[release] Release countdown for week R+0
by Thierry Carrez 28 Mar '25

28 Mar '25

Development Focus ----------------- We will be releasing the coordinated OpenStack 2025.1 Epoxy release next week, on April 2nd, 2025. Thanks to everyone involved in the 2025.1 Epoxy cycle! We are now in pre-release freeze, so no new deliverable will be created until final release, unless a release-critical regression is spotted. Otherwise, teams attending the virtual PTG should start to plan what they will be discussing there, by creating and filling team etherpads. You can access the list of PTG etherpads at: https://ptg.opendev.org/etherpads.html General Information ------------------- On release day, the release team will produce final versions of deliverables following the cycle-with-rc release model, by re-tagging the commit used for the last RC. A patch doing just that will be proposed soon. PTLs and release liaisons should watch for that final release patch from the release team. While not required, we would appreciate having an ack from each team before we approve it on Wednesday, so that their approval is included in the metadata that goes onto the signed tag. Upcoming Deadlines & Dates -------------------------- Final 2025.1 Epoxy release: April 2nd, 2025 Project Teams Gathering (virtual): April 7th-11th, 2025 -- Thierry Carrez (ttx)

[all][qa] QA tools (devstack/grenade/tempest) setup for new stable/2025.1 and current master
by Ghanshyam Mann 28 Mar '25

28 Mar '25

Hi All, The QA tools setup[1] for the new stable/2015.1 and the current master is completed. I would like to highlight a couple of things: * Recheck if devstack/gernade jobs on master or any backport were not running/testing correctly. * By default, grenade-skip-level-always is added in integrated gate templates as voting. As the current master is non-SLURP, Testing N-2 -> N upgrade is not mandatory, so the project can opt to make it non-voting or remove it from their integrated template[2].

[openstack-helm] health-probes timeout for neutron agents (l3 and dhcp) and nova compute
by Alberto Molina Coballes 27 Mar '25

27 Mar '25

Hi, We’re facing an issue when deploying OpenStack 2024.1 with OpenStack Helm and OVS, the health probes fail for neutron-l3-agent, neutron-dhcp-agent and nova-compute while the internal RPC communication between the nova and neutron components look fine: Neutron: openstack network agent list +--------------------------------------+--------------------+--------------------------------+-------------------+-------+-------+---------------------------+ | ID | Agent Type | Host | Availability Zone | Alive | State | Binary | +--------------------------------------+--------------------+--------------------------------+-------------------+-------+-------+---------------------------+ | 433c2b07-5c82-4545-991d-6d0de6044ae9 | DHCP agent | fig-virt-intdev-alberto-node-0 | nova | :-) | UP | neutron-dhcp-agent | | 56c050fa-e58e-46a6-8191-0d0d481de246 | Open vSwitch agent | fig-virt-intdev-alberto-node-0 | None | :-) | UP | neutron-openvswitch-agent | | 5ea28388-3fac-4ebb-bce4-6b210f8a3766 | Metadata agent | fig-virt-intdev-alberto-node-0 | None | :-) | UP | neutron-metadata-agent | | 6a4506ca-6fe4-489a-b370-6e426db40d50 | DHCP agent | fig-virt-intdev-alberto-node-1 | nova | :-) | UP | neutron-dhcp-agent | | 772a1d3a-b432-4ac3-8dfe-d3affc6f226d | Metadata agent | fig-virt-intdev-alberto-node-1 | None | :-) | UP | neutron-metadata-agent | | 7bd8360c-468a-4473-a470-abfb1ab435da | Open vSwitch agent | fig-virt-intdev-alberto-node-1 | None | :-) | UP | neutron-openvswitch-agent | | 9d362a63-5740-44ed-ac77-4548eee59205 | L3 agent | fig-virt-intdev-alberto-node-0 | nova | :-) | UP | neutron-l3-agent | | a2cc9dc4-1600-4c5d-a250-2e43cf062cf3 | L3 agent | fig-virt-intdev-alberto-node-1 | nova | :-) | UP | neutron-l3-agent | +--------------------------------------+--------------------+--------------------------------+-------------------+-------+-------+---------------------------+ The neutron-l3 and neutron-dhcp pods are not ready: k -n openstack get pods -l application=neutron |grep 'l3\|dhcp' neutron-dhcp-agent-default-fw5rm 0/1 Running 0 127m neutron-dhcp-agent-default-vh7c4 0/1 Running 0 127m neutron-l3-agent-default-4h5tp 0/1 Running 0 24m neutron-l3-agent-default-bdngv 0/1 Running 0 24m Because the health probes fail: Events: Type Reason Age From Message ---- ------ ---- ---- ------- Warning Unhealthy 4m38s (x119 over 127m) kubelet Readiness probe failed: Health probe timed out.

Some VMs have been launched in this environment successfully (nova-compute), getting IP from the DHCP agent or adding floating IPs (l3-agent) and the OpenStack behaviour is normal. So I’m confused about the health-probes failing. Any idea on what can be wrong or what to check is welcome. Thanks! Alberto Note: This is a Kubernetes cluster running on two VMs (OpenStack). This virtual environment has been redeployed several times with some modifications and the issue is fully reproducible: the probes for nova-compute, neutron-l3-agent and neutron-dhcp-agent always fail.

[designate] multiple zone catalogs with multiple zones
by Benedikt Trefzer 27 Mar '25

27 Mar '25

Hi List I'm trying to create an additional pool with a separate catalog zone. For the default pool, I can do an AXFR to the catalog domain, this works (either without tsig key or with a tsig). For the catalog of the second pool cannot be queried (Log sais Zone not found). In the DB I can see the zone. Questions: - Is it possible to have multiple pools with separate catalogs, does anyone have a running setup ? - Reading this [1] line in the code, I assume It's not possible having multiple zones without using tsig, correct ? Thanks a lot. Benedikt [1] https://opendev.org/openstack/designate/src/branch/master/designate/mdns/ha…
