Just have them running, or using the virt-viewer and virt-manager
to look at them as well?

May be the same problem I'm having here:

https://bugzilla.redhat.com/show_bug.cgi?id=541387

Many things would freeze my display, but virt-viewer seemed to
provoke it much more frequently. I've now switched from radeon
to radeonhd and disabled many video accelerations with options
in the xorg.conf file and I haven't crashed in a long time.
Here's the relevant bit of my xorg.conf:

Section "Device"
	Identifier  "Videocard0"
	Option      "DRI" "off"
	Option      "AccelMethod" "shadowfb"
	Option      "NoRandr"
	Option      "UnverifiedFeatures" "off"
	Driver      "radeonhd"
EndSection

I also have to specify nomodeset on the kernel options
in grub.conf.
