# == Class: nova::compute::rbd
#
# Configure nova-compute to store virtual machines on RBD
#
# === Parameters
#
# [*libvirt_rbd_user*]
# (Required) The RADOS client name for accessing rbd volumes.
#
# [*libvirt_rbd_secret_uuid*]
# (optional) The libvirt uuid of the secret for the rbd_user.
# Required to use cephx.
# Default to undef.
#
# [*libvirt_rbd_secret_key*]
# (optional) The cephx key to use as key for the libvirt secret,
# it must be base64 encoded; when not provided this key will be
# requested to the ceph cluster, which assumes the node is
# provided of the client.admin keyring as well.
# Default to undef.
#
# [*libvirt_images_rbd_pool*]
# (optional) The RADOS pool in which rbd volumes are stored.
# Defaults to 'rbd'.
#
# [*libvirt_images_rbd_ceph_conf*]
# (optional) The path to the ceph configuration file to use.
# Defaults to '/etc/ceph/ceph.conf'.
#
# [*libvirt_images_rbd_glance_store_name*]
# (optional) Name of the Glance store that represents the local rbd cluster.
# If set, this will allow Nova to request that Glance copy an image from
# an existing non-local store into the one named by this option before
# booting so that proper Copy-on-Write behavior is maintained.
# Defaults to $facts['os_service_default'].
#
# [*libvirt_images_rbd_glance_copy_poll_interval*]
# (optional) The interval in seconds with which to poll Glance after asking
# for it to copy an image to the local rbd store.
# Defaults to $facts['os_service_default'].
#
# [*libvirt_images_rbd_glance_copy_timeout*]
# (optional) The overall maximum time we will wait for Glance to complete
# an image copy to our local rbd store.
# Defaults to $facts['os_service_default'].
#
# [*libvirt_rbd_connect_timeout*]
# (optional) The RADOS client timeout in seconds when initially connecting
# to the cluster.
# Defaults to $facts['os_service_default'].
#
# [*libvirt_rbd_destroy_volume_retry_interval*]
# (optional) Number of seconds to wait between each consecutive retry to
# destroy a RBD volume.
# Defaults to $facts['os_service_default'].
#
# [*libvirt_rbd_destroy_volume_retries*]
# (optional) Number of retries to destory a RBD volume.
# Defaults to $facts['os_service_default'].
#
# [*ephemeral_storage*]
# (optional) Whether or not to use the rbd driver for the nova
# ephemeral storage or for the cinder volumes only.
# Defaults to true.
#
# [*manage_ceph_client*]
# (optional) Whether to manage the ceph client package.
# Defaults to true.
#
# [*ceph_client_ensure*]
# (optional) Ensure value for ceph client package.
# Defaults to 'present'.
#
# [*package_ensure*]
# (optional) The state of qemu-block-extra package. This parameter has effect
# only in Ubuntu/Debian.
# Defaults to 'present'
#
# [*manage_libvirt_secret*]
# (optional) Manage the libvirt secret
# Defaults to true
#
# == Deprecated parameters
#
# [*rbd_keyring*]
# (optional) The keyring name to use when retrieving the RBD secret
# Default to undef
#
