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)

[nova][dev] Revisiting qemu emulation where guest arch != host arch
by Apsey, Christopher 05 Jan '22

05 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?

Help with eventlet 0.26.1 and dnspython >= 2
by Thomas Goirand 04 Oct '21

04 Oct '21

Hi, As you may know, eventlet is incompatible with dnspython >= 2.0.0.0rc1. See [1] for the details. However, Debian unstable has 2.0.0. Would there be some good soul willing to help me fix this situation? I would need a patch to fix this, but I'm really not sure how to start. Cheers, Thomas Goirand (zigo)

[simplification] Making ask.openstack.org read-only
by Thierry Carrez 27 May '21

27 May '21

Hi everyone, This has been discussed several times on this mailing list in the past, but we never got to actually pull the plug. Ask.openstack.org was launched in 2013. The reason for hosting our own setup was to be able to support multiple languages, while StackOverflow rejected our proposal to have our own openstack-branded StackExchange site. The Chinese ask.o.o side never really took off. The English side also never really worked perfectly (like email alerts are hopelessly broken), but we figured it would get better with time if a big community formed around it. Fast-forward to 2020 and the instance is lacking volunteers to help run it, while the code (and our customization of it) has become more complicated to maintain. It regularly fails one way or another, and questions there often go unanswered, making us look bad. Of the top 30 users, most have abandoned the platform since 2017, leaving only Bernd Bausch actively engaging and helping moderate questions lately. We have called for volunteers several times, but the offers for help never really materialized. At the same time, people are asking OpenStack questions on StackOverflow, and sometimes getting answers there[1]. The fragmentation of the "questions" space is not helping users getting good answers. I think it's time to pull the plug, make ask.openstack.org read-only (so that links to old answers are not lost) and redirect users to the mailing-list and the "OpenStack" tag on StackOverflow. I picked StackOverflow since it seems to have the most openstack questions (2,574 on SO, 76 on SuperUser and 430 on ServerFault). We discussed that option several times, but I now proposed a change to actually make it happen: https://review.opendev.org/#/c/746497/ It's always a difficult decision to make to kill a resource, but I feel like in this case, consolidation and simplification would help. Thoughts, comments? [1] https://stackoverflow.com/questions/tagged/openstack -- Thierry

[ironic] Announcing deprecation of the iSCSI deploy interface
by Dmitry Tantsur 04 May '21

04 May '21

Hi all, Following up to the previous mailing list [1] and virtual meetup [2] discussions, I would like to announce the plans to deprecate the 'iscsi' deploy interface. This is the updated plan discussed on the virtual meetup: 1) In the Victoria cycle (i.e. right now): - Fill in the detected feature gaps [3]. - Switch off the iscsi deploy interface by default. - Change [agent]image_dowload_source to HTTP by default. - Give the direct deploy a higher priority, so that it's used by default unless disabled. - Mark it as deprecated in the code (causing warnings when enabled). - Release a major version of ironic to highlight the defaults changes. 2) In the W cycle: - Keep the iscsi deploy deprecated. - Listen to operators' feedback. 3) In the X cycle - Remove the iscsi deploy completely from ironic and IPA. - Remove support code from ironic-lib with a major version bump. Please let us know if you have any questions or concerns.

[largescale-sig] OpenStack DB Archiver
by Arnaud Morin 10 Feb '21

10 Feb '21

Hello large-scalers! TLDR: we opensource a tool to help reducing size of databases. See https://github.com/ovh/osarchiver/ Few months ago, we released a tool, name osarchiver, which we are using on our production environment (at OVH) to help reduce the size of our tables in mariadb (or mysql) In fact, some tables are well know to grow very quickly. We use it, for example, to clean the OpenStack mistral database from old tasks, actions and executions which are older than a year. Another use case could be to archive some data in another table (e.g. with _archived as suffix) if they are 6 months old, and delete this data after 1 year. The source code of this tool is available here: https://github.com/ovh/osarchiver/ We were wondering if some other users would be interested in using the tool, and maybe move it under the opendev governance? Feel free to contact us and/or answer this thread. Cheers, -- Arnaud, Pierre-Samuel and OVH team

[qa][tempest] Update language in tempest code base
by Arx Cruz 05 Jan '21

05 Jan '21

Hello, I would like to start a discussion regarding the topic. At this moment in time we have an opportunity to be a more open and inclusive project by eliminating outdated naming conventions from tempest codebase, such as blacklist, whitelist. We should take the opportunity and do our best to replace outdated terms with their more inclusive alternatives. As you can see in [1] the TripleO project is already working on this initiative, and I would like to work on this as well on the tempest side. Any thoughts? Shall I start with a sepc, adding deprecation warnings?

Re: [placement] Train upgrade warning
by Seth Tunstall 21 Dec '20

21 Dec '20

Hello, As another person has mentioned (Chanu Romain), I am attempting an upgrade from Queens to Train. I have successfully upgraded Keystone and Glance, but while trying to separate Placement's databases out from Nova, I run into the the same issue with placement-status upgrade check: # placement-status upgrade check +-----------------------------------------------------------------+ | Upgrade Check Results | +-----------------------------------------------------------------+ | Check: Missing Root Provider IDs | | Result: Success | | Details: None | +-----------------------------------------------------------------+ | Check: Incomplete Consumers | | Result: Warning | | Details: There are -3511 incomplete consumers table records for | | existing allocations. Run the "placement-manage db | | online_data_migrations" command. | +-----------------------------------------------------------------+ Likewise, running placement-manage db online_data_migrations does nothing. I am running this placement migration on a dev cluster which has had the databases from a Prod cluster restored to it. This has worked well for me previously as a way to run through upgrades without touching the live system. Thanks very much, Seth

[ptl][release][stable][EM] Extended Maintenance - Stein
by Előd Illés 26 Nov '20

26 Nov '20

Hi, As Victoria was released yesterday and we are in a less busy period, it is a good opportunity to call your attention to the following: In less than a month Stein is planned to enter into Extended Maintenance phase [1] (planned date: 2020-11-11). I have generated the list of *open* and *unreleased* changes in *stable/stein* for the follows-policy tagged repositories [2]. These lists could help the teams, who are planning to do a *final* release on Stein before moving stable/stein 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* (Stein) releases of repositories with *stein-em* tag. * After the transition stable/stein will be still open for bugfixes, but there won't be any official releases. NOTE: teams, please focus on wrapping up your libraries first if there is any concern about the changes, in order to avoid broken releases! Thanks, Előd [1] https://releases.openstack.org [2] https://etherpad.openstack.org/p/stein-final-release-before-em

[SDK][OSC] Meeting Times
by Kendall Nelson 16 Nov '20

16 Nov '20

Hello! In the PTG session today we talked about doing some sort of regular meetings to kind of jump start things after the more recent lack of activity. We discussed beginning with more frequent meetings (a couple across the next few weeks) and then shifting to a more relaxed monthly cadence. I propose 15:00 UTC on the third thursday of each month as our monthly meeting time? If people agree, I will propose a patch :) As for the more frequent ones to keep the momentum from discussion from this week/last week. We could use that time (15 UTC) and date (Thursdays) and maybe just do them on Nov 12 and 19th to keep us moving? That gives us next week to catch up/ take a breath from the last two weeks, but not waiting till after the US Thanksgiving holiday. Let me know what you think! -Kendall Nelson (diablo_rojo)

CloudKitty deployment on Train and/or Ussuri
by Thode Jocelyn 15 Nov '20

15 Nov '20

Hi, I was looking at the possibilities to have Rating-as-A-Service in our Openstack (currently train but planning to move to Ussuri) and I stumbled upon CloudKitty. I'm currently facing multiple issues with cloudkitty itself and with openstack-ansible. (We are using a containerized deployment with LXC) * I noticed that openstack-ansible has no playbook yet to install a service like CloudKitty even though starting from Ussuri it was added in the ansible-role-requirements.yml. I have created a small patch to be able to install CloudKitty via openstack-ansible and if this is of interest I could potentially submit a PR with this. * The os_cloudkitty role seems to kinda work and only with a relatively old version of CloudKitty. For example, here : https://opendev.org/openstack/openstack-ansible-os_cloudkitty/src/branch/st… since CloudKitty v8.0.0 the section should be named "[fetcher_keystone]", but I found no information as to which CloudKitty version should be used with this role. Does someone have any recommendation as to which version should be used and if there is any interest in improving the role to support more recent versions of CloudKitty? * Even when tweaking the configuration and installing v7.0.0 of Cloudkitty it only fixes cloudkitty-processor, I was never able to make cloudkitty-api work I always get an error like "Fatal Python error: Py_Initialize: Unable to get the locale encoding ModuleNotFoundError: No module named 'encodings'". Any input on this would be greatly appreciated. Cheers Jocelyn

[neutron][stable]Proposing Rodolfo Alonso Hernandez as a stable branches core reviewer
by Slawek Kaplonski 06 Nov '20

06 Nov '20

Hi, I would like to propose Rodolfo Alonso Hernandez (ralonsoh) to be new member of the Neutron stable core team. Rodolfo works in Neutron since very long time. He is core reviewer in master branch already. During last few cycles he also proved his ability to help with stable branches. He is proposing many backports from master to our stable branches as well as doing reviews of other backports. He has knowledge about stable branches policies. I think that he will be great addition to our (not too big) stable core team. I will open this nomination open for a week to get feedback about it. -- Slawek Kaplonski Principal Software Engineer Red Hat

Editing libvirt xml file
by vladimir franciz blando 04 Nov '20

04 Nov '20

Hi, I edited the libvirt xml (virsh edit...) file of a running Windows server instance because I changed the video model type from cirrus to vmvga so it can support a higher resolution on a console (cirrus supports up to 1280 only). After editing, i "soft-rebooted" the instance and the new configuration sticks. That's awesome. But when you do a "hard-reboot" it will revert back to the original config. I also tried to do a "shut-down" then "start" again, but it still reads the original config. Not sure where it is reading the config from... Regards Vlad

[placement][nova][cinder][neutron][blazar] Placement governance switch(back)
by Stephen Finucane 03 Nov '20

03 Nov '20

Placement has been a separate project with its own governance since Stein [1]. Since then, the main drivers behind the separation have moved onto pastures new and with Tetsuro sadly declaring his non- candidacy for the PTL position for Wallaby [2], we're left in the unenviable position of potentially not having a PTL for the Wallaby cycle. As such, it's probably time to discuss the future of Placement governance. Assuming no one steps forward for the Placement PTL role, it would appear to me that we have two options. Either we look at transitioning Placement to a PTL-less project, or we move it back under nova governance. To be honest, given how important placement is to nova and other projects now, I'm uncomfortable with the idea of not having a point person who is ultimately responsible for things like cutting a release (yes, delegation is encouraged but someone needs to herd the cats). At the same time, I do realize that placement is used by more that nova now so nova cores and what's left of the separate placement core team shouldn't be the only ones making this decision. So, assuming the worst happens and placement is left without a PTL for Victoria, what do we want to do? Stephen PS: Apologies if I missed other projects with an interest in placement.

[tripleo] please avoid creating ansible playbooks that call modules for trivial tasks
by Bogdan Dobrelya 02 Nov '20

02 Nov '20

Hi, In today TripleO client development we invoke ansible playbooks instead of Mistral workflows. I believe this may only be justified for non-trivial things. Otherwise please just import python modules into the client command actions without introducing additional moving parts in the form of ansible modules (that import the same python modules as well). Ansible brings declarative DSL that sometimes can better and simpler and faster describes things to do and shape inputs data, than if the same would be done in python, in the client. What should be the trivial thing and non-trivial then? Well, I think that example [0] illustrates such a trivial thing. A new playbook [1] would only install a few packages then "returns" back into python and calls a new ansible module [2]. And that new module only wraps [3] the same code being removed from the client: from tripleo_common.image import build ... manager = build.ImageBuildManager(<args>) I see no point of adding a new playbook and a new module for that trivial example. Those 4 packages could (and should) be as well installed from the client caller code without any ansible involved in the middle IMO.

[tripleo] stable/victoria for tripleo repos
by Marios Andreou 02 Nov '20

02 Nov '20

Hello all, I got some pings about tripleo stable/victoria so here is an update. The tripleo-ci team is busy preparing and we are almost ready. Basically we've blocked branching until we have adequate CI coverage. This means check & gate jobs but also promotion jobs so that check & gate aren't running with stale content. tl;dr We are aiming to branch victoria tripleoclient & common today and everything else next week - with more details below but please note: PLEASE AVOID MERGING to the stable/victoria tripleoclient/common that will appear after [4] until we are confident that our ci coverage is working well. Status: Most of our 'core' (standalone/scenarios/undercloud etc) check/gate jobs match on branch like [1] so we expect those to run OK once there is a stable/victoria available. There is ongoing work for branchful, upgrade, 3rd party and ovb jobs but we will not block branching on those. The victoria integration pipeline [2] (which produces current-tripleo) is in good shape. It was blocked on a nit in the component pipeline but it is resolved with [3]. Once we have a victoria promotion then we should be all clear to branch stable/victoria. Actions: A). today: make stable/victoria for python-tripleoclient & tripleo-common. The change at [4] will do this once merged. We will use this to see our check/gate jobs run against victoria & fix issues. B). next week: once we are happy with A). AND we've had a promotion, we release and make stable/victoria for everything else. Hopefully B). will happen end of next week but that depends on how well the above goes (plus inevitable delays cos PTG), I'll repeat this cos it's important: PLEASE AVOID MERGING to stable/victoria tripleoclient/common for now until we are confident that our jobs are doing the right thing! As always grateful for a sanity check or any thoughts about any of the above - I'm pretty new to this (weshay has been a great help so far thank you weshay++), thanks, marios [1] https://opendev.org/openstack/tripleo-ci/src/commit/d5514028452f9d427949f5a… [2] https://review.rdoproject.org/zuul/builds?pipeline=openstack-periodic-integ… [3] https://review.rdoproject.org/r/#/c/30654/ [4] https://review.opendev.org/#/c/759449/

Python 3.9 is here in Debian Sid
by Thomas Goirand 02 Nov '20

02 Nov '20

Hi there! Matthias Klose decided that uploading Python 3.9 on the 14th of this month (yes, the same day of the OpenStack release) would be fun. I am now really having fun ... fixing bugs! :) What's not so funny for me, is that some key packages like Greenlet or lxml aren't built yet for Python 3.9, even though they should. As a consequence, I just need to wait to be able to upload to Unstable. So this will delay my usual announcement for the release GA in Debian (even though the unofficial Victoria repo for Buster is ready and I could spawn VMs on Buster + Victoria). Anyways, all of this will settle slowly. Though Python 3.9 is here to stay, and to soon reach Ubuntu as well (it's planned for the next release). It'd be nice if projects were starting to investigate gating on Python 3.9 as early as possible. As much as I can tell, there's not so many issues to fix. The first one I fixed is here: https://review.opendev.org/758237 but I don't expect much more, and hopefully, I'll be able to propose more patch as I find the issues. Must we wait until Python 3.9 reaches Ubuntu to enable gating in the OpenStack projects? FYI, I do expect Victoria to run over Python 3.9 in Bullseye. Please don't reply with the usual "Victoria doesn't support it", because that's irrelevant. I'm fine with backporting patches, as long as they also exist in Wallaby. Cheers, Thomas Goirand (zigo)

[magnum] hyperkube deprecation situation
by Ionut Biru 02 Nov '20

02 Nov '20

Hi guys, I was hoping that in Victoria there will be a decision regarding this topic. Currently, if I use vanilla magnum, I'm stuck on 1.18.6 being the latest version, even so 1.18.10 was released. We are kinda stuck on a version that maybe in the near future is pruned to security issues. How do other operators are using magnum (vanilla) and keeping their kubernetes up to date? Are operators using a forked version of https://review.opendev.org/#/c/752254/ ? -- Ionut Biru - https://fleio.com
