→Pausing and Resuming a Guest System
Note that a paused session will be lost if the host system is rebooted. Also, be aware that a paused system continues to reside in memory. To save a session such that it no longer takes up memory and can be restored to its exact state after a reboot, it is necessary to either ''suspend'' and ''resume'' or ''save'' and ''restore'' the guest.
== Suspending and Resuming a Guest OS ==
A running guest operating system can be suspended and resumed using the xm utility. When suspended, the current status of the guest operating system is written to disk and removed from system memory. A suspended system may subsequently be restored at any time (including after a hosty system reboot):
To suspend a guest OS named ''myGuestOS'':
<pre>
xm suspend myGuestOS
</pre>
To restore a suspect guest OS:
<pre>
xm resume myGuestOS
</pre>
== Saving and Restoring Xen Guest Systems ==
