We already have a migration URI, where you can specify the port: http://libvirt.org/migration.html#uris so working around the lack of encryption should be possible. The listen address can now also be specified if you don't want QEMU to listen on all interfaces: http://libvirt.org/html/libvirt-libvirt-domain.html#VIR_MIGRATE_PARAM_LISTEN_ADDRESS Jan
