[Spice-devel] Questions regarding QXL drivers and Spice

[lucas.gary at gmail.com]

I've been attempting to use KVM / Spice and QXL to handle my virtualization
environment.

I've noticed a couple of issues, and I haven't been able to track down other
people having the same issues.

This strikes me as odd as I don't think my setup is particularly unique.

I'm running Fedora 15 with current versions of everything. (libvirtd 0.8.8)

The issues I've encountered are:
Windows Guests: (WinXp - Win 7)
Blue screen of death after doing something graphically intensive, I did find
a mention of this in bugzilla, but only one mention...

Linux guests (FC14 primarily but has occurred in other guests)
Random logouts that bounce me back to the KDE login screen.  It also resets
my resolution to something quite low.

If anyone is interested I can dig up memory dumps from the Windows XP
BSOD...  I was unable to find anything useful regarding the FC14 crashes but
I would be totally willing to attempt to reproduce them if it would help.

When these occur I am always running Spice + QXL...  Windows QXL client is
0.6.1, I just tried with 0.6.0, I didn't get a meaningful memory dump but
the process did eventually crash after about 15 minutes of scrolling
a Firefox browser up and down and watching flash videos...

I did manually change the ram setting in the XML file and here is the qemu
command line that launched the WinXP machine:
