VB crash on resuming from VB display put to sleep by guest
|Reported by:||meow9th||Owned by:|
|Version:||VirtualBox 4.2.4||Keywords:||crash display sleep|
Win 7 host, Xubuntu 12.04 guest
This crash is only 50% reproducible (based on 6 trials with the same settings).
What I did:
- Set guest to sleep display after 1 minute (Settings -> Power Management)
- Waited for guest to sleep display
- Moved mouse after VB display went blank
After step 3, I would either experience a 'VB has crashed' error from host (related to MSVCR100.dll), or guest would resume with no problems.
Attached are Windows logs with the VB crashes and VB logs.
Possibly relevant settings:
- VM has 3 displays, always run in fullscreen mode
- 3D acceleration enabled
I also played with the guest setting to switch the display off (instead of sleeping). Three trials yielded no crashes (although in one trial the guest display was screwed up; after redrawing it was fine).
I also briefly tested the host, having it sleep and turn off the display before the guest was set to do so. Only one trial each, no problem either time.
I think these crashes only started after I updated VB to 4.2.4. I have been using these settings for a very long time (a year?) and never had any problems until now.
My workaround is to set the guest to never sleeping or switching off the display.
