Use the Xen master command (xm) with the create option to create a domain on which you’ll run a new instance of your virtual operating system (aka guest OS). First, however, you’ll need to create a domain configuration file: simply clone and edit of the Xen canned config files in /etc/xen folder, e.g., xmexample1 or xmexample2.
xm create -c mydomainconfigfile
After you’ve created the domain, you can run xm list to check that it has been started properly (if there is an issue, you’ll see it on the terminal from which you started the xm create command)
