30. Alas I got the same error.

Just to clarify: Guest Additions 6.1.28 and 6.1.30 installed perfectly on Windows 7, Windows 2016 and Windows 2019 without a problem. I am only experiencing the problem with Windows Server 2012 R2.

20630	Sound disappears after second change from Speaker to Bluetooth Headphones on the host	Windows	VirtualBox 6.1.28	2021-10-24T12:04:54Z	2021-12-13T01:22:32Z	2021-12-13T01:22:32Z	"This is a duplicate of the ticket #20431. The description and the analysis of the issue is already there. The error is here since 4 versions (was caused by the another refactor of sound backend back in the March 2021). It still here in the version 6.1.28 147628 and 6.1.29 147791, so I opened this duplicate.

Quick description here: after the host output device changes from Speaker to Bluetooth, then back to Speaker and then once again to BT, the sound output from VBox is lost. Other application from the host still can use the BT as output, but VBox can only use the Speaker after that. The only remedy is to restart or to save and restore the VM, but this only gives one single more short for the BT. After that the whole situation repeats itself.

20723	Guest can't pick-up/use Host audio device (like BT or USB headset) after the device was physically reconnected/re-plugged (LOGS, STEPS)	Windows	VirtualBox 6.1.30	2021-12-13T01:16:59Z	2021-12-13T01:16:59Z	2021-12-13T01:16:59Z	"Pls advise on temporary workaround (if any), as it blocks from using some of audio devices with VirtualBox (greate solution, btw, thank you so much!)

Steps:
1 Choose some pluggable audio device on Host. It can be any - USB or Bluetooth/BT headset/headphones, behavior is the same
2 Play audio in Guest
3 Disconnect/unplug audio device physically from Host
4 Audio playback falls back properly to the newly selected Host audio device (like speakers of a laptop)
5 Plug-in/reconnect disconnected USB or BT audio device, ensure it's selected as default in Host and audio plays just fine from Host
6 Try to play audio from Guest
RESULT: silence, nothing audible
I've expected audio to play normally, but it can be done only if I restart Guest

What's interesting is that if after step 6 I switch Host's audio device to 
the fallback device (like laptop's speakers), I start to hear Guest's audio. So the audio itself is not broken in Guest.

What I've tried to do to get it back:
* Disable/enable Audio Out/In in VB's toolbar
* Mute/unmute, ensure that all is unmuted after reconnections
* Stop/Start audiosrv and AudioEndpointBuilder on both Host and Guest
    The only uncertain thing here is that after some sequence of Stop/Starts I think audio started to go out to proper device, but then I couldn't reproduce/restore exact sequence of starts/stops so I'm no longer shure it wasn't a misinterpretation.

Pls note that if to change audio device back and forth without disconnecting/unplugging it, all works fine as expected.
Just in case, speaking of BT device - it's connected to the Host's bluetooth not to the Guest bypassing Host (if to pass-through BT device ""Intel Corp. [0002]"" to Guest)

Please help to solve it and if possible, suggest temporary workaround for the issue (through CLI), so I can restore audio without a need to restart Guest.

I've attached two set of verbose logs, ""Audio issue - NOT OK unplugging"" represents the issue. ""Audio issue - OK changing without unplugging"" is for the simple change without unplugging (just in case).

On Intel Core i5 2540M and Intel Core i5-8265U the performance difference was about 50 percent while on AMD Ryzen 5 3600 both VirtualBox and Hyper-V performs almost identical (5 percent difference is as expected). The AMD PC machine has super fast Samsung 980 Pro SSD while the Intel laptop just an ordinary WD SSD. Still the difference is huge.

20609	Poor performance on 4k display with scale factor less than 200%	Windows	VirtualBox 6.1.26	2021-10-16T10:48:12Z	2021-10-16T10:48:12Z	2021-10-16T10:48:12Z	"I'm experiencing problems with VirtualBox 6.1.26 (tried other versions as well, very end of 5 series, and end of 6.0) and 4k external display. My laptop is Lenovo P53 with i7-9850H and Nvidia T2000 graphics card. 4k display needs scaling and when it's set 200% (effective resolution Full HD) then everything is smooth. If I go lower than 200% the screen gets choppy - even when dragging the explorer window very slow refresh rate is noticeable. When I change to 100% for the scale factor everything is very smooth again. My goal is to use 150% scaling and that will give me QHD resolution - but it's impossible to use due to lag. 

I tried all possible options. Adding more CPUs or enabling 3D acceleration doesn't make any difference.  Changing the scale factor from 200% to 199% like with flick of switch affects performance. 

I can't believe that this powerful laptop can't handle a 4k display with scaling. Something is not right here.

Other virtualization software allows the key combination to be seen by the guest by not acting upon said combination until all keys in the combination return up, with no additional keys or mouse clicks preformed between the down/up events of those keys.

The reason for this request is spending an hour tracking down why Ctrl+Alt+Left-Click didn't perform the action I had mapped in Visual Studio.

I notice this usually when i have been or am using the Ultravnc viewer inside the the guest client. It seems to disorient mouse capturing features.

To resolve this, i have to click the mouseintegration button on the lower right and then disable the automatic integration, then manually click the Windows 10 guest and confirm catching the mouse. After confirmation, the system is then responding to mouse clicks (right and left).

This started to happened more frequently, so that I finally could no longer work with that VM and had to recover an older state from a backup. 
Now that some weeks have passed, the issues start again. I upgraded to 6.1.18 without success. Note that I already had issues with shared folders (e.g. can't start executables because they don't exist, copying several files will only copy some files etc)

I can make the VM ""accessible"" again by manually specifying the shared disk in the .vbox file (or temporarily attaching the shared disk to another guest, to have it show up in the media registry).

20109	Guest Bridged Networking Stops Working After Host Link Was Down	Windows	VirtualBox 6.1.16	2020-12-31T00:11:39Z	2020-12-31T00:11:39Z	2020-12-31T00:11:39Z	"I tested bridged networking on a Windows 10 Host with a Windows 7 64-bit Guest and a Windows XP 32-bit Guest.  They both exhibit the same problem with a bridged network adapter.  If the host's bridged link was down when the virtual machine was started, or goes down temporarily after the virtual machine is started, communication is lost through the bridged adapter on the host.  It is still possible to ping the host's address assigned to the real adapter, but no devices connected to the LAN on the real host adapter will communicate.

Virtual Network Adapter
Windows 7 64-bit Intel PRO/1000 MT
Windows XP 32-bit PCnet-FAST III

Host LAN Adapter Intel I219-V (1 Gb) VEN 0x8086 DEV 0x15B8
Host OS Windows 10 64-bit 10.0.19042

The work around for the problem is to temporarily disable and then enable the host LAN adapter using the Network Connections in the Control Panel.  Then disable and enable the virtual network adapter in the devices menu for the virtual machine.  After doing both of those things, the bridged adapter will communicate again.  I have noticed that it sometimes recovers if I just temporarily disable the network adapter for the virtual machine, but that seems to depend on whether the host adapter was up when the virtual machine was started.

I noticed this problem on a LAN port connected to a test network that normally has the switch powered off until I need to run tests.  If I power up the switch after starting the virtual machine then there is no communication to the network switch until I perform the steps that I outlined."	ErikWlfn

I would have to power it down and restart.  Sometimes it would be stable the rest of the day but freeze after resuming it the next day.  Now it is freezing after every resume and sometime after restart.  I've gone back a few snapshots but not change.  Checking for updates says I am on the latest version.  No 3D acceleration enabled.  Host is Windows 10 Pro fully patched.  Guest if fully patched.  Minidump and log attached.	David Shower

Also, there is distortion, popping, crackling, skipping, etc. of the audio.  After switching to AC97 ICH in the guest, the LAGGING problem goes away.  However, the distortion persists.

I followed the steps for Audio Debugging in the Wiki.  The WAV file also exhibits some distortion when played on the host, though perhaps not quite as noticeable as the distortion in the guest.  I am attaching the VBox.log file.

However I did notice that in v6.1.14 it hardly occurred any more, perhaps once a fortnight.

Once I upgraded to v6.1.16, VirtualBox was locking up almost every time the Host resumed from sleep.

After a few days of these lockups I decided to revert to v6.1.14 (29th October) and since then I've not had a single lock up and I've probably resumed the Host from sleep a dozen times.

I've attached the logs from v6.1.16 but from my quick look, I don't think anything gets logged after the sleep as it locks up before that can happen.

I connected my Usb 3 Sata Ssd Mx500 to the host. I can see UASP is supported and enabled in CrystalDisk Info, in Windows 10. However, it is not in the guest (same OS). I have of course installed Virtualbox extension pack.

The difference in speed is high: with CrystalDiskMark, I have around 320MB/s in guest and 450MB/s in host.

Workaround:
Mount the drive in guest. The benchmark shows similar result that in host.

This is a good improvement I think, but no a priority.

When I start my VM I can use the virtual monitor to force the guest to switch the resoution to up to 1600x900. The pull down menu however offers also 1920x1080 and 1920 x 1200. Nothing happens if select them from a lower current guest resultion. 
When expand the guest to maxumum from the host window (auto resizing) I can use the full screen resolution (Great !).
If I click now on in the virtual monitor menu on 1920 x1200 the guest resizes (virtualbox window however remanis maximize).
So there are some issues here on handling the virtual monitor I guess. 
Would be greast offer higher ressultions in the virtual monitor menu for up to the maximum host physical screen resolution (maximizing the host window proofs that the resultions are achievable) but at least that the offered screen resultions in the virtual screen resoltion work properly."

I use screen autosizing to get full-screen display on all my VMs.

The upgrade worked properly for all Windows 10 VMs. However, after upgrading GA to version 6.1.12 on the Windows 7 guest, I ran into repeated blue screens. After changing the graphics driver to VBoxSVGA, I could properly start the VM again, but I couldn't get the screen to autosize anymore.

Actually, the behaviour I observed looks like GA are not working at all anymore on Windows 7 guests.

The only way I could get back this feature (and GA to work properly) was to rollback GA to version 6.1.10.

Bottom line: This looks like a '''compatibility issue between Guest Additions 6.1.12 and Windows 7 hosts'''."	jfmorin

For me, this problem did not exist through many version of VB through 4.2.18 and started with 4.3.4.

The only web research I have was from a VMWare post that may or may not apply here (quoted from cwsault original post):

""There are a few applications which may fail with this error when executed in a VM. The problem is that the library tries to read the instruction bytes of the last FPU instruction executed based on the code segment and instruction pointer saved in the FPU environment. Unfortunately, the code segment saved in the FPU environment may be NULL.

When we switch between the virtual machine monitor and the host operating system, we use the primitive hardware instructions to save and restore the FPU state. These instructions were not really designed for an environment that mixes 32-bit and 64-bit execution. When the instructions are executed in 64-bit mode, they don't keep track of the code segment, since segments have little meaning in 64-bit mode. The virtual machine monitor, which saves and restores the FPU state for the guest VM, executes in 64-bit mode. Hence, the FPU code segment is lost.

Fortunately, there is a workaround for this issue. If you add the following option to your configuration file, we will make sure that the FPU code segment is properly saved and restored when switching between the virtual machine monitor and the host operating system (at some small performance penalty):
    
monitor_control.enable_rigorous_fpu_save_restore = TRUE""

I've been through the documentation many times and asked for help on the forums.  Nobody has been able to find a solution and others have reported that this happens for them as well, including on Mac OS and Windows 7 and 10 hosts.

Host OS = Win 8.1[[br]]
Guest OS = Win XP[[br]]
VB version = 6.1.8, with matching extension pack[[br]]
VRDP Authentication = External/default (VBoxAuth)[[br]]
VRDP Port = 5003[[br]]

This process works fine if Authentication = Null, but when set to External I cannot make a connection from my local host (or any other Windows host) to the guest machine via VRDP. MSTSC tells me ""This computer can't connect to the remote computer"" before it even asks for a login.

I have been trying this on many different versions of VB, going back to the early days of v4.x.  Considering how widespread it seems to be in VB releases and across various hosts, I would think this is a problem that is part of the basic functionality.

A log is attached, but the important message from it seems to be

An app running in the host that is monitoring for the shift using the standard GetAsyncKeyState function receives notification that the shift key is down and thus will respond to it.

I believed the keybard, when captured, should act on all keyboard actions, and not be left for the host (I guess certain reserved keystrokes would be exempt).

This same scenario works fine on VMWare, which is what I am changing from - has worked for many years.

I cannot provide a workaround.

I can provide a program if required to monitor the shift status on the host."	Ken S

I then created a new VBox VM and used the .VMDK as a HDD.

I turned on the VM, let it discover all the drivers it wanted, restarted, etc. Finally i installed VBox drivers from the VM, restarted and everything seemed to work OK. Also performed several old drivers cleanup (uninstallations and removals from device driver), to minimize possible issues.

The VM works fine, except that after some time (randomly, usually 10-20 minutes), it just freezes. VBox's window is responsive but the guest OS is completely frozen. Trying to close the VM from the VBox's close window button, i select ""Send the shutdown signal"" and then press OK. It waits a few seconds and then it just closes the window.

Of course, the next time i start it, Windows report they had not been shutdown properly the last time. Also, the original laptop works just fine."	Wand

I use a virtual machine to work while I stay in quarantine.
Periodically I faced with heisenbug when my host machine freezes.
I had no idea why this was happening.
But today I was able to reproduce the steps that lead to freezing.

So, what I have.
VBox: 6.1.8
Host: win 7 x64
Motherboard: ASUS AC97 rev.2 
Host disk: SSD Plextor PX-128M6S
Host network card: Realtek PCIe GBE (pci\ven_10ec&dev_8168&subsys_85051043&rev_09)

Guest: win 7 x64
Guest virtual network: Bridge / Intel pro 1000MT Desktop
Virtual disk: VHD / AHCI / i/o caching enabled
Virtual chipset: ICH9 / i/o apic enabled


What I do.
When I try to download a large file (e.g. 1 GB) 
then after a while the guest and the host system freezes.. absolutely )))

What could be the real cause of freezing
- bridged network adapter,
- i/o caching, scaling virtual disk,
- or chipset ...
I don't know,
but I tried a dozen variants of parameters,
and all the same, periodically it happens..

High mouse acceleration also causes mouse capture to break free.

P/S2 Mouse, USB Tablet, USB Multi-Touch Tablet produce the same results.

The VM starts normally (although with much less precision in the progress indicator, also since VBox 6.1x) but the VM window, after flashing for a moment at the saved size, shrinks to 640x480 and has to be manually resized, while obviously all the guest's desktop icons get rearranged and any open program windows gets shrunk as well.
This doesn't happen always but often (on an apparently random basis) and never happened, as far as I remember, with previous releases. I couldn't yet spot any clear and reproducible cause.

This is not a major problem, obviously.
However it actually IS some kind of malfunction.

have a virtual world that is frozen in time with virtualbox guest additions service disabled in vw.  when a restore is done, this error now appears.  used to be able to freeze time on vb machine a few versions back without problems and save its state then restore etc.  unable to do this now without getting an error on the restore state.  very problematic. seems like there's some new check that flags the vw when the date is out of sync possibly and its keeping the vw from being restored.

2. Inside this VM, install Total Commander 9.51rc3 (the exact version is important!).
3. Make a backup copy of the TC installation folder.
4. Start TC, then exit it (if you're lucky enough that it does not crash).
5. Compare the TOTALCMD.EXE file contents with the one from the backup copy (for example, you can have another version of TC installed into another directory; there is a built-in function for comparing files).

Result: The file contents is different from what it was initially.

Expected result: The file should not change, because Total Commander does not modify its own executable. This was confirmed by the author of TotalCmd, but just in case I also monitored the situation with Sysinternals FileMon. During the whole period from launching Total Commander to its exit, FileMon showed absolutely NONE write operations to the totalcmd.exe file by any process in the system. And still, the file ended up being modified.

The corruption always happens on cluster-level; that is, the changes always consist of one or more cluster-sized chunks (4096 bytes on my guest file system). The exact position and contents of the corrupted data may vary in different experiments.

The issue can be reproduced in VirtualBox 5.2.36 and 5.2.38. With 5.2.34 I could not reproduce it. For some reason, I could reproduce this issue only with that particular version of Total Commander; neither rc2 nor rc4 seem to trigger the corruption scenario. If the version 9.51rc3 is no longer available at the official web site at some later time, it can still be downloaded from here: http://totalcmd.net/beta/tc951x32_rc3.exe (the authenticity can be validated by the digital signature).

I understand that Win98 is completely outdated, but it's a really serious bug causing data loss! And since I don't know what causes it, I cannot be sure if it does not affect any other guest OS.

I've looked at the log files, but they contain nothing at all at the moment of the experiment. Just in case, I'll attach the log file, but you can see it's empty between 13.5 seconds (when the OS started) and 26-something minutes, when I shut down the guest OS after performing the experiments."

18784	Windows guests hang exactly once after each host reboot	Windows	VirtualBox 5.2.32	2019-07-23T21:53:30Z	2019-12-17T01:21:03Z	2019-12-17T01:21:03Z	"At some point during the 5.2.x series (I don't remember exactly which version), I started consistently experiencing the following problem with VirtualBox on my (64-bit) Windows 10 host.  It occurs only with my Windows (10) guests, not with my (Manjaro) Linux guest.

Whenever I reboot the host, after restarting VirtualBox and my VMs, each Windows guest (but not the Linux one) will freeze exactly once, very soon after its first startup.  When it freezes, if I try to close the window, which causes the ""power off / send reset / etc."" dialog box to come up, then whatever I choose, nothing happens; instead, that dialog box also freezes.  If I choose ""power off"", for example, the guest window does not close.  Then I click the 'x' to close either the dialog box or the host window, and it simply disappears (leaving the guest in the aborted state).

After I restart the guest, it remains up for a very long time.  It never freezes again on the second or ensuing startups, until after I reboot the host again.

This has been happening on all 5.2.x versions since the first one on which it happened (alas I don't remember which one that was).  I'm unable to use 6.0.x because of ticket #14366, so I'm not sure whether the bug also exists there or not.  I think I have had at least one VM freeze on 6.0.10 while checking to see whether ticket #14366 still existed there (it does), so perhaps this bug does still exist on 6.0.x, but I didn't run long enough (because of ticket #14366) to confirm that it was the same behavior (i.e. successful long-term operation on the second and ensuing guest reboots, with the problem recurring only after the next host reboot)."	rokopt

As part of switching to VBoxSVGA I installed the 6.0.12 guest additions with 3D acceleration enabled. 

Following the restart of the guest (eventually multiple times), I consistently get display behavior that effectively makes the VM unusable. What seems to happen is that whatever section of the screen (like an icon, desktop gadget, title bar and occasionally the entire desktop) was updated last is displayed in full screen within the guest.

I will attach a number of screenshots displaying this behavior as I moved my mouse pointer over the guest's screen. Do note that some of those screenshots, being the ones showing the VirtualBox window decorations, were taken in the (Windows 10) host, and some within the guest itself. As you can see, the results are consistent independent of the source of the screenshot."	Rutger van Bergen

Initially I would have random lockups. Suddenly the guest would be unresponsive and after a while it would crash and VirtualBox would report that the guest had aborted. Googling led me to sites that suggested the lockups were usually related to the graphics driver.

I was using VBoxVGA (as I'd originally started on v5.1 of VirtualBox). After lots of reading about the VirtualBox video drivers I discovered I should have been using VBoxSVGA when I upgraded to v6.0 of VirtualBox (currently on v6.0.14).

Since the switch I've not had any lockups but at random times instead my desktop shrinks. I'm using a 4K monitor in Full Screen mode (3840x2160) and when the shrink occurs the Windows 10 desktop has shrunk to 1024x768 and is centred on the screen with a massive black border all around. The guest hasn't crashed and Host+F twice restores the screen to the full size but all my open applications have been squashed too, so I have to resize them.

I asked this question on the forums and it was suggested I log the problem here with logs.

When I originally reported the issue in the forums I was at home using my Windows 7 desktop but it's just occurred while I'm away running the VM on my laptop (Win 10 Home host).

I am not sure when this issue began, but I am assuming during 6.x.

From a known good snapshot, I can boot into NT4 successfully and login as the administrator account.  However, when I reboot the guest, the *next* reboot will fail with this error message:

    HAL: MPS MP Structure not found[[BR]]
    HAL: No MPS Table Found.[[BR]]
    
    HAL: This HAL.DLL requires an MPS version 1.1 system[[BR]]
    Replace HAL.DLL with the correct hal for this system[[BR]]
    The system is halting

The solution that I found is to go into the guest's settings, and under System --> Processor, enable OR disable the ""Enable Nested VT-x/AMD-V"" checkbox.  That means, if the checkbox is currently checked, uncheck it.  If it is not currently checked, check it.  Save and then exit the settings dialog.

After this, the next boot will work fine.  But!  The next time you restart the guest, you must toggle the state of that checkbox again before the guest will successfully boot.

Definitely one of the weirder bugs I've ran into.  I'll attach a screenshot of the HAL message, but I'm not sure what else the VBox developers might need to figure this one out."	kumba

I am running a 32 bit XP VM which I use to run an older drafting program, Drafix CAD. On version 5.2.34 and earlier the cursor displayed properly both on the desktop and within the CAD program. Later updates show an enlarged cursor (regardless of pointer settings in control panel) on both the desktop and within the program. This enlarged cursor is problematic in the CAD program because it creates an offset between where the cursor appears to be and where it actually is which renders the CAD program basically useless. To try to eliminate this problem in 6.0.14 I turned off 3D acceleration, 2D video acceleration, and have tried both VMVGA and VMSVGA modes. Nothing returns the cursor to normal appearance. My workaround is to reinstall 5.2.34. Works fine so I won't be accepting any updates.  	Woodsaregood

First of all the startup time is now double or triple as much as before. One can see the system starting as one would moved back from SSD to plain old HDD. Even if one see something there is a slow reaction on the keyboard and mouse events. So it takes more time from the start of the VM till the moment where you can do something with it.

The other one: as soon as host try to dime the display or turn it off, the content of the VM turns black. The programs work fine and you can hear the sound, but you can’t see anything, just black square. The mouse cursor changes itself in case you move it over some places (like border of the program’s window or the link in the browser). I could blindly shutdown the VM through keyboard commands directly in VM.

Some other tickets (#18564, #18582) are probably depends on this issue.

I tested with 5.2.28, current 5.2.29 and 6.0.7 with the same result. Going back to the 6.0.4, 5.2.26 or 5.2.22 solves this. I saw some changes in the OpenGL using code in the last to weeks, maybe this causing this behavior? I put my logs here, I could see some OpenGL warnings and errors here just 12 minutes after the VM start.

Seems there are at least three people voicing this complaint.

I was using VB 5.2.22 on Win7 host with Win10 guests for a long time. I set the guests to use 3D and 2D acceleration and never noticed an issue.

I rebuilt my host to Win10 v1709, same hardware including the NVIDIA Quadro GPU. I installed VB 6.0.10, created new VMs, and then quickly ran into the shared folder crash, so backed down to 6.0.8.

When I set the Win10 guest to use 2D and 3D (256MB), I have graphics issues. The most notable is that videos won't play in WMP or VLC (audio only, no image shown). There is also a lot of flickering and choppiness in the OS UI. If I toggle off 3D, then videos will play and other OS UI animations are smooth again.

What I -can- do from the VM on the Shared folder is ""Create a file"", and ""Delete a file"".  And I can make a copy of a remote file [copy z:\... z:\...].  I just can't copy from C:\... to Z:\... [VM to Host]

Another important difference is I'm logged into a Domain Joined system in the VM, and Windows Networking with a different userID on the host system. I opened up security on the destination folder to [Everyone-Full Access]"	craiga
18612	VM window can’t be seen or activated after host’s hibernation.

This happened only once, but I couldn’t find any similar ticket, so I file this one here. After my host was woken up from the hibernation I couldn’t activate the VM window. It can’t be seen in the taskbar, only the manager’s window is here and can be seen and activated. Beside the VM window is present in the list of the running applications (Alt + Tab) but you can’t activate it here as well. What could be done is: save the state of the VM from menu in the manager window and start it again. This way the window of VM appears in taskbar and can bee fully seen and activated. I put my logs here, probably somebody could see what went wrong here.	boxer01

So after some issues appeared on the 5.1.32 it now gets even worth. On Windows 8 host / Windows 7 guest combination sound works nearly fine but completely disappears after some minutes. And there is nothing in the logs, everything looks fine here. On Windows 10 host and guest combination I can’t get any sound at all. Everything is kind of here and presented, but if you try to play something in the guest, the playing software got some seconds of hesitation at the first moment and then time starts to run without a sound. At the second try everything starts immediately but also without a sound. Going back to the previous version helps of course.

For socratis: I know that this is 1001 ticket about this, but I file it anyway. Because it is a new version and it’s a new behavior. So now I’m back to the 5.1.30 where I have no problems with sound. And in my case I simply see further declining in this version after we already got some slight problems in 5.1.32. Anyway I like to thank anybody how is working on this problem."	boxer01

The situation has changed after some experiments in the audio back end. So now this distortion is always slightly here and can be clearly heard. But not in the dumped files. Previously this distortion came for thirty seconds every 5 or 7 minutes, but then the sound was heavily distorted. Hope this would help to locate and eliminate this issue.	boxer01

This occurs after the progress bar for the restore has reached 100%. It does not happen every time I try and restore a machine, but once it does happen, it will happen every time I try and restore that particular machine until I discard the saved state. Therefore, I suspect the problem is occurring while saving the state.

Both host and guest are Windows 7 64-bit. I have yet to experience this on other guest operating systems, but I have not used saved state on other guests as much as the Windows 7 ones, so that may be pure chance.

I'm experiencing an issue with the mouse pointer in the latest release. When mouse integration is enabled the mouse pointer is distorted and very difficult to use. If I disable the mouse integration it looks and behaves as expected. I have looked on the forums and can't see any bugs logged for this version.

Because of my issues (#18359) with SVGA adapter driver (not the current version is used even if current version of non-WDDM driver was previously installed) I tried the new approach. The new version of experimental (WDDM) driver was installed before the switch from the VGA to SVGA, after the non-experimental driver was already installed previously from the safe mode boot. As a result after the required restart of the guest OS I got the guru meditation. 

Side note: I installed the experimental driver in the normal mode, I didn’t boot the OS in the safe mode,because for the experimental drivers this isn’t a requirement. Other note: if I install the experimental driver (I say no to the standard one after activating the Direct3D support during the guest addition installation) in the safe mode, I have no issues with my desktop Java application, [https://forums.virtualbox.org/viewtopic.php?f=2&t=85458 TV Browser].

18359	Wrong driver in the Windows 7 guest after the switch to the VBox SVGA adapter.	Windows	VirtualBox 6.0.2	2019-01-25T07:13:14Z	2019-02-05T07:25:49Z	2019-02-05T07:25:49Z	"I have a Windows 7 guest on the Windows 8 host. Because it’s new, after the test with an old VGA adapter I tested the new VBox SVGA adapter. After the first start the new device was automatically detected and installed. I have had to reboot the guest and after the reboot the new driver was active and I even had the Windows Aero activated.

Because of the problem I already posted in the forum (if I activate the experimental WDDM driver, my only Java desktop program, the TV Browser, has big skinning issues and becomes unusable) I usually install a regular driver with non-experimental Direct3D support only (Virtual Box Graphics Adapter). I have to boot my guest in safe mode for installation because of this. But time after time I test the experimental one. So after the reboot I found that the device name is “Virtual Box Graphics Adapter for Windows Vista and 7” now and beside the working Aero I also have the already mentioned issues in my Java program. More important: the driver version is 5.2.1 and it’s from the end of the year 2017. This was probably the last time I tested the experimental Aero supported drivers.

So I have to boot in safe mode once again, re-install the guest additions, but this time I answered “no” in the dialog about installing the regular Direct3D drivers and not the experimental WDDM ones. It looks for me, that by activating SVGA adapter the other device is simulated and under Windows 7 and Vista the Aero WDDM driver is used. And if one doesn’t install or re-install the additions explicitly, the wrong version of the drivers are used.

This was my experience from my test of original 6.0 release from December 2018. As I tested the 6.0.2 release, the new device was also detected and the driver was also installed. But this was probably once again not the newest one, so after the reboot I had the BSOD on the boot, more then once. Therefore, I have to repeat the additions installation and this way probably renew the Aero WDDM driver as well. After that the BSOD was gone, but I got the same situation with Aero and Java program as I already had before."	boxer01

In Word or any other text editor (like Notepad++) where the cursor should be an I-beam it pretty much disappears.

The host and the guest can not ping each other , neither can the guest ping anything outside of its own machine. 

This issue I have narrowed down to having a locally administered MAC address with in the Guest machine.  While the work around is to use the VirtualBox setting as the MAC address - this is not the preferred method for portability of the Disk Image File. I had narrowed it down by swapping the bound network interface lan and wifi to network 1 and network 2 and then reversing that - disabling the first network with in the guest (which had the locally administered address) - everything then worked - and I only realized it was the MAC address being locally administered within the guest - because I needed to set it for Network2 at which point everything failed to communicate again. 
I then administered the local mac in the Vbox Settings network page. I would prefer this to be with in the image itself in network properties. If I have several images with the same locally administered MAC , I would think the VBox Bridge would act as the router hop so that I could  have multiple of this image on the same network.

I am running Vista 64 Ultimate (same problem with Win 7 64 RTM) with a guest machine running Windows XP Sp3. The most important aspects of this setup is that the guest machine is set to be bridged to my WLAN card (Intel 4965AG). I am using static IP's with a router.

After the Guest OS is installed, I have configured an IP address. I can ping the router from the Host OS and I can also ping the router from the Guest OS. All other aspects of networking seem to be working. (I do not use DHCP purely because of my network setup but I feel this is unimportant).

I have several PPPoE accounts and a router that is in bridge mode. When I try to initiate a PPPoE connection in the Guest OS (WinXP), PADI packets leave the guest machine, go through the bridged network, reach the router. The router then sends a PADO response which can be seen on the Host OS and is also passed on to the Guest OS.

Unfortunately, the Guest OS is ignoring these packets as the target MAC address does not seem to be for the Guest OS (Which is understandable, but surely the bridging driver/service installed on the Host OS NIC is supposed to correct this?)

This seems to be a problem with the bridging driver/service for VirtualBox. This may not be of any concern to you, but the problem also exists in VMware Workstation. This is not a problem for Microsoft Virtual Machine though.

I have discovered a slight workaround. If I set the MAC address of the virtual network card in the guest to the same MAC address of the Host OS WLAN card, the PADO packets are relayed and it now works. Unfortunately, this causes other problems with Linux Guest's trying to use the same workaround and I cannot use this solution permanently.

I have attached the Vbox.log, as well as two wireshark captures from both the host and the guest machine."	Kinnoken

Same error occurs when dragging folder with zero-length file from guest to host.

After that error any other drag-and-drop operation even with non-enpty files fails with error:

Steps to reproduce:
1) Install guest Windows 7 or Windows XP (any language in to the VB) 
2) Install VB Additions
3) Turn on drag-and-drop from guest to host (or bidirectional)
4) Drag and drop any non-zero-length file to check that it works
5) Create any new empty file (for ex. new notepad document)
6) Drag it from guest to host
7) Get error

It is possible to ""reset"" the satuation by trying to drag any file from host to guest. May be not immediately, may be couple of times.
I did not find exact scenario. 
Sometimes attempts to drag files from host to guest after error leads to guest interface partially hang. In that case shutdown procedure asks to forcibly close VBoxTrayDnDWnd.

Additional: errors appear in host log files, not in guest.

The sequence of events scenario was similar both times: I'll typically leave a few guests running full-screen in the background, remote into the host while away, reconnect to the local host console upon returning, then remote in again next day. On the 1st remote connection, the full-screen guests that were left running flash the hosts Windows taskbar, and switching to them restores the full-screen display. Upon the 2nd or so remote connection, the full-screen guests that were left running again flash the host's Windows taskbar, and clicking then to switch to them causes them to crash with (latest example):

In all cases, the Remote Desktop client is set to start full-screen on 1 display. Not sure if this could be the reason or if it could be caused by the host having two different screens (speculation of course). However, simply connecting to a host should not crash guest VMs.

2. Portable Webcam (http://sourceforge.net/p/portablewebcam)

I am currently using VirtualBox 5.2.8 w. Guest Edition and Extension Pack. I select the WebCam under devices (and not in USB devices). The camera is recognized in Device manager. However, the Camera is not working;
1. Microsoft LifeCam software: ""No Camera found""

I can use the camera in the Host, using either application, even when virtual box is running with the camera attached to the Guest (Should that work? I had expected the Guest to take ownership of the camera).

I also tried Logitech C270 Webcam and I have the same problem.

VB works however; when in the guest opening Notepad++ and any other apps with text boxes the mouse cursor disappears, I need to change the Input mouse setting to see the cursor. This is annoying since I've uninstalled VB extensions and reinstalled and it requires the Host hot key to exit the VM Guest.

This only occurs when guest is used on secondary monitors. When on the SurfaceBook main screen no issue.  External monitor(s) are attached via the Docking station, and I've tested with the built Display port and had same results there as well.

Most likely, the cause of the issue, that my host (it has a C2D P8400 CPU) is running the 32bit version of Windows 7. Altought, it'd be not a problem at all, as long, as VT-x is turned on, in both the BIOS and the VM and the CPU has 64bit support. Nonetheless, installing this OS is currently impossible, because guest is always going to hang, shortly after starting (captured wbem file is attached).
Anyways, i'm pretty sure, VT-x is enabled system-wide, because when i disable it in BIOS, i get the expected error message:

Also i'm sure, the bug is hiding somewhere in Virtualbox's Windows 10 support, since right after this, i successfully managed to install a 64bit Windows 7 system on exactly the same guest and host (screenshot is attached of this).

True, the send side pauses happen far less often than in version 5.1.10, but they still happen. They happen on Windows 10 host and on an interface that has no guests bound to it. I'm going to attach log from a guest, because it may have important information about the host, but this issue really applies to the host and not a guest.

16361	Windows XP guest keeps crashing in recent releases	Windows	VirtualBox 5.1.12	2017-01-06T05:08:15Z	2018-03-22T02:34:05Z	2018-03-22T02:34:05Z	"I can't tell exactly when this started, but the XP guest was very stable in versions 4.3 and 5.0 (at least the early ones). The guest keeps crashing now at random intervals, so the regression could have been introduced with version 5.1. I didn't upgrade to version 5.1 from 5.0 right away as there were audio issues initially, and when the audio was ""fixed"" the 5.1.x version was already ""broken"" for that XP client. That XP client heavily uses network adapter, but I'm not sure if that's a contributing factor or not. The host is Windows 10 version 1607.

BTW, this is not related to this issue, but I want to mention this for clarity. Bug #16221 did not concern Linux client only. I had major issues with transmit pauses (between few seconds to few minutes) on Windows 10 host. So the bug affected Windows also and also host network interface. It seems to be fixed now, so I'm not going to open a new ticket unless I notice a troubling network interface behavior, but the comment that bug #16221 was concerning Linux only (wrong) client (wrong again) troubles me that there could be things not fixed correctly. Like I said, no issue with pausing after upgrading to 5.1.12.

17321	Unhandled exception in DirectSound	Windows	VirtualBox 5.2.0	2017-11-28T14:04:43Z	2018-03-18T04:47:20Z	2018-03-18T04:47:20Z	"Vbox crashes when resume a vm on my win 10 host. It happens 90% of time to vm which has audio enabled.

There is a problem with my windows 10. The DirectSound device has a problem(0x88890008, I don't think the meaning of the code is ERROR_NOT_ENOUGH_MEMORY). The error causes any application which uses DirectSound no sound on my win host. The other applications(such as media player, audio player) simply have no sound output. It should not cause the crash though.

A suggestion from me is to check this exception and ignore it(or report to user whichever solution applies to your coding standard). No crash is expected. I knows the issue with DirectSound so I do expect some of applications do not output sound. It is good to have an option to select device from DirectSound or WASAPI. Audio output available when switch to WASAPI in some applications. It's very strange.

If you need more info, I'll attach log files.

The guest is frequently hanging, becoming completely unresponsive; when it does, VirtualBox Manager will oftentimes be unresponsive, too. My only recourse is to close either the guest or the VirtualBox Manager, sometimes having to resort to doing so via Task Manager. After such an event, the guest has a status of ""Aborted"" but I can re-start it without apparent issue.

The guest just froze again; VirtualBox Manager didn't freeze this time. The VirtualBox Log Viewer lists five log files; however, I don't see much of interest therein except the last line which reads (in VBox.log and VBox.log.2) ""GUI: Request to close machine-window."", (in VBoxHardening.log) ""4a88.4ccc: supR3HardNtChildWaitFor[1]: Quitting: ExitCode=0xcfffffff (rcNtWait=0x0, rcNt1=0x0, rcNt2=0x103, rcNt3=0x103, 1429056 ms, the end);"", and (in VBox.log.3) ""GUI: Passing request to close Runtime UI from machine-logic to UI session."" I've attached the log from Machine > Show Log > Save.

Any suggestions on how to resolve this issue?"	CGW

Especially when it plays for the first time after VM launch.

When I launched for the first time a Windows 10 FCU in the VirtualBox running also on Windows 10 FCU, immediately after lauch the OneDrive toasted has popped out and I've heard something like very loud white noise instead of Windows 10 notification sound. The next times, VM tried to play sound it was less distorted but still very much.

When I set the volume in sound mixer on VM to smaller value, it's less distorted, then I set volume to bigger value, it's more distorted.

I use the VM with the following setting:
-3 GB of RAM, 32 GB of HDD as SATA drive
-2 CPU cores
-2D video and 3D graphics acceleration enabled
-Intel HD Audio
-USB 1.1 enabled
-EFI disabled

17538	Virtual Box displays black screen	Windows	VirtualBox 5.2.6	2018-02-11T22:31:28Z	2018-02-12T11:31:18Z	2018-02-12T11:31:18Z	I have been using Virtual Box for a class I am in for college. The other day I tried to bring up my Virtual Box VM program and only had a black screen. I have attached a picture showing what my screen has. It just sits there and not doing anything. I have loaded up a new OVA file for my VM program and still get same thing. What can I do to fix this or what is causing this. I have been using Virtual Box and this program for about 4 weeks now.	fuzzwuzzy13
17535	Guest Additions contain old DirectX9 DLLs	Windows	VirtualBox 5.2.6	2018-02-09T17:29:02Z	2018-02-12T11:09:20Z	2018-02-12T11:09:20Z	"Hello,

when installing the Guest Additions, the following files are replaced d3d8.dll and d3d9.dll. Unfortunately this are old DLL versions (it should be at least 5.03.2600.5512), the Oracle Version is 5.02.0006.20293. So DxDiag shows an error with those two files. Furthermore, it seems that this error is also causing sound issues with iTunes and VirtualDj 8, as there is a crackling in the sound. Both are using DirectX.

Can you please fix this in the next version of the GuestAdditions?

Kindest regards,
Heiko"	Boettgerie

[[Image(ticket:1:ErrorMessage2.gif)]]

My previous laptop is running Win7x64 and I am using VirtualBox 5.1.30 r11838. This has been upgraded as releases have come out so I am not sure what version of VirtualBox I was using when I created the VMs. Each machine is running a similar copy of Windows Server 2008 R2.

I have attached the VBoxHardening.log file for one of the VMs- they are all causing the same error.

I was able to open a few of the VMs once, but then after either powering off  (no saved state) or saving, I get the error message again on restart. I  have tried headless, normal, and detached starts. 

I know this issue has been raised on past versions of VirtualBox, but I didn't see a method for fixing the error which worked- I have un-installed and re-installed VirtualBox, I have tried to recreate the VMs using the same hard disk image, I have turned off my virus software, I have confirmed that I do not have the layout registry key (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers), and I have done a software scan (sfc /scannow). I would appreciate any assistance in trying to solve this issue."	mdr

Virtual box will allow me to connect the 5880 from the USB devices menu. It then indicates a lot of flashing red/green lights on the USB icon, but my smart card software inside the guest (ActivClient) does not recognize that a reader is present. Inserting/removing the card has no effect.

My configuration:
* Windows 7 64-bit Professional on the host, 8GB RAM
* Windows 2008 R2 64-bit as the guest, 3.5GB RAM

I just updated to VirtualBox 4.2 but have tried this on a bunch of previous 4.0 and 4.1 versions. I was hoping this would eventually be fixed. My googling through the community indicates that others have had this problem and it has never been solved.

Any idea how to make this work or whether it will be fixed?

the only way to reboot a windows host (ie for windows updates) is to use vboxtray which detects the reboot and auto-saves state of the guests...

I'm running 2 guests on a windows server which I can only get to remotely... as soon as I issue a restart (or windows udpates do) it kills my remote connection but the server is left hanging there as it cannot shutdown the guest's running on it. I end up having to get someone to manually click close / force reboot etc,etc to get the host server to shutdown / reboot.

the server can reboot / shutdown automatically for various resaons such as a UPS shutting the server down after a power cut...

as I say vboxtray manages to just about get round this by auto-save state but surely virtualbox host or guest apps could do with a settings that detects host shutdown (whether guest is in GUI or headless mode) and does a save state as a default and helps the windows host do a clean shutdown / reboot???


I have this problem on all version of VB since I started using it on 3.2.6 and I've tried it on different HOST machines - win xp pro, win 7 biz, server 2003 64bit.

Without vboxtray we wouldn't have a get round solution, which sort of works but I find that vboxtray sometimes closes on the tray so can fall over too sometimes.

can this be added as a feature request for windows hosts please

many thanks"	Jimbo

""Windows 7 64-bit - Opera Portable"". This is a linked clone of the above which I then have Opera Portable on.

The guest machine has both 2D and 3D acceleration enabled and virtual GPU RAM size is set all the way up to 256 MiB.

When I install guest additions, it works great at first. But when I maximize the guest window (which sets the guest's screen size at 3840x2055) and attempt to reboot the VM in that state, the guest OS tries to switch to that screen mode (borders of the black screen in guest window expand to the desired size) for a brief moment, but then BSODs with SYSTEM_THREAD_EXCEPTION_NOT_HANDLED.

The only way to fix this is to select low-res mode from recovery boot options and set some lower resolution so that it gets saved in the registry - rebooting in normal mode works fine afterwards.

So all in all, it seems like the virtual GPU driver crashes if screen size is too big at boot time, even though it can switch to such mode just fine on a fully booted system."	kFYatek

- an application using P2P connectivity is let to operate for a few minutes (5 minutes should be more than enough);
- you may close the P2P application when you want to get to the next step. Wherever you close the P2P application and its active connections won't make a difference;
- pause the VM execution for a few minutes (5 minutes should be more than enough);
- when resuming VM try to repeat the first step and witness the connection failure.
TCP connections seam unaffected.
I only tested NAT network.

I reproduced this with [http://www.sopcast.com Sopcast] which is a P2P application.
- Install the latest version (4.2.0) in a Windows VM;
- Visit [http:///www.cooltvi.com cooltvi.com] in Internet Explorer and select a channel;
- Allow the ActiveX to run - this would start the live broadcast which is P2P based. 
Sopcast requires Direct3D9 for video to render. But this is not required to reproduce this issue, it can very well be reproduced with black screen.

I could reproduce with Windows xp/posready 2009, 7, 8.1 and 10 guests.

Hi, we have several troubles with a COM Add In using VSTO technics. What happens: The COM Add In does more then one clipboard operation in one thread (using the copy-paste-commands of the application). It works fine, except if: Virtual Box is running (on the host System where the Add In runs), with Windows Guest System and installed Virtual Box Extensions and with at least one user. Then we get clipboard errors, which show, that after a copy command the clipboard is empty or contains invalid data for the paste command. These errors don't occur, if there is no user on the guest machine or if there is a user, but the Virtual Box extensions are not installed. We feel there is a big bug in the Virtual Box extensions handling the clipboard.
This error occurs only with Virtual Box (not with MS Virtual PC nor with VM Ware nor with TeamViewer Virtualization) and only with at least one user logged on to the guest and only with installed VB Extensions on the guest. 
The shared clipboard in the General Settings is turned off! I don't believe that the error occurs in our MS Office Solutions with VSTO COM Add Ins (I got the error in other add ins, too: clipboard empty or invalid data) because of the mentioned circumstances."	EP

usbLibDevCfgDrGet: DeviceIoControl 1 fail winEr (31)
}}}

which I've seen in a lot of log files (not related to this problem) on the internet. I'm not really sure if this is an issue o maybe a mis-initialization.

If I re-try assigning the same USB device a second time I see the following message:

{{{
Connessione del dispositivo USB USB Flash Disk [1100] alla macchina virtuale VmXP_Temp non riuscita.

USB device 'USB Flash Disk' with UUID {a416ea81-cffc-4c89-8ce1-80a66a1aedcd} is busy with a previous request. Please try again later.

which might mean something is ""stuck"" in VirtualBox and this may not be an host issue.

The host logs don't contain anything suspicious and the guest logs too (it doesn't seem I reach a point in which the guest sees anything).

I didn't try with a Linux guest but I'm pretty sure that won't make any difference.

Horizontal scrolling does work in every other app, including VBox Manager (within Show Log). Trying the different input device types in VM's settings did not resolve the issue. 

The previous solution of adding a few lines to tp4table.dat used to work (https://forums.lenovo.com/t5/forums/v3_1/forumtopicpage/board-id/tp01_en/thread-id/37809/page/2 and in fact I'm one of the people reporting there that the solution works), but is no longer the case. As a point of difference between the current and previous issue: scrolling in VBox Manager (within Show Log) used to not work unless the tp4table.dat solution was in place. However in the current issue scrolling does work within Show Log of VBox Manager, but horizontal scrolling does not work in Win7 or Linux Guests.

Furthermore, downgrading from 5.1.20 to version 5.0.38 r114632 did not resolve the issue.

Is there any additional information I can provide to request a fix for this?"	R

16605	Network dropouts in guest since Windows 10 update to 1607 version	Windows	VirtualBox 5.1.18	2017-03-24T15:38:35Z	2017-03-31T10:07:18Z	2017-03-31T10:07:18Z	"I got here following situation. I have a Windows 10 x64 guest on the same OS host. Right now I reduced the amount of installed programs in the guest to the minimum to find the culprit. So right now there is an antivirus (latest Nod32), Firefox and MP3 Player (Xmplay) beside the OS itself. I use the last program for Internet radio since XP days, and there were no problem until now, in and outside the VM. 

Since guest update to the 1607 I can see following behavior: after 15 or 20 minutes of the streaming player starts to buffer at 70-80 % spontaneously around once in a minute, which breaks a streaming experience. One still can listen to the radio, but this is a little bit annoying. This problem only occurs if the Firefox also running in the guest. Something, I don’t know what, but probably some advertisement or data refresh, loads a little amount of the data over and over again once in nearly a minute. I got some network bandwidth pictures which explain the network flow better. But the problem isn’t a bandwidth itself – I can run a bandwidth test, which would use the whole bandwidth and still there would be no buffering. The problem is a timing, because as one can see we have something like 6 or 8 KB/s from the stream constantly, but once in a while the browser adds some 18-20 KB/s to it. So after a while there are some de-synchronization in the flow, which causes the buffering.

This only happens in the guest and only if the browser running with some sites open. If one turns the browser off, there is no buffering. Also, this can’t be reproduced running same player and stream on the host, neither with Firefox also opened on the host with some sites in it, or with Firefox running in the guest, causing the same traffic shape on the host. First of all a thought that this was a new issue with a new VB version, but I tested this with following versions (5.0.30 - 36, 5.1.6, 5.1.10, 12, 14, 16, 18) and the picture is always the same. Changing network adapter from 82540EM to paravirtualized also brings no cure. I tested it with following version of the network adapter drivers (virtio-win-0.1.110, 112, 113, 117, 118, 126, 134), but it always looks the same. There were also no such problems as I updated the host first, before the guest. The clean install of the guest OS from the scratch also doesn’t change anything in this case, but installing the previous version of Windows 10 (1511) in the guest solves the problem. I think, that the problem caused by some TCP/IP optimization in the new Windows version, as described [[https://blogs.technet.microsoft.com/networking/2016/07/18/announcing-new-transport-advancements-in-the-anniversary-update-for-windows-10-and-windows-server-2016/|here]], the Initial Congestion Window 10 probably. If this is important – I hear following [[https://rfe04.akacast.akamaistream.net/7/509/437762/v1/ibb.akacast.akamaistream.net/rfe04?download=1|stream]] for example, but I think any other stream should also do the job. I would like to debug the network stack in the guest, but I don’t know how.

Bi-directional drag-and-drop is enabled.  Beginning immediately after booting, moving a file from desktop on primary monitor to secondary monitor works fine.  Attempting to drag a file back from secondary monitor to primary causes screen lockup when transitioning across screen boundaries, even before releasing left mouse button.  Clicking start orb brings up menu, which then becomes permanent on screen.  CPU usage indicator looks like it goes to 50%.  Session information shows disk read data continuously climbing.  Inserting ctrl-alt-del brings up full-screen menu.  Process monitor will come up if selected, but response is extremely slow.  Switching users from ctrl-alt-del back to same (only defined user) comes back to black screens.  Logout and then login from ctrl-alt-del menu clears the problem and screens are unlocked until trying to do another d&d from secondary to primary monitor.  Enabling/disabling 2D and 3D acceleration has no effect.  Switching drag-and-drop to host-to-guest solves the problem, while obviously losing guest-to-host functionality.

See [http://koussilicious.blogspot.ca/2016/12/70-462-training-kit-setup-preparation.html]; these instructions are for Hyper-V but I thought it would work in VirtualBox.

I was able to successfully clone once. But when I did the second, I got this message:

So in thinking it was that you could not have multiple clones, I tried a clone of a clone. The UI allowed this, but when clicking Create, I got a similar message. When trying to do this a second time to get the error details, the clone on a clone was disabled.

One thing to note is that, as soon as the above happened, the parent VHD was hopelessly corrupted, requiring the VM to be deleted and the VHD to also be deleted."	Will Power

I’m using VirtualBox 5.1.10 in Windows 10 on an Acer Extensa 5635Z laptop, with a T4200 processor (32-bit, no VT-x) and 2Mb RAM.
The problem does not happen on my other machine, which has a Core i5 (2500) processor amd 16Gb RAM.

I'm using a VM with xp sp3 (home edition) as guest and Win10 Home as host.
Under the VM I develop using the old Ca-clipper compiler: the compiler and the sources, together with the files for testing, are stored on the hd of Win10 and I access them by shared folders on the VM.
When I use CA-Clipper directory() function to get a list of files stored on a shared folder, the return value (directory() returns an array of filenames) is empty, like in the folder there isn't any file.
I investigated deeply and I found that if in the folders there are no more than 8 files the function returns a correct array.
Then I copied all the test shared folder, locally on the hd of the VM, and when I launched the program and tested the directory() function, it runs without any problem and returns all the filenames that are stored on the folder, no matter if they are more then 8, 1000, or more.
To be sure that it's not a Clipper related problem (maybe with shared folders), I tested the program with WMWare. I exported the Virtualbox VM and then imported in WmWare, created the shared folders (like in Virtualbox) and launched the program to read the content of shared folder: in this case there was any problem and the content of the test (shared) folder was returned entirely. So I think the problem is related to VirtualBox.

Marco"	mark63

The guest additions worked properly in VirtualBox 5.0.24 and earlier. In all 5.1 versions (5.1.0 - 5.1.4) the following problems are observed: 

•the guest additions icon does not appear in the system tray;  


•seamless mode is disabled and does not switch; 


•mouse wheel does not response.



I also noticed that VBoxTray process gets started but then terminates in approximately a minute after the start and guest additions icon never appears.


This problem pertains in my virtual machine with Windows XP what I used continuously with Virtual Box 5.0.24 without any problems. 


Other guest OS including Windows 7, 8.1 and 10 do not have this problem.

16089	MultiMonitor: Guest mode hints do not accept negative numbers for xOrigin in setModeHint.	Windows	VirtualBox 5.0.26	2016-10-20T12:20:33Z	2016-10-20T12:26:58Z	2016-10-20T12:26:58Z	"The source of the bug is in VBoxHelpers.cpp (hlpResizeRect)
it attempts to maintain monitor order on display resize by comparing the monitor rectangles after the resize and finding intersections between adjacent (according to the previous monitor order) rectangles.

The problem happens if the monitor order changes - for instance, suppose we have 2 monitors - 0 and 1. 
{{{
---------- ---------
|   0    | |   1   |
---------- ---------
}}}
Suppose monitor 0 is 1024x768 starting at 0,0 and monitor 1 is 800x600 starting at 1024,0.
Suppose we call setvideomodehint with monitor 1 being moved to -1024,0 in order to move it to the left of monitor 0. 

What will happen now is that when we look for monitors X-positive adjacent to monitor 0, we'll find monitor 1.
The current code to check whether the monitors now intersect (post potential resize) is: 
(assume iRect=0 and iNextRect=1)
{{{
int delta = paNewRects[iRect].right - paNewRects[iNextRect].left;
}}}
this will result in 1024 (right of monitor 0) - -1024 (new left of monitor 1) = 2048.
next, 
{{{
        if (delta != 0)
        {
            DDCLOG((""XP intersection right %d left %d, diff %d\n"",
                     paNewRects[iRect].right, paNewRects[iNextRect].left,
                     delta));

            paNewRects[iNextRect].left += delta;
            paNewRects[iNextRect].right += delta;
        }
}}}
since delta != 0, we will now move monitor 1 on the x axis by 2048, which will lead to monitor 1 
being in the exact same location before we tried to move it. 
(-1024 + 2048 = 1024)
and we'll end up with the original monitor layout. 


Note the processing of the mode hint event from line 1689 in the log file.

My host is windows 8.1 64bit, my guests are a mixture of windows clients (32 and 64 bit) and a mixture of windows servers (32 and 64 bit) and i have the same issue with all of them.

i can start the vms, issue guestcontrol and guestproperty commands and they all run perfectly. However when i use the command:

{{{vboxmanage.exe guestcontrol ""vm name"" updatega}}}

it sits there waiting to talk to my guest vm and then times out with a bunch of errors about not being able to communicate with the vm.

Example errors are
{{{
ERROR [COM]: aRC=VBOX_E_IPRT_ERROR (0x80bb0005) aIID={13a11514-402e-022e-6180-c3944de3f9c8} aComponent={GuestWrap} aText={Could not open guest session: VERR_TIMEOUT}, preserve=false aResultDetail=0

}}}
Searching around didnt yield any help and it was only when i looked closely at the guest did i notice that the vBoxService crashed.

I ran the service in the foreground using:

{{{vBoxService.exe -f}}}

and even with verbose does not produce any error in the console window, but does generate the following in the event log:

At some point I transitioned to using the virtio-net driver and it worked well for a long time.  

At some point a few months ago the VPN became very unstable.  I would experience random disconnects, especially during periods of constant VPN utilization (screen sharing, large file transfers, etc).  

When it disconnected, it would reconnect, but would not configure the ip stack properly and I could not pass any traffic without disconnecting and reconnecting.  I lived with this for several months and decided to finally take some time to see if I could find a solution.

Ultimately, going to a virtualized Intel PRO/1000 MT Desktop adapter seemed to fix the problems.  For some reason it appears that recent versions of AnyConnect stopped working well with the virtio-net adapter.

I don't know if this would be an AnyConnect, a VirtualBox, or a VirtIO-net issue, and will not be offended if this gets closed immediately.  However I wanted to be sure it was documented somewhere for anyone else who may experience these issues in the future."	J. Fry

I attach my VHD file on Windows 7 host. It's virtual size is 50G and it has one partition formatted to NTFS. I created a dummy VM in VBox GUI to manage snapshots. Currently, the chain consists of 4 image files. 

I didn't boot the guest until now. When I did, guest chkdsk spew tons of errors. Then I stopped the guest and attached the VHD on host again. chkdsk showed no errors.

I went further and restored the 'good' backup (there's a backup of all the .vhd and .vbox files I made before the guest boot). Marked the volume as readonly using diskpart and compared the contents of the block device using cygwin. They're indeed different!

Recently I encountered a Windows guest that hung itself and would not allow me to stop it when right-clicking the VM->Close->Power off. I am running it in headless mode and I saw the vBoxHeadless.exe process on the host was reporting a constant CPU usage value but was not changing, indicating the process was hung.

There are 6 other guests running on this host, all of which did not hang and continued operating properly.

The guest had been booted at 6/30/16 01:31 and some logging software of mine stopped receiving a ping from the guest around 7/9/16 13:30 (232:57 in logfile). I did not attempt to intervene until 20 hours later (252:29 in logfile). It looks like when the guest host process hung the AHCI controller experienced an issue with port resets.

The host is running Windows Server 2008 R2, the guest is running the same.

I have a 5 button + scroll wheel mouse (Evoluent VerticalMouse 4 USB) and I want to use the middle (3rd) mouse button or scrollwheel as doubleclick in my guest system. Before VirtualBox 5.0 (versions 4.3.x) that was no problem and the middle mouse button was detected.
I use the 3rd party software ""X-Mouse Button Control"" (highrez.co.uk/downloads/XMouseButtonControl.htm) to assign mouse buttons to functions, but in VirtualBox 5.0.x the middle mouse button is only detected as left mouse button. Same goes for the scroll wheel.

The USB filter for the mouse does not work either, besides this is not an option for me because I want to use the mouse in the host and guest system.
Is there a solution?

But I have found a strange issue, and can't find a solution here.
Last days I am testing VBox with windows 7 (64bit) embedded guests.
In my latest builds, everything works fine until I install Guest Additions, then drag and drop (in windows explorer and desktop) stops working completely in guest. If I uninstall Guest Additions then it starts working again. 
Also I get some errors trying to run some exe files (mainly installers) from host shares. But if I copy the directory to my desktop or some network share, then the same installers work just fine.
It happens with v. 5.0.10 and also with latest 5.0.12 (with their respective Guest Additions versions), I'll try with older/stabler versions.
I haven't had these problems with Windows 7/8 guests, maybe something related with Windows Embedded. If I install that same image to a real computer, drag and drop works just fine.
Any ideas of what might be happening?
My host has Windows 8.1.

https://ma.ttias.be/auto-resize-screen-size-windows-10-guest-vms-virtualbox/

I am running Windows 10 guest under Windows 10 host.

After I start virtual machine:
Guest display is autoresized, but ""Auto-resize guest display"" checkbox inside top menu bar is disabled (greyed).

After I login to my Windows account on guest system:
""Auto-resize guest display"" checkbox is enabled, but it does not do anything. I would expect that when I uncheck this checkbox guest display would toggle to fixed size and when I check it guest display would toggle to flexible size. However, this does not happen. Guest display does not react to checking/unchecking ""Auto-resize guest display"" checkbox.

If I click on ""Resize to ..."":
Guest display toggles to fixed size, however ""Auto-resize guest display"" checkbox remains checked. So, checkbox does not reflect current state of guest display. Next, to return to flexible size I need to click on checkbox twice: the first click will uncheck checkbox and the second click will check checkbox and return display to flexible size.

For me it would be logical if:
""Auto-resize guest display"" option would move to the same menu with ""Resize to ..."". Then I would have: ""640x480 resolution"", ""800x600 resolution"", ..., ""Auto-resize guest display"". Then only one option can be enabled at the same time. Current situation when I can have ""640x480 resolution"" and ""Auto-resize guest display"" enabled at the same time is against the logic. The screen can't have two different sizes at the same time.

But most important issue is:
After some time ""Auto-resize guest display"" features breaks, guest display toggles back to fixed size and does not react to ""Auto-resize guest display"" checkbox any more. I have to reboot to toggle flexible display size on. This happens occasionally. I suspect that this may happen when host system goes to sleep mode or other kind of waiting mode, but I can't say for sure."	i8329

I've an issue when I'm trying to open a file in Excel 2016 from the Explorer under Windows 10 guest. The error says that ""There was a problem sending the command to the program""

Reading different solutions on windows forums I found that if I disable the hardware acceleration graphics in excel, then the file opens normally.

Also it doesn't matter the location of the file. The error happens either if the file is on a local disk(desktop) or shared folder or network mapped folder.

There are some roundabouts where the file opens fine with hardware accelerated graphics enabled:
- If Excel is already open and open a file from the explorer.
- If I open the file form Excel.

The only scenery is opening a file from explorer while the Excel is closed and HW acc graphics is enabled.

After upgrading to VBox 5, it seems that VBox perceives monitor1 as monitor 2 and monitor2 as monitor1. Upon guest startup, 1 window opens at first and XP starts booting. After a while, when switching to graphical environment (during the XP boot process, just before the login screen appears) a 2nd window appears and the XP boot progress is shown in that window (the 2nd instead of the 1st). After that, the guest OS seems to treat the 2nd VBox window as the 1st screen and vice-versa. I enabled the mini-toolbar and set the 1st virtual screen to use host screen 1 but instead it used host screen 2. If VS1 is set to HS2, it works as intended but then if the guest is shut down, the external monitor is plugged-out and the guest is restarted, nothing is shown because in the laptop's monitor, the 2nd VS is supposed to be shown.

13749	Host Screen numbers are reversed in full screen mode	Windows	VirtualBox 4.3.20	2015-01-10T06:01:39Z	2015-11-21T09:06:25Z	2015-11-21T09:06:25Z	"I have two identical monitors. When I run a VM (with a single virtual monitor) in full screen mode, I can use Mini Toolbar, View->Virtual Screen 1 to move the VM from one monitor to the other. However the monitor number is wrong - when I select Host Screen 1 (the left monitor), it puts the VM on monitor 2 (on the right), and vice-versa. I've checked the host machine display properties (including ""Identify"") and verified that host monitor 1 is on the left and 2 is on the right.

It used to work correctly, however I recently swapped the two physical monitors, ie left to right and right to left, and so far as I can tell that's when the problem with virtual box started.

At the time I swapped the monitors, I was doing some fault finding, so the host PC was switched on/off a few times with various combinations of one or both monitors disconnected, primary monitor being one or the other, swapping cables between monitors etc. (Virtual Box was not run at any time during this.) The problem turned out to be a physical/optical defect in one monitor - which was originally my primary monitor (number 1, on the left), so that monitor is now my secondary (number 2, on the right). (Swapping them back is not an option.) After I finished, I went to Windows Control Panel and ensured that monitor 1 (eg as shown by the ""Identify"" button) is on the left and is my main display, and the monitor 2 on the right is the secondary - it had changed during the process of testing. The port on the video card that's used for the left monitor hasn't changed - only the monitors have swapped places.

The host machine appears to correctly identify the monitors, but now Virtual Box puts the full-screen VM on the opposite monitor to what the mini toolbar menu item says.

The problem is not user-specific. I can replicate it with a different user on the same host PC.

Uninstalling/reinstalling VirtualBox does not fix the problem.

I've tried assorted combinations of disconnecting one or other of the monitors, restarting the machine etc, to see if that will fix it, but it doesn't make any difference.

I even reverted to a (Windows Backup and Restore) system image taken before the monitors were swapped, and that didn't fix the problem either.

It's as if VirtualBox's ""host screen 1"" is tied to the original physical monitor 1, rather than the logical monitor 1 (ie as Windows identifies it after swapping them).

Technical details:

Host is Windows 7 Ultimate, SP1, 64-bit. (The problem appears to be independent of the guest OS - I can replicate it with Windows and Ubuntu guests, and no guest OS at all, just the VM BIOS on a newly created VM with no software installed.)

The monitors are both Dell 2209WA.

Video card is AMD Radeon HD 6670.

For this reason, one of the first things I usually do on my host machine is rewire caps-lock to the escape key using AutoHotKey on my host machine.

This worked just fine until the recent update. Every time I would press caps-lock it would be interpreted as an escape everywhere. 

After upgrading to 5.0.10 however, *inside the VM* it interprets caps-lock as both hitting escape *and* hitting caps-lock. This means, that every time I hit it, my vim flips into a bizarre mode where it does unexpected things with every key stroke. It would be one thing if it wasn't interpreted as escape at all but its interpreted as *both*.

So in order to get the intended behavior, I have to hit caps-lock *an even number of times*. However if, I only hit it an odd number of times, things start jumping around all over (because vim in caps lock mode is no fun).

issue #14633, that describes also the audio problem, but may have a different cause.

issue #4088, latency fixes (Windows hosts only; bug ), fixed in the release



To reproduce this: enable 2d/3d video acceleration for the guest, using an usb mouse

Steps to reproduce:[[BR]]

-start the guest[[BR]]-logon, during logon process the screen flickers[[BR]]
-lauch IE, again sometimes the screen flickers during startup of IE[[BR]]
-goto to youtube and start a music video.[[BR]]


-if you don't use the mouse, the sound and video are almost perfect

-hover the mouse above the playing video area[[BR]]
-rapidly move the mouse from left to right/up/down within the video rectangle
a) the sound will become ""choppy"",
b) the video seems also to lag a little


In the previous version (5.0.4) audio was constantly choppy (even without moving the mouse),
as if you put the volume control to high, like to much voltage on a speaker.[[BR]]

In the previous version (5.0.4) the video was constantly lagging, showing blocks, seems to stop some milleseconds 

After installing 5.0.6, the sound and video performs better but it's not solved.

If I disable 2d/3d video acceleration, audio is back to normal, no video lags and no screen flikkering. (don't see a benefit for enabling video acceleration)

Enabling video acceleration and using the usb mouse together seems to cause the problem.

May be both have an issue.

Attached logs and the description might lead to a solution?

With symlinks on Windows hosts, FILE_ATTRIBUTE_REPARSE_POINT is set to true.

FILE_ATTRIBUTE_REPARSE_POINT should be set to false for all vboxsf files/folders, because being a symlink should only be relevant to the host, and the information should be hidden to the guest.

This is causing us some issues doing PHP development involving symlinked folders, because PHP likes to try and follow the reparse points to convert relative paths to canonical paths.  It attempts to retrieve the reparse point info to conver to the canonical path, then fails.


To reproduce the issue:

I've had a look at the source code for VBox and unfortunately this error is returned in many different situations. To make matters worse the pdmR3LoadR3U function obliterates the original error string which makes it impossible to discover the root cause. All you get is ""Unable to load R3 module"", which is about as useful as a chocolate teapot.

Given that the same DLL works with older versions of VBox (prior to the hardening update) and that the DllMain is never called, I have to assume that this error is related to signature verification issues. However, every tool I've tried tells me that my DLL is signed correctly and that the certificate chain is OK."	Kaloth

I recently installed the Actual Windows Manager application (demo available here: http://www.actualtools.com/windowmanager/) to manage my multiple screens.

I noticed that, when this application is installed, all my virtual machines crashes when I try to open them. After 5 seconds, the virtual machine window freezes, and it's not possible to make any action. I noticed that the virtual machine continues to work on the application main interface (the virtual machine is still updated inside the screenshot control), but the virtual machine display window stops to work, and I have no alternative but to kill it.

When this happens, my machines take the Aborted status, and I cannot do nothing to resolve that. If I try to start my machine again, it restarts normally, but after 5 seconds, the problem returns. All my virtual machines are affected by this issue. If I uninstall the Active Windows Manager, all becomes normal.

Whenever I try and start a VM from the Execute Windows Batch Command inside a freestyle Jenkins job, my VM immediately crashes.

== Details ==
Trying to execute a batch script inside a Jenkins job that starts a Virtual Machine via a batch script will immediately crash and go to the aborted state.

However, the same exact batch script can be ran by the host machine with the same variable and parameters perfectly fine manually. 

Also another workaround is to have the Virtual Box GUI interface open and running and the VM will seem to start.

Is this a permissions issue?

== Steps to be able to duplicate the bug ==
1. Have an instance of Jenkins running on the host machine.
2. Create a freestyle Job that will allow you to execute Windows batch scripts
3. Then create a batch script as such 

{{{
cd ""C:\Program Files\Oracle\VirtualBox""
VBoxManage.exe ""Name_OF_VM""
}}}

4. save and build the job
5. Observer that it starts up but then immediately crashes and goes to the abort state.

 * Windows 8.1 64-bit (Host and Guest)
 * Version 4.3.22

This occurs when the following is performed:

1. VM is running fine, and in Bridged networking mode connected to the LAN network interface. This interface is connected to a wireless router
2. The VM state is saved
3. Host is put to sleep
4. Wireless router is unplugged
5. Host is woken up
6. A different network device, in this case a network hub is plugged into the LAN
7. The VM is started again, and the error appears

The workaround is to delete the savestate and start the VM again.

For interest, the VM is Windows 2012 with 8GB RAM, 2 CPUs and apart from Shared Folders there is nothing fancy configured.

This behaviour does occur for all OSs and configurations.

I would assume this has something to do with when a network interface is disabled and enabled again, it adds ""#2"", ""#3"" next to it. Note, though that no setting in the Host (in Windows 7) shows that the network interface has been renamed, this appears to be the internal NIC name."	georgeby

Host: Windows 8.1 Enterprise 64-bit

Guest: Windows 7 Enterprise 64-bit

Problem:  I am running VirtualBox on a laptop with a secondary monitor connected via a display-port to VGA adapter coming out of the laptop and VGA in on the monitor.  The resolution of the laptop is 3200x1800 and the resolution of the secondary monitor is 1680x1050.  When I move the guest machine from the laptop screen to the secondary monitor I expect the VirtualBox window to resize to the new resolution but it does not. All other applications do this.  This is a bit confusing to explain but bear with me here...

Example:
I start Virtualbox and start my guest machine.  These windows are on my laptop screen and maximized, so running at 3200x1800.  I move the guest machine window over to my secondary monitor but the window does not resize.  I believe the window is still running at 3200X1800 instead of resizing to 1680x1050 when moved.  This is causing issues because the guest machine is pretty much unusable as everything is at a very high resolution but running on a monitor that does not have that resolution.  I can adjust the window or the resolution of the guest machine, but nothing changes.  The window still is running at 3200x1800 thus causing the guest machine to appear very tiny."	gregv

At first I thought it was a memory issue, but it occurs even when there is very little memory load on the host.  Host is XP SP3, Intel Core2Duo, 2.93Ghz, 3GB Ram.  I ran a full memory diagnostic which found no problems.

I've done some experimenting, and I can recreate this issue even with barely any memory load on the host. I rolled back to one of the earlier versions that I knew had worked, 4.2.6, and I cannot recreate a single crash, even with an intentionally heavy memory load on the host. I tried several other 4.2.x builds and stopped at 4.2.16. (Newer builds lead to the well-known security issues that also affect the latest 4.3.x branch).  On all of these 4.2.x builds, I just can't get a crash to happen, no matter how hard I try.

Because this didn't happen at all until I upgrade to 4.3.x, I tend to think there's a regression of some kind in 4.3.x.  If anyone is so kind as to take a look at this, I am more than happy to provide additional logs, testing, or information.

I'm working on a custom-made test automation framework and I was having high hopes with VirtualBox for my VM-based automation needs.
I'd like to see IGuestSession interface augmented with methods such as:

-Get list of ALL guess processes, not only those explicitly created through IGuestSession::CreateProcess()

-Bind/attach to an EXISTING guest process (not previously created via IGuestSession) and get an IProcess object wrapper around it, in order to be able to sync on it (i.e. wait for termination)

Considering how powerful the level of VirtualBox automation is currently (at least for windows guests - i.e. things like auto-logon, process execution, file injection/copying), tt would be a real pity not to have a 1st-class, built-in solution for more complete process management.

By having such support, we wouldn't have to rely on activating network support on the windows guest OS and mess with Microsoft Process/Debug diagnostics API and SMB/RPC calls (i.e. see Process.GetProcesses(string machineAddress) method in .NET Framework)."	smihaila
10242	Need a way to prune snapshot tree	Windows	VirtualBox 4.1.8	2012-02-10T20:02:44Z	2012-02-10T20:02:44Z	2012-02-10T20:02:44Z	"Note: This is ''not'' another complaint about ""Delete Snapshot"". I propose a new feature, regardless of what the snapshot operations are named.

When I have a tree of snapshots, I sometimes want to remove a branch, abandoning the snapshot states, deleting their differencing images and other new disks. I just want part of the machine's state zapped, just as if I had never created it in first place.

Other than hacking XML files, the only way to do this is documented here: 
[http://srackham.wordpress.com/2010/06/18/deleting-virtualbox-snapshots/ Convoluted Pruning Method] (Warning: contains an irrelevant gripe about the name of ""Delete Snapshot"".)


There are some design issues that I've thought of:

- Should the operation be on the parent snapshot (i.e, prune all children)? Or, should it be on the topmost snapshot to be removed?

- What if Current State is one of the decendents? Disallow or offer to restore to one of the snapshots that will remaing?

- There can be only one root snapshot. It necessarily has Current State as a decendent. And with all the snapshots being removed, it would seem appropriate to make the Current State the same as the the root snapshot and then remove all the snapshot. Again, just as if I had never created the root snapshot.

- I'm not looking for a one-click ""nuke it"" operation. As with the other snapshot operations, careful, informative UI design will help users be sure that they are doing the right thing and offer appropriate options or followup actions (e.g., delete disks or keep).

I would like to more easily see which snapshot is its parent. Making it the first child would be one way (whether by a preference setting or otherwise). 

Yes, it could be argued that once the current state has changed (thereby begun serving its purpose), it is the youngest state and therefore should be the last child of the snapshot parent. However, the fact that it has snapshots as siblings is irrelevant to its relationship to its parent and the ultimate purpose of restoring to that snapshot in the first place."	TomB

This has led to corrupted VM Linux filesystems due to executing a VM management task while the VM was in a state that normally would not allow the task to be executed.  

If the VMM is run in the same desktop as the VM, then the status gets updated.

WORKAROUND: verify that the VM is shutdown before performing any management tasks in the VMM.

2. When current state hasn't changed and you restore the nearest snapshot, there's no need to display the confirmation dialog. Nothing gets deleted and the operation is totally reversible (simply by restoring the previous snapshot again).

3. The message that comes up, when you restore a snapshot and current has changed only asks if you want to create a snapshot of current state, but not why I would want that/what happens if I do.
The text should clarify that I can create a branched snapshot tree, something like:
'...... by checking the checkbox below to create a branched snapshot tree; if you don't....'

There is a problem with DOS applications working on folders shared through VBox Guest Additions.

The test configuration is:
  Host:  Win XP, 32-bit /problem also confirmed on Win7 64-bit host/

  Guest: Win XP, 32-bit

  Shared folder: 'D:\' on host shared as 'D'; Drive F: on the guest is mapped to \vboxsvr\D;
  
Problem: A DOS application running on the guest cannot find any file residing on a shared folder. The standard DOS FindFirst function call (INT 21/AH=4E) always fails despite there is files matching to the search criteria. For example FindFirst(""F:\Temp\*.*"") always got error is 0x12 (NO MORE FILES), but there are files in F:\Temp. Furthermore if you call GetExtendedError (INT 21/AH=59h) afterwards it reports error 0xEA which looks meaningless and unrelated to the error returned by FindFirst.

The problem occurs only if you are searching for files on a shares through VirtualBox Guest Additions. It's working correctly with classic SMB network shares.

I tested FindFirst for files on a network drive (e.g. drive 'G:' mapped to a network share) and it works. But if you map G: to \vboxsvr\some-shared-folder then you always got error as described above.

Another test by running 4DOS command shell on the guest shows similar behaviour (4DOS is a popular 16-bit DOS shell like COMMAND.COM). If you type ""dir F:\*.*"", where F: is mapped to \vboxsvr\some-shared-folder you see empty directory listing.

Described problem also appears also on a different machine with Windows 7, 64-bit host."	Dimitar Nanev
8485	Differencing disk created from multiattach base disk is marked as auto-reset	Windows	VirtualBox 4.0.4	2011-03-03T18:48:31Z	2011-03-03T19:08:39Z	2011-03-03T19:08:39Z	"According to the [http://www.virtualbox.org/manual/ch05.html#hdimagewrites VirtualBox] docs:
  ''Technically, a ""multiattach"" image behaves identically to an ""immutable"" image '''except the differencing image is not reset every time the machine starts'''.''

This doesn't appear to be the case.

I created a VM with a dynamically sized disk, installed Win7, sysprepped the VM and shut it down. I released the HDD and used '''VBOXMANAGE MODIFYHD ... -TYPE MULTIATTACH''' to mark this HDD as immutable and that children should not auto-reset.

I then created a new VM, using the base HD which created a differencing disk for its own data.

Using '''VBOXMANAGE SHOWHDINFO ...''', I examined the new VM's differencing disk and saw that it claims auto-reset is on.

I booted the new machine, completed the OOBE (Out Of Box Experience) and modified the desktop wallpaper. I shut down the VM and then rebooted it and was sent straight back to the OOBE again.

VirtualBox is a great product, but its poor handling of differencing disks, requiring users to delve around in the command-line tools to configure even the most rudumentary differencing scenarios, is, in my opinion, VirtualBox' biggest weakness, especially when compared to Hyper-V and VMWare.

Virtualbox Guest: Windows 2003 Standard

If I am connected to both the Virtualbox Host and Virtualbox Guest via RDP the clipboard fails to work.  Also it looks like it locks up the local application that I am copying from. 

For example If I copy something from either Excel or notepad and I want to past it into notepad on the VirtualBox host or any Windows Virtualbox Guest, the paste will not work and the source app will be locked until I either disconnect either the RDP connection to the VirtualBox Host or VirtualBox Guest.

If a RDP connection is open to only the VBOX Guest or VBOX Host it works fine.

If the guest edition is removed, a restore can be made.

Comments on the net suggest that this might be due to the path names of the vboxservice in the registry. However a brief examination of the service keys did not show anything unusual to my eye.

Jedoch wird bei dem ""Durchsuchen""-Dialog bei Virtual Box nur der Path-String ausgelesen und als lokale Adresse behandelt. Somit erkennt Windows nicht, dass es nötig ist, ein Fenster zu erstellen um die Zugangsdaten (Benutzername, passwort) eingeben zu können.

Jedoch könnte man die Funktion von Virtual Box umschreiben. So dass man da bei dem Fenster ""Gemeinsame Ordner"" gleich die Zugangsdaten mit angeben kann und diese dann entsprechend der Paramter-Syntax mit einer UNC-Connection Funktion übernommen werden.

So mit würde folgender Leistungs-Belastener Schritt nicht mehr nötig:

I have an XP guest (running on a Vista host, but I don't think the host platform matters). Let's call the XP guest GUEST1 and the Vista host HOST1. Often, using another plain standalone XP PC (not running VirtualBox) -- a separate physical PC on the same network that we'll call PC1 -- I will use Windows Remote Desktop from PC1 to access GUEST1 remotely. If I copy text in the Remote Desktop session from PC1, the next paste operation on HOST1 results in pasting the data that was copied from the Remote Desktop session on PC1 (obviously by way of GUEST1).

The data copied to the clipboard should have remained only on the physical PC on which is was copied, in this case PC1 which isn't even running VirtualBox.

This becomes a problem when a separate user on another computer is remotely accessing a guest. This is actually how I discovered the problem as undesirable data was appearing in my host clipboard while someone else was remotely accessing my guest. They could be copying sensitive data, which should not appear on the host clipboard.

This is an easy scenario to recreate on demand. I have verified that this scenario happens in 3.0.4 and as far back as 3.0.0, possibly earlier as I have been having unexpected data appear in my host clipboard for some time."	Christopher Makris
5816	Reserve the guest OS taskbar space on the host OS desktop in seamless mode	Windows		2009-12-21T08:23:27Z	2010-02-23T13:58:13Z	2010-02-23T13:58:13Z	"I think this will be useful for those who want the guest to work seamless with the host OS.

In the seamless mode, When a host application is maximized, it will cover the guest OS taskbar. If I want to use guest application, I have to minimize the host application to make the guest taskbar show up. So there will be a lot of unnecessary mouse clicks and movement, if I have to do much copy/paste work between guest and host.

Now, I walk around this problem using the HSI(Hawkeye ShellInit), a small tool that can create any number of margins on the screen that maximized windows won't cover.

I think this can be easily implimented in the Virtualbox. The guest additions gets the guest's taskbar position and width, then sends this imformation to the vboxmanager. The vboxmanager performs the same function in seamless mode like what the HSI will do. "	kidault

I.e.

A  <--Read only
|-B  <-- Read only
  |-C

Then delete snapshot B, when it tries to merge to give you A->C it'll fail, however the UI shows B missing now and you end up having to delete all snapshots and reverting back to the base disk.

If the merge operation fails then the snapshots in the UI should be left untouched."	Robert Garfoot

I just dug this out of the forums, realizing that after all this time; I've had it in the wrong spot.

I just bought a tablet (slate) WinCE pc with a 10"" resistive touch screen. I can connect to virtualbox with vrdp and it looks great, and the response times are great, but I have one issue. With the touchscreen, I have to touch twice to click (once to move the mouse to the desired location, again to click) or hold it for like a second. This makes double clicking impossible. Although, I can use the hard navigation buttons just fine. Using the Microsoft's RDP on the guest works perfect, so I am believed to it bieng virtualbox.

I am hoping to use the tablet for interacting with MS PowerPoint that is being displayed fullscreen on a projector simultaneously. It doesn't matter if mouse integration is enabled or not.

I have:
Host: win7 x64
--CPU: i7 920
--Memory: 6 Gb 
Network: Host - ethernet - wireless router - wifi (802.11g w/ excellent signal) - tablet
Guest: Win XP Pro Sp 2 tablet edition
--VB version: 3.0.8; additions: installed
--mouse integration: on and off
tablet: viewsonic v210 WinCE 4.2
--RDC v5.1 settings:
----Display: 256 color (lowered to see if it would help, didnt)
----Local resources: Sound: leave at remote; local dev: none checked
----Experience: Performance: Custom (none clicked, to test, didnt help)

3045	Feature Request: Control HOST os resolution in fullscreen mode (for res switching)	Windows	VirtualBox 2.1.0	2009-01-15T12:05:14Z	2009-10-29T19:35:02Z	2009-10-29T19:35:02Z	"Id like to see a feature that allows virtual box to control the physical monitor on resolution switching 

for example
  you launch gameA.exe and it needs to run in fullscreen 800x600 on the GUEST os but the HOST os is 1600x1600 (right now it just shows as a little square in the middle of the screen with big borders), it would be really nice if VirtualBox could change the HOST display to the required resolution the guest os is at. (this would probably be needed for windows only and when in fullscreen mode, i think X11 doesn't change res's as much) 

so far other software such as microsoft virtual pc 2007 (in their options it has a pulldown that says ""use guest os resolution"", ""use host's resolution"" ..etc)

vmware , and parallels has a option, VirtualBox is such great software this feature missing is a giant let down for me, it has speed, hardware support, lightweight, it just cant control the host's resolution. :\

dont confuse this with ctrl+g (since that just ups the virtualbox to the host's current resolution (what i need is the host's resolution to match the currnet guest os resolution so basically its reversed ;) )

When I move out of the affected areas, the regular mouse pointer appears. The other mouse pointers, like the hand pointer when selecting a hyperlink, and the hourglass pointers appear fine.

When I disable the mouse pointer integration, all pointers are working perfectly. However, I'd like to have the mouse pointer integration enabled as I would have difficulty moving from an application in my host and an application running in the guest (I have to hit Right-Ctrl every time.)

Using the same VirtualBox version on a Linux (Ubuntu Jaunty) host and the same Windows XP guest, I did not experience this problem.

Then try to go in to shared folders and remove it - this will appear to work successfully.  But if you go into the guest OS and browse, \VBOXSVR\mp3 will still be there!  Nothing you do within Vbox will make that change - rebooting, logging out as different user, etc.

WORKAROUND:
* Shut down the guest OS
* Go to MachineDisks and find the guest OS's .xml file.
* Find section SharedFolders/SharedFolder which corresponds to share you're trying to remove.
* Change or remove the entry to be correct.
* Restart guest OS virtual machine.
* Vbox appears to just remove the entry you modified in the .xml file regardless of whether you set it to a valid value or not.
