basic operarions with virsh command.
|
|
| [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 is required to run on guest )
Domain www is being shutdown
[root@dlp ~]# virsh destroy www # force stop 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
|
| [5] | Switch console Move to GuestOS to HostOS with Ctrl + ] key. Move to HostOS to GuestOS with a command 'virsh console (name of virtual machine)'. |
|
[root@dlp ~]# virsh console www # connect to 'www' Connected to domain www
