I have a problem similar to this topic. I recently updated my kernel and changed some settings. I cannot remember anymore what I changed in particular but it was network / netfilter related.

Now when I try to start the default libvirt network it fails:

Code:
kiste ~ # virsh net-start default
error: Failed to start network default
error: Adding iptables rules to allow forwarding on 'virbr0' failed


/var/log/libvirt/libvirtd.log

Code:
error : networkAddMasqueradingFirewallRules:166 : Adding iptables rules to allow forwarding on 'virbr0' failed
error : virCommandWait:2376 : internal error: subprozess (/sbin/iptables -w --table filter --insert FORWARD --destination 192.168.122.0/24 --out-interface virbr0 --match conntrack --ctstate ESTABLISHED,RELATED --jump ACCEPT) ended unexpectedly status 1: iptables: Protocol wrong type for socket.


Google didn't help finding a solution and I also didn't find a list of requirements related to the kernel's network and filter settings. Is there such a list?

I'd be glad if someone can help me out. My kernel config is here: http://pastebin.com/QSqJApHb

Thanks
