> I have CloudStack 3.0.4 with a Basic Zone defined. The Zone includes several KVM hosts and uses Security Groups (in other words, IPtables on the hosts) to isolate traffic between VMs.
> The problem: if, for some reason, IPtables on the host are flushed or the iptables service is restarted, the cloud-agent doesn't pull the correct rules from the management server and doesn't synchronize the host with Security Groups definitions in CloudStack. Restart of the cloud-agent service doesn't help as well.
> Shouldn't the agent do it?
