Class: tripleo::profile::base::nova::compute_libvirt_shared

Libvirt profile for tripleo. It will deploy Libvirt service and configure it.

Parameters

nova_rbd_client_name

(optional) name of RBD client defaults to hiera(‘nova::compute::rbd::libvirt_rbd_user’)

nova_rbd_ceph_conf_path

(Optional) The path where the Ceph Cluster config files are stored on the host defaults to ‘/etc/ceph’

step

(Optional) The current step in deployment. See tripleo-heat-templates for more details. Defaults to hiera(‘step’)

Parameters:

  • nova_rbd_client_name (Any) (defaults to: hiera('nova::compute::rbd::libvirt_rbd_user','openstack'))
  • nova_rbd_ceph_conf_path (Any) (defaults to: '/etc/ceph')
  • step (Any) (defaults to: Integer(hiera('step')))
