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) 06 Aug '24

06 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 04 Aug '22

04 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. [1] http://lists.openstack.org/pipermail/openstack-discuss/2020-November/019051… [2] https://opendev.org/x/coats/src/commit/444c95738677593dcfed0cfd9667d4c4f0d5… [3] https://gist.github.com/yoctozepto/7ea1271c299d143388b7c1b1802ee75e Kind regards, -yoctozepto

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 24 Jun '22

24 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.

[TripleO] Core team cleanup
by James Slagle 30 Mar '22

30 Mar '22

Hello, I took a look at our core team, "tripleo-core" in gerrit. We have a few individuals who I feel have moved on from TripleO in their focus. I looked at the reviews from stackalytics.io for the last 180 days[1]. These individuals have less than 6 reviews, which is about 1 review a month: Bob Fournier Dan Sneddon Dmitry Tantsur Jiří Stránský Juan Antonio Osorio Robles Marius Cornea These individuals have publicly expressed that they are moving on from TripleO: Michele Baldessari wes hayutin I'd like to propose we remove these folks from our core team, while thanking them for their contributions. I'll also note that I'd still value +1/-1 from these folks with a lot of significance, and encourage them to review their areas of expertise! If anyone on the list plans to start reviewing in TripleO again, then I also think we can postpone the removal for the time being and re-evaluate later. Please let me know if that's the case. Please reply and let me know any agreements or concerns with this change. Thank you! [1] https://www.stackalytics.io/report/contribution?module=tripleo-group&projec… -- -- James Slagle --

[infra] gerrit is:mergeable predicate
by Brian Rosmaita 15 Mar '22

15 Mar '22

Hello Infra team, In Gerrit 3.4, the is:mergeable predicate is disabled by default [0]. It was kind of handy to be able to screen out patches that are in merge conflict when looking for reviews. Is there an alternative way of doing this, or would you be averse to restoring the previous behavior? (I promise not to complain about gerrit performance.) cheers, brian [0] https://www.gerritcodereview.com/3.4.html#ismergeable-predicate-is-disabled…

[ops][nova] How to update from N to N+3 (and manage nova services that don't start because they find too old compute nodes...)
by Massimo Sgaravatto 28 Feb '22

28 Feb '22

Dear all When we upgraded our Cloud from Rocky to Train we followed the following procedure: 1) Shutdown of all services on the controller and compute nodes 2) Update from Rocky to Stein of controller (just to do the dbsyncs) 3) Update from Stein to Train of controller 4) Update from Rocky to Train of compute nodes We are trying to do the same to update from Train to Xena, but now there is a problem because nova services on the controller node refuse to start since they find too old compute nodes (this is indeed a new feature, properly documented in the release notes). As a workaround we had to manually modify the "version" field of the compute nodes in the nova.services table. Is it ok, or is there a cleaner way to manage the issue ? Thanks, Massimo

[all][tc] Relmgt team position on release cadence
by Thierry Carrez 14 Feb '22

14 Feb '22

Hi everyone, The (long) document below reflects the current position of the release management team on a popular question: should the OpenStack release cadence be changed? Please note that we only address the release management / stable branch management facet of the problem. There are other dimensions to take into account (governance, feature deprecation, supported distros...) to get a complete view of the debate. Introduction ------------ The subject of how often OpenStack should be released has been regularly debated in the OpenStack community. OpenStack started with a 3-month release cycle, then switched to 6-month release cycle starting with Diablo. It is often thought of a release management decision, but it is actually a much larger topic: a release cadence is a trade-off between pressure to release more often and pressure to release less often, coming in from a lot of different stakeholders. In OpenStack, it is ultimately a Technical Committee decision. But that decision is informed by the position of a number of stakeholders. This document gives historical context and describes the current release management team position. The current trade-off --------------------- The main pressure to release more often is to make features available to users faster. Developers get a faster feedback loop, hardware vendors ensure software is compatible with their latest products, and users get exciting new features. "Release early, release often" is a best practice in our industry -- we should generally aim at releasing as often as possible. But that is counterbalanced by pressure to release less often. From a development perspective, each release cycle comes with some process overhead. On the integrators side, a new release means packaging and validation work. On the users side, it means pressure to upgrade. To justify that cost, there needs to be enough user-visible benefit (like new features) in a given release. For the last 10 years for OpenStack, that balance has been around six months. Six months let us accumulate enough new development that it was worth upgrading to / integrating the new version, while giving enough time to actually do the work. It also aligned well with Foundation events cadence, allowing to synchronize in-person developer meetings date with start of cycles. What changed ------------ The major recent change affecting this trade-off is that the pace of new development in OpenStack slowed down. The rhythm of changes was divided by 3 between 2015 and 2021, reflecting that OpenStack is now a mature and stable solution, where accessing the latest features is no longer a major driver. That reduces some of the pressure for releasing more often. At the same time, we have more users every day, with larger and larger deployments, and keeping those clusters constantly up to date is an operational challenge. That increases the pressure to release less often. In essence, OpenStack is becoming much more like a LTS distribution than a web browser -- something users like moving slow. Over the past years, project teams also increasingly decoupled individual components from the "coordinated release". More and more components opted for an independent or intermediary-released model, where they can put out releases in the middle of a cycle, making new features available to their users. This increasingly opens up the possibility of a longer "coordinated release" which would still allow development teams to follow "release early, release often" best practices. All that recent evolution means it is (again) time to reconsider if the 6-month cadence is what serves our community best, and in particular if a longer release cadence would not suit us better. The release management team position on the debate -------------------------------------------------- While releasing less often would definitely reduce the load on the release management team, most of the team work being automated, we do not think it should be a major factor in motivating the decision. We should not adjust the cadence too often though, as there is a one-time cost in switching our processes. In terms of impact, we expect that a switch to a longer cycle will encourage more project teams to adopt a "with-intermediary" release model (rather than the traditional "with-rc" single release per cycle), which may lead to abandoning the latter, hence simplifying our processes. Longer cycles might also discourage people to commit to PTL or release liaison work. We'd probably need to manage expectations there, and encourage more frequent switches (or create alternate models). If the decision is made to switch to a longer cycle, the release management team recommends to switch to one year directly. That would avoid changing it again anytime soon, and synchronizing on a calendar year is much simpler to follow and communicate. We also recommend announcing the change well in advance. We currently have an opportunity of making the switch when we reach the end of the release naming alphabet, which would also greatly simplify the communications around the change. Finally, it is worth mentioning the impact on the stable branch work. Releasing less often would likely impact the number of stable branches that we keep on maintaining, so that we do not go too much in the past (and hit unmaintained distributions or long-gone dependencies). We currently maintain releases for 18 months before they switch to extended maintenance, which results in between 3 and 4 releases being maintained at the same time. We'd recommend switching to maintaining one-year releases for 24 months, which would result in between 2 and 3 releases being maintained at the same time. Such a change would lead to longer maintenance for our users while reducing backporting work for our developers. -- Thierry Carrez (ttx) On behalf of the OpenStack Release Management team

[puppet][tc] Propose changing the release model to cycle-with-rc
by Takashi Kajinami 14 Feb '22

14 Feb '22

Hello, I already discussed this with a few cores last year but I'm raising this topic in ML to make an official decision. Currently Puppet OpenStack is following cycle-with-intermediary and creates a release every milestone. However our code is tightly related to the actual service implementations and having only puppet releases is not very useful. Considering the above point, and effort required to cut off releases per milestone, I'll propose changing our release model to cycle-with-rc , and creating a single release. Because we already created milestone releases for Yoga, I'm thinking of applying the change from next cycle(Z). Please let me know if you have any concerns. Thank you, Takashi

[Skyline] Project mascot to review
by James Cole 09 Feb '22

09 Feb '22

Greetings everyone, I’m James, a designer with the OpenInfra Foundation. We have a been working on a new project mascot for Skyline and wanted to share a couple of options with you. The reference we were provided alluded to a nine-color-deer, so we created a deer illustration in the style of the other project mascots. The two options are essentially the same, but one is white with spots and the other is yellow with spots. Let me know if you like one or the other—or if we’re totally off on the theme—and we will add the text to the logo and finalize the assets. There is a PDF attached to this message or you can view the document by visiting this link <https://www.dropbox.com/s/d2ikaphzhml7tqb/20220120%20Mascots%20Project.pdf?…>. Thank you! -James

[kolla] [horizon] Custom logos (WAS: [Openstack-operators] Horizon Custom Logos (Queens, 13.0.1))
by Gregory Orange 09 Feb '22

09 Feb '22

We have been using Ubuntu VMs for the control plane until now, so it was a simple matter of inserting our logo-splash.svg and logo.svg into /var/lib/openstack-dashboard/static/dashboard/img/ and then restarting services. Now we're switching to Kolla, and the relevant path isn't mounted as is the case with the likes of /etc/kolla/horizon and /var/log/kolla.

[cinder] new driver freeze & exceptions
by Brian Rosmaita 03 Feb '22

03 Feb '22

Hello Argonauts, The new driver merge deadline passed at 20:00 UTC today. I'm extending the new driver merge deadline to Friday 28 January at 20:00 UTC for two drivers: 1. Lightbits: It has both a cinder and os-brick patch, and I want the team to have more time to look at the os-brick patch. I think the driver patch is close to ready; the developers have been quick to respond to comments and make revisions. Also, the third-party CI is functioning and responding on patches. cinder: https://review.opendev.org/c/openstack/cinder/+/821602 os-brick: https://review.opendev.org/c/openstack/os-brick/+/821603 2. NEC Storage V Series: the driver patch has one +2 and the third party CI is functioning and responding on patches; I don't see any reason to make this one wait for the Z release. https://review.opendev.org/c/openstack/cinder/+/815614 Cinder core reviewers: please continue to review the above patches. With respect to the other proposed drivers: - Pure Storage NVMe-RoCE: vendor decided to hold it for Z - Dell EMC PowerStore NFS driver: vendor decided to hold it for Z - HPE XP Storage FC & iSCSI: the code is very straightforward, but the CI is not ready yet, so this will have to wait for Z - YADRO Tatlin.UNIFIED driver: initial patch arrived yesterday (and has a -1 from Zuul); the CI appears to be running, but the cinder team needs to move on to reviewing os-brick and Yoga feature patches, so this will have to wait for Z also cheers, brian

There are a few patch in flight to try address this issue: https://review.rdoproject.org/r/c/rdo-infra/ansible-role-dlrn/+/38673 - Use opstools packages from trunk.rdoproject.org in cs8 https://review.opendev.org/c/openstack/tripleo-quickstart/+/827111/ - Adds temporary rdoproject repo for collectd/opstools Centos-8 Please hold rechecks until we manage to merge the fixes. Thank you!

[all][infra][qa][tripleo][openstack-ansible][rally][aodh][cinder][kolla][chef][sahara] CentOS 8 EOL and removal from CI label/image lists
by Clark Boylan 01 Feb '22

01 Feb '22

As noted last month the OpenDev [0] team intends on removing CentOS 8 images from our CI system now that the release has gone EOL. A number of you have already shifted over to CentOS 8 Stream in CI (thank you!), but there is still quite a bit remaining based on codesearch and some manual digging. The OpenDev team has begun the process of removing some of the supporting infrastructure and testing as well [1]. This list is probably not comprehensive but is a start. These projects will need to look at removing their CentOS 8 CI jobs (optionally replacing them with CentOS 8 Stream jobs): * devstack (victoria and older branches) * tripleo-validations * tripleo-upgrade * openstack-ansible * rally * aodh * cinderlib * kolla-ansible * openstack-chef * sahara * tenks * validations-common * validations-lib One thing to keep in mind is that stable branches may also be affected. We'd like to do this cleanup as gracefully as possible, but reality is that some projects are unlikely to completely remove their use of CentOS 8. I think that we can give it until the end of January before we force merge updates to remove the nodeset and label from our configs. At that point any Zuul configuration still using CentOS 8 will enter an error state and correcting it will be necessary to make updates to those Zuul configs.

[requirements] The version of zeroconf in upper constraints no longer supports python3.6
by William Szumski 01 Feb '22

01 Feb '22

The zeroconf package seems to have dropped support for python3.6 since 0.38.0, see: https://github.com/jstasiak/python-zeroconf#0380. We currently have 0.38.1 in upper-constraints. My understanding was that the yoga release would still support python3.6. This is important for RHEL8 based distributions that only ship python3.6. Do we need to constrain zeroconf to a version <=0.37.0?

[magnum] dropping mesos code
by Mohammed Naser 01 Feb '22

01 Feb '22

Hi there, Does it make sense for us to drop the Mesos driver code from the code base? I don't know of anyone that actually uses it and I believe it's likely not been tested for years. Mohammed -- Mohammed Naser VEXXHOST, Inc.

[nova][placement] Openstack only building one VM per machine in cluster, then runs out of resources
by Eugen Block 01 Feb '22

01 Feb '22

Hi all, I would like to follow up on a discussion from last year [1] since the issue is still present. In a fresh Victoria deployment we faced the same issue and my colleague tracked it down to a reoccuring issue within MariaDB [2]. Quoting from his response to a different thread [3]: ---snip--- MariaDB is version 10.6.5. When running placement API in debug mode, its log reveals a message like "Over capacity for VCPU on resource provider . Needed: 1, Used: 4118, Capacity: 768.0" but checking the entries in the placement db / allocations table shows that "4118" is the sum of all resources for the resource provided, not only for the CPU class. The problem results from errors in the DBMS handling the "outer join" with a subquery while retrieving the currently allocated resources. ---snip--- We found a workaround for this environment, but I wanted to bring some more attention to this, hoping that this will be fixed in MariaDB.

[ironic] Deprecate/Remove PowerPC prep partition support?
by Julia Kreger 31 Jan '22

31 Jan '22

Greetings folks, I've been curious if anyone sees a reason to keep PowerPC PReP partition support in Ironic? A few things to consider: * This is/was to support partition images. * We generally shy away from partition images at this point. We recommend whole disk images. * PowerPC.... And I don't think many (any?) operators will be doing power deployments of Z* and beyond OpenStack once it is released. * This is not tested in CI, because Power hardware... Thoughts? Feelings? Concerns? -Julia

[job] What is the best list for posting an OpenStack job opening?
by Chris DiLorenzo 31 Jan '22

31 Jan '22

Hello, My company has an open position for an OpenStack engineer. We haven't gotten a lot of traction or the candidates we do get lack the OpenStack experience we're looking for. Is it appropriate to post here? Thanks Chris
