Yes it is supported in KVM >= 79, or QEMU >= 0.10.0 and libvirt 0.6.0

Earlier versions of KVM/QEMU have problems preventing it from working.

ALso note that successful migration depends on the hardware config of
your guest. In theory any config should work, but in practice there
have been bugs in the device state save/restore process of various
types of device. So test your particular VM config successfully
migrates before relying on it in production.

Unfortunately that page is a little out of date. Seems we should make a
rule that this page be one of the things we update as part of the release
