[Masakari][HA][Antelope] Host failure not detected in 3-node controller+compute cluster
by Thamanna Farhath 24 Dec '25

24 Dec '25

Hello OpenStack community, I am testing Masakari host failure recovery on OpenStack 2023.1 (Antelope) deployed using Kolla-Ansible. Environment: 3 nodes Each node runs controller + compute Pacemaker + Corosync deployed on all 3 nodes Masakari enabled (hostmonitor, instancemonitor, engine, api) pacemaker-remote not used (all nodes are full Pacemaker members) Masakari segment: service_type = COMPUTE recovery_method = auto Tests performed: Process-level failures (qemu, libvirt) → detected correctly nova-compute stop → detected (no evacuation, expected) Host failure test: Powered off one compute/controller node Also tested systemctl stop corosync Issue: Pacemaker shows the node as OFFLINE However: No Masakari HOST_DOWN notification is generated No evacuation is triggered masakari-hostmonitor logs do not show host failure handling Question: In a 3-node controller+compute Pacemaker cluster, is Masakari expected to detect host failure directly from Pacemaker membership events without pacemaker-remote? Are there any additional requirements needed for Masakari host failure detection in this topology? Any guidance or references would be greatly appreciated.

[ceilometer] ceilometer metrics for list fields in event payloads
by NITIN GUPTA 23 Dec '25

23 Dec '25

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

[nova][cinder][neutron] Heartbeat improvement: checking if main thread responds to rabbit ping
by Thomas Goirand 23 Dec '25

23 Dec '25

tl;dr: I want to implement main thread ping in the heartbeat tread via rabbitmq to make sure the main thread is alive when reporting a service status, I'd like to have opinions. Hi, I already wrote about this on #openstack-cinder, but nobody replied to me. Anyways, I think it's a topic that is cross-project, so I want to open it in this list. After a rabbitmq outage due to a disk full in our infra, we restarted our rabbitmq cluster. Everything seemed to come back normally, but we later discovered that the main threads of cinder-volume and cinder-backup were dead, while the heartbeat thread was not, and was reporting the services as up. It took us some time to realize it, as this cluster isn't public cloud, and we could live with the errors. Though we don't want to leave things the way they are, as we want reliable monitoring to avoid painful support tickets from customers. Within Cinder, there's already all the infrastructure in place to enhance the hearbeat thread, and make it do more checks. However, currently, the Manager class isn't even instantiated and used when creating the service. Here's my proposal, currently only for Cinder, but hopefully, I'll also implement it in Nova and Neutron. When creating the cinder-volume using cinder/service.py, it's going to also create a manager, and attach it to the service. The ManagerVolume class will implement the is_working() method of the class Manager. In it, it's going to ping the main thread with rabbitmq, sending a ping message, to which the main thread must respond with a pong. If the pong isn't received within a timeout, is_working() will reply False. I started implementing it here: https://review.opendev.org/c/openstack/cinder/+/970796 Note that it's currently still a WIP, and there's more to work on, like some unit tests that are currently failing. I'm not posting the link to the patch to get a merge yet, and it's unfinished, but the current patch is probably enough to get the idea of what I want to implement. So, for each service, the heartbeat will do a ping, which will of course make more messages in Rabbit. Though I believe this is still a reasonable thing to do. With 200 Cinder service, and a heartbeat every 30 seconds per service, that's going to be an additional less than 15 messages per seconds. Considering a reasonable RabbitMQ service can eat 100k message per seconds, it should be ok. Now, this is for Cinder. Once it's done there, I intend to investigate Neutron next, but I'm not sure if it has all the facilities that Cinder offers. Maybe it'd be worth unifying this in oslo.messaging? I'm open to suggestions, but I'm unsure (yet) of what it would look like within one of the oslo libs (I'd have to look on how / where to do it: suggestions are welcome, as it would speed-up my work on it). Please let know your opinion on this, if this is a good idea or not, and if the Cinder team (and potentially Neutron and Nova) will be willing to accept such a patch. Cheers, Thomas Goirand (zigo)

[Nova] unified limit and pci alias combination support
by Masahito Muroi 23 Dec '25

23 Dec '25

Hi Nova folks, We're trying to use unified limit with alias PCI device information with following configuration. With this configuration, unified limit calculates the resources:CUSTOM_NVIDIA_T4 correctly, but nova-scheduler makes allocation_candidate request with duplicated CUSTOM_NVIDIA_T4 resources. From my quick check of the code, the unified limit and pci device alias usecase is not supported by the master branch now. I'm thinking to fix the issue and comming up with two idea to solve the issue. I want to hear the nova team's opinion which is better to fit the nova's code. Or please give me any comment if there is another better way. - idea1: nova-scheduler drops duplicated resources request if needed. Adding a configuration to drop duplicated situation and etc. - idea2: introduces a new flavor extra spec prefix, e.g. "placement:<RC>", to indicate the resource class comes from placement. # nova.conf [pci] device_spec = {"vendor_id":"8086", "product_id":"8d2d", "resource_class":"CUSTOM_NVIDIA_T4"} alias = {"name":"t4_pcie_16gb", "vendor_id":"8086", "product_id":"8d2d", "resource_class":"CUSTOM_NVIDIA_T4", "device_type":"type-PCI"} report_in_placement = true pci_in_placement = true [quota] driver = nova.quota.UnifiedLimitsDriver unified_limits_resource_strategy = require unified_limits_resource_list = class:CUSTOM_NVIDIA_T4, class:VCPU, class:MEMORY_MB, class:DISK_GB # openstack flavor show GPU_FLAVOR | Fields. | Value | +-------------+-----------------------------------------| | properties | pci_passthrough:alias='t4_pcie_16gb:1', | | | resources:CUSTOM_NVIDIA_T4='1' | # allocation candidate request query /allocation_candidates limit=1000 resources=CUSTOM_NVIDIA_T4:1 DISK_GB:10 MEMORY_MB:1024 VCPU:1 resourcesbb775ad3-f50c-4d3b-bb28-8993e4a664ca-0=CUSTOM_NVIDIA_T4:1 best regards, Masahito

[Masakari] Proposal to restart bi-weekly IRC meetings (poll for the 1st session)
by Sei Sano 23 Dec '25

23 Dec '25

Dear Kajinami, Sam Su (苏正伟) I’d like to restart the regular Masakari IRC meeting, which has been paused for a while, and resume it on a bi-weekly basis. Also, through the Japan OpenStack user community network, I have already reached out to a few people who are interested in Masakari (they are welcome to join as observers at first). As a first step, I propose holding a kick-off meeting to align on how we run the meeting going forward (bi-weekly schedule, agenda/minutes process, chair rotation, etc.). Could you please let me know your availability for the first meeting from the options below? * Option 1: Friday, 2025-12-19 06:00-07:00 (UTC) / 15:00-16:00 (JST) * Option 2: Monday, 2025-12-22 06:00-07:00 (UTC) / 15:00-16:00 (JST) * Option 3: Tuesday, 2025-12-23 06:00-07:00 (UTC) / 15:00-16:00 (JST) Please reply by 2025-12-17 23:59 UTC. If I don’t hear back by then, I will go ahead and schedule the first meeting on (tentatively) 2025-12-22 06:00-07:00 (UTC) / 15:00-16:00 (JST), so we can start moving again (and we can adjust for the next meeting if needed). Proposed location: OpenStack IRC (#openstack-masakari) Draft agenda: * Agreement to restart the regular meeting (bi-weekly cadence, day/time) * Near-term priorities (review backlog, bugs, releases/events, blueprints, etc.) * Lightweight meeting operations (chair/agenda/minutes) If you have any constraints (e.g., specific time windows that never work), please share them as well. Thanks, -- Sei Sano NTT DOCOMO BUSINESS, Inc. E-mail: sei.sano(a)ntt.com

[nova] Ephemeral storage potential features
by Karol Klimaszewski 22 Dec '25

22 Dec '25

Hello, In my company (CloudFerro) we have developed two features related to nova ephemeral storage (with libvirt virt driver) - "SPDK-based ephemeral storage backend" and "Multiple ephemeral storage backend handling" (both described below). Would these features be appropriate to be added to upstream? If yes, then should I start with creating a blueprint and proposing a spec for each of them so it is more clear what we want to introduce? Of course not both at once, since there is some code that makes one work with the other. For us it would probably be best if we upstreamed "SPDK-based ephemeral storage backend" first and then upstreamed "Multiple ephemeral storage backend handling" Description of SPDK-based ephemeral storage backend: We add a new possible value for [libvirt]/images_type in nova.conf: spdk_lvol. If this value is set then local disks of instances are handled as logical volumes (lvols). of locally run SPDK instance (on the same compute as VM). See https://spdk.io/doc/logical_volumes.html#lvol for docs on this subject. These are essentially a part of local NVMe disk managed by SPDK. We create and manage those lvols by making calls from nova-compute to SPDK instance with RPC (https://spdk.io/doc/jsonrpc.html) using provided python library (https://github.com/spdk/spdk/blob/master/python/README.md) We attach those lvols to instances by exposing them as vhost-blk devices (see https://spdk.io/doc/vhost.html) and specifying them as disks with source_type='vhostuser'. This method of exposing NVMe local storage allows for much better I/O performance than exposing them from local filesystem. We currently have working: creating, deleting, cold-migrating, shelving, snapshots, unshelving VMs with this storage backend. We don't have live migration working yet but have it in plans. This feature includes changes only to nova. Description of Multiple ephemeral storage backend handling: We add a new configuration option [libvirt]/supported_image_types to nova.conf of nova-compute and change the meaning of [libvirt]/images_type to mean default image type. If libvirt:image_type extra_spec is specified in flavor then VM is scheduled on compute with appropriate image type in its [libvirt]/supported_image_types. We use potentially multiple DISK_GB resource providers and construct appropriate request groups to handle this scheduling. This spec is also used to fill driver_info.libvirt.image_type field of BDMs with destination_type=local of this VM. (driver_info is new JSON serialized field of BDM) Then in compute if BDM specifies this field we use its value instead of [libvirt]/images_type to decide on imagebackend to use for it. This method of handling multiple backends only works after being enabled by administrators by setting libvirt:image_type on all their flavors and running nova-manage commands that update existing VMs. Without enabling everything works as it was before. This feature includes changes to nova and some new traits in os-traits (One per possible value of [libvirt]/images_type + one extra) Best regards, Karol Klimaszewski

[nova] How to use $aggregates with JsonFilter
by Andy Speagle 19 Dec '25

19 Dec '25

Hey Team, I'm trying to use scheduler hints using the JsonFilter that involve host aggregates. Based on the documentation and my quick perusal of the scheduler's HostState class... it seems like $aggregates are populated there for usage, but I can't seem to find the right magick to make a json query work to schedule an instance on a host that belongs to a specific aggregate based on simply the name of the aggregate... or perhaps metadata contained within. I think my lack of understanding of the structure of the $aggregates list in the scheduler's HostState class is tripping me up. Does anyone have any insight into this?... Thanks. -- Andy Speagle

#eventlet-removal Thank you for 2025
by Herve Beraud 18 Dec '25

18 Dec '25

Two years ago, we collectively acknowledged that we were facing a demanding and somewhat paradoxical challenge: engaging a significant amount of time and resources to move away from a problematic technology, eventlet, without the promise of immediate functional gains. At that time, this effort could easily have been perceived as a necessary but uncomfortable burden — work that does not ship new features, does not directly address new user requests, and yet requires deep focus, coordination, and perseverance. We deliberately chose not to ignore the problem, not to postpone it, and not to settle for half-measures. Today, as we are reaching the end of 2025, we can clearly state that this choice was the right one. This year has been particularly intense, productive, and revealing of what a committed open source community can achieve when it aligns behind a long-term objective. The migration effort has reached a decisive milestone: more than 61% of the impacted OpenStack deliverables have now shown significant progress. Twenty deliverables are fully migrated, while forty others are actively undergoing migration. More than 424 Gerrit patches proposed this year alone directly contribute to this collective effort. Beyond the numbers, 2025 has delivered concrete, structural results. Several major projects — including Ironic, Heat, Barbican, Mistral, and others — are now fully migrated. Eventlet itself has evolved, gaining support for recent Python versions (3.12, 3.13, 3.14), ensuring compatibility with modern OpenStack runtimes during the transition phase. Oslo.service introduced a new threading backend, offering a fully threading-based execution model. Cotyledon is actively progressing toward supporting new spawning methods. Neutron is now just one step away from completing its migration, Nova can run specific services in threading mode, and teams such as Cinder, Designate, Watcher, Cyborg, and many others have shown sustained and visible momentum. What we are witnessing is more than a migration. It is a collective act of responsibility. Just like the Python 2 to Python 3 transition, this effort is about securing the future, reducing systemic risk, simplifying maintenance, and restoring long-term innovation capacity. It is about choosing durability over comfort, clarity over accumulation, and sustainability over short-term convenience. The foundations we are laying today are already making OpenStack more robust, more predictable, and better prepared for what comes next. As we close this year, I want to express my sincere respect and gratitude to everyone involved. Maintainers, contributors, reviewers, operators, companies — your engagement, patience, and persistence have made this progress possible. The level of coordination and trust demonstrated throughout 2025 is a strong signal, not only for our community, but for the entire industry that relies on OpenStack. On behalf of this community initiative, thank you for your commitment throughout this year. You have proven, once again, that necessary work — even when it does not immediately shine — is often the work that matters the most. I wish you all restful holidays and precious time with your loved ones. -- Hervé Beraud Principal Software Engineer at Red Hat irc: hberaud https://github.com/4383/

[ironic] Retirement of VirtualPDU
by Jay Faulkner 17 Dec '25

17 Dec '25

Hi all, As it's clear the SNMP code in Ironic will be removed next cycle, and CI has been removed as well, we also will be needing to retire VirtualPDU as well -- either this cycle or next. VirtualPDU was never shipped for production use and only mapped SNMP calls into libvirt power actions for devstack. With these jobs removed, it no longer serves a purpose. Please speak up now if you oppose this retirement. Thanks! -- Jay Faulkner Open Source Developer G-Research OSS

[designate] Question about NS record update restriction in multi-region PRIMARY/SECONDARY setup
by Sylvain 16 Dec '25

16 Dec '25

Hi everyone, I hope this email finds you well. I'm reaching out to the community because I'm encountering a limitation with Designate that I don't fully understand, and I'm hoping someone can shed some light on the reasoning behind it or suggest alternative approaches. My Setup I'm running a multi-region Designate deployment with: - 3 independent Designate instances (one per region) - Each instance has its own pool with a single nameserver: - Region 1: ns.region1.net. - Region 2: ns.region2.net. - Region 3: ns.region3.net. This default configuration works perfectly for most of our use cases where zones are region-specific. What I'm Trying to Achieve For certain domains, I need to set up a PRIMARY/SECONDARY configuration across all three regions: - Region 1: PRIMARY zone for example.com - Region 2: SECONDARY zone for example.com - Region 3: SECONDARY zone for example.com For this to work correctly, the PRIMARY zone needs to have NS records pointing to all three nameservers so that: 1. DNS clients can query any of the three nameservers 2. Zone transfers are properly configured between primary and secondaries The Problem When I try to update the NS recordset on the primary zone, I get the error: Updating a root zone NS record is not allowed Steps I'm following: # List recordsets to get the NS recordset ID openstack recordset list example.com. # Attempt to update the NS recordset openstack recordset set example.com. <ns-recordset-id> \ --record ns.region1.net. \ --record ns.region2.net. \ --record ns.region3.net. This happens even when authenticated as an admin user. Why the Default Workaround Doesn't Work I understand that one typical solution is to modify the pool configuration to include all three nameservers. However, this doesn't work in my case because: - I don't want to change the default pool settings since most zones should only use their local regional nameserver - Modifying the pool in Region 1 would affect *all zones* created there, not just the ones I want to replicate My Questions I'm trying to understand the design decisions here, and I'd really appreciate any insights: 1. What's the reasoning behind blocking NS record updates on root zones? I'm not seeing the security or technical concern that this protects against. 2. Is this restriction something that could potentially be made configurable via policy? For example, allowing zone owners to update their own NS records when they have legitimate multi-region or high-availability requirements. 3. Are there any alternative approaches I should be considering for this multi-region PRIMARY/SECONDARY setup that I might be missing? 4. Would the community be open to discussing a potential enhancement that makes this more flexible? I understand if there are concerns, but I'd love to understand them better. Use Case Context This is a fairly standard DNS architecture for high availability and geographic distribution. Many organizations need to run primary and secondary nameservers across different regions or datacenters, and being able to configure the NS records accordingly seems like it should be a supported use case. Thank you very much for taking the time to read this, and I appreciate any guidance or feedback the community can provide! Best regards, Sylvain.

Upcoming metrics dashboard changes
by Ildiko Vancsa 16 Dec '25

16 Dec '25

Hi OpenStack community, Since the OpenInfra Foundation joined the Linux Foundation, we have been looking into opportunities to take advantage of the frameworks and tool sets that the Linux Foundation has, and some of you and your organizations are already familiar with. While the dashboards are still being built I would like to let you know that, as part of that effort, we will switch to LFX Insights[1] as the metrics dashboard for OpenInfra projects, including OpenStack, starting on __January 15, 2026.__ A couple things to note: - The new OpenStack metrics dashboard[2] is already available, but it is __still under active construction.__ - The set of metrics that is displayed on the new dashboard will not be identical with the metrics on the dashboard provided by Bitergia. - LFX Insights does not display affiliation information for individuals who are listed on the dashboard as contributors, for privacy reasons. However, if you already have an LF account[3], you will be able to check and update your affiliation information. Or, you can create a new LF account[4]. - You can learn more about the dashboard in the LFX Insights documentation[5]. - If your organization is an OpenInfra Foundation / Linux Foundation member already, the LF Organization Dashboard[6] is also available for a more company-centric view. The OpenStack Bitergia metrics dashboard[7] remains available __until January 14, 2026.__ Please let me know if you have any questions. Best Regards, Ildikö [1] https://insights.linuxfoundation.org/ [2] https://insights.linuxfoundation.org/project/OpenStack/ [3] https://openprofile.dev/ [4] https://docs.linuxfoundation.org/lfx/sso/create-an-account [5] https://insights.linuxfoundation.org/docs/introduction/what-is-insights/ [6] https://lfx.linuxfoundation.org/tools/organization-dashboard/ [7] https://openstack.biterg.io/ ——— Ildikó Váncsa Director of Community OpenInfra Foundation
