#
# This class is intended to serve as
# a way of deploying compute nodes.
#
# This currently makes the following assumptions:
#   - libvirt is used to manage the hypervisors
#   - flatdhcp networking is used
#   - glance is used as the backend for the image service
#
# TODO - I need to make the choise of networking configurable
