+Setup fai or arch pxe (depending on $0 name)
+then start a virtual machine to test the config
+
+todo: make it so this can run this on a network we dont control, the 2
+ways I know which could work are either running in libvirt's the nated
+network, and altering the dnsmasq options for the dnsmasq that runs in
+that, or giving the vm a static ip and for resolving faiserver, and then
+for resolving "faiserver", either setup some static resolution in the
+vm, or give it the host machine's ip as a dns server, or in general
+change references of faiserver to faiserver.b8.nz (I like this idea
+because it helps in other cases too).
+
+Note, sometimes shutting down the existing demohost vm
+fails. Just run again if that happens.
+
+-d When doing pxe with -p, 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.

+Note: Uses GNU getopt options parsing style
