Reboot a VM

Mar 13, 2013

There are two different ways of rebooting a VM in XenCenter:

  • A soft reboot performs an orderly shutdown and restart of the VM.
  • A forced reboot is a hard reboot which restarts the VM without first performing any shut-down procedure. This works in the same way as pulling the plug on a physical server and then plugging it back in and turning it back on.

A forced reboot should only be done as a last resort to forcibly retrieve the system from instances such as a critical error.

A VM running in HVM mode (that is, without XenServer Tools installed) can only be rebooted using a forced reboot; to avoid this, you should install XenServer Tools on all HVM virtual machines.

To reboot a VM cleanly

In the Resources pane, select the VM and then click Reboot on the toolbar.

Alternatively:

  • Right-click and click Reboot on the Resources pane shortcut menu.
  • On the VM menu, click Reboot.

The VM is shut down and rebooted. When this process is complete, its status indicator in the Resources pane changes back to .

To do a forced reboot

In the Resources pane, select the VM and then click Force Reboot on the toolbar.

Alternatively:

  • Right-click and click Force Reboot on the Resources pane shortcut menu.
  • On the VM menu, click Force Reboot.

The VM is immediately shut down and rebooted. When this process is complete, its status indicator in the Resources pane changes back to .
