Unfortunately, migration is not live migration ... a resource (the VM)
can't be live-migrated if it depends on another resource (the IP) that
If you modify IPaddr to be live-migrateable, it should work. It has to
support migrate_from and migrate_to actions, and advertise them in the
meta-data. It doesn't necessarily have to do anything different from
stop/start, as long as that meets your needs.
