Migration is client-driven: libvirt sends the VM's memory to the destination's own host name unless a migration URI is given, and the app never gave one. Where the hosts cannot resolve each other's names (or the names point at a management network) every migration failed with "Unable to resolve address '<host name>' service '49152'". A compute now has an optional migration address (an IP address or a host name, no scheme or port), editable in the compute form and the API. A VM migrating to that compute is sent to tcp://<address> (bracketed for IPv6). Empty, the default for existing computes, keeps the previous behavior. The compute's host name is not reused, because for SSH computes it can be an ssh_config alias. The migration log entry names the address when one is set.
