Here is my compute worker's iptables rule (Ubuntu 12.04):
$ sudo iptables -S -t mangle -A POSTROUTING -o virbr0 -p udp -m udp --dport 68 -j CHECKSUM --checksum-fill
And I change it to: -A POSTROUTING -p udp -m udp --dport 68 -j CHECKSUM --checksum-fill
than my ubuntu guest can get dhcp ip correctly.
