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. -- Russ herrold
