[libvirt-users] Recreating nwfilter rules without a restart

[Brian Rak]

Let's say I have some iptables rules defined to restrict guest traffic.  
If I restart the hosts firewall 'service iptables restart', all the 
guest-specific rules get blown away.

Is there a way to reapply all the guest firewall rules, without 
restarting each individual guest?

It looks like if I edit a nwfilter with `virsh nwfilter-edit` it goes 
and reapplies the rules to all the guests, so this functionality seems 
to be present already.
