Hey,

Somebody may correct me, but to the best of my knowledge this functionality is currently not implemented in Nova.
I can assume there could be some custom scheduler filters/weighers in the wild (not 100% sure this can be done solely through scheduling though), but I personally haven't seen one so far.
Though I was asked a couple of times during last year about exactly the same thing. So you're totally not alone looking for a solution for spot instances.

Hello everyone,

I am working on a project in the OpenStack environment. More precisely, I am looking into the implementation of spot instances as a cost optimization strategy and better resource utilization.

If any community members could share their experiences and insights related to the following areas, it would be greatly appreciated.
Implementation Strategies: How did you go about implementing spot instances in your cluster?
Challenges Faced: Mention some of the challenges or limitations.
Best Practices: Do you have any recommendations or best practices that you would like to suggest for seamless deployment?

Thank you very much for your time and support.
