Before I post to networking-discuss I wanted to ask if anyone had
tried this on this:
I'm trying to run a dhcp-server on a dom0 over a vnic so that the
domU's can get IP addresses.
I created a vnic r1 over e1000g0 and gave it a static IP
172.0.94.111/24 so I can run the dhcp server over this vnic.

When I bring up my domU I see the DHCPDISCOVER request in the domO but
the dhcpserver is not issuing IP address.

Any suggestions or obvious thing that seems to be wrong it this setup?
