Greetings, Last week we had an in-person Nova meetup. Bluehost was a wonderful and generous host. Many thanks to them. :-)
Here's some observations and a summary of some of the things that we discussed: 1) Mark McClain (Neutron PTL) and and Mark Washenberger (Glance PTL) both attended. Having some cross-project discussion time was *incredibly* useful, so I'm thankful they attended. This makes me very optimistic about our plans to have a cross-project day at the Atlanta design summit. We need to try to get as many opportunities as possible for this sort of collaboration. 2) Gantt - We discussed the progress of the Gantt effort. After discussing the problems encountered so far and the other scheduler work going on, the consensus was that we really need to focus on decoupling the scheduler from the rest of Nova while it's still in the Nova tree. Don was still interested in working on the existing gantt tree to learn what he can about the coupling of the scheduler to the rest of Nova. Nobody had a problem with that, but it doesn't sound like we'll be ready to regenerate the gantt tree to be the "real" gantt tree soon. We probably need another cycle of development before it will be ready. As a follow-up to this, I wonder if we should rename the current gantt repository from openstack/gantt to stackforge/gantt to avoid any possible confusion. We should make it clear that we don't expect the current repo to be used yet. 3) v3 API - We discussed the current status of this effort, including the tasks API, and all other v3 work. There are some notes here: https://etherpad.openstack.org/p/NovaV3APIDoneCriteria I actually think we need to talk about this some more before we mark v3 as stable. I'll get notes together and start another thread soon. 4) We talked about Nova's integration with Neutron and made some good progress. We came up with a blueprint (ideally for Icehouse) to improve Nova-Neutron interaction. There are two cases we need to improve that have been particularly painful. The first is the network info cache. Neutron can issue an API callback to Nova to let us know that we need to refresh the cache. The second is knowing that VIF setup is complete. Right now we have cases where we issue a request to Neutron and it is processed asynchronously. We have no way to know when it has finished. For example, we really need to know that VIF plumbing is set up before we boot an instance and it tries its DHCP request. We can do this with nova-network, but with Neutron it's just a giant race. I'm actually surprised we've made it this long without fixing this. 5) Driver CI - We talked about the ongoing effort to set up CI for all of the compute drivers. The discussion was mostly a status review. At this point, the Xenserver and Docker drivers are both at risk of being removed from Nova for the Icehouse release if CI is not up and running in time. 6) Upgrades - we discussed the state of upgrading Nova. It was mostly a review of the excellent progress being made this cycle. Dan Smith has been doing a lot of work to get us closer to where we can upgrade the control services at once with downtime, but roll through upgrading the computes later after service is back up. Joe Gordon has been working on automating the testing of this to make sure we don't break it, so that should be running soon. Lastly, everyone in attendance seemed to really enjoy it, and the overwhelming vote in the room was for doing the same thing again during the Juno cycle. Dates and location TBD.
