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 ?

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.

Subject: [openstack-dev] [Nova] Add scheduler-hints when
migration/rebuild/evacuate
Hi,
Currently migration/rebuild/evacuate didn't support pass
scheduler-hints, that means any migration
can't use schedule-hints that passed when creating instance.
Can we add scheduler-hints support when migration/rebuild/evacuate?
That
also can enable user
move in/out instance to/from an server group.
Thanks
Alex
