#7970 obsolete Random BSOD with culprit VBoxUSBMon.sys jkirk
Description

My system unexpectedly reboots at random times, sometimes within the first minute i boot a vm, sometimes after hours. But always when virualbox is open. Then i used driver verifier tool on windows 7 to track all the related Oracle drivers. Windbg sometimes says the culprit was Process Explorer, sometimes says VBoxUSBMon. I have attached the small dump for both cases. I also have the kernel memory dumps for these cases, just in case. In all of the cases, the guest machines were Windows (either XP or Win7) but not sure if it has something to do with the problem because of the random nature of the case.

#7973 obsolete Desktop not displayed properly in fullscreen with 3d acceleration andrew.edmunds
Description

Host configuration:

  • Lenovo T61 laptop
  • Mobile Intel 965 Express display adapter
  • Display adapter driver version 6.14.10.5218
  • Windows XP SP3
  • VirtualBox 4.0.0 PUEL

Guest configuration:

  • Ubuntu 10.10 (Maverick)
  • 3D Acceleration enabled

In fullscreen mode with 3D acceleration enabled, the desktop is not displayed properly. See attached screenshot. It looks as though each guest window is being drawn as a reduced copy of the entire desktop.

I can successfully show fullscreen video in the guest with mplayer. Switching the guest in and out of fullscreen mode with the video running also works correctly. So it seems to be only some behaviour of compiz that is not handled properly.

The desktop is displayed OK in windowed mode wtih the VirtualBox window selected. When another window on the host desktop is selected it is noticeable that the guest display is slow to repaint after being uncovered. Sometimes repainting fails completely. Possibly this is a separate issue but for now I have assumed that they are two symptoms of a single problem.

No problems are evident with 3D acceleration disabled.
