Yet again, let me try to provide you a summary about our previous PTG, this time for the Zed release. You can see all the notes thanks to this read-only etherpad : https://etherpad.opendev.org/p/r.75a986ce3ac43bb74b93c5de63d84fe9 ### Cross-project discussions ### # Neutron cross-project discussion with Nova - The nova community asked how to require Neutron backends to support a list of Neutron API extensions (for example multiple port bindings). We discussed whether it was rather a documentation issue or a code issue, but eventually it was rather a supporting concern as we don't test all of the backends for Nova. We then agreed on discussing this during the next OpenInfra Summit in Berlin with operators then, if possible. - We agreed on providing a new job for verifying whether heal_instance_info_cache_interval is no longer needed. # Cinder cross-project discussion with Nova - We discussed how we could remove the os-brick rootwrap config from nova and rather moving the config into directly os-brick. We eventually agreed on trying to rather implement the rootwrap->privsep transition, hopefully, thanks to some Stephen's help ;) # Cyborg cross-project discussion with Nova - We agreed on continuing to accept to provide traits for Resource Providers for owners (OWNER_NOVA at least). Context is https://review.opendev.org/c/openstack/nova-specs/+/836583 and we discussed about some implementation nits. ### Nova specific topics ### # Procedural discussions - We discussed on Yoga retrospective. We were happy to not have a RC2, to have new contributors and to have provided features to Placement for the last two cycles. We agreed to stopping to accept blind rechecks and to use the review priority label. Eventually we agreed on maybe adding new stable cores. - We need to fix Placement tests that verify the number of traits as for the moment it creates some issues. We agreed on relaxing those tests and to add a PTL doc saying we would bump os-traits and os-resource-classes usage in placement before RC1. - We agreed on having the same deadlines that for the last cycle, which are, Spec approval freeze for Zed-2 milestone (July 14th), and FeatureFreeze for Zed-3 (Sep 1st). We will have two spec review days - We agreed on keeping the same release model for os-vif - We agreed on continuing to use the review priority label in Gerrit and encourage contributors to use it (once we land the necessary changes in Gerrit) - Follow-up discussion on the novaclient CLI deprecation we agreed on Yoga. We'll modify the spec template to ask for rather updating OSC instead of the shell, and how to return some warnings if you use the shell. - We agreed on having some bug triage rotation between our contributors. I'll explain it in our next team meeting today :-) - We agreed on saying 'Unsupported' instead of 'Deprecated" for some features that need help if we don't want to remove them :-) - Again, we loudly said ***NO FOR BLIND RECHECKS*** https://docs.openstack.org/project-team-guide/testing.html#how-to-handle-tes... # New Release cadence (ie. the tick-tock release balance) - We agreed on writing some guidelines in our Nova documentation explaining the differences between tick and tock releases from a nova perspective and what people could do. We agreed on *not* bumping the compute minimum supported version in a tick release. That would also be super cool if we could have some sphinx directive in reno that contributors would use if they add/modify things in a tock release but want operators to know in the next tick. # Planned API modifications - We agreed on testing new policy defaults in the gate and not yet enforce new scopes until we are sure everything works correctly. Devstack will need modifications for those enablements and proper communication has to be made to deployment projects to make sure they're on the same page before we change anything. - We agreed on deprecating the possibility to generate new keypairs thru the Nova API. Only keypair imports will be accepted in the future. - We agreed on some usecase for adding network domain name in our metadata API. Things have to be further discussed in a spec but the direction sounds reasonable. - We agreed on letting userdata be editables. Details were discussed about the limits of this new mutable field (configdrive et when to apply) but spec will be updated accordingly. - Being able to unshelve an instance by passing a destination seems a valid usecase, spec has to be reviewed besides the implementation. - We'll try to somehow ensure that renaming tenant_id into project_id in our API isn't yet again deferred to the next cycle, even tho the series is large and merge conflicts are important. - Manila shares could be attached or detached to instances thru a new API and notifications would be emitted # Other - Centos9 will be tested on a weekly basis in our gate at first - Nova healthcheck is definitely a thing we want, but we miss hands on deck. - having PCI devices being tracked in Placement is also something we'd love to see arriving on this cycle - we'll continue further testing emulated hardware. Maybe some blueprints would come up but we also said we'll try to give visibility on the periodic gate runs by looking at them in our weekly meeting. - We discussed a very interesting case with the Scaphandre project that needs to use virtio-fs for passing system usage to the guests. We eventually agreed on two possible directions, with one preferred, which is to reuse the Manila shares support we're going to add in Zed. - We can be smarter on placing guest CPUs on physical cores or dies, but this requires a blueprint at least as we agreed on providing some flavor extraspec or image property for letting operators to define the CPU placement. - Windows guests would benefit from new enlightenments in Zed if we merge some small change - Having CPU cores be externally managed by a daemon that would turn them on/off based on consumption seems a valid usecase. We discussed about some details but spec has to be reproposed. That's it. If you reached this line, kudos, you're brave. I tried to be short, but it looks to me I failed. Anyway, the source of truth remains the etherpad, just please avoid to amend it now. -Sylvain
