24.5 Suspending and Resuming a Guest System
A guest system can be suspended and resumed using the virsh tool’s suspend and resume options. For example, to suspend a specific system:
# virsh suspend guestName
Similarly, to resume the paused system:
# virsh resume guestName
Note that a suspended session will be lost if the host system is rebooted. Also, be aware that a suspended 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 (even after a reboot), it is necessary to save and restore the guest.
