Re: Instance IDs and Multiple Zones


Without fixing the integer ID problem, I'd vote for reserving some bits for zone ID.  I don't like the idea assigning ranges to zones.  But I think the right answer is to fix the integer ID problem.

However, this was discussed and settled before I was actively involved in the OpenStack code, so I didn't want to have this devolve into a resurrection of what had already been decided. If someone wants to restart that discussion, I'd certainly be interested, but that's not what I'm looking for in this thread.
