[Qemu-devel] [Bug 1135567] [NEW] QXL crashes a Windows 7 guest if host goes into screensaver

[Philosophish]

Public bug reported:

Note: if further information is required, I'll be glad to supply it.

I am using on the host
- HP z800 with 72GB RAM and 2x x5680
- Gentoo 64-bit host (3.7.9 kernel, FGLRX RADEON driver 13.1)
- LIBVIRT 1.0.2 with QEMU(-KVM) 1.4.0

The guest:
- Windows 7 32-bit
- 2GB allocated
- 2 CPU
- using virtio for everything (disk,net,memballoon)
- Display = SPICE with spice channel
- Video driver is qxl (ram says 64MB)
- Spice-guest-tools 0.52 installed

When I use QXL and  have the guest open in Virt-Manager/Virt-Viewer and
let the host go into screensaver mode, the Win7 crashes hard.

When I change video to VGA, it survives the screen saver,  no problem at
all ,smooth sailing.

regards
