When prompted for a server enter ''localhost:5900''.A VNC window will subsequently appear containing the running guest system. == Shutting Down a Guest System == The ''shutdown'' option of the ''xm'' tool is used to shutdown a guest operating system. The operating system will perform an orderly shutdown when it receives the shutdown instruction: <pre>xm shutdown guestName</pre> where ''guestName'' is the name of the guest system, to be shutdown. == Pausing and Resuming a Guest System == A guest system can be paused and resumed using the ''xm'' tool's ''pause'' and ''restore'' options. For example, to pause a specific system named ''myXenGuest'': <pre>xm pause myXenGuest</pre> Similarly, to resume the paused system: <pre>xm resume myXenGuest</pre> Note that a paused system will not be restorable 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 ''save'' and ''restore'' the guest. == Saving and Restoring Xen Guest Systems ==
