In previous chapters we have covered the steps necessary to install and configure Xen and Xen based guest operating systems. This chapter is dedicated to explaining the ''xm'' tool, and how it can be used to manage guest operating systems from the command-line. If you prefer to use the graphical ''virt-manager'' tool to administer your Xen configuration see [[Managing and Monitoring Fedora based Xen Guest Systems]].
== Listing Guest System Status ==
The status of the host and guest systems may be viewed at any time using the ''list'' option of the ''xm'' tool. For example:
<pre>
su -
xm list
</pre>
The above command will display output containing a line for the host system and a line for each guest similar to the following:
<pre>
Name ID Mem VCPUs State Time(s)
Domain-0 0 389 1 r----- 1414.9
XenFed 305 1 349.9
myFedoraXen 300 1 0.0
myXenGuest 6 300 1 -b---- 10.6
</pre>
== Starting a Xen Guest System ==
A system can be started using the ''xm'' tool with the ''start'' option followed by the name of the guest operating system to be launched. For example:
<pre>
su -
xm start XenFed
</pre>
== Connecting to a Running Xen Guest System ==
Once the guest operating system has started, a connection to the guest may be established using either the ''vncviewer'' tool or the ''virt-manager'' console. To use ''virt-manager'', select ''Applications->System Tools->Virtual Machine Manager'', select the desired system and click ''Open''.
To connect using vncviewer enter the following command in Terminal window:
<pre>
vncviewer
</pre>
When prompted for a server enter ''localhost:5900''.
