KVM Command
##The command I used to create virtual machine
- Enter KVM GUI
virt-manager
- Enter command interface
virtsh
- Quit command interface
quit
- Start virtual machine
virsh start host-name & start host-name
eg: if the host-name is control-1 and you are in normal shell command interface, use command : virsh start control-1
if the host-name is control-1 and you are in KVM command interface, use command : start control-1
- Stop virtual machine
virsh stop host-name & virsh stop host-name
eg: if the host-name is control-1 and you are in normal shell command interface, use command : virsh shutdown control-1
if the host-name is control-1 and you are in KVM command interface, use command : shutdown control-1
- Make a snapshot of a virtual machine
snapshot-create-as domain-name create-snapshot-name
Before execute this command,Please make sure you have shutdown the virtual machine, if you haven’t shutdown this machine,
the created snapshot’s status is running.
the domain-name is the host name of your virtual machine, and the create-snapshot-name is the name your given to the created snapshot.
- See a KVM’s virtual machine list
virsh list & list
the list show all the domain of virtual machine.
- See virtual machine’s snapshot
virsh snapshot-list host-name & snapshot-list host-name
- Delete a snapshot of a virtual machine
virsh snapshot-delete host-name snapshot-name & snapshot-delete host-name snapshot-name
The host-name is the machine's domain name ,you can ssh this machine and click shell command **hostname**
to see the domain name.The snapshot-name is the machine's snapshot name if you have created the snapshot.
- If you are in normal shell environment, use virsh snapshot-delete host-name snapshot-name
- If you are in virsh shell environment,use snapshot-delete host-name snapshot-name
- Revert a snapshot to a machine
virsh snapshot-revert host-name snapshot-name & snapshot-revert host-name snapshot-name
- Undefin a virt machine
virsh undefine host-name & undefin host-name
