#
# 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
#
#
# [private_interface] Interface used for vm networking connectivity. Required.
# [internal_address] Internal address used for management. Required.
# [public_interface] Public interface used to route public traffic. Optional.
#   Defaults to false.
# [fixed_range] Range of ipv4 network for vms.
# [network_manager] Nova network manager to use.
# [multi_host] Rather node should support multi-host networking mode for HA.
#   Optional. Defaults to false.
# [network_config] Hash that can be used to pass implementation specifc
#   network settings. Optioal. Defaults to {}
# [sql_connection] SQL connection information. Optional. Defaults to false
#   which indicates that exported resources will be used to determine connection
#   information.
# [nova_user_password] Nova service password.
#  [rabbit_host] RabbitMQ host. False indicates it should be collected.
#    Optional. Defaults to false,
#  [rabbit_password] RabbitMQ password. Optional. Defaults to  'rabbit_pw',
#  [rabbit_user] RabbitMQ user. Optional. Defaults to 'nova',
#  [glance_api_servers] List of glance api servers of the form HOST:PORT
#    delimited by ':'. False indicates that the resource should be collected.
#    Optional. Defaults to false,
#  [libvirt_type] Underlying libvirt supported hypervisor.
#    Optional. Defaults to 'kvm',
#  [vncproxy_host] Host that serves as vnc proxy. Optional.
#    Defaults to false. False indicates that a vnc proxy should not be configured.
#  [vnc_enabled] Rather vnc console should be enabled.
#    Optional. Defaults to 'true',
#  [verbose] Rather components should log verbosely.
#    Optional. Defaults to false.
#  [manage_volumes] Rather nova-volume should be enabled on this compute node.
#    Optional. Defaults to false.
#  [nova_volumes] Name of volume group in which nova-volume will create logical volumes.
#    Optional. Defaults to nova-volumes.
