Reboot a VM

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 icon. A green circle with white lines radiating from its centre. 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 VM Start icon. A VM icon with a green play icon overlaid..

To do a forced reboot

In the Resources pane, select the VM and then click Force Reboot icon. A red icon with white lines radiating from the centre. 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 VM Start icon. A VM icon with a green play icon overlaid..
