This is the basic Operarions with virsh command.
|
|
| [1] | Start Virtual Machine |
|
# start Virtual Machine 'ubuntu' root@dlp:~# virsh start ubuntu Domain ubuntu started
# start and connect to console of 'ubuntu' root@dlp:~# virsh start ubuntu --console Domain ubuntu started Connected to domain ubuntu |
| [2] | Stop Virtual Machine |
|
# stop Virtual Machine 'ubuntu' root@dlp:~# virsh shutdown ubuntu Domain ubuntu is being shutdown
# stop fourcely Virtual Machine 'ubuntu' root@dlp:~# virsh destroy ubuntu Domain ubuntu destroyed |
| [3] | Set auto-start for Virtual Machines |
|
# enable auto-start for 'ubuntu' root@dlp:~# virsh autostart ubuntu Domain ubuntu marked as autostarted
# disable auto-start for 'ubuntu' root@dlp:~# virsh autostart --disable ubuntu Domain ubuntu unmarked as autostarted |
| [4] | List all Virtual Machines |
|
# list all active Virtual Machines root@dlp:~# virsh list Id Name State ------------------------------------------ 2 win2k12R2
running # list all Virtual Machines include inactives root@dlp:~# virsh list --all Id Name State ------------------------------------------ 2 win2k12R2 running 1 ubuntu 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 ubuntu # connect to 'ubuntu'
Connected to domain ubuntu
Escape character is ^] # Enter
Ubuntu 15.04 ubuntu ttyS0
