##### 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.

貢獻指南
研究方向
先檢查 CentOS 7.9 agent 上的 LibvirtComputingResource 日誌項目和 security_group.py 命令,然後在 CloudStack 4.18.1.0 上重現執行個體建立流程,同時比較失敗日誌和預期日誌。完成的標準是安全性群組規則已套用至執行個體,且回報的 iptables 錯誤不再發生。
