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 action works like pulling the plug on a physical server and then plugging it back in and turning it back on.

Only do a forced reboot as a last resort to forcibly retrieve the system from instances such as a critical error.

An HVM-mode VM without Citrix VM Tools installed can only be rebooted using a forced reboot. To avoid this situation, install Citrix VM Tools on all HVM virtual machines. For more information, see Citrix VM Tools.

To reboot a VM cleanly

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

The Reboot icon - a green circle with white lines radiating from its center.

Alternatively:

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

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

To do a forced reboot

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

The Force Reboot icon - a red icon with white lines radiating from the center.

Alternatively:

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