[Cialug] Xen ducp mystery

CHanged a xen machine from dhcp to static last week (which is not a simple
process in itself), .. after finally getting it running I saw a bogus dhcp
IP on my netbook. Chalking it up to a well-used config, I assigned one
manually and focused on getting the system up and running.

Now, *other* machines on the network are getting bogus dhcp addresses, and
I suspect that libvirt is still giving them out. No dhcp* daemons are
running, however, . and the leaes messages in the logs stopped at the
point that I had switched to static IPs; scanning with nmap does not
identify any dhcp services being offered on the host or guest.

Question - is there any chance libvirt is giving out dhcp addresses
without any of the usual evidence (i.e. daemon, logs, open port)?

	TIA,
