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