[tc][all][security] Supporting Post-Quantum Cryptography in OpenStack code (all projects)
by Jean-Philippe Jung 26 Oct '25

26 Oct '25

Hi, I am the OpenStack Security Product Manager at Red Hat. I also support Post Quantum Cryptography in OpenStack and k8s (well, OpenShift for us), and I cover some areas of confidential computing. I see one existential risk to OpenStack in the near future: support for post-quantum cryptography (PQC) [0] Based on my latest discussion with industry experts, I expect that around 2029 (likely) or 2030 (at best), there would be powerful enough Q-Computers to break traditional cryptography. Meaning we have to prepare OpenStack to support post-quantum crypto (ML-KEM urgently, ML-DSA as soon as possible) in the upstream code. As we also need to provide time for operators/customers to implement the "fixed" code, we are in early 2028 territory to achieve sufficient PQC coverage in OpenStack upstream. This would give OpenStack users time to implement this code. Time is running out; we’re already almost in 2026! A point to keep in mind is that the initial PQC algorithms might fall short and be replaced in the future. Thus, this PQC support exercise should also be a “cryptographic agility” exercise: we should have a few libraries we know how to call, and if a new crypto algorithm comes out, it should be easy to enable it in the code. I used AI engines to have a look at the OpenStack upstream code (not all projects, but a chunk of the most commonly used), and I came back with 17 different cryptographic modules, 7 of which received no commits in over 2 years. It might be directly in the code or in pulled dependencies. The first step to solving a problem is recognizing we have one. We have a problem. I am seeking help from the TC to raise the urgency of this work across all OpenStack projects and to help me lead an effort to reduce the number of cryptographic modules used in OpenStack (my personal opinion is that there should be no more than five). Doing this may involve work in each OpenStack Project team; and I can help organize this effort. I'm seeking the following from the TC and/or project teams: Portions of this work will be isolated to specific repositories managed by a project team, while others will involve "cross-project" synchronization. What vehicles can we use to have a "call-to-action" for project teams to get someone to look into their specific projects? How can we go about community wide collaboration? I've created a document [1] that I assembled from AI analysis of part of the OpenStack code. It gives an overall view of the problem we face. Looking forward to hearing from you and collaborating upstream to improve OpenStack. Regards, Jean-Philippe (JP) Jung jjung(a)redhat.com irc: jjung [0] Quantum what? Quantum computers will break current encryption algorithms like RSA and elliptic curve cryptography using Shor's algorithm, exposing all data encrypted today. Adversaries are already harvesting encrypted data to decrypt later once quantum computers mature. OpenStack powers critical cloud infrastructure globally. Deploying post-quantum cryptography (PQC) upstream is essential because downstream distributions and deployments inherit these security foundations. Without upstream PQC integration, the entire OpenStack ecosystem remains vulnerable, putting sensitive workloads, government systems, and enterprise data at risk. The migration takes years, so implementing PQC now in the codebase is operationally necessary, not optional. [1] https://wiki.openstack.org/wiki/Post_quantum_openstack

Hi Neutrinos and stackers, I have added a rough schedule to our etherpad [0] for next week's vPTG meetings, please check it and make sure the times work if you had added a topic. Based on my estimates we will only meet on Tuesday and Wednesday and not have anything on Thursday, subject to change based on how long discussions take. There are cross-projects with Ironic and Nova on Wednesday. Room info is all at [1]. See you then, -Brian [0] https://etherpad.opendev.org/p/oct2025-ptg-neutron [1] https://ptg.opendev.org/ptg.html

[all][dev][ops][tc] Bridging the gap between community and contributing orgs
by Jeremy Stanley 24 Oct '25

24 Oct '25

The tl;dr on this is that I'm opening a broad community discussion on how we can, collectively through improved communication, better bring together our established contributors with casual and prospective contributors who struggle to find successful patterns of contribution, so that we might all support each other in order to benefit OpenStack as a whole. Read on for details... OpenStack's TC has requested that foundation staff, when in conversation with representatives of member organizations, encourage participation in the project and collect feedback on any related challenges those organizations encounter in their attempts to do so. In order to better understand the feedback and brainstorm achievable recommendations for the broader community[*], Community Managers on the foundation staff started to work with a small focus group of established contributors with a solid understanding of what successful patterns of contribution look like. It also came to light that established contributors experience many of the same sorts of challenges, even more so if they don't have the luxury of focusing full-time upstream, and so success often comes down to knowing how to effectively navigate those challenges. The community's goal with this exercise is to improve everyone's experience, and your help is needed to do that! The most common themes reported by those struggling to contribute are not related to tooling or workflow confusion, but instead seem to come down to basic communication challenges. Ideas so far to address these gaps include: * Review bandwidth - Ensure contributors and companies understand the importance and benefits of code review - Incentivize and credit meaningful "+1" reviews more - Understand that the volume of changes and limited reviewer bandwidth often means proposals aren't reviewed quickly (or at all), and their proponents may need some additional tenacity and engagement with the team to get their work noticed - Utilize "review dashboards" as a way to find stale changes which have fallen through the cracks * Review strategy and etiquette - Be clear about the meaning of votes on changes, especially negative ones, and set explicit timelines for things like "procedural -2" or WIP blocks when their approval needs to be delayed - Focus on comments and requests that affect whether or not the change can be merged after the fixes are submitted, rather than requesting trivial adjustments to an unsuitable change which has more fundamental problems - Reciprocate with reviews of changes from new reviewers you see leaving insubstantial reviews, demonstrating to them what deeper and more meaningful reviewing looks like * Mentoring newcomers - Established contributors with sufficient bandwidth can help mentoring newcomers, potential core reviewers and new leaders - Mentoring can happen as part of internship programs as well as by helping newcomers determined to become active contributors; both ways should be embraced and utilized What challenges are you facing? And, how would you improve them? Two weeks from now, we'll have a forum session at the OpenInfra Summit Asia in Suwon[**] where our community can refine these possible approaches and integrate others, as well as bring attention to them and promote their application. I've also proposed a similar forum session for OpenInfra Days North America in Indianapolis a month after that, where we can hopefully continue this conversation. The goal for this multi-stage effort is to improve the contribution experience for established participants, casual contributors and newcomers alike. While it's easy to jump to blaming in these situations, it will be far more productive if we can focus on the challenges and experiences that we would each like to remove or improve for ourselves and others in our community. As we find ways together to improve our efficiency, we can reduce the load on all contributors and lower the barriers for people to join and participate.

[cinder] PTG reminder and schedule
by Jon Bernard 24 Oct '25

24 Oct '25

Hello all, We covered the schedule [1] in this week's meeting but I wanted to post it here for reference. We will be meeting Tuesday, Wednesday, Thursday, and Friday of this week starting at 14:00 UTC. We technically have 4 hours each day to cover topics. Historically we have not needed all of that time, so I expect there will be some variability in end time. Two notable things to keep in mind: * We begin on Tuesday, not Monday - though there are some other sessions that day you may find interesting. See [2] for the full schedule * We have 4 cross team sessions with Eventlet, Nova, Glance, and Ironic. Keep those time slots in mind of those topics are of interest to you. Hope to see you all there!

Hi All, I'm putting "fresh" in quotes becuase I expect the issue is some home my deploy isn't as fresh as I belive it to be. I did have and older test environment which was serveral steps behind (and not quite workign for other reasons).

My deploy host wasn't reinstalled but I did delete and recreate the venv. Using Ubuntu 24.04 as the base OS Where do I go from here to find my wrong turn?

[nova] Persistent PXE boot for VMs
by Eugen Block 22 Oct '25

22 Oct '25

Good morning, we have the requirement to let a subset of VMs always boot in PXE mode. They're managed by a Uyuni server that controls whether a VM has to be (re)installed or if it should boot from local disk. I've been searching and testing, but to no avail yet, except for modifying the xml file which will not persist [0]. Is there a known history why this isn't possible (yet) or has this already been discussed and the decision was to not implement such a feature? We're thinking about implementing a solution for us, but would be also interested if a PR would have a chance to be accepted. If anyone has some insights/ideas/recommendations, I'd appreciate it. Thanks! Eugen [0] https://blog.dachary.org/2012/10/08/network-boot-an-openstack-instance/

[oslo][messaging] Container fix of QManager breaks it for containers
by Dmitriy Rabotyagov 22 Oct '25

22 Oct '25

Hey folks, I wanted to raise attention to a relatively old issue, which has had a patch around since January [1]. Basically a regression [2] was introduced and backported to 2024.1 as part of an attempt to fix QManager execution in containers. However, it does not account for the possibility of os.getpgrp() returning 0 in some edge cases, which makes, for instance, impossible to sync database for Nova during upgrades, if QManager is used. Thus I'm asking to kindly review the [1] as it appears to be a blocker for some upgrades involving affected versions of oslo.messaging. I have not spotted this patch right away, so I proposed an alternative [3], but I'm happy to abandon it in favor of [1]. Thanks in advance for upcoming reviews :) [1] https://review.opendev.org/c/openstack/oslo.messaging/+/939540 [2] https://review.opendev.org/c/openstack/oslo.messaging/+/928034 [3] https://review.opendev.org/c/openstack/oslo.messaging/+/958528

[nova] [nova-scheduler] Performance Issue with CPU Pinning Scheduling and Duplicate IPs
by İzzettin Erdem 22 Oct '25

22 Oct '25

Hi, In our environment (Kolla-Ansible Ussuri, 1200+ hypervisors), we are experiencing performance issues during bulk VM deployments. When launching around 100 VMs, the operation takes approximately *15 minutes*. During this time, the *nova-scheduler* spends over *15 minutes calculating available pinned CPUs*. However, in our Yoga production deployment, the same operation is about *10 times faster* — around *1–2 minutes* for 100 VMs. Additionally, after the 100 VMs are created, we have observed that some instances could not be created and some of the rest receive *multiple (2–3) IP addresses* from Neutron instead of one. Our nova services are running in a *NUMA-aware, CPU-pinning* configuration, and other settings are almost identical to the default configuration. Below is an excerpt from the nova-scheduler logs during VM creation (this message is repeated thousands of times within 15 minutes): Computed NUMA topology CPU pinning: usable pCPUs: [[26, 90], [89, 25], [24, 88], [27, 91], [29, 93], [10, 74], [86, 22], [28, 92], [73, 9], [23, 87], [8, 72], [18, 82], [94, 30], [81, 17], [31, 95]], vCPUs mapping: [(0, 26), (1, 90), (2, 89), (3, 25), (4, 24), (5, 88), (6, 27), (7, 91), (8, 29), (9, 93), (10, 10), (11, 74), (12, 86), (13, 22), (14, 28)] Do you have any suggestions on what might be causing: 1. The scheduler to spend so much time calculating pinned CPUs in Yoga, and 2. Some VMs to get multiple IPs from Neutron after creation? Any guidance would be greatly appreciated. Best regards, İzzettin

[kolla-ansible] [nova] Database connection points to nova cell db
by İzzettin Erdem 22 Oct '25

22 Oct '25

Hi, In Kolla-Ansible deployments, the connection parameter under the [database] section in the nova.conf template points to the *nova_cell* database [1] <https://opendev.org/openstack/kolla-ansible/src/commit/4e3208b16c452d1cf2cd…>. As far as I understand, the *nova_cell* database is primarily used to store failed operations. I was wondering: if we are not using a multi-cell architecture, should the connection instead point directly to the *nova* database rather than *nova_cell*? There was an open bug related to this issue almost a year ago, but it has not received any updates yet [2] <https://bugs.launchpad.net/kolla-ansible/+bug/2088264>. Could you please confirm whether the current configuration is correct? We have deployed OpenStack using the existing configuration and it is currently running in production. If we change the database connection in the running environment, would that cause any issues? Thank you for your time and assistance. Best regards, İzzettin

Having 2 production sites, we have observer that the Nova scheduler is allocating virtual machines (VMs) only on a single NUMA socket of the compute host. Since the flavor does not include the property hw:numa_nodes='2', vCPUs spread on two NUMA nodes scheduling is not enabled. As a result, all vCPUs and memory for a VM are placed on a single NUMA node, while the other NUMA socket(s) remain underutilized. So we tested this property in our test flavor and found that now scheduler is able to spread vcpu/vm across two numa sockets but performance on memory side is degraded for about 20% to 30%. So we are looking for suggestions on this if there is better way to accommodate more VMs or spread vcpu on two numa socket without having performance issues on memory or cpu side, or something which have less impact? Regards Brijesh

[Caracal]Optimizing Nova NUMA Scheduling Behavior (Single vs Dual NUMA Socket Allocation)
by Vish Mudemela 21 Oct '25

21 Oct '25

Hi Team, We are using Kolla Ansible for our OpenStack Caracal (2024.1) deployment across two production sites. We have observed that the Nova scheduler is currently allocating virtual machines (VMs) only on a single NUMA socket of the compute host. Since our flavors do not include the property hw:numa_nodes='2', the scheduler places all vCPUs and memory for a VM on a single NUMA node, leaving the other NUMA socket(s) underutilized. In our testing, we added the hw:numa_nodes='2' property to the flavor and confirmed that the scheduler can now distribute vCPUs across both NUMA sockets. However, this configuration led to 20–30% memory performance degradation, likely due to cross-NUMA memory access. We also noticed that once this property is set, the scheduler always attempts to spread vCPUs across two NUMA sockets — even when there are sufficient resources available on a single NUMA node. We are looking for a way to achieve conditional NUMA placement — ideally: - If a single NUMA node has enough capacity, schedule the VM entirely on that node. - Otherwise, allow the scheduler to spread the VM across multiple NUMA nodes. We would appreciate any suggestions or best practices to: Improve NUMA-aware scheduling efficiency,Better utilize both NUMA sockets without significant memory performance penalties, andAvoid forcing cross-NUMA allocation unless necessary. Has anyone in the community implemented or tuned Nova in a way that balances these requirements effectively? Thanks in advance for your insights and recommendations. Thanks

[Ceph Tracing] Limited Jaeger traces for OSD, no MON/MGR/RGW
by Thamanna Farhath 21 Oct '25

21 Oct '25

Hi Ceph Team, We’ve enabled Jaeger tracing in our Ceph cluster using: ceph config set global jaeger_tracing_enable true Currently, only OSD traces (e.g., enqueue_op, op-request-created) are visible, while MON, MGR, and RGW traces are missing. I noticed PR https://github.com/ceph/ceph/pull/59365 adds more tracers but hasn’t been merged yet. Could you please confirm: If this is an ongoing bug or current limitation? Whether there’s an alternative branch, backport, or workaround to achieve full tracing coverage? Appreciate your guidance.

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2026.1/R-23)
by Goutham Pacha Ravi 20 Oct '25

20 Oct '25

Hello Stackers, Over the weekend, the OpenInfra Summit in Paris-Saclay wrapped up. From what I heard, it was a successful event with a lot to unpack for the entire community. We'll discuss the summit over trip reports and activity across and within project teams over the coming weeks. We're twenty-three weeks away from the coordinated release of OpenStack 2026.1 "Gazpacho" [1]. Next week, the OpenStack community will be participating in the OpenInfra Virtual Project Teams Gathering (PTG). Project teams are grooming discussion topics on Etherpads [2]. The OpenStack Technical Committee will be meeting alongside project teams [3], and we'll kick off discussions as we've usually done by meeting with project maintainers. All project team leads, DPL liaisons, and core maintainers are invited to attend, and brainstorm community-wide concerns during this time slot. This event will be held at 1600 UTC on Tuesday, October 28th, 2025. Please see the PTG website for the call information, and better yet, pop into the #openinfra-events IRC channel on OFTC for real-time updates from all project discussions throughout the week. If you haven't already registered for the event, please do so [4]. This past week was a busy week for the community and the OpenStack Technical Committee. The "ironic-inspector" repositories were removed, and all the functionality provided has long been integrated into Ironic. Michał Nasiadka (mnasiadka) volunteered to be the TC liaison for the Requirements and Release Management teams. The TC also marked the Vitrage and Venus project teams as "inactive" [5]. These project teams need help. If you're a maintainer, contributor, or user, please help us re-form the project teams by determining project leadership and fixing up any failing CI jobs. All deliverables associated with these project teams will be dropped from the 2026.1 "Gazpacho" release cycle. If activity does not resume, we'll retire the deliverables and the respective project teams in the 2026.2 release cycle. This week, the TC will begin our first monthly meeting at an APAC-friendly time! As a globally distributed community, our preferred mantra of communication is asynchronous; however, once in a while, sync meetings help us make progress, and we'll try to cater to as many different timezones as possible. For now, on every third Tuesday of the month, we'll meet at 0800 UTC (instead of 1700 UTC) in the #openstack-tc channel on OFTC. At the same time, we'll be stopping our Video + IRC meeting for the rest of this release development cycle. Please download the meeting's ICS file and update your calendars [6]. === Weekly Meeting === The last weekly meeting of the OpenStack Technical Committee occurred on October 14th, 2025 [7]. The TC discussed several outstanding governance changes and gathered the roll call votes needed to mark Vitrage and Venus project teams inactive. We reiterated that the proposal to retire the Monasca project is still pending, but a current maintainer needs assistance with the release process, and Elod Illes (elodilles) would walk them through it. Michał Nasiadka (mnasiadka) volunteered to be the TC liaison for the Requirements and Release Management project teams. The TC agreed to sunset scheduled video meetings, opting to bring them back only on an ad-hoc basis due to lack of interest. The remaining portion of the meeting focused on establishing a new, more EU/APAC-friendly meeting time. We decided on doing this monthly on the third Tuesday at 08:00–09:00 UTC, replacing the regular 17:00 UTC slot for that day. We also called for topics for the upcoming PTG (Project Team Gathering) [3] and briefly reviewed the runtime and job changes for the Gazpacho release, which includes making the Python 3.13 job voting, creating a non-voting Python 3.14 job, and fixing up the grenade templates [8]. The next meeting of the TC is on October 21st, 2025, at 0800 UTC. This meeting will be hosted in the #openstack-tc channel on OFTC, and mnasiadka will be chairing it. Please find the agenda on the meeting's wiki page [9]. Please chime in and say hi. I do hope this new meeting slot is feasible for contributors in the Eastern Hemisphere. Do remember, you can always edit the wiki and propose new meeting topics. === Governance Proposals === ==== Merged ==== - Update TC liaisons for Freezer and Oslo | https://review.opendev.org/c/openstack/governance/+/964257 - Retire ironic-inspector from bare metal program | https://review.opendev.org/c/openstack/governance/+/963470 - Mark Vitrage project team inactive | https://review.opendev.org/c/openstack/governance/+/963227 - Mark Venus project team inactive | https://review.opendev.org/c/openstack/governance/+/963228 - Propose mnasiadka as tc-liaison for Requirements and Release Management | https://review.opendev.org/c/openstack/governance/+/963989 ==== Open For Review ==== - Require declaration of affiliation from TC Candidates | https://review.opendev.org/c/openstack/governance/+/949432 - Retire Monasca project | https://review.opendev.org/c/openstack/governance/+/953671 === Upcoming Events === - 2025-10-22: OpenInfra Meetup, Jakarta Selatan: https://www.meetup.com/openinfraid/events/31140538 - 2025-10-27: OpenInfra PTG: https://openinfra.org/ptg/ - 2025-11-04: OpenInfra Board meeting: https://board.openinfra.org/ - 2025-11-15: Celebrating 15 years of OpenStack, Montréal - 2025-11-15: KCD + OpenInfra Days, Hangzhou: https://sessionize.com/kcd-hangzhou-and-oicd-2025/ === How to Contact the TC === You can reach the TC in several ways: 1.

[PTG] Glance cross-project sessions with Cinder/Nova
by Cyril Roelandt 20 Oct '25

20 Oct '25

Hello, We would like to host two cross-project sessions regarding the following topics: - Image encryption and disk format enforcement[1]: this has implicatoins for both Nova and Cinder. This should probably be a one hour session. - Make multiattach workflow compatible with multiple glance workers: this is related to both Cinder and Glance. This could be a half hour or full hour session, depending on what Rajat has in mind. Glance is very flexible with its scheduling: we will be busy during the eventlet session on Tuesday between 15:00 UTC and 16:00 UTC, otherwise we're pretty much free every day between 13:00 UTC and 17:00 UTC. Ideally we would host these sessions on Wednesday or Thursday. What would work for members of the Nova and Cinder teams? On behalf of the Glance team, Cyril Roelandt [1] https://etherpad.opendev.org/p/2026.1-ptg-glance-planning#L128 [2] https://etherpad.opendev.org/p/2026.1-ptg-glance-planning#L140

[kolla][kolla-ansible] Contributing to a Gerrit change not owned by me
by sarah.kh09＠gmail.com 19 Oct '25

19 Oct '25

Hi everyone, I have a question about contributing to an existing change in Gerrit. Is it possible to propose additional commits or modifications to a change that I do not own (i.e., a change created by another contributor), so that my update will appear as a new patch set on the same change, not as a separate one? If yes, what’s the recommended workflow or best practice to do this in the Kolla Ansible project? Also, do I just need the approval or agreement of the change owner before pushing my patch set, or are there any other formal steps required? Thanks in advance for your guidance!

[nova][sdk] Compute host query filter on list servers
by Winicius Allan 17 Oct '25

17 Oct '25

When building a script that utilizes openstacksdk, I encountered a problem while filtering servers by compute host. According to the documentation[1], I need to refer to the Compute API to find the available query parameters. On the API docs, the proper query param is just `host` instead of compute_host. I raised a discussion in[2]. I'd like to know the maintainers' opinions on this, and the decisions made.

[Octavia][Load Balancer][2023.1] Amphora Fails Health Check – “No Route to Host” & Timeout Errors
by Thamanna Farhath 15 Oct '25

15 Oct '25

Hi OpenStack Community, I am currently facing an issue with the Load Balancer (Octavia) service in my OpenStack deployment and would appreciate your guidance or suggestions on how to troubleshoot and resolve it. Environment Details: OpenStack Version: 2023.1 (Antelope) Operating System: Ubuntu 22.04 Octavia Backend: Amphora Network Type: VXLAN Deployment Tool: Kolla Ansible Issue Summary: After creating a Load Balancer, the Amphora instance is successfully launched. However, approximately 18 minutes later, the Load Balancer transitions to an ERROR state. Error Observed: octavia.common.exceptions.ComputeWaitTimeoutException: Waiting for compute id a222527f-8336-4fb1-8e9e-0e3ac6e8d580 to go active timeout. octavia.amphorae.driver_exceptions.exceptions.AmpConnectionRetry: Could not connect to amphora, exception caught: HTTPSConnectionPool(host='192.168.200.247', port=9443): Max retries exceeded with url: // (Caused by NewConnectionError: Failed to establish a new connection: [Errno 113] No route to host) What I’ve Tried: Created a VXLAN-based internal network: openstack subnet create --network octavia-mgmt-net --subnet-range 192.168.200.0/24 octavia-mgmt-subnet openstack router create octavia-router openstack router add subnet octavia-router octavia-mgmt-subnet openstack router set octavia-router --external-gateway <public-network-id> Manually configured OVS interface: ovs-vsctl add-port br-int octavia-mgmt -- set interface octavia-mgmt type=internal ip addr add 192.168.200.1/24 dev octavia-mgmt ip link set octavia-mgmt up Security groups are open (allowing all ingress and egress).

The controller cannot reach the Amphora management IP (192.168.200.x). Logs show heartbeat/connection issues (No route to host, timeouts). Request for Help: I would appreciate any of the following: Suggestions to verify if the management network is properly routed from controller to Amphora. Best practices for setting up the Octavia management network using VXLAN. Troubleshooting steps for verifying health manager connectivity to Amphora.

I'm going to find a way if possible, to set the admin password during the "server create". Currently the root login is only possible with password "q". The "ahmad" is not working. I know I can change it via user-data file (I intentionally added there but not using it), but the question is can I set the password during the server create? I tried to use "virt-customize --install qemu-guest-agent", but the virt-customize has no network, so no installation. I also know I can do this: 1. create server 2. do whatever I want (install guest agent, etc) 3. create snapshot 4. create server from that snapshot But the issue is it's not automatic (I should manually login to do the modification) and its size is much more than the cloud image. Like, from 500 megabytes which is cloud image, goes around 3 gigabytes which is the snapshot. Any ways to reach what I'm looking for? Or even any better ways to do that? Regards, Ahmad

Dear Openstack community, I'm wondering if there are any plans to support sk-ssh-ed25519(a)openssh.com SSH public key formats for the keypairs endpoint. I did not find in the public documentation any explicit information about supported SSH public keys, but according to my experiences the mentioned format is not accepted. Did I miss something? Is it supported in any recent versions? Is it on the roadmap? Thank you all for any reply! Best regards, Ivan Marton

Hello openstack Community, I am using Ceph as the backend storage for OpenStack and deployed it via ceph-ansible.I enabled Jaeger tracing on Ceph cluster using: - Global Ceph config: ceph config set global jaeger_tracing_enable true - Jaeger Docker all-in-one docker run -d --name jaeger -e COLLECTOR_ZIPKIN_HOST_PORT=:9411 -e COLLECTOR_OTLP_ENABLED=true --network host -p 6799:6799/udp -p 6832:6832/udp -p 5778:5778 -p 16686:16686 -p 4317:4317-p 4318:4318 -p 14250:14250 -p 14268:14268 -p 14269:14269 -p 9411:9411 jaegertracing/all-in-one:1.27 --processor.jaeger-compact.server-host-port=6799 Issue: - Only OSD traces appear with limitation traces(`enqueue_op`, `op-request-created`) - No traces from MON, MGR, or RGW Questions: 1. Is this the correct process for enabling tracing? 2. How can I capture traces for MON, MGR, RGW? 3. How can I see all OSD operations?

How to set admin password during server create but not using user-data file
by Ahmad Milad Pour 13 Oct '25

13 Oct '25

Hello there, This is how I download an ubuntu cloud image: wget -c https://cloud-images.ubuntu.com/noble/current/noble-server-cloudimg-amd64.i… -O ~/noble-server-cloudimg-amd64.img virt-customize -a noble-server-cloudimg-amd64.img \ --timezone Asia/Tehran \ --root-password password:q \ --run-command 'sed -i "s/^disable_root.*/disable_root: false/" /etc/cloud/cloud.cfg' \ --run-command 'grep -q "^ssh_pwauth:" /etc/cloud/cloud.cfg && sed -i "s/^ssh_pwauth:.*/ssh_pwauth: true/" /etc/cloud/cloud.cfg || echo "ssh_pwauth: true" >> /etc/cloud/cloud.cfg' \ --run-command 'printf "PasswordAuthentication yes\nPermitRootLogin yes\n" > /etc/ssh/sshd_config.d/99-allow-root.conf' \ --run-command "sed -e 's/^[# ]*PasswordAuthentication.*/PasswordAuthentication yes/g' -i /etc/ssh/sshd_config || true" \ --run-command "sed -e 's/^[# ]*PermitRootLogin.*/PermitRootLogin yes/g' -i /etc/ssh/sshd_config || true" \ --run-command 'systemctl enable ssh || systemctl enable sshd' \ --run-command 'systemctl disable systemd-networkd-wait-online.service' openstack image create --file ~/noble-server-cloudimg-amd64.img --disk-format qcow2 --container-format bare --public --property os_distro=ubuntu --property hw_qemu_guest_agent=yes "Ubuntu 24" || true rm -f noble-server-cloudimg-amd64.img cat <<EOF > /root/userdata.txt #cloud-config chpasswd: list: | root:q expire: False ssh_pwauth: True cmd: - systemctl disable systemd-networkd-wait-online.service EOF openstack server create --image "Ubuntu 24" --flavor first --network public_network --config-drive True ahmad --password 'ahmad' This is how I create image. I'm going to find a way if possible, to set the admin password during the "server create". Currently the root login is only possible with password "q". The "ahmad" is not working. I know I can change it via user-data file (I intentionally added there but not using it), but the question is can I set the password during the server create? I tried to use "virt-customize --install qemu-guest-agent", but the virt-customize has no network, so no installation. I also know I can do this: 1. create server 2. do whatever I want (install guest agent, etc) 3. create snapshot 4. create server from that snapshot But the issue is it's not automatic (I should manually login to do the modification) and its size is much more than the cloud image. Like, from 500 megabytes which is cloud image, goes around 3 gigabytes which is the snapshot. Any ways to reach what I'm looking for? Or even any better ways to do that? Regards, Ahmad

[ovn][wallaby][migration] Live migration more than 10s switchover
by Kamil Madac 13 Oct '25

13 Oct '25

Hello community, We are running a Wallaby TripleO installation with OVN networking. During live migration, we’re experiencing a connectivity outage lasting between *10 and 40 seconds* on the provider network to which the migrating VM is connected. I don’t see any errors in the ovn-controller, nova, or neutron logs. Is this behavior normal for the Wallaby release? We don’t see this issue in our Kolla-Ansible deployment running OpenStack 2024.2. I found that OVN multi-chassis port bindings were not yet implemented in Wallaby, but still — more than 10 seconds of downtime during live migration seems excessive. Has anyone observed similar behavior with older OpenStack releases, or is there any way to tune or optimize the switchover to reduce the outage duration? Thanks for any advice. Best regards, Kamil

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2026.1/R-24)
by Goutham Pacha Ravi 13 Oct '25

13 Oct '25

Hello Stackers, We're twenty-four weeks away from the coordinated release of OpenStack 2026.1 "Gazpacho" [1]. In a couple of weeks, the community will be gathering to design and discuss features and bug fixes for this release [2]. PTLs and project liaisons are requested to finalize their project schedules for the PTG and strive to use the first two days solely for wider cross-project discussions. At the end of this week, a portion of our community will be participating in the OpenInfra Summit happening at the École Polytechnique Campus in Paris-Saclay, France [3]. There's a meet-and-greet session planned with the OpenStack Technical Committee on Sunday, October 19th starting at 17:05 UTC in the Becquerel room. If you're attending the summit, do try to add this to your calendar. During the past week, the TC didn't make any major governance updates. A few are currently undergoing community review. === Weekly Meeting === The last weekly meeting of the OpenStack TC occurred on October 7th, 2025 simultaneously over IRC [4] and video [5]. We had a small list of attendees and a short agenda. We noted that the governance changes to officially mark Venus and Vitrage as inactive are in progress. The retirement of Monasca is still held up, and the team is waiting for a response from a potential new maintainer. Discussions were held on the new APAC-friendly TC meeting slot, with the plan to review the poll results and schedule the first meeting shortly after the OpenStack Summit, likely on a monthly or bi-weekly cadence. I'll follow up with more details about this. We also discussed the need to refresh the TC Liaisons for several project teams (Freezer, Oslo, Release Management, and Requirements) and are seeking volunteers on the TC. We called for topics for the PTG. The TC will join project teams in analyzing the User Survey results [6]. The next meeting of the OpenStack Technical Committee will be hosted on OFTC's #openstack-tc channel on October 14th, 2025 at 1700 UTC. Please find the agenda for this meeting on the wiki [7]. I hope you're able to join us there. === Governance Proposals === ==== Merged ==== - Allow .gitignore in legacy repositories | https://review.opendev.org/c/openstack/governance/+/963867 - Retire metalsmith project from bare metal program | https://review.opendev.org/c/openstack/governance/+/958297 ==== Open For Review ==== - Mark Vitrage project-team inactive | https://review.opendev.org/c/openstack/governance/+/963227 - Mark Venus project-team inactive | https://review.opendev.org/c/openstack/governance/+/963228 - Retire ironic-inspector from bare metal program | https://review.opendev.org/c/openstack/governance/+/963470 - Retire Monasca project | https://review.opendev.org/c/openstack/governance/+/953671 - Require declaration of affiliation from TC Candidates | https://review.opendev.org/c/openstack/governance/+/949432 === Upcoming Events === - 2025-10-17: OpenInfra Summit, Paris-Saclay: https://summit2025.openinfra.org/ - 2025-10-22: OpenInfra Meetup, Jakarta Selatan: https://www.meetup.com/openinfraid/events/31140538 - 2025-10-27: OpenInfra PTG: https://openinfra.org/ptg/ - 2025-11-04: OpenInfra Board meeting: https://board.openinfra.org/ - 2025-11-15: Celebrating 15 years of OpenStack, Montréal - 2025-11-15: KCD+OpenInfra Days, Hangzhou: https://sessionize.com/kcd-hangzhou-and-oicd-2025/ Thank you very much for reading!
