Hi Jay. We usually use [vmware] to tag discussion of VMware things. I almost didn't see this message.
In short, there is a plan and we're currently blocked because we have to address several other pressing issues in the driver before we can address this one. Part of this is due to the fact that we can't press harder on blueprints or changes to the VCDriver right now. I actually reported this bug and we've discussed this at https://wiki.openstack.org/wiki/Meetings/VMwareAPI the basic problem is that live-migration actually "works" but you can't presently formulate a command that activates the feature from the CLI under some configurations. That's because of the introduction of clusters in the VCDriver in Havana. To fix this, we have to come up with a way to target a host inside the cluster (as I pointed out in the bug) or we have to have some way for a live migration to occur between clusters and a way to validate that this can happen first. As for the priority of this bug, it's been set to Medium which puts it well behind many of the Critical or High tasks on our radar. As for fixing the bug, no new outward behaviors or API are going to be introduced and this was working at one point and now it's stopped. To call this a new feature seems a bit strange. So, moving forward... perhaps we need to re-evaluate the priority order on some of these things. I tabled Juno planning during the last VMwareAPI subteam meeting but I plan on starting the discussion next week. We have a priority order for blueprints that we set as a team and these are publicly recorded in our meeting logs and on the wiki. I'll try to do better advertising these things. You are of course invited... and yeah... if you're interested in what we're fixing next in the VCDriver that next IRC meeting is where we'll start the discussion.
