The addition of a new private network segment seems like
overkill and needless additional fragility and complexity --
if one to one, use a remote syslog setup (viz., over UDP); if
one to many (domU), use a multicast sender and listeners.
Run either on the existing network seqment shared by the domUs
and dom0 already.
