前提
AOS 6.10
AHV 2023.～
クローン元のVM名：RockyLinux9.5
クローン後のVM名：RockyLinux9.5-2
クローン元のVMのNGAの確認
クローン元のVMでNutanix Guest Agentが動作しているか確認します。
systemctl status ngt_guest_agent
出力例
[root@RockyLinux9 ~]# systemctl status ngt_guest_agent ● ngt_guest_agent.service - Starts, stops Nutanix Guest Agent.

runnningとなっていることから、Nutanix Guest Agentが動作していることを確認できました。
クローン後のVMのNGAの確認
Nutanix Guest Agentの起動状況
Nutanix Guest Agentのスタータスを確認してみます。
systemctl status ngt_guest_agent
出力例
[root@RockyLinux9.5-2 ~]# systemctl status ngt_guest_agent ● ngt_guest_agent.service - Starts, stops Nutanix Guest Agent.

このように、サービスとして起動していることを確認できました。
どうやら、Nutanix Guest Agentは起動時に自動的に有効化されるように設定されているようです。
[root@RockyLinux9.5-2 ~]# systemctl is-enabled ngt_guest_agent Enabled
CVMとNGA間の通信確認
次のコマンドを使用して確認できます。

本来は、次のように、引数で指定したVMに関する情報が出力されますが、クローンしたVMでは出力されません。CVMとNutanix Guest Agentで通信が出来ていないことを確認できました。

}対処方法
Nutanix Guest Agentが正常に稼働していることは確認できました。
クローン後のVMでNutanix Guest AgentがCVMと通信できるようにするにはNutanix Guest Toolをマウントします。
マウントされていることを確認します。
再度、CVMとの通信が正常にできているか確認してみると、先ほどとは異なり、VMの詳細情報まで確認することができました。
