[ptls][tc] 2026 OpenStack Marketing & Messaging Priorities
by Allison Price 12 Jan '26

12 Jan '26

Hi everyone, I wanted to share the big focuses for OpenInfra Foundation marketing around OpenStack messaging as I think this could be helpful as we think about overall milestones for OpenStack as well as positioning for Gazpacho and Hibiscus. I would love your help in identifying upstream and community work throughout the year that can help amplify these messaging priorities. OpenStack as the OSS Infrastructure Standard to Support AI Workloads This is a massive, quickly growing space, and it’s critical to keep OpenStack relevant as these systems get built out. It will be our primary focus for 2026. Specifically here, I want to learn more about efforts around hardware diversification efforts as this is a common concern I have heard when scaling to support AI workloads as more new hardware is introduced. Digital Sovereignty: Building a Global Network of Localized Clouds In Europe we have seen digital sovereignty provide a unique opportunity for OpenStack and we are seeing this extend to new geographies rapidly. This isn’t limited to code, but also to the OpenStack community culture in areas like open governance. Kendall Nelson will be following up on a larger effort around this soon. VMware Migration While VMware Migration will not be the primary focus this year, it continues to provide significant momentum for OpenStack adoption. As new features are built or strengthened to support this transition, we need to be prepared to share that more broadly. This is not an exhaustive list of messaging around OpenStack, but are priorities that the OpenInfra Foundation has identified to maximize OpenStack exposure in the broader open source and cloud market. If it would be helpful, I am happy to join an OpenStack TC meeting or schedule an ad hoc meeting to discuss these priorities and any feedback or concerns you may have as well as opportunities to maximize impact. Thanks, Allison Allison Price VP of Marketing & Community, OpenInfra Linux Foundation p: +1-214-686-6821 e: allison(a)openinfra.dev e: aprice(a)linuxfoundation.org

[cinder] volume migration and multipathing
by Karl-Heinz Preuß 12 Jan '26

12 Jan '26

Hi Everyone, I'm trying to migrate cinder volumes from one backend to another. Namely I'm migrating from an HPE Nimble Storage backend to a Ceph backend. My Problem: the volume migration speed is kinda sluggish - around 100 MB/s. I can read from a Nimble backed volume way faster. And of course the Ceph can also write more than 1GB/s. After quite some debugging, the problem seems to be: cinder uses multipathing to access the Nimble backed volumes. But for some reason cinder's volume migration explicitly doesn't use multipathing. (I found "multipath=false" in the cinder logs when looking for my slow migrations.) Question: is there a way to configure cinder to use multipathing for volume migrations when available. -- Karl-Heinz Preuß Linux Consultant Tel.: +49 1515 5806243 E-Mail: preuss(a)b1-systems.de B1 Systems GmbH Osterfeldstraße 7 / 85088 Vohburg / https://www.b1-systems.de GF: Ralph Dehner / Unternehmenssitz: Vohburg / AG: Ingolstadt, HRB 3537

[aco][ansible] PRs for the ansible collection
by James Hewitt-Thomas 12 Jan '26

12 Jan '26

Hi all, I've made a few proposed changes for the ansible collection, not sure on the process so thought I'd reach out and check. I've got them passing the zuul checks - is there anything I need to do to request reviewers, or is it just an it'll happen over time thing? There's no urgency, just making sure I'm not leaving things in limbo. Thanks, James.

[ceilometer] ceilometer metrics for list fields in event payloads
by NITIN GUPTA 12 Jan '26

12 Jan '26

Hello Ceilometer Team! Good Day! Could you please suggest, how to create ceilometer metrics for list fields in event payloads when creating Gnocchi resources? Looks like Ceilometer doesn't iterate over list fields in event payloads when creating Gnocchi resources. Is this a known issue? From the below Sample payload, I'm looking to create a separate metric for "vcpus" field (for example) from each item in "reservations", which is a list of dictionary type of data in the payload. 'payload': { 'lease_id': 'f94182be-70e2-4f3f-bc8d-a1d1c2eea0aa', 'user_id': '2cf63f4ecf7740f5ac9ef4adfa4cdf5e', 'project_id': '07f1a09ab11543bb9080d260a98d812c', 'trust_id': '0037eb9121f04cdc94c39628a8354dde', 'start_date': '2025-12-15T16:18:00.000000', 'end_date': '2025-12-15T16:22:00.000000', 'status': 'PENDING', '*reservations*': [ { 'id': '1fffeb17-599d-441a-80e0-ca6d9044fd36', 'lease_id': 'f94182be-70e2-4f3f-bc8d-a1d1c2eea0aa', 'resource_id': 'c9daade3-4a85-4122-bec2-f34b7a849a01', 'resource_type': 'virtual:instance', 'status': 'pending', 'missing_resources': False, 'resources_changed': False, 'created_at': '2025-12-15 16:18:07', 'updated_at': '2025-12-15 16:18:10', '*vcpus*': 1, 'memory_mb': 1024, 'disk_gb': 20, 'amount': 1, 'affinity': None, 'resource_properties': '', 'flavor_id': '1fffeb17-599d-441a-80e0-ca6d9044fd36', 'aggregate_id': 292, 'server_group_id': None }, { 'id': '97df8162-d756-44c0-a27f-c832101577e8', 'lease_id': 'f94182be-70e2-4f3f-bc8d-a1d1c2eea0aa', 'resource_id': '4a3e20b1-5f63-46b1-a61b-13a267fd829a', 'resource_type': 'virtual:instance', 'status': 'pending', 'missing_resources': False, 'resources_changed': False, 'created_at': '2025-12-15 16:18:05', 'updated_at': '2025-12-15 16:18:07', '*vcpus*': 1, 'memory_mb': 1024, 'disk_gb': 20, 'amount': 1, 'affinity': None, 'resource_properties': '', 'flavor_id': '97df8162-d756-44c0-a27f-c832101577e8', 'aggregate_id': 291, 'server_group_id': None } ], 'events': [{'id': '4cea5a4f-53f4-4a69-969b-74a5869c7ab1', 'lease_id': 'f94182be-70e2-4f3f-bc8d-a1d1c2eea0aa', 'event_type': 'end_lease', 'time': '2025-12-15T16:22:00.000000', 'status': 'UNDONE', 'created_at': '2025-12-15 16:18:10', 'updated_at': None}, {'id': '63b51fc9-5eca-4729-8f5e-a3659e7db24b', 'lease_id': 'f94182be-70e2-4f3f-bc8d-a1d1c2eea0aa', 'event_type': 'start_lease', 'time': '2025-12-15T16:18:00.000000', 'status': 'UNDONE', 'created_at': '2025-12-15 16:18:10', 'updated_at': None}, {'id': 'bba382f6-47d8-4bb0-b3aa-0a65c6959ed9', 'lease_id': 'f94182be-70e2-4f3f-bc8d-a1d1c2eea0aa', 'event_type': 'before_end_lease', 'time': '2025-12-15T16:18:00.000000', 'status': 'UNDONE', 'created_at': '2025-12-15 16:18:10', 'updated_at': None}], 'name': 'lease-short-ins', 'created_at': '2025-12-15 16:18:05', 'updated_at': '2025-12-15 16:18:10', 'degraded': False } Best regards. -- NITIN GUPTA

[release] Release countdown for week R-11, Jan 12 - 16
by Elõd Illés 09 Jan '26

09 Jan '26

Development Focus ----------------- We are now past the Gazpacho-2 milestone, and entering the last development phase of the cycle. Please review the late milestone-2 release patches at https://review.opendev.org/q/topic:gazpacho-milestone-2 if you have not done so already! Teams should otherwise be focused on implementing planned work for the cycle. Now is a good time to review those plans and reprioritize anything if needed based on the what progress has been made and what looks realistic to complete in the next few weeks. General Information ------------------- Looking ahead to the end of the release cycle, please be aware of the feature freeze dates. Those vary depending on deliverable type: * General libraries (except client libraries) need to have their last feature release before Non-client library freeze (February 19th, 2026). Their stable branches are cut early. * Client libraries (think python-*client libraries) need to have their last feature release before Client library freeze (February 26th, 2026) * Deliverables following a cycle-with-rc model (that would be most services) observe a Feature freeze on that same date, February 26th, 2026. Any feature addition beyond that date should be discussed on the mailing-list and get PTL approval. After feature freeze, cycle-with-rc deliverables need to produce a first release candidate (and a stable branch) before RC1 deadline (March 12th, 2026) * Deliverables following cycle-with-intermediary model can release as necessary, but in all cases before Final RC deadline (March 26th, 2026) Upcoming Deadlines & Dates -------------------------- Non-client library freeze: February 19th, 2026 (R-6 week) Client library freeze: February 26th, 2026 (R-5 week) Gazpacho-3 milestone: February 26th, 2026 (R-5 week) Előd Illés irc: elodilles @ #openstack-release

[Nova] Proposal: NetApp FlexGroup Backend for Ceph-like Ephemeral Storage Performance on NFS
by Borra, Jayaanand 09 Jan '26

09 Jan '26

Hi everyone, Happy New Year to all! I hope you all had a great holiday season. I'm reaching out to share a proposal we've been working on that addresses a performance challenge many enterprises face with ephemeral storage in Nova. Context: Currently, OpenStack deployments running on NFS-based storage (like NetApp FlexGroups) face a significant performance penalty compared to Ceph RBD due to the QCOW2-over-NFS approach. The hypervisor manages Copy-on-Write operations, which introduces: * Double filesystem metadata overhead (QCOW2 on top of NFS) * CPU tax on compute nodes for CoW management * Slower instance provisioning compared to Ceph's instant cloning We are planning to implement solution that leverages NetApp's FlexClone technology through the ONTAP REST API to achieve Ceph-like performance while maintaining the operational simplicity of NFS. Essentially, we're offloading the cloning operation to the storage array itself, making instance creation a metadata-only operation (sub-second) with zero data copying. The implementation involves creating a new NetAppNfs image backend class in nova/virt/libvirt/imagebackend.py that calls the ONTAP REST API's /storage/file/clone endpoint instead of traditional file copy operations. I'm wondering if anyone has insights into: * Similar efforts: Has anyone explored or implemented storage-side cloning for other NFS vendors? * Design concerns: Any architectural red flags with this approach in the Nova driver? * Security practices: Best approach for managing storage credentials and oslo.privsep<vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html> integration? * Community interest: Would this be valuable for other NFS deployments? This will enable high-performance ephemeral storage from, so I'm curious if others have encountered this limitation and whether there's are any known limitation with this approach. Thanks in advance for any guidance or suggestions! Best regards, Jayaanand.
