only in tcpdump?
My setup is:
firewall accepting udp traffic from 67:68 ports
selinux disabled
host.allow empty
tcpdump showing checksum errors
but just right now I solve my problem was the tx offload performed
by the network card

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?
