| + | It seems that this operation can be performed even on a running VM. | ||
| + | |||
| + | Pick target VM uuid: | ||
| + | <code> | ||
| + | > xe vm-list is-control-domain=false is-a-snapshot=false | ||
| + | </code> | ||
| + | |||
| + | Create the snapshot: | ||
| + | <code> | ||
| + | > xe vm-snapshot uuid=<vm-uuid> new-name-label=<snapshotname> | ||
| + | <snapshot-uuid> | ||
| + | </code> | ||
| + | |||
| + | Transform the snapshot into a VM to be able to save it to a file: | ||
| + | <code> | ||
| + | > xe template-param-set is-a-template=false ha-always-run=false uuid=<snapshot-uuid> | ||
| + | > xe vm-export vm=<snapshot-uuid> filename=<filename>.xva | ||
| + | Export succeeded | ||
| + | </code> | ||
| + | The export operation can take a while... Be patient until you see the "Export succeeded" message. | ||
| + | |||
| + | Finally let's get rid of the snapshot: | ||
| + | <code> | ||
| + | > xe vm-uninstall uuid=<snapshot-uuid> force=true | ||
| + | </code> | ||
