Availability Zones and host aggregates

Folks I have a few questions around Availability zones and host aggregates in Grizzly.

  1. Are all availability zones always associated with host aggregates but not all host aggregates are associated with availability zones, correct? Or is this changing so that there is always 1:1 correspondence between availability zone and host aggregates?

  2. Is there a way for non-admin users to discover availability zone via API? Access to host aggregate APIs seems to be limited to admin users. Without discovering AZs, it would be hard for end users to place their VM in appropriate AZ.

Would appreciate help! TIA. -paul

Please read Availability Zones and Host Aggregates in OpenStack Compute (Nova). I think it covers your questions.

Thank you. I did go thru the blog post.. The statement "The concept of host aggregates is only exposed to cloud administrators" is an issue -- How will end users who are trying to launch a VM going to find out about AZs (or Host Aggregates, used synonymously) if they don't have admin creds?

We have the same issue. We are planning to solve it by creating separate image for each zone (although the images themselves are same). With that user would be able to pick where he wants to place the VM.
