Yes, we support to specify the host, but schedule-hints is different thing. if we need use hints that passed from creating instance, that means we need to persistent schedule hints I remember we used to have a spec for store it locally ... I also remember we have one spec for persistent before, but I don't know why it didn't continue. And I think maybe we needn't persistent schedule-hints, just add pass new schedule-hints when migration the instance. Nova just need provide the mechanism. Best Regards!

Re: [openstack-dev] [Nova] Add scheduler-hints when migration/rebuild/evacuate
Yes, I remember that spec might talk about local storage (in local db?) and it can be the root cause And I think we need persistent storage otherwise the scheduler hints can't survive in some conditions such as system reboot or upgrade ?
