[all][dev][ops][tc] Bridging the gap between community and contributing orgs
by Jeremy Stanley 16 Jun '25

16 Jun '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.

[manila] Removal of the Standalone CephFS NFS protocol helper in Epoxy
by Ashley Rodriguez 02 May '25

02 May '25

Hi zorillas! As per subject line, we will be deprecating the standalone CephFS NFS protocol helper in this cycle. This is following our deprecation warning we put out in 2024.1 / Caracal [1] [2]. We've supported using a clustered Ceph NFS service since the Zed release. We've also added upgrade helpers to migrate from a standalone NFS-Ganesha service to the ceph-orch-deployed clustered NFS service; this code was backported to stable/2023.1 (Antelope). Although the upgrade path is disruptive, there is a UX improvement in Manila to ease this migration through surfacing “preferred” export paths. Moving forward, deployments must have “cephfs_nfs_cluster_id” in your configuration, otherwise the driver will fail to start. Manila will not make any export changes to NFS-Ganesha, so upgrading manila without an NFS cluster will mean that only the control plane is not going to work; but, data plane will remain unaffected. To assist migration, admins can also configure "cephfs_ganesha_export_ips" (or alternatively, "cephfs_ganesha_server_ip") alongside "cephfs_nfs_cluster_id". Setting these options will allow the CephFS driver to report additional export paths. These additional export paths will have the "preferred" metadata key set to False. Best, Manila team [1] https://review.opendev.org/c/openstack/manila/+/912648 [2] https://docs.openstack.org/manila/2024.2/configuration/shared-file-systems/…

Fwd: DPDK+OVS with OpenStack
by Mark Wittling 23 Apr '25

23 Apr '25

Looking for someone who knows OpenStack with OpenVSwitch, and in addition to that, DPDK with OpenStack and OVS.I am using OpenStack Queens, with OpenVSwitch. The architecture I am using is documented here: https://docs.openstack.org/neutron/queens/admin/deploy-ovs-provider.htmlThe OVS I am using on the Compute Node, is compiled with DPDK, and I have enabled the datapath to netdev (DPDK) on br-prv (provider network bridge), and br-tun (tunneling bridge). But these two bridges, br-tun and br-prv, are patched into another OpenStack bridge, called br-int. I wasn’t actually sure about whether to tinker with this bridge, and wondered what datapath it was using.Then, I realized there is a parameter in the openvswitch_agent.ini file, which I will list here: # OVS datapath to use. 'system' is the default value and corresponds to the # kernel datapath. To enable the userspace datapath set this value to 'netdev'. # (string value) # Possible values: # system - <No description provided> # netdev - <No description provided> #datapath_type = system datapath_type = netdev So in tinkering with this, what I realized, is that when you set this datapath_type to system or netdev, it will adjust the br-int bridge to that datapath type.So here is my question. How can I launch a non-DPDK VM, if all of the bridges are using the netdev datapath type?Here is another question. What if one of the flavors don’t have the largepages property set on them? I assumed OpenStack would revert to a system datapath and not use DPDK for those VM interfaces. Well, I found out in testing, that is not the case. If you set all your bridges up for netdev, and you don’t set the property on the Flavor of the VM (largepages), the VM will launch, but it simply won’t work.Is there no way, on a specific Compute Host, to support both DPDK (netdev datapaths) and non-DPDK (system datapaths)?Either on a VM interface level (VM has one interface that is netdev DPDK and another that is system datapath non-DPDK)?Or on a VM by VM basis (VM 1 has 1 or more netdev datapath interfaces and VM 2 has 1 or more system datapath interfaces)?Am I right here? Once you set up a Compute Host for DPDK, it’s DPDK or nothing on that Compute Host? (edited)

How to config DPDK compute in OVN
by dangerzone ar 22 Apr '25

22 Apr '25

Hi....as far I understand ovs does support dpdk compute to be deployed. I'm referring to the guideline ' *https://docs.openstack.org/networking-ovn/queens/admin/dpdk.html <https://docs.openstack.org/networking-ovn/queens/admin/dpdk.html>* ' ... It's too brief.. May I know how to config dpdk compute in OVN networking openstack? Hope someone could help what is the config to be done.... Currently compute is run without dpdk over openstack train ovn based. Please need some info on how I can proceed. Thank you

[oslo] python-consul2 is unmaintained
by Takashi Kajinami 21 Apr '25

21 Apr '25

Hello, I recently noticed that python-consul2 library[1], which is used by the consul coordination driver in tooz, hasn't been updated for 3+ years. Looking at issues in the project, there is an indication that the library is not compatible with ACL API in consul >= 1.11[2]. There is another fork created[3] and this includes fixes to support new API endpoints. Although the driver in tooz does not directly use the feature, I think it's better to discuss our plan to mitigate risks caused by the unmaintained library. As far as I can think of, there are three options now 1. Deprecate consul driver and remove it 2. Keep using python-consul2 now. At least basic functionality is proven to work by our functional tests (Note that the tests do not cover all configuration patterns) 3. Replace python-consul2 by py-consul Before we start the overall discussions I'd like to ask a few questions to the wider audience, as our inputs. - Is anyone using the consul coordination driver now ? - Does anyone have experience with python-consul2 and/or py-consul ? Note that this discussion affects the http messaging driver[4] currently proposed, because it also requires client library to communicate with Consul. Actually I noticed the situation when I noticed that the requirement check job is failing because the library is not part of global requirements list... Thank you, Takashi Kajinami [1] https://github.com/poppyred/python-consul2 [2] https://github.com/poppyred/python-consul2/issues/42 [3] https://github.com/criteo-forks/py-consul [4] https://review.opendev.org/c/openstack/oslo.messaging/+/912499 -- Takashi Kajinami irc: tkajinam github: https://github.com/kajinamit launchpad: https://launchpad.net/~kajinamit

Hey Folks, I could use a little assistance getting GPU passthrough working. I had this working already for one flavor of nvidia gpu... and I've added some hosts with a much newer gpu... I've updated the pci_alias and pci_passthrough variables and those seem to be getting set properly in nova.conf passthrough_whitelist = [{"vendor_id":"10de", "product_id":"1b06"},{"vendor_id":"10de", "product_id":"26b9"}] alias = {"name": "gpu", "product_id": "1b06", "vendor_id": "10de"} alias = {"name": "gpu-l40s", "product_id": "26b9", "vendor_id": "10de"} I believe I have all of the iommu stuff configured and have the pci- stub module entries... dmesg output shows that the GPUs are being claimed by the stub module. $ openstack flavor show t1.small_gpu_l40s +----------------------------+--------------------------------------+ | Field | Value | +----------------------------+--------------------------------------+ | OS-FLV-DISABLED:disabled | False | | OS-FLV-EXT-DATA:ephemeral | 0 | | access_project_ids | None | | description | None | | disk | 0 | | id | af70c94e-0026-4a39-bc1e-dfb93b286a54 | | name | t1.small_gpu_l40s | | os-flavor-access:is_public | True | | properties | pci_passthrough:alias='gpu-l40s:1' | | ram | 2048 | | rxtx_factor | 1.0 | | swap | 0 | | vcpus | 1 | +----------------------------+--------------------------------------+ Yet... I can't seem to get an instance to run using that new flavor... keeps complaining about there not being enough hosts available.

Hello Everyone, I am currently trying to setup in all-in-one development environment for OpenStack on a Debian VM. The VM has 16 GB RAM and 4 CPUs. However, I face an error while trying to run FORCE=yes ./stack.sh. I get an error that keystone does not start. This causes the entire process to fail. Requesting assistance in solving this issue. I am following the this guide: https://docs.openstack.org/devstack/latest/guides/single-machine.html PFA the error log and error message on the terminal. [Call Trace] ./stack.sh:1126:start_keystone /opt/stack/devstack/lib/keystone:549:die [ERROR] /opt/stack/devstack/lib/keystone:549 keystone did not start Error on exit World dumping... see /opt/stack/logs/worlddump-2024-11-18-150808.txt for details ovs-vsctl: unix:/var/run/openvswitch/db.sock: database connection failed (No such file or directory) ovs-vsctl: unix:/var/run/openvswitch/db.sock: database connection failed (No such file or directory) Thanks in advance, Ishan
