Found no handler for unit 'QGLVHWAData0' instance #0!

[Gregoo]

Hello :) .

I've posted on the forums (​http://forums.virtualbox.org/viewtopic.php?f=6), but nobody seems to know about it. Bugtracker search didn't give any result.

I'm assuming it hasn't been reported yet. Sorry if it's not the case o: .

Sometimes when I was resuming a saved machine, the GUI was silently crashing on VirtualBox 3.1 series (I don't know for 3.0 and earlier). After the crash the session was lost and the machine had to boot again from scratch. The crashes appear randomly I guess.

I think I had that bug only while powering the machine via Remote Desktop (not sure if it's related though). It crashed on Windows XP Professional x64, and it continued crashing on Windows 7 Professional x64.

Oh, the guest is a Windows Server 2003.

With the new VirtualBox 3.2, I had that message (Found no handler for unit 'QGLVHWAData0' instance #0! / VERR_SSM_INTEGRITY_UNIT_NOT_FOUND) when trying to resume a machine.

    00:00:05.506 Power up failed (vrc=VERR_SSM_INTEGRITY_UNIT_NOT_FOUND, rc=ERROR_SUCCESS (0X000000))

The machine didn't resume, but I didn't lose the saved state and no Windows message about the GUI crashing. When I tried to resume it a second time, the same message appeared and I received the Windows message telling me VirtualBox GUI had crashed.

No clue if it's the same error I had with VirtualBox 3.1 series.

There was those lines in the log o.o . Don't know if it's helpful though.

Anyways I've attached the log. No minidump sorry, I don't seem to have that feature enabled on my Windows 7.
