Are they on the same network or clan? Is the firewall or host.allow file blocking you or maybe selinux? Is it a windows machine trying to get the address or linux? Do you see anything in the logs or only in tcpdump?

I mean, it seems working because the dhcpd log shows that the requests
are coming from the domU but the domU doesn't get the DHCPD answare.
I also read about setting off ethernet tx offload under dom0 via "ethtool -K eth0 tx off"
but it seems not helping to solve anything, at least in my case.
Which kind of configuration you made in your side?
