Hi Serge, Yes I confirm it did fail. I am using the "Virtual Machine Manager" and when I enable the network it gives me the message I posted earlier.
When I sun it at the command line, (after updating my libvirt deb today from your ppa) I get: ademaria@ademaria-laptop:~$ sudo virsh net-start default error: Failed to start network default error: internal error '/sbin/iptables --table mangle --delete POSTROUTING --out-interface virbr0 --protocol udp --destination-port 68 --jump CHECKSUM --checksum-fill' exited with non-zero status 2 and signal 0: iptables v1.4.4: unknown option `--checksum-fill' Try `iptables -h' or 'iptables --help' for more information. In both cases, it does not look like just a warning to me, as the network does not start. Please let me know how can I assist more.
