Ticket #10341 (closed defect: fixed)
Guru Meditation -2701 (VERR_VMM_RING0_ASSERTION) Windows 7 x64 Guest on Linux 64-bit host
|Reported by:||wnicholls||Owned by:|
Host computer: M51S lapop (core2duo, NVidia adaptor) running Ubuntu 11.10 (oneiric) 64-bit; 4GB RAM. 3.0.0-15-generic #26-Ubuntu SMP. Virtualbox 4.1.10 Guest: Windows 7 SP1 64-bit, 2GB RAM allocated, 256MB video RAM. VirtualBox Guest Additions 4.1.10 (more on this later). Also similar problems with Guest Windows XP 32bit, 512MB RAM, not sure of which guest additions version but probably 4.1.10).
These problems started about a month ago when VB 4.1.8 was current. However this exact report (today) is as above.
This maybe same ultimate issue as #10331 but I'm reporting as separate ticket because his/her problem went away with removing 3D whereas mine didn't.
This exact report; If I read the log correctly, the Guest VM crashed with error (first recorded in log Guru Meditation -2701 (VERR_VMM_RING0_ASSERTION)) after 15 hours of operation - it was IDLE at the time, in fact I was not even home at the time! Several programs open, I attach screenshot as there is nothing incriminating or confidential in it .. you can see it was running in full-screen mode and a command window was in the foreground, with Visual Studio 2010 (and probably SQL Management Studio) running as well. Possibly a few other programs but generally lightly loaded. (attached VBox.log and VBox.png from the Windows 7 VM)
The history: I have been having problems with this VM locking up when closing the virtualbox window (normally get the savestate/send shutdown/poweroff dialog when I do this). No repaints. I've had windows in the guest lock up and become unkillable zombie processes. To the point where killall VirtualBox is the only way to get things closed. However as far as I remember the host OS is always ok. (I may have restored to reboot at some point for another reason to see if it did voodoo)
Also this VM did have troubles installing 3D video support this MAY be related. (See below).
NOTE: I have also had trouble at least once with another Windows XP VM locking up (but as I don't use that for regular work, tests only, I can't really give a decent history on that one. The Vbox.log has rotated out so it was more than 4 sessions ago) That does suggest a VirtualBox host-related problem NOT the VM itself!
Now - Guest Additions installer has been complaining "invalid DirectX installation detected" for the last few times, usually I ignore. However this time I uninstalled guest additions, uninstalled "Virtualbox graphics adaptor" through multiple iterations until I got back to standard VGA. Rebooted into safe mode, restored d3d8.dll and d3d9.dll and deleted every VBox*.* copy I can find ... in short just about everything suggested in the thread https://forums.virtualbox.org/viewtopic.php?f=2&t=46869 carefully!) And then reinstalled guest additions 4.1.10 with 3d support carefully turned off.
I also temporarily booted the host under 3.0.0-15 kernel but no joy there.
Only thing I have not yet tried is changing VM settings to less available RAM, as I had recently increased from 1GB to 2GB - loath to do this but it is something to try. As this last crash is about the tenth time this week, I guess I should try anything.
So - nothing above has fixed anything, may even have made it worse. Also as before, I suspect anything guest-related (3D support, guest additions, RAM size etc) is irrelevant but I tell anyway.
Hope all that long story helps. And PLEASE HELP. I have lost many hours of work here, almost ready to give up and purchase VMWare - seriously!
