操作方法2015/01/16 |
virsh コマンドを使った仮想マシンの操作方法です。
|
|
[1] | 仮想マシンの起動 |
[root@dlp ~]# virsh start www # 仮想マシン'www'を起動
Domain www started
[root@dlp ~]# virsh start www --console # 仮想マシン'www'を起動し同時にコンソールに接続 Domain www started Connected to domain www |
[2] | 仮想マシンの停止 |
[root@dlp ~]# virsh shutdown www # 仮想マシン'www'を停止 ( ゲスト側で「acpid」が動作している必要がある )
Domain www is being shutdown
[root@dlp ~]# virsh destroy www # 仮想マシン'www'を強制停止 Domain www destroyed |
[3] | 仮想マシンの自動起動設定 |
[root@dlp ~]# virsh autostart www # 仮想マシン'www'をシステム起動時に自動起動
Domain www marked as autostarted
[root@dlp ~]# virsh autostart --disable www # 仮想マシン'www'の自動起動設定解除 Domain www unmarked as autostarted |
[4] | 仮想マシンの一覧を表示 |
[root@dlp ~]# virsh list # 稼動中の仮想マシンを一覧表示 Id Name State ------------------------------------------
2 win2k8 running
[root@dlp ~]# virsh list --all # 全ての仮想マシンを一覧表示 Id Name State ------------------------------------------ 2 win2k8 running 1 www shut off |
[5] | コンソールの切り替え ゲストOS側からホストOS側へのコンソールの切り替えは Ctrl + ] キーです。 ホストOS側からゲストOS側へのコンソールの切り替えは 「virsh console (ゲストの名前)」とコマンドをうちます。 |
[root@dlp ~]# virsh console www # 'www'のコンソールに接続 Connected to domain www
Escape character is ^]
CentOS release 5.11 (Final)# Enterキー
Kernel 2.6.18-398.el5 on an x86_64

Password:# ゲスト側に切り替わった Last login: Thu Nov 4 12:33:37 on ttyS0 [root@www ~]# # Ctrl + ] キーを押す [root@dlp ~]# # ホスト側に切り替わった |
[6] | その他の操作です。たくさんあるのでいろいろ試してみてください。 |
[root@dlp ~]# virsh --help
