Maybe for the future we should consider always building a manual migrate
URI in virsh.c (or maybe libvirt.c), using the destination connection
URI hostname. This is what we do in virt-manager, since it's really it
gives the closest guarantee for success.
Yeah, to be perfectly frank, the fact that the destination of the migration
tells us the hostname to migrate to is actually a design bug in the live
migration protocol. I tried to do something like you suggest, but I
couldn't come up with a way that would support both old and new clients
and servers and not be qemu-specific. For now, I think this is the best
we can do. I think the correct answer in the medium to long term is to
make tunnelled migration the default, since we are already certain that
the libvirt control channel works.
