I don't run DHCP on dom0 (are you using XEN?)  for this very reason. I
don't want DHCP broadcasts all over the network, and don't want the
domU's to accept DHCP requests from other hosts.

DHCP *normally* logs to /var/log/messages, unless you configured it otherwise.

try "grep dhcp /var/log/messages"

OR "tail -f /var/log/messages" and then "service network restart" on a
domU to see if it shows anything on dom0. Can the domU's get their IP
from another server? Try en eliminate this altogether.
