In https://review.openstack.org/#/c/18675/ changes were made to availability_zones in nova that change how they work:
Previously all services had an availability_zone, but the
availability_zone is only used for nova-compute. Services such as
nova-scheduler, nova-network, nova-conductor have always spanned all
availability_zones.
After this change only compute nodes (nova-compute), will have an
availability_zone. In order to preserve current APIs, when running:
* nova host-list (os-hosts)
* euca-describe-availability-zones verbose
* nova-manage service list
Internal services will appear in there own internal availability_zone
(CONF.internal_service_availability_zone)
Internal zone is hidden in euca-describe-availability_zones
(non-verbose)
CONF.node_availability_zone has been renamed to
CONF.default_availability_zone and is only used by the nova-api and
nova-scheduler. CONF.node_availability_zone still works but is
deprecated
23 availability_zone_opts = [
24 cfg.StrOpt('internal_service_availability_zone',
25 default='internal',
26 help='availability_zone to show internal services under'),
27 cfg.StrOpt('default_availability_zone',
28 # deprecated in Grizzly release
29 deprecated_name='node_availability_zone',
30 default='nova',
31 help='default compute node availability_zone'),
32 ]
updated API samples are also provided in the patch
