| [1] | Start Virtual Machine |
|
[root@dlp ~]# virsh start www # start Virtual Machine 'www' Domain www started
[root@dlp ~]# virsh start www --console # start and connect to console of 'www' Domain www started Connected to domain www |
| [2] | Stop Virtual Machine |
|
[root@dlp ~]# virsh shutdown www # stop Virtual Machine 'www' ( 'acpid' needs to be running on a guest ) Domain www is being shutdown
[root@dlp ~]# virsh destroy www # stop fourcely Virtual Machine 'www' Domain www destroyed |
| [3] | Set auto-start for Virtual Machines |
|
[root@dlp ~]# virsh autostart www # enable auto-start for 'www' Domain www marked as autostarted
[root@dlp ~]# virsh autostart --disable www # disable auto-start for 'www' Domain www unmarked as autostarted |
| [4] | List all Virtual Machines |
|
[root@dlp ~]# virsh list # list all active Virtual Machines Id Name State ------------------------------------------ 2 win2k8
[root@dlp ~]# running virsh list --all # list all Virtual Machines include inactives Id Name State ------------------------------------------ 2 win2k8 running 1 www shut off
