Sorry my configuration in the first email was - dom0+ dhcpserver(dom0
running a DHCP-server) that is why you see e1000g0 as well along with
the r1 (vnic interface).
However in my new configuration i.e dom0+ UC-dhcp (dhcpserver domU
running a DHCP-server) + UC-web (domU trying to obtain an IP address
via dhcp)
The issue I see is the domU UC-web doesn't get an IP address.
Here is what I have:

Sagun, I'm confused about your configuration. You say:
On system A the setup I have is:
dom0+ dhcpserver(domU running a DHCP-server) + dhcpclientA (domU
tryng
to obtain an IP address via dhcp)
Yet your in.dhcpd invocation mentions e1000g0:
r...@lm2-dom0:~# /usr/lib/inet/in.dhcpd -dv -i r1,e1000g0
The domU can't access e1000g0, so how can you be running in.dhcpd
there?
