[fedora-virt] spice/qxl resolution setting?

[Tom Horsley]

I just installed a centos 6.5 virtual machine on my fedora 20 host.

It works fine with spice/qxl, but insists it should come up
in 1024x768 resolution.

I can use the Display setting app inside centos to change
the resolution to something more reasonable like 1600x900,
but if I log off or reboot, it is back to 1024x768 again.

Any way I can convince the virtual machine that the default
resolution is 1600x900? My Windows KVM has no problem
remembering the resolution I set in it.
