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

Live migration fails
by Szabo, Istvan (Agoda) 07 Aug '24

07 Aug '24

Hi, I have couple of compute nodes where the live migration fails with existing vms. When I quickly spawn a vm and try live migration it works so I assume shouldn't be a big problem with the compute node. However I have many existing vms where it fails with a servername not found. /var/log/nova/nova-conductor.log:2021-04-21 14:47:12.605 227612 ERROR nova.conductor.tasks.migrate [req-f4067a26-a233-4673-8c07-9a8a290980b0 dce35e6eceea4312bb0baa0510cef363 ca7e35079f4440c78bd9870724b9638b - default default] [instance: 1517a2ac-3b51-4d8d-80b3-89a5614d1ae0] Unable to find record for source node servername on servername: ComputeHostNotFound: Compute host servername could not be found. /var/log/nova/nova-conductor.log:2021-04-21 14:47:12.605 227612 WARNING nova.scheduler.utils [req-f4067a26-a233-4673-8c07-9a8a290980b0 dce35e6eceea4312bb0baa0510cef363 ca7e35079f4440c78bd9870724b9638b - default default] Failed to compute_task_migrate_server: Compute host servername could not be found.: ComputeHostNotFound: Compute host servername could not be found. /var/log/nova/nova-conductor.log:2021-04-21 14:47:12.605 227612 WARNING nova.scheduler.utils [req-f4067a26-a233-4673-8c07-9a8a290980b0 dce35e6eceea4312bb0baa0510cef363 ca7e35079f4440c78bd9870724b9638b - default default] [instance: 1517a2ac-3b51-4d8d-80b3-89a5614d1ae0] Setting instance to ACTIVE state.: ComputeHostNotFound: Compute host servername could not be found. /var/log/nova/nova-conductor.log:2021-04-21 14:47:12.672 227612 ERROR oslo_messaging.rpc.server [req-f4067a26-a233-4673-8c07-9a8a290980b0 dce35e6eceea4312bb0baa0510cef363 ca7e35079f4440c78bd9870724b9638b - default default] Exception during message handling: ComputeHostNotFound: Compute host am-osfecn-4025 Tried with this command: nova live-migration --block-migrate id.

[all] Dynamic Zuul results table in Gerrit 3
by Radosław Piliszek 05 Aug '22

05 Aug '22

Hello Fellow OpenStack and OpenDev Folks! TL;DR click on [3] and enjoy. I am starting this thread to not hijack the discussion happening on [1]. First of all, I would like to thank gibi (Balazs Gibizer) for hacking a way to get the place to render the table in the first place (pun intended). I have been a long-time-now user of [2]. I have improved and customised it for myself but never really got to share back the changes I made. The new Gerrit obviously broke the whole script so it was of no use to share at that particular state. However, inspired by gibi's work, I decided to finally sit down and fix it to work with Gerrit 3 and here it comes: [3]. Works well on Chrome with Tampermonkey. Not tested others. I hope you will enjoy this little helper (I do). I know the script looks super fugly but it generally boils down to a mix of styles of 3 people and Gerrit having funky UI rendering. Finally, I'd also like to thank hrw (Marcin Juszkiewicz) for linking me to the original Michel's script in 2019.

Nova not updating to new size of an extended in-use / attached cinder volume (Ceph RBD) to guest
by Christian Rohmann 28 Jun '22

28 Jun '22

Hello Openstack-Discuss, after some digging I found out that cinder learned to resize attached (in-use) volumes quite a while ago with the introduction of the initial "extend 'in-use' volume" feature: https://review.opendev.org/c/openstack/cinder/+/454287/ The support was then extended to also cover Ceph RBD backed volumes with: https://review.opendev.org/c/openstack/nova/+/613039/ Since this is only about the cinder part, I was wondering if nova would ever find out and would actively rescan the device / volume and quintessentially present an increased new size to the guest. Apparently this is where a certain volume-extended event comes into play: https://review.opendev.org/c/openstack/nova/+/454322/ that is to be emitted by cinder when a volume had been extened. I then went head and tried this with the openstack cli (as Horizon does not seem to support / offer to resize in-use volumes. I run Openstack Train with Ceph RBD as storage. First I ran into an issue with the openstack cli (https://bugs.launchpad.net/cinder/+bug/1871759/comments/2 <https://bugs.launchpad.net/cinder/+bug/1871759/comments/2>) but using cinder extend $volumeid $newsize I was able to resize in-use volumes just fine. The only thing missing was the propagation to the guest. I played around with SCSI rescans, but that did not work, reboots also failed to do anyting in this regards. Stopping and starting the VM did work, but why having the capability to online-resize an attached volume when not being able to resize the guest volume as well? Apparently there seems to be an old and somewhat similar observation / bug with https://bugs.launchpad.net/nova/+bug/1369465 So I was simply wondering if this is expected to be working? Are there any special settings / options I need to set to enable this feature? Thanks and with kind regards Christian

[oslo] Propose to EOL stable/queens, stable/rocky on all the oslo scope
by Herve Beraud 25 Jun '22

25 Jun '22

Hi, On our last meeting of the oslo team we discussed the problem with broken stable branches (rocky and older) in oslo's projects [1]. Indeed, almost all these branches are broken. Előd Illés kindly generated a list of periodic-stable errors on Oslo's stable branches [2]. Given the lack of active maintainers on Oslo and given the current status of the CI in those branches, I propose to make them End Of Life. I will wait until the end of month for anyone who would like to maybe step up as maintainer of those branches and who would at least try to fix CI of them. If no one will volunteer for that, I'll EOLing those branches for all the projects under the oslo umbrella. Let us know your thoughts. Thank you for your attention.

[nova][dev] Revisiting qemu emulation where guest arch != host arch
by Apsey, Christopher 06 Jan '22

06 Jan '22

All, A few years ago I asked a question[1] about why nova, when given a hw_architecture property from glance for an image, would not end up using the correct qemu-system-xx binary when starting the guest process on a compute node if that compute nodes architecture did not match the proposed guest architecture. As an example, if we had all x86 hosts, but wanted to run an emulated ppc guest, we should be able to do that given that at least one compute node had qemu-system-ppc already installed and libvirt was successfully reporting that as a supported architecture to nova. It seemed like a heavy lift at the time, so it was put on the back burner. I am now in a position to fund a contract developer to make this happen, so the question is: would this be a useful blueprint that would potentially be accepted? Most of the time when people want to run an emulated guest they would just nest it inside of an already running guest of the native architecture, but that severely limits observability and the task of managing any more than a handful of instances in this manner quickly becomes a tangled nightmare of networking, etc. I see real benefit in allowing this scenario to run natively so all of the tooling that exists for fleet management 'just works'. This would also be a significant differentiator for OpenStack as a whole. Thoughts?

[stable][requirements][zuul] unpinned setuptools dependency on stable
by Balazs Gibizer 16 Dec '21

16 Dec '21

Hi, The latest setuptools (58.0) removed support for "use_2to3" [1] (deprecated since 46.2). Many OpenStack modules defines decorator==3.4.0 as lower constraints[2]. However, decorator 3.4.0 cannot be installed anymore with the latest setuptool as it depends on "use_2to3". On master, this can be solved easily by bumping the dependency to decorator 4.0.0. On stable/xena we can still solve it the same way with a new RC. But on older stable branches such solution might be against the stable policy as it would require a major bump on our dependencies. This issue is not limited to lower-constraints testing it just hit us there first. A similar break could happen in our upper constraints as well on old stable branches. The root of the problem is that we always use the latest setuptools in our CI testing even on old stable branches. Zuul's ensure-tox task[4] installs tox which installs the virtualenv package which bundles the latest setuptools package. This happens without applying any constraints. Then tox is used to install the project's dependencies under lower or upper constraints with the unconstrained setuptools available. During and after yesterday's nova meeting [3] we discussed possible solutions. Option 1: Bump the major version of the decorator dependency on stable. Pros: * easy to implement Cons: * might against the policy / breaks downstream packagers * needs to be done in each affected project[3] separately * not future proof. After a future setuptools release we can see a similar break with another of our dependencies. @Stable Cores: how do you feel about such bump? Option 2: Pin the setuptools version during tox installation Pros: * single solution for all affected projects * future proof against breaks introduced by future setuptools releases Cons: * complex change as it probably requires to extend the base task in zuul itself Option 3: turn off lower-constraints testing Pros: * easy to implement * some of us want to get rid of lower constraints anyhow Cons: * needs per project changes * not future proof against similar break affecting our upper constraints on old stable branches. Option 4: utilize pyproject.toml[6] to specify build-time requirements Unfortunately, I'm not sure if it is possible to restrict the maximum setuptools version with it As a side note I tried applying [tox]requires in tox.ini to restrict setuptools version[7] but It does not seem to take effect in our case[8]. @Stable Cores: what do you think what could be the way forward? Cheers, gibi [1] https://setuptools.pypa.io/en/latest/history.html#v58-0-2 [2] https://codesearch.openstack.org/?q=decorator%3D%3D3.4.0&i=nope&literal=nop… [3] https://meetings.opendev.org/irclogs/%23openstack-nova/%23openstack-nova.20… [4] https://opendev.org/zuul/zuul-jobs/src/branch/master/roles/ensure-tox/tasks… [5] https://tox.readthedocs.io/en/latest/config.html#conf-requires [6] https://www.python.org/dev/peps/pep-0518/ [7] https://review.opendev.org/c/openstack/placement/+/810293/1/tox.ini [8] https://zuul.opendev.org/t/openstack/build/f78a0300c8734e7c8475309af1d2e1a4…

[puppet] Propose retiring old stable branches(Stein, Rocky and Queens)
by Takashi Kajinami 26 Nov '21

26 Nov '21

Hello, In puppet repos we have plenty of stable branches still open, and the oldest is now stable/queens. However recently we haven't seen many backports proposed to stein, rocky and queens [1], so I'll propose retiring these three old branches now. Please let me know if anybody is interested in keeping any of these three. Note that currently CI jobs are broken in these three branches and it is likely we need to investigate the required additional pinning of dependent packages. If somebody is still interested in maintaining these old branches then these jobs should be fixed.

[all][sphinx] "rST localisation for language "foo" not found" error
by Stephen Finucane 25 Nov '21

25 Nov '21

We've seen issues in some projects, whereby attempting to build translations as part of the 'openstack-tox-docs' zuul job [1] can result in the following warning: Warning, treated as error: ../doc/source/contributor/contributing.rst::rST localisation for language "id" not found. Based on [2], this issue appears to have been introduced by a recent version bump of docutils, which was in turn introduced by the introduction of Sphinx 4.x. We don't have a resolution for this bug yet but we'll update when we do. Hopefully this email will improve the "Google'ability" of this bug.

Adjutant needs contributors (and a PTL) to survive!
by Adrian Turjak 16 Nov '21

16 Nov '21

Hello fellow OpenStackers! I'm moving on to a different opportunity and my new role will not involve OpenStack, and there sadly isn't anyone at Catalystcloud who will be able to take over project responsibilities for Adjutant any time soon (not that I've been very onto it lately). As such Adjutant needs people to take over, and lead it going forward. I believe the codebase is in a reasonably good position for others to pick up, and I plan to go through and document a few more of my ideas for where it should go in storyboard so some of those plans exist somewhere should people want to pick up from where I left off before going fairly silent upstream. Plus if people want/need to they can reach out to me or add me to code review and chances are I'll comment/review because I do care about the project. Or I may contract some time to it. There are a few clouds running Adjutant, and people who have previously expressed interest in using it, so if you still are, the project isn't in a bad place at all. The code is stable, and the last few major refactors have cleaned up much of my biggest pain points with it. Best of luck! - adriant

[kuryr] Using kuryr-kubernetes CNI without neutron agent(s)?
by Jason Anderson 08 Nov '21

08 Nov '21

Hello all, I’m interested in letting Neutron provide the network configuration frontend for networks realized on k8s kubelets. I have been reading a lot about kuryr-kubernetes and it looks like it fits the bill, but some of the older architecture diagrams I’ve seen indicate that OVS and the neutron-openvswitch-agent (or similar) must also run on the kubelet node. Is this still accurate? I am hoping to avoid this because my understanding is that running the OVS agent means giving the kubelet node access to RabbitMQ and potentially storing admin keystone creds on the node as well. Can kuryr-kubernetes work without such an agent co-located? Thanks!

[docs] Double headings on every page
by Peter Matulis 05 Nov '21

05 Nov '21

Hi, I'm hitting an oddity in one of my projects where the titles of all pages show up twice. Example: https://docs.openstack.org/project-deploy-guide/charm-deployment-guide/wall… Source file is here: https://opendev.org/openstack/charm-deployment-guide/src/branch/master/depl… Does anyone see what can be causing this? It appears to happen only for the current stable release ('wallaby') and 'latest'. Thanks, Peter

Hi, I have installed barbican and using it with openstack magnum. When I am using the default kek describe in document below, works fine and magnum cluster creation goes successful. https://docs.openstack.org/barbican/latest/install/barbican-backend.html But when I generate a new kek with below command. python3 -c "from cryptography.fernet import Fernet ; key = Fernet.generate_key(); print(key)" and put it in barbican.conf, the magnum cluster failed to create and I see below logs in barbican. 2021-10-29 12:53:28.932 568554 INFO barbican.plugin.crypto.simple_crypto [req-aaac01e9-82af-421b-b85a-ff998d904972 ad702ac807f44c73a32a9b7a795b693c d782069f335041138f0cb141fde9933f -

[ptl][release][stable][EM] Extended Maintenance - Ussuri
by Előd Illés 04 Nov '21

04 Nov '21

Hi, As Xena was released last week and we are in a less busy period, now it is a good time to call your attention to the following: In a month Ussuri is planned to transition to Extended Maintenance phase [1] (planned date: 2021-11-12). I have generated the list of the current *open* and *unreleased* changes in stable/ussuri for the follows-policy tagged repositories [2] (where there are such patches). These lists could help the teams who are planning to do a *final* release on Ussuri before moving stable/ussuri branches to Extended Maintenance. Feel free to edit and extend these lists to track your progress! * At the transition date the Release Team will tag the *latest* Ussuri releases of repositories with *ussuri-em* tag. * After the transition stable/ussuri will be still open for bug fixes, but there won't be official releases anymore. *NOTE*: teams, please focus on wrapping up your libraries first if there is any concern about the changes, in order to avoid broken (final!) releases! Thanks, Előd [1] https://releases.openstack.org/ [2] https://etherpad.opendev.org/p/ussuri-final-release-before-em

[horizon][dev]Handle multiple login sessions from same user in Horizon
by Luz de Avila, Arthur 02 Nov '21

02 Nov '21

Hi everyone, In order to improve the system my colleagues and I would like to bring up a new feature to Horizon. We found out that an user is able to login in Horizon with the same credentials in multiple devices or/and browsers. This may be not very secure as the user can login in many different devices or/and browsers with the same credential. Thinking on that, we would like bring up more control to the admin of the system in a way that the admin can enable or disable the multiple login sessions according to the needs of the system. For a better follow up of this propose, a blueprint has been opened with more details about the idea and concepts of this and we would like the onion of the community whether this feature make sense to implement or not. The blueprint opened on launchpad: https://blueprints.launchpad.net/horizon/+spec/handle-multiple-login-sessio… Kind regards, Arthur Avila
