  30 Setup fai or arch pxe (depending on $0 name)
  31 then start a virtual machine to test the config

  33 Note, sometimes shutting down the existing demohost vm
  34 fails. Just run again if that happens.
  35
  36 -r         Do not boot after install is complete
  37 -n         Create new qcow2(s) for vm. Good for testing partitioning
  38            script, to ensure a blank disk.
