| #10283 | obsolete | VirtualBox on Windows does not shutdown if serial port is busy | ||
| Description |
Host: Windows XP, 2GB RAM, Virtualbox 4.1.8 with extensions 4.1.8 installed Guest: Ubuntu 10.04.3, 1GB RAM with guest additions installed Problem summary: Guest won't shut down normally when serial COM port is actively receiving data A microprocessor-based device is attached to the host COM1 port via RS-232. My application (a C-language program) is running on the guest OS which has the virtualized serial port (via Port 1, Enabled, Port number COM1, Port mode Host Device, Port/File Path: COM1:) open at the time I want to shut the system down. The application program is started via /etc/init.d/rc.local and is run in NOHUP (that is, nohup sh (some script)). My program does not have any provision to monitor for signals (to shutdown gracefully via external signal). There is no adverse consequence to my application environment for an uncontrolled shutdown. The application program sends a poll message about once a minute, after an initial delay of about a minute. The external microprocessor-based device sends a response multiple times per second, regardless of whether a poll is received or not. This means once my program starts and opens the serial port, it will immediately be receiving data from the external device, regardless of when my program sends a poll. When the external device is disconnected (so that the polls are being sent, but no responses are being received), the Ubuntu 10.04.3 guest can be shutdown (via the shutdown button on the Ubuntu menu bar) repeatably without difficulty. When the external device is connected (so that responses are being received), the Ubuntu 10.04.3 guest USUALLY (but not absolutely always) will not shutdown using the same (shutdown button) procedure. When it fails to shutdown, I try to close the Guest window with the windows close button, but that does not respond (I don't see a Virtualbox dialog box offering ACPI shutdown, power-off, etc.) I can only force the window to close with the Windows taskmanager, and it only closes after a short (maybe 30 second) delay. I get another dialog box offering to send a problem report to microsoft (I dismiss that dialog.) As I wish to provide my application and virtual machine to a colleague for field demo, this shutdown issue is of consequence. Two log files (each with a single session) are attached, one reflecting the failed shutdown process (serial device attached/sending), the other reflecting a normal shutdown process (serial device unattached).

| #10285 | obsolete | USB connection error (Failed to create a proxy device) | ||
| Description |
I have a cheap USB Stick which cannot be connected to the Virtual Machine (I checked this problem on Host system Ubuntu 11.04 (amd64) and 11.10 (i386) ). All other USB sticks work fine. Problem sounds like existing bugs (i.e. #10131) but these bugs are in combination with Windows Host system. But I have a Linux host systems, which works concerning USB support normally much more stable than Windows host systems. The USB-stick itself works fine on Windows and Linux Machines. If it helps, I can send you the USB stick for further tests. I have made some read out, take a look into the attached text file. This is the message, shown in the Virtual Machine when I am trying to connect the stick. Das USB-Gerät usd disk [0100] konnte nicht an die virtuelle Maschine vm-WinXP-technik gebunden werden. Failed to create a proxy device for the USB device. (Error: VERR_READ_ERROR). Fehlercode:NS_ERROR_FAILURE (0x80004005) Komponente:Console Interface:IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb} |

| #10287 | obsolete | Screen space | ||
| Description |
Laptops today have less "lines" then a couple of years ago. Typically 1600x1000 has become 1600x900. Visible vertical space is limited. The VirtualBox menu bar (not Mini menu i seemless mode) in a VM colud be moved into the OS window main title bar as a popup (right click) menu, to give more screen space to the guest. And/or the OS window title bar could be replaced with a mini bar like solution, displayed only when touched, freeing up even more vertical space. The VirtualBox status bar could be hidden in many normal working situations. Incorporating the status bar/icons into the main menu may be a good solution. A View option to hide/show the status bar, is anaother way to handle this. |
