  30 Setup fai or arch pxe (depending on $0 name)
  31 then start a virtual machine to test the config
  32
  33 Note, sometimes shutting down the existing demohost vm
  34 fails. Just run again if that happens.
  35
  36 -d         Don't do dhcp setup for when we aren't on Ian's home network.
  37 -n         Create new qcow2(s) for vm. Good for testing partitioning
  38            script, to ensure a blank disk.
  39 -p         Use pxe instead of autodiscover iso with fai.
  40 -r         Do not boot after install is complete
  41 -h|--help  Print help and exit.
