I've run into this problem too.  I ended up setting up a dhcp-relay on the dom0 and configured it to forward all requests to my dhcp server.  No problems after that.

I'm not entirely sure thats the "correct" way but it worked for me.  If anyone has any other suggestions, I would love to hear them.

I am running Xen 3.0.2 on a regular Intel P4, with the default network
setup.  My problem is that my domU's DHCP requests do not seem to reach
the outside world.   I can see them if I tcpdump in dom0 on xenbr0, but
I cannot see them from another machine plugged into the same switch as
my Xen machine.  This external machine _can_ see the DHCP requests made
when dom0 makes its initial requests.  I can't think of anything that
might cause this.

Any ideas?
