Hi Novas! Here is my summarized plans for Ussuri about continuing the work on supporting qos neutron ports (those that has bandwidth resource request) in nova. What is missing: * Tempest coverage is missing for migrate and resize support that is merged in Train. This work is already underway and bugs has been caught [1][2] * Support evacuate, live migrate, unshelve. The work is described in [3][4] and the first set of patches for the evacuation support is up for review [5] * Support for cross cell resize with qos port needs some work. Matt prepared the cross cell resize code already in a way that no new RPC change will be needed [6] and I have a plan what to do [7]. * InstancePCIRequest persists parent_ifname during migration but the such change is not rolled back if the migration fails. This is ugly but I think it does not cause any issues [8]. I will look into this to remove the ugliness. The bandwidth support for the nova-manage heal_allocation tool was merged in Train. Originally I planned to backport that to Stein but that patch grown so big and incorporated may refactors along the way that I'm not sure any more that it is reasonable to backport it. I'm now thinking about keeping it as-is and suggesting operators to install Train nova in a virtualenv to run heal allocations for bandwidth aware servers if needed in Stein. I do have to run some manual tests to see if it actually works. Any feedback is welcome! cheers, gibi [1] https://bugs.launchpad.net/nova/+bug/1849695 [2] https://bugs.launchpad.net/nova/+bug/1849657 [3] https://blueprints.launchpad.net/nova/+spec/support-move-ops-with-qos-ports-ussuri [4] https://specs.openstack.org/openstack/nova-specs/specs/ussuri/approved/support-move-ops-with-qos-ports-ussuri.html [5] https://review.opendev.org/#/q/status:open+project:openstack/nova+branch:master+topic:bp/support-move-ops-with-qos-ports-ussuri [6] https://review.opendev.org/#/c/635080/43/nova/compute/manager.py@5375 [7] https://review.opendev.org/#/c/633293/49/nova/compute/manager.py@4742 [8] https://review.opendev.org/#/c/688387/6/nova/compute/manager.py@3404
