--- prelude: > Add configuration options to enable the segments plugin to use the placement ReST API. This API enables the segments plugin to influence the placement of instances based on the availability of IPv4 addresses in routed networks. features: - A new section is added to neutron.conf, `[placement]`. - The `[placement]` section has two new options. - First option, `region_name`, indicates the placement region to use. This option is useful if keystone manages more than one region. - Second option, `endpoint_type`, indicates the type of the placement endpoint to use. This endpoint will be looked up in the keystone catalog and should be one of 'public', 'internal' or 'admin'.
