             Summary: CloudStack 3.0.4: firewall rules not restored on KVM host
                 Key: CLOUDSTACK-79
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-79
             Project: CloudStack
          Issue Type: Bug
          Components: KVM, Network Controller
    Affects Versions: pre-4.0.0
            Reporter: Vladimir Ostrovsky


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?
