We talked about this during the newton midcycle and from what I remember
we wanted to make this depend on having the ability for users to know
what they are capable of doing with their server instance in any given
cloud. This has grown into the cross project capabilities API
discussions that happen with the API work group.
At this point, I don't think we have anyone working on doing anything
for a capabilities API in nova, nor do we have cross project agreement
on a perfect solution that will work for all projects. At the PTG in
Denver I think we just said we care less about having a perfect
guideline for all projects to have a consistent API, and more about
actually documenting the APIs that each project does have, which we do a
pretty good job of in Nova.
So I think live resize would be fine to pick up again if you're just
resizing CPU/RAM from the flavor and if we provide a policy rule to
disable it in clouds that don't want to expose that feature.
Cloudbase was originally driving it for Hyper-v so you might want to
talk with Claudiu Belu.
