Hm, that's a little odd. As far as I know, KVM migration isn't supported yet. There are some patches from Rich Jones (that he's posted a few times), but there is a bug in upstream KVM that prevents them from working properly. Unfortunately, upstream KVM/Qemu have decided to re-do their implementation of migration, so we can't commit to Rich Jones' patches until that gets sorted upstream. Chris Lalancette

Well, no. It gets complicated :). Since migration is one of the important features of ovirt, we are basically carrying a custom kvm and libvirt patch so that migration *does* work in ovirt. The problem is, we can't carry that patch forever, and we can't commit to it for libvirt either. For what it's worth, I don't expect that it will take long to resolve this upstream; once KVM gets it sorted, we will dump ovirt's custom patches, get Rich's patches into libvirt, and be all upstream then.
