+Setup fai or arch pxe (depending on $0 name)
+then start a virtual machine to test the config
+
+Note, sometimes shutting down the existing demohost vm
+fails. Just run again if that happens.

+-d When doing pxe, don't do dhcp setup. Good for when we
+ aren't on Ian's home network.
+-n Create new qcow2(s) for vm. Good for testing partitioning
+ script, to ensure a blank disk.
+-p Use pxe instead of autodiscover iso with fai.
+-c Use normal fai-cd iso is instead of autodiscover iso.
+-r Do not boot after install is complete
+-h|--help Print help and exit.
