The Big Picture

A quieter week (18 threads, 27 messages) but a substantive one for anyone thinking past the current release. With the 2026.1 "Gazpacho" coordinated release ten weeks out (R-10) and milestone-2 behind us, project teams have shifted into reviewing implementation patches against approved specs. The most forward-looking thread, though, wasn't about Gazpacho at all: Intel TDX support is heading for Nova as part of a broader confidential-computing push. Meanwhile the Technical Committee continued chipping away at structural questions — what replaces uWSGI, how to keep the openstack.cloud Ansible collection maintained, the governance move of keystoneauth to the OpenStackSDK team, and the wind-down of Bitergia dashboards.

Development & Technical Decisions

Intel TDX comes to Nova. Anton Iacobaeus, who previously added Intel TDX support to Proxmox, announced he is targeting the same for Nova, with a blueprint posted and a spec drafted for the 2026.2 cycle. His read of the codebase: AMD SEV and SEV-ES are already implemented, SEV-SNP is in progress, and TDX shares enough with SEV-SNP that the two efforts can advance in tandem. He is explicitly asking for early feedback and concerns — a good moment for anyone invested in confidential VMs to weigh in before the design hardens. The Nova 2026.1 PTG etherpad holds the discussion thread.

The post-uWSGI question stays unresolved. Dmitriy Rabotyagov pushed back on the gunicorn/uvicorn options, noting they require a real web server in front for TLS termination and routing, which adds complexity (especially for DevStack). His view: the project should recommend an abstract WSGI-compatible handler and leave the implementation choice to deployers. He also corrected a common framing — uWSGI is not unmaintained (last release three months prior); its real gaps are the lack of HTTP/2 and ASGI, neither of which gunicorn solves. He floated the Rust-based Granian as a candidate that ticks the boxes on paper but lacks production validation. This is an ongoing TC discussion aimed at clarifying the line between CI convenience and production guidance, not a decision.

Neutron's IPv6 DVR for OVN is at a crossroads. Maximilian Stinsky-Damke surfaced the long-stalled IPv6 DVR feature for OVN (bug 1998609, patch 867513), which Roberto Bartzen Acosta carried across multiple cycles without core review and which is now blocked by merge conflicts. The spec was approved and merged, signaling community interest, but the patch hasn't gotten traction. Before investing in another rebase, Max is asking core maintainers point-blank whether there are architectural concerns, whether it's purely a reviewer-bandwidth issue, and whether a refreshed patch would actually get reviewed.

A PCRE2 migration and a Debian Trixie gate snag. Takashi Kajinami reported progress on migrating the whereto library (now 0.5.0) off PCRE3 to PCRE2, with patches up for cinder and glance needing review; doc jobs still pass only because of available wheels, so merging soon avoids future breakage. Separately, Nimesh Desai hit openstack-tox-py313 failures on debian-trixie nodes where libpcre3-dev is no longer available — the same obsolete-package theme from the other direction.

Heads Up / Action Needed

  • Kolla is dropping InfluxDB (Michał Nasiadka): the only supported version is v1, now EOL, with no interest in v2. Patches are tracked under topic kolla_drop_influxdb. Deployers relying on Kolla's InfluxDB should plan a migration.
  • Kolla OVN deploy breakage: Michal Arbet reported OVN failing to install in Kolla due to a handler-notification bug introduced by review 940428; he had a fix in hand. Worth pinning if you're deploying current Kolla-Ansible.
  • Feature freeze ahead. The TC's R-10 summary noted the next project-wide deadline is feature freeze on February 26, 2026; consult the Gazpacho schedule for project-specific deadlines.
  • April 2026 PTG: Kendall Nelson confirmed the dates — April 20–24, 2026 — with registration open and free. Team sign-up surveys to follow.
  • keystoneauth governance moved from the Keystone team to the OpenStackSDK team, where the TC expects better reviewer attention.

Community & Events

The Ops Radio Hour met January 23 and recapped a wide-ranging session: 2026 plans (the series continues), the upcoming survey, Cinder ops complexities, and a recurring pain point — running services like Neutron and Cinder in HA is hard, and the docs are tough for operators new to the platform to navigate. The next session was set for February 27 with HA architectures (guest Tyler Stachecki), backups, and automation on the agenda. The recording is on YouTube.

The Digital Sovereignty Working Group held its kickoff meeting with strong international representation; the recording and etherpad are posted, with a poll out for the next meeting time.

The TC's R-10 summary also flagged a resource gap in the Ansible SIG: the openstack.cloud collection is a dependency for OpenStack-Ansible and Kolla but lacks review bandwidth — volunteers wanted. The TC also discussed the immediate sunsetting of Bitergia dashboards and the LFX Insights transition. On the operations side, Nguyễn Hữu Khôi shared a homegrown OpenStack CPU/RAM workload-balancing script, and a Neutron VPNaaS thread sought help routing multiple subnets across a two-site tunnel.
