[openstack-helm] Inquiry: OpenStack-Helm Deployment in Production Environments
by Thamanna Farhath 07 Mar '25

07 Mar '25

Hello OpenStack Community, I hope this email finds you well. I am currently exploring OpenStack-Helm for deploying OpenStack and would like to understand its adoption in live production environments. Specifically, I am interested in knowing if any cloud providers have successfully deployed and are operating OpenStack using OpenStack-Helm in production. If there are any case studies, references, or experiences shared by operators who have implemented this deployment method, I would greatly appreciate any insights or guidance. Looking forward to your valuable input.

Hi Everyone, I have the 2024.1 Caracal multi node setup working. Now I am trying to enable SRIOV on this setup by following the below link, https://docs.openstack.org/neutron/2024.1/admin/config-sriov.html Observing the below issue while running the “neutron-sriov-agent” service on compute node and it is restarting on every 2 seconds. Kindly let me know if I need to enable any configs specific to “neutron-sriov-agent” service. # tail -f /var/log/neutron/neutron-sriov-agent.log 2025-03-06 15:02:42.968 9311 INFO neutron.common.config [-] Logging enabled! 2025-03-06 15:02:42.969 9311 INFO neutron.common.config [-] /usr/bin/neutron-sriov-nic-agent version 24.0.0 2025-03-06 15:02:42.969 9311 DEBUG neutron.common.config [-] command line: /usr/bin/neutron-sriov-nic-agent --config-file=/etc/neutron/neutron.conf --config-file=/etc/neutron/plugins/ml2/sriov_agent.ini --log-file=/var/log/neutron/neutron-sriov-agent.log setup_logging /usr/lib/python3/dist-packages/neutron/common/config.py:123 2025-03-06 15:02:42.970 9311 DEBUG neutron.agent.common.utils [-] Std library socket module is patched by eventlet.

[neutron] Drivers meeting canceled Friday, March 7th
by Brian Haley 06 Mar '25

06 Mar '25

Hello Neutrinos: I'm going to cancel tomorrow's drivers meeting as discussed at this week's team meeting, since we are past feature freeze and should be focusing on getting in-flight things merged and bug fixes. Just a reminder there are still open specs that need review, list is at [0]. And just a reminder I am offline until next Tuesday. Have a nice weekend! -Brian [0] https://review.opendev.org/q/status:open+project:openstack/neutron-specs

Assistance Required: OpenStack Helm Deployment (Version 2023.1) Compatibility Issues
by Thamanna Farhath 05 Mar '25

05 Mar '25

Hello OpenStack Community, I hope you are doing well. I am currently deploying OpenStack on top of a Kubernetes cluster using OpenStack Helm and aiming to install the 2023.1 (Antelope) version. However, I am facing difficulties in installing this specific version via Helm charts. Despite my attempts, I have not been able to successfully deploy the required OpenStack services for this release. Additionally, I am ensuring that the dependent services, such as RabbitMQ, align with the compatibility requirements of OpenStack 2023.1. As per the OpenStack documentation, RabbitMQ 3.11 is the recommended version, but I encountered issues while deploying it. Instead, I found that RabbitMQ 3.12 works without any issues. I would like to know: Is there a way to install OpenStack 2023.1 properly using Helm charts, or should I consider using a newer OpenStack version? Will using RabbitMQ 3.12 instead of 3.11 cause any potential issues with OpenStack services, or is it safe to proceed with this version? Are there any known workarounds or recommendations for deploying OpenStack 2023.1 using Helm? I would appreciate any guidance, best practices, or documentation references that could help resolve these challenges. Looking forward to your valuable insights.

[neutron] LXB Removal and OVN migration
by Ricardo Cano 04 Mar '25

04 Mar '25

Hello openstack-discuss, With the removal of the linuxbridge mechanism driver, has anyone successfully completed an in-place migrationfrom LinuxBridge to OVN? I did come across this https://www.jimmdenton.com/migrating-lxb-to-ovn/ and that looks good as a one-shoit while biting the bullet and taking a full outage. However, I was wondering if it was possible to run lxb and ovn side-by-side and cut them over, say one network at a time. This particular deployment was stood up using openstack-ansible back in the rocky days (now running antelope) and it appears that openstack ansible's default was lxb up until Zed. Any suggestions or recommendations on the best path forward? Also, will the dynamic routing agent work with ovn?

I did come across this https://www.jimmdenton.com/migrating-lxb-to-ovn/ and that looks good as a one-shoit while biting the bullet and taking a full outage. However, I was wondering if it was possible to run lxb and ovn side-by-side and cut them over, say one network at a time. This particular deployment was stood up using openstack-ansible back in the rocky days (now running antelope) and it appears that openstack ansible's default was lxb up until Zed. Any suggestions or recommendations on the best path forward? Also, will the dynamic routing agent work with ovn?

Dear Mentors, I have good experience in building openstack in multiple environments bare-metal, kolla-ansible and helm project for minimal deployment to good HA clusters. Now, I'm looking to get into code level and contribute to open-infra foundation. I'm not a someone beginner to coding, I have done programming in a good amount and hold a knowledge of paradigm and principles. Here's my github: https://github.com/jamesii-b I'm looking for mentor who can guide me what to do as a Contribution.. Even deploying first openstack is overwhelming on its own, Coding is more. Please have me. Trust me, I'll have utmost respect to your time and energy and get most of it. Knowledge I have: HPC, Openstack Deployment, Network & System, Parallel Programming, Python, Rust.
