How to specify host aggregate without modifying flavor?

I've created several host aggregates and want to boot an instance on one of them. I searched the web and was told to add metadata to aggregates and key to flavor. But this requires a flavor to be created for every aggregate. Can I specify the host aggregate for instances? Also, is it possible using heat?

The virtual machines are spinning up in aggregate based on meta data. When you choose a flavor, the meta data associated with this flavor will look for the aggregate which having same meta data. You cannot specify host aggregate for instances.

Thanks for your answer. I was looking for something like scheduler_hints. It's fine to know there isn't.

You can also set metadata keys for images, but you are at the same point of your question. You need to create an image for every availability zone
