Re: [openstack-dev] [nova] About live-resize spec
Hello, 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]. 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. Restored and reproposed the spec for Queens btw.
