Current aggregate APIs allow user to add multi AZs to a host, but Openstack support single AZ of a host. When booting an instance, nova uses the first AZ assigned to a host,even if user assigned multi AZs to the host and user chose the second AZ to boot an instance. So multi AZs aren't supported by current Openstack design, we should fix aggregate APIs to align the design . This patch is for limit user to add multi AZs using aggregate-add-host API. The part 2 limits user to add multi AZs using aggregate update and aggregate metadata update API, here is the link: I18ad1ac22c6aee298ccc75c978b85241ae1ac616 Fixes: bug #1196893 Change-Id: I788782a9f21ec2672551f75123753175bb268586

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
