[Spice-devel] qxl driver oom kills X server

[Andres Heinloo]

Hi,

after upgrading from openSUSE 12.2 to 13.2, I have exactly the same 
problem described here:

https://bugzilla.redhat.com/show_bug.cgi?id=1033663

Surfaces, image cache and fallback cache are currently all disabled 
(surfaces never worked anyway).

I boot the guest with 'nomodeset', because I haven't been able to use 
higher resolutions than 1920x1200 with the qxl modesetting driver. I 
need 2560x1600.

(There is no 2560x1600 in the EDID of the modesetting driver and adding 
a respective modeline in xorg.conf results in X server crash.)

My use case is that the terminal machine is runnig Spice client (spicy) 
full screen at 2560x1600.

When the X server within a VM crashes (as described at the link above), 
it is sometimes impossible to restart it (crashes again immediately). 
Rebooting the guest OS fixes this (restarting the QEMU process is not 
required).

Needless to say, these X crashes are extremely annoying. Any ideas to 
fix or work around this problem would be appreciated.

(As a possible workaround, I've been thinking about running Xspice 
within a VM to bypass the QEMU qxl device, although Xspice used to be 
less stable than qxl in the past.)

Thanks,
Andres.
