virt-install script for a standard guest

create-standard-guest.sh

#!/bin/bash

# This script assumes that there's an ISO installed somewhere (so that its contents can be browsed) and that that ISO is then exported as an NFS export.
# The kickstart file is pushed into the boot image so anaconda can draw from it.
# The serial part of extra-args enables virsh <guestname> console to work. It also allows for a console install.

# the location arg refers to a local loop mount of an iso that's THEN presented as an nfs export because the guest installer needs to find it from inside of its world
# the kickstart is hosted from some httpd somewhere so the installer can reach it
