You can boot guest domains by using the xm application. You can also use virsh and the Virtual Machine Manager to boot the guests. A prerequisite for booting a guest domain is to install a guest host first. This example uses the xm create subcommand:

# xm create -c guestdomain1 

The guestdomain1 is the configuration file for the domain you are booting. The -c option connects to the actual console after booting.
