At this point, the only NBD server type virt-p2v supports is nbdkit with
socket activation; therefore, outputting "localhost" from
start_nbd_server(), and tracking it via variables / parameters from there
on is needless generality. Remove the affected variables and parameters,
such as "ipaddr", "hostname", and "nbd_local_ipaddr".
