The final design summit session at the Ocata summit was, as usual, the
review priorities session. The full etherpad is here:
https://etherpad.openstack.org/p/ocata-nova-summit-priorities
Given the short cycle and restricted core reviewer bandwidth we're
really only making resource providers and cells v2 review priorities for
the release, along with some other things those depend on.
Resource Providers
------------------
There are three efforts here which can be worked concurrently, but the
priority order is:
1. Making nova-scheduler use the placement service. Sylvain Bauza is
working on this.
2. Handling shared storage/IP pools. Chris Dent is working on the server
side aggregates changes for this and Jay Pipes is working on the client
side pieces in the resource tracker.
3. Custom resource classes. Jay Pipes is leading the development on this
and already has most, if not all, of the code up for review, some if it
already merged.
Cells v2
--------
1. Scheduler interaction. Dan Smith is leading the development work on
this, lots of code is up for review and some of the series is already
merged.
2. Adding the multi-cell simple python merge sort / filtering for
listing instances. Dan Smith signed up to work on this.
3. Quotas. Melanie Witt is owning this, and as pointed out in an earlier
recap on this specific session we might change how we do quotas for
cells v2 in the API.
4. CI testing. I'm signed up to work on this. Some of the work has
already gone into switching Ocata CI jobs (except cellsv1) to Neutron by
default, making nova-network fail to start unless you're in a cells v1
environment (dansmith wrote that patch), and then enabling cells v2 in
master branch jobs by default (there are grenade changes needed for
this). Eventually I'll be working on multinode (multicell) support here too.
----
There are two other peripheral efforts that are a review priority
because of cells v2 being dependent on them.
1. Restricting the server list filters/sort parameters. Kevin Zheng and
Alex Xu are working on this.
2. Moving neutron port creation to conductor. This is a dependency for
supporting routed networks which is a dependency for using neutron with
multiple cells. John Garbutt already started working on this in Newton
so this is just a continuation of that work in Ocata.
----
There are a few non-priority but still notable mentions of things we're
going to keep working on throughout the release:
1. Getting an agreement on the Cinder API rework effort which is needed
to eventually support volume multiattach. John Garbutt and myself are
working that from the Nova side, and John Griffith and Ildiko Vancsa
from the Cinder side.
2. Continuing to unwind the CI dependencies on nova-network. I'm working
on those efforts.
3. Get agreement on the discoverable capabilities API WG spec so we can
work on implementing that in Pike.
4. Get the gate-tempest-dsvm-security job created which tests with
Barbican as the key manager and it would verify signed images. This is a
foundation on which we need to later build in new security-related
features to Nova.
----
Finally, because of the short schedule, we agreed that there is just a
single feature freeze which is the same as the rest of OpenStack for the
Ocata release, which is January 26th. So there is no non-priority
feature freeze for Ocata.
