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

[tc][all][monasca ] Retiring the Monasca project
by Ghanshyam Mann 16 Feb '25

16 Feb '25

Hello everyone, As you might know, the Monasca project is not active and was marked 'inactive' since 2024.1 cycle[1]. In this cycle also, this project is leaderless[2] and no maintainer stepped up to maintain it. As discussed in the Leaderless project etherpad[2], the next step is to retire the project. I'm sending this email to propose the Monasca retirement and based on the response, I will proceed next.

[ironic]About the OS supported by Diskimage-builder
by Junya Noguchi (Fujitsu) 03 Feb '25

03 Feb '25

To whom it may concern. My name is Junya Noguchi. I have some questions about the supported OS for Diskimage-builder operation. Please respond. References https://docs.openstack.org/ironic-python-agent-builder/latest/admin/dib.html Does it mean that the OS that says "work but receive only limited testing and support" works but is not supported? References https://docs.openstack.org/diskimage-builder/latest/ This document describes RHEL and other operating systems that are not supported in the previous question. Are these operating systems supported? Also, are there any plans to support more operating systems in the future? Best regards, Junya Noguchi

[glance][ops] proposal to remove the glance-scrubber
by Brian Rosmaita 19 Jan '25

19 Jan '25

Hello Glance users, The Glance project team wants to determine whether anyone is using the glance-scrubber utility [0]. If not, we are thinking of deprecating it this cycle to be removed in the appropriate future cycle. If you have not previously heard of the glance-scrubber, that's most likely because it's only useful for particular deployment configurations of which yours is not one. See the doc [0] for details if you are curious. Our suspicion is that the glance-scrubber may have outlived its usefulness for modern OpenStack configurations. (The last time I remember it being discussed at a PTG was during the snowstorm in Dublin, which I believe was the Rocky development cycle). On the other hand, the team also has some ideas for improving the scrubber, but there's no point doing that if it's not actually being used in the first place. So if removal of the glance-scrubber would negatively affect you, please respond to this email so we can get some data points. Thanks!

[cinder][kubernetes] pvc stuck in reserved state
by Eugen Block 10 Jan '25

10 Jan '25

Hi, we have a couple of k8s clusters in our openstack environment (Victoria) and are facing some problems when pods get moved to different worker nodes. The PVCs get stuck in "reserved" state, and they only get attached after resetting the volumes to "available" state. First I thought it was due to the missing multiattach volume type which seems to work fine in our customer's cluster. I also found the "duplicate connector" error messages in the nova-compute.log: > Unable to update attachment.(Invalid volume: duplicate connectors > detected on volume But after adding the multiattach volume type and retyping the affected volumes, the PVCs still get stuck in "reserved" state while I don't see any error messages on the hypervisors anymore. So it seems that something has changed/improved, but now I don't have a trace where to look next. Could this be a cinder-csi driver issue or something? Our cinder backend is ceph (Pacific). Not sure which information could help so please ask for anything I can provide. Any pointers are highly appreciated! Thanks! Eugen

[ironic] Having issue with deploying ISO image to node
by James Leong 17 Nov '24

17 Nov '24

Hi all, I am trying to play around with ironic, and I am having an issue with deploying an Ubuntu 20.04 ISO image onto my bare metal node. Since I am quite new to bare metal, I am not entirely sure what went wrong as I couldn't find any error messages shown on my log file (ironic-conductor, ironic-api, ironic_neutron_agent, and nova-compute-ironic). This might be my guess; the ironic inspection is hitting timeout, which is causing the deployment to timeout. However, I have no idea why the inspection is failing at timeout. Any help would be appreciated. Best, James

Kolla Ansible on Ubuntu 20.04 - cloud-init & other network issues
by Tobias McNulty 10 Oct '24

10 Oct '24

Hi, I'm attempting to use Kolla Ansible 14.6.0 to deploy OpenStack Yoga on a small 3-node Ubuntu 20.04 cluster. The nodes have 128 GB RAM each, dual Xeon processors, and dual 10G Intel NICs. The NICs are connected to access ports on a 10G switch with separate VLANs for the local and external networks. All the playbooks run cleanly, but cloud-init is failing in the Ubuntu 20.04 and 22.04 VMs I attempt to boot. The VM images are unmodified from https://cloud-images.ubuntu.com/, and cloud-init works fine if I mount a second volume with user-data. The error is a timeout attempting to reach 169.254.169.254. This occurs both when booting a VM in an internal routed network and directly in an external network. I tried various neutron plugin agents (ovn, linuxbridge, and openvswitch both with and without firewall_driver = openvswitch <https://docs.openstack.org/kolla-ansible/latest/reference/networking/neutro…>) first with a clean install of the entire OS each time, all with the same result. Running tcpdump looking for 169.254.169.254 shows nothing. As a possible clue, the virtual NICs are unable to pass any traffic (e.g., to reach an external DHCP server) unless I completely disable port security on the interface (even if the associated security group is wide open). But disabling port security does not fix cloud-init (not to mention I don't really want to disable port security). Are there any additional requirements related to deploying OpenStack with Kolla on Ubuntu 20.04? This is a fairly vanilla configuration using the multinode inventory as a starting point. I tried to follow the Quick Start <https://docs.openstack.org/kolla-ansible/yoga/user/quickstart.html> as closely as possible; the only material difference I see is that I'm using the same 3 nodes for control + compute. I am using MAAS so it's easy to get a clean OS install on all three nodes ahead of each attempt. I plan to try again with the standard (non-HWE) kernel just in case, but otherwise I am running out of ideas. In case of any additional clues, here are my globals.yml and inventory file, along with the playbook I'm using to configure the network, images, VMs, etc., after bootstrapping the cluster: https://gist.github.com/tobiasmcnulty/7dbbdbc67abc08cbb013bf5983852ed6 Thank you in advance for any advice!

Hi all, As Python 3.13 is close to become a reality, new concerning incompatibilities between this new CPython version and Eventlet also become a reality: - https://github.com/eventlet/eventlet/issues/964 Fedora Python maintainers proposed a patch, but for now the problem remains unsolved. Also, many people reported bugs related to incompatibility between python3.12/dnspython/eventlet/pip-system-cert. There is an example who summarize well the problem https://github.com/eventlet/eventlet/issues/957 Do you have some visibility concerning the adoption of Python 3.13 into Openstack?

[Kolla] [LetsEncrypt] Internal/External/Backend Certificates
by jjjamesg＠proton.me 05 Sep '24

05 Sep '24

Hi all, another one here that can't seem to get kolla running with letsencrypt certs, just curious as to what settings are required for kolla to pull internal/external/backend certs from letsencrypt? I've looked at the docs and have tried a few settings but keep getting errors, sure i had this working last week before i tore it down ready to deploy for production and now i just cant get it to complete the deployment because of certs, only thing i can think of is i need to run kolla-ansible -i multinode certificates but i thought that was just for self made certs? Also, what are best practices for backend tls certs, self signed or using the internal cert etc?? Is it possible to use letsencrypt at all for backend? Cheers all

[MAGNUM] Fedora Core OS include NVIDIA GPU drivers
by Oliver Weinmann 19 Aug '24

19 Aug '24

Hi all, I'm running OpenStack 2023.2 (Bobcat) deployed with Kolla-Ansible. Currently I'm struggling to get the NVIDIA drivers to work in a FCOS 35 image. I know FCOS 35 is EOL and outdated, but for a K8s 1.21.11 cluster it is the only version that still works with Magnum. So far I managed to get the GPU Passthrough working for two NVIDIA Tesla T4 GPUs. I have attached the GPUs to an Ubuntu instance and ran geekbench without any issues. Then I tried to install the latest NVIDIA drivers in FCOS 35 by running: sudo rpm-ostree install https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$ (rpm -E %fedora).noarch.rpm https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$ (rpm -E %fedora).noarch.rpm systemctl reboot rpm-ostree install --apply-live akmod-nvidia akmods pciutils rpmdevtools xorg-x11-drv-nvidia-cuda It fails on: rpm-ostree install --apply-live akmod-nvidia akmods pciutils rpmdevtools xorg-x11-drv-nvidia-cuda error: Cannot download rpm-build-libs-4.17.0-4.fc35.x86_64.rpm: All mirrors were tried; Last error: Status code: 403 for https://fedoraproject-updates-archive.fedoraproject.org/fedora/35/x86_64/rp… I guess the binaries are no longer hosted? Running the same on FCOS 36 and latest FCOS 40 works fine. Next I have taken new images from the FCOS instances with the NVIDIA driver. openstack server image create --name fedora_coreos_36_nvidia_cuda fedora_coreos_35_latest_no_update --wait This takes ages but anyway I can successfully deploy new instances from the images with my gpu flavor and the GPU is working fine. Again tested with geekbench. But now when adding new K8s worker nodes in a fresh nodegroup on an existing K8s 1.21.11 cluster the nodes are not joining the cluster: openstack coe nodegroup create \ --node-count 1 \ --role worker-gpu \ --flavor gpuflavor \ --image fedora_coreos_36_nvidia_cuda \ $CLUSTER_ID worker-gpu I have tested the latest available images of FCOS36 and they work fine, so something must be wrong with how I created the new image. Is there some magic that needs to be done? I'm also not sure if this is the best way of doing this. Maybe there is already a ready FCOS image with nvidia drivers? I can find lots of outdated information on the internet. Generally I tend to use Vexxhost CAPI from now on, which works great. This is really just a one off attempt to have a working NVIDIA T4 GPU in a K8s 1.21.11 cluster. Best Regards, Oliver

[rabbitmq] Maximum Number of Sessions (8192) Reached
by Eugen Block 14 Aug '24

14 Aug '24

Hi *, I can't seem to find much about rabbitmq and logind, so I wanted to ask the list if anyone has encountered the same and if so, how they dealt with it. We're supporting a Victoria cluster (installed with our own deployment method) mostly controlled by pacemaker. And on the rabbit master node I see this warning constantly: ---snip--- 2024-07-29T14:09:23.552576+02:00 control01 su: pam_unix(su:session): session opened for user rabbitmq by (uid=0) 2024-07-29T14:09:24.450657+02:00 control01 su: pam_unix(su:session): session closed for user rabbitmq 2024-07-29T14:09:24.500356+02:00 control01 su: (to rabbitmq) root on none 2024-07-29T14:09:24.502370+02:00 control01 su: pam_systemd(su:session): Failed to create session: Maximum number of sessions (8192) reached, refusing further sessions. 2024-07-29T14:09:24.502681+02:00 control01 su: pam_unix(su:session): session opened for user rabbitmq by (uid=0) 2024-07-29T14:09:25.565203+02:00 control01 su: pam_unix(su:session): session closed for user rabbitmq 2024-07-29T14:09:25.609613+02:00 control01 su: (to rabbitmq) root on none ---snip--- Looking into loginctl list-sessions, almost all of them belong to rabbitmq and they have a very old timestamp (2023). I'm aware of older systemd versions which can't handle closing sessions correctly [0], but we can't upgrade at this time. Would enabling "linger" fix this (loginctl enable-linger rabbitmq) after a reboot? During the next maintenance window I would reboot control01 and watch how the other control nodes behave wrt rabbit login-sessions. But I'm wondering if somebody already has dealt with this? Thanks for any pointers! Eugen [0] https://www.suse.com/support/kb/doc/?id=000020549

Firewall as a Service - kolla ansible 2023.1
by Thamanna Farhath 06 Aug '24

06 Aug '24

Hello OpenStack Community, I hope this message finds you well. My name is Thamanna , and I am currently working with the OpenStack Kolla-Ansible deployment version 2023.1. I am interested in deploying Firewall as a Service (FWaaS) within our OpenStack environment. However, I have noticed that FWaaS is not available in the Kolla-Ansible 2023.1 version. Could anyone please provide guidance on the following points? 1. Is there an official or recommended way to integrate FWaaS with Kolla-Ansible 2023.1? 2. Are there any specific configurations or additional components required to enable FWaaS? 3. Has anyone in the community successfully deployed FWaaS with this version, and if so, could you share your experience and any potential challenges faced? 4. Are there alternative approaches or tools that you would recommend for deploying FWaaS in an OpenStack environment? Any help or pointers to relevant documentation would be greatly appreciated. Thank you in advance for your assistance!

Live migration fails

Hi, I have couple of compute nodes where the live migration fails with existing vms.
