#3797 fixed VBoxManage openmedium reports failure on connecting disk images but does it, however fails setting type as immutable => Fixed in SVN Roberto Muscedere
Description

I'm modifying a script which I have used for VirtualBox 1.6.x to setup a virtual machine for an educational lab. In migrating to 2.2.0 I've noticed some problems. Although I have a work around, it still should be addressed. To show how this error is reproduced I will show a series of simple VBoxManage commands:

  1. Create a VDI disk image (/tmp/a.vdi) - guest OS independent:
    VBoxManage createhd --filename /tmp/a.vdi --size 100 --format vdi --variant standard --type normal
    
    0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%
    Disk image created. UUID: fc46a7ef-cf54-487e-ab18-71e65c72077a
    
  1. To show that this is not an issue of re-attaching an already attached image, I will purge the VBox database
    rm ~/.VirtualBox
    
  2. Attach the disk image:
    VBoxManage openmedium disk /tmp/a.vdi
    

The following is the output from the command:

ERROR: Cannot register the hard disk '/tmp/a.vdi'
   with UUID {4c8fb9c9-5300-4d14-a9e5-c28c08cc347c} because a hard disk '/tmp/a.vdi'
   with UUID {4c8fb9c9-5300-4d14-a9e5-c28c08cc347c} already exists in the media registry
   ('/root/.VirtualBox/VirtualBox.xml')
Details: code NS_ERROR_INVALID_ARG (0x80070057), component VirtualBox, interface IVirtualBox,
   callee nsISupports
Context: "OpenHardDisk(Bstr(Filename), AccessMode_ReadWrite, hardDisk.asOutParam())"
   at line 1286 of file VBoxManageDisk.cpp

As you can see the system is stating the image is already in the database, but the database is not there to begin with. Fortunately, the image is registered as it appears in the ~/.VirtualBox/VirtualBox.xml file.

VBoxManage showhdinfo /tmp/a.vdi

UUID:                 fc46a7ef-cf54-487e-ab18-71e65c72077a
Accessible:           yes
Logical size:         100 MBytes
Current size on disk: 0 MBytes
Type:                 normal (base)
Storage format:       VDI
Location:             /tmp/a.vdi

However, if I try to use the option "--type immutable" with the "openmedium" command, the image does not become immutable and the error is still reported.

There is a workaround: we can use "VBoxManage modifyhd" to make it immutable:

VBoxManage modifyhd /tmp/a.vdi --type immutable

VBoxManage showhdinfo /tmp/a.vdi

UUID:                 fc46a7ef-cf54-487e-ab18-71e65c72077a
Accessible:           yes
Logical size:         100 MBytes
Current size on disk: 0 MBytes
Type:                 immutable
Storage format:       VDI
Location:             /tmp/a.vdi
#3798 fixed Incorrect syntax in mouseover text for Network Settings dialog -> Fixed in SVN Dan Davis
Description

Mouseover text for "Attached to:" dropdown of Network Settings dialog is broken English: "Controls the way how this virtual adapter is attached...." Should read "Controls how this..." or "Controls the way this..."

Trivial but non-professional and annoying. Screen shot attached.

#3799 fixed Audio output stops working on Linux guest Matt Kassawara
Description

I'm running VirtualBox 2.2.0 on a 64-bit Debian 5.0 (Lenny) host with 32-bit Ubuntu 8.10 (Intrepid) and Windows XP guests. I configured AC97 virtual sound devices on both guests using ALSA because PulseAudio can't find the correct output on my particular variant of Intel HDA hardware (Dell Optiplex 755). Sound initially functions great on both guests but audio output stops working on Ubuntu after a random amount of time (typically a couple of days) with no errors. Media applications still seem to recognize and use the sound device, but I can't hear anything. Restarting the Ubuntu guest temporarily fixes the problem. The Windows guest doesn't have this issue.
