# TODO: Add support for choosing base image based on deployment_type and os
# wanted (os wanted needs support added in bin/cluster with sane defaults:
# fedora/centos for origin, rhel for online/enterprise)
# TODO: create a role to encapsulate some of this complexity, possibly also
# create a module to manage the storage tasks, network tasks, and possibly
# even handle the libvirt tasks to set metadata in the domain xml and be able
# to create/query data about vms without having to use xml the python libvirt
# bindings look like a good candidate for this
