A candidate UUID would be generated and checked for "first 8" uniqueness (I had already added a db method to locate by the first 8 chars of a UUID across nested zones). When an acceptable UUID was generated, it would be passed to the selected host along with the create request. The instance would only have to be created once.

That may be true, but only for the EC2 API, not the OpenStack API,
right? The question remains from my original post: do we really care
enough about this?

Put another way: do we want to expend more resources on an API we don't control?
