Indeed, Smart Scheduler is something that could help NFV use-cases. My
only concern is about the necessary steps for providing such a feature,
with regards to the scheduler breakout that is coming.

Could you please make sure the current nova-spec [1] is taking in
account all other efforts about the scheduler, like scheduler forklift
[2], on-demand resource reporting [3] or others ? It also seems the spec
is not following the defined template, could you please fix it ? It
would be easier to review your proposal.

Gantt and Nova scheduler teams are attending a weekly meeting every
Tuesday at 3pm UTC. Would you have a chance to join, it would be great
to discuss about your proposal and how we can identify all the
milestones for this and potentially track progress on it.

Thanks,
-Sylvain
