<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hello,<br>
<br>
I am willing to restart working on it, if it actually has a chance of getting approved. Last time, the spec got 2 x +2's and ~12 +1's [1].<br>
<br>
I don't know how soon the capabilities thing can become a real thing, but IMO, we can go with Matt's suggestion of disabling the feature by default through policy.<br>
<br>
Restored and reproposed the spec for Queens btw.<br>

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

Thanks,<br>
