##### EXPECTED RESULTS

Here is an example where I created a machine on an agent node with a functioning security group. In this case, both the security group and iptables are working correctly, and there are no iptables errors reported.

##### ACTUAL RESULTS

Commencez par les entrées de journal de LibvirtComputingResource et les commandes de security_group.py sur un agent CentOS 7.9, puis reproduisez la création d’une instance sur CloudStack 4.18.1.0 en comparant les journaux en échec et ceux attendus. C’est terminé lorsque les règles du groupe de sécurité sont appliquées à l’instance et que les erreurs iptables signalées ne se produisent plus.
