  34 # Usage: ${0##*/} [OPTIONS]
  35 Setup fai or arch pxe (depending on $0 name)
  36 then start a virtual machine to test the config
  37
  38 Note, sometimes shutting down the existing demohost vm
  39 fails. Just run again if that happens.
  40
  41 -d         When doing pxe, don't do dhcp setup. Good for when we
  42            aren't on Ian's home network.
  43 -n         Create new qcow2(s) for vm. Good for testing partitioning
  44            script, to ensure a blank disk.
  45 -p         Use pxe instead of autodiscover iso with fai.
  46 -c         Use normal fai-cd iso is instead of autodiscover iso.
  47 -r         Do not boot after install is complete
  48 -h|--help  Print help and exit.
