--- upgrade: - | Nova now uses keystoneauth1 configuration to set up communication with the placement service. Use keystoneauth1 loading parameters for auth, Session, and Adapter setup in the ``[placement]`` conf section. Note that, by default, the 'internal' interface will be tried first, followed by the 'public' interface. Use the conf option ``[placement].valid_interfaces`` to override this behavior. deprecations: - | Configuration options in the ``[placement]`` section are deprecated as follows: * ``os_region_name`` is deprecated in favor of ``region_name`` * ``os_interface`` is deprecated in favor of ``valid_interfaces``
