One question to clarify: the project will be marked as reservable by calling Keystone API (from Climate) to store that info in the project extra specs in Keystone DB.
Is this correct?

>>> I think it should be a Climate "policy" (be careful, the name is confusing) : if admin wants to grant any new project for reservations, he should place a call to Climate. That's up to Climate-Nova (ie. Nova extension) to query Climate in order to see if project has been granted or not.

Now I think that it'll be better, yes.
I see some workflow like:

1) Mark project as reservable in Climate
2) When some resource is created (like Nova instance) it should be checked (in the API extensions, for example) via Climate if project is reservable. If is, and there is no special reservation flags passed, it should be used default_reservation stuff for this instance

Sylvain, is that ira you're talking about?


tl;dr : Yes, let's define/create a new endpoint for the need.

That's exactly what I'm thinking, Climate should manage reservations on its own (including any new model) and projects using it for reserving resources should place a call to it in order to get some information.
