When a new instance is created, the host value is set to None. As a corrolar, its AZ field is set to the default_availability_zone value. That's only when the host field is provided (ie. once the instance is started) that the AZ information is also updated. Unfornately, as the AZ module is using a cache system, it leaves the old AZ unchanged which can make the instance AZ data wrong. In order to fix that corner case, we need to compare both cache and instance values and if different, invalidate the cache key and leave it updated correctly by calling the AZ related information of the aggregate the host belongs to.

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:
Developers wishing to work on the OpenStack Nova project should always base their work on the latest Nova code, available from the master GIT repository at:
Developers should also join the discussion on the mailing list, at:
