Hi,
Please see the below discussion with the spice community.
libvirt is adding a parameter about video ram to qemu process and this parameter might be responsible of a crash in the qxl at higher resolutions. Spice people tell me that their default ram should be 64 Mbytes.
I'm using libvirt 0.9.0 and qemu 0.14, virt-manager 0.8.7. When configuring a guest in virt-manager, cirrus driver is added as default, then you can change it to qxl, but the 9 MB videoram parameter can't be adjusted and it does not automatically change to 64 MB. If you add a 2nd qxl video card, then it has 64 MB memory.
The parameter that qemu gets with one qxl device is:
-vga qxl -global qxl-vga.vram_size=9437184
The parameter that qemu gets with a second qxl device is:
-vga qxl -global qxl-vga.vram_size=9437184 -device qxl,id=video1,vram_size=67108864,bus=pci.0,addr=0x8
Is this a bug in libvirt or other related tools?
libvirt allows arbitrary RAM specification for QXL, so I think it is probably a virt-manager issue. When changing the display type from cirrus -> qxl, virt-manager should probably just remove any RAM attribute in the XML and let libvirt re-assign the default setting
Fixed in virt-manager now: http://git.fedorahosted.org/git?p=virt-manager.git;a=commit;h=7a8a35e564b8c4... Thanks, Cole
