kvm, failed to start network default in virsh

xxx@yyy:~$ virsh net-start default
error: Failed to start network default
error: internal error '/sbin/iptables --table filter --delete INPUT --in-interface virbr0 --protocol udp --destination-port 69 --jump ACCEPT' exited with non-zero status 1 and signal 0: iptables: Bad rule (does a matching rule exist in that chain?).

Dec 27 23:15:39 yyy libvirtd: 23:15:39.512: warning : networkAddIptablesRules:851 : May need to update iptables package & kernel to support CHECKSUM rule.

and there is no virbr0 interface.
