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' ( require acpid in guestos ) 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 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
