Interesting, I would follow the packet to see how far it goes.
The DHCP packets should follow this path:
Guest's eth0 <-> tap <-> Host's eth0 <-> Dhcp service.
So, attach the tcpdump to the tap interface, you should see the
DHCP request passing and maybe the DHCP reply. Then do the same
on host's eth0. If needed, on guest's eth0 too.
