They *say* they do, but in actual fact they don't work very well at all.

Try running virsh without Xen and all you get is "error: no valid
connection" when you try to do anything!

virt-manager works after a fashion, but gives errors galore, crashes
and a generated guest won't even boot off a valid .ISO file that
qemu-kvm had no trouble with. Even after using qemu-kvm to install the
guest, virt-manager still won't work properly. The resulting guest
won't connect to the external network, the mouse is terribly sticky,
and the manager refuses to reconnect to a running guest. All-in-all,
it's a bit of bad news if you're not running Xen.
