If you go back over the list you'll see that I wrote a patch for KVM
migration, which was enhanced by Chris Lalancette, but currently this
is on hold while KVM decide how they are going to (re-)implement
migration.  There was a big patch posted to the KVM list on Sep 9, but
I'm not sure how much of it went in.

In any case, unless you want to use the unofficial patches (which will
almost certainly not interoperate with future official versions of
libvirt/libvirtd) you can only wait or get involved with KVM.
