Per the documentation, https://libvirt.org/migration.html#scenarionativedirect , 'virsh migrate domain dest interface' was a support command. As of 1.3.4 (when compression support was added), it's not. For example: # virsh migrate test qemu+ssh://10.0.0.1/system tcp://10.0.0.1/ error: invalid argument: Unsupported compression method 'tcp://10.0.0.1/' It seems like the compression code is grabbing the last argument now. Was this intentional? If so, what is the new command format? When will the documentation be updated?
