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

Hi, I am currently trying to deploy openstack wallaby using tripleo arch. I created the network jinja templates, ran the following commands also: #openstack overcloud network provision --stack overcloud --output networks-deployed-environment.yaml custom_network_data.yaml # openstack overcloud network vip provision --stack overcloud --output vip-deployed-environment.yaml custom_vip_data.yaml # openstack overcloud node provision --stack overcloud --overcloud-ssh-key /home/stack/sshkey/id_rsa overcloud-baremetal-deploy.yaml and used the environment files in the openstack overcloud deploy command: (undercloud) [stack@hkg2director ~]$ cat deploy.sh #!/bin/bash THT=/usr/share/openstack-tripleo-heat-templates/ CNF=/home/stack/ openstack overcloud deploy --templates $THT \ -r $CNF/templates/roles_data.yaml \ -n $CNF/workplace/custom_network_data.yaml \ -e ~/containers-prepare-parameter.yaml \ -e $CNF/templates/node-info.yaml \ -e $CNF/templates/scheduler-hints.yaml \ -e $CNF/workplace/networks-deployed-environment.yaml \ -e $CNF/workplace/vip-deployed-environment.yaml \ -e $CNF/workplace/overcloud-baremetal-deployed.yaml \ -e $CNF/workplace/custom-net-bond-with-vlans.yaml Now when i run the ./deploy.sh script i encounter an error stating: ERROR openstack [-] Resource OS::TripleO::Network::Ports::ControlPlaneVipPort maps to type OS::Neutron::Port and the Neutron service is not available when using ephemeral Heat.

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.

[puppet] Proposing core team clean up
by Takashi Kajinami 23 Aug '23

23 Aug '23

Hello, I went through the current core reviewers and found out that the current list includes some people no longer working in the OpenStack community. I'd like to propose removing the following persons from the core reviewer team as we haven't seen these people making any activity in the community recently. * Pradeep Kilambi - puppet-aodh, puppet-ceilometer, puppet-gnocchi, puppet-panko * Richard Megginson - puppet-keystone * Denis Egorenko - puppet-murano * Serg Melikyan - puppet-murano * Sergey Kolekonov - puppet-neutron * David Moreau Simard - puppet-openstack-integration * Yu xingchao - all modules Also, I confirmed that Wes Hayutin is no longer working for OpenStack and he agreed to retire from the core reviewer position. Thus I'll remove him as well. I'll be open for any feedback for one week to hear any thoughts/feedback about this removal. I'd like to take this moment to thank all people for their past work. We always welcome them back if they resume their work in this project. Thank you, Takashi KAJINAMI

[designate] How to avoid NXDOMAIN or stale data during cold start of a (new) machine
by Christian Rohmann 23 Nov '22

23 Nov '22

Hello openstack-discuss, I have a designate setup using bind9 as the user-serving DNS server. When starting a machine with either very old or no zones at all, NXDOMAIN or other actually stale data is sent out to clients as designate is not done doing an initial full sync / reconciliation. * What is the "proper" way to tackle this cold-start issue and to keep the bind from serving wrong data? ** Did I miss on any options to handle this startup case? * What is the usual runtime for an initial sync that you observe in case the backend DNS server has no zones at all anymore? Regards Christian

[all] Deprecated Zuul queue syntax
by Clark Boylan 16 Sep '22

16 Sep '22

Hello, Zuul deprecated declaring shared queues at a pipeline level with release 4.1.0 [0]. Zuul's current plan is to stop accepting this form of configuration with a future 7.0.0 release. More details on what needs to change can be found in Zuul's reminder notice on the Zuul mailing list [1]. I expect we have about a month before the v7 release which should give us plenty of time to fix this. If we don't fix this before the v7 release the expected fallout will be that these project branches will not have any pipelines defined, which means no Zuul jobs will run against that project branch until the configs are updated. I've marked this for everyone because 98 repositories are affected, and I'm not sure listing them all in the subject would be productive. Here is the list of affected repos: openstack/adjutant openstack/ansible-collection-kolla openstack/ansible-role-collect-logs openstack/ansible-role-tripleo-modify-image openstack/barbican openstack/barbican-tempest-plugin openstack/barbican-ui openstack/blazar openstack/blazar-tempest-plugin openstack/ceilometer openstack/cinderlib openstack/cloudkitty openstack/cloudkitty-tempest-plugin openstack/cyborg-tempest-plugin openstack/designate openstack/designate-dashboard openstack/designate-tempest-plugin openstack/devstack-gate openstack/ec2-api openstack/ec2api-tempest-plugin openstack/freezer openstack/freezer-tempest-plugin openstack/heat openstack/heat-dashboard openstack/heat-tempest-plugin openstack/horizon openstack/ironic openstack/ironic-inspector openstack/ironic-lib openstack/ironic-prometheus-exporter openstack/ironic-python-agent openstack/ironic-tempest-plugin openstack/kayobe openstack/kayobe-config openstack/kayobe-config-dev openstack/kolla openstack/kolla-ansible openstack/kuryr openstack/magnum openstack/magnum-tempest-plugin openstack/manila openstack/manila-tempest-plugin openstack/masakari openstack/masakari-monitors openstack/mistral openstack/mistral-tempest-plugin openstack/monasca-api openstack/monasca-common openstack/monasca-events-api openstack/monasca-log-api openstack/monasca-tempest-plugin openstack/murano openstack/murano-tempest-plugin openstack/networking-generic-switch openstack/octavia openstack/octavia-tempest-plugin openstack/openstack-chef openstack/os-net-config openstack/os-win openstack/oswin-tempest-plugin openstack/paunch openstack/project-config openstack/puppet-pacemaker openstack/puppet-tripleo openstack/python-designateclient openstack/python-ironicclient openstack/python-saharaclient openstack/python-tripleoclient openstack/python-troveclient openstack/sahara openstack/sahara-tests openstack/senlin openstack/senlin-tempest-plugin openstack/solum openstack/solum-tempest-plugin openstack/telemetry-tempest-plugin openstack/tenks openstack/tripleo-ci openstack/tripleo-ci-health-queries openstack/tripleo-common openstack/tripleo-heat-templates openstack/tripleo-quickstart openstack/tripleo-quickstart-extras openstack/tripleo-upgrade openstack/trove openstack/trove-tempest-plugin openstack/vitrage openstack/vitrage-tempest-plugin openstack/watcher openstack/watcher-tempest-plugin openstack/zaqar openstack/zaqar-tempest-plugin openstack/zun openstack/zun-tempest-plugin windmill/windmill windmill/windmill-backup x/neutron-classifier x/vmware-nsx I'll go ahead and push changes to windmill/* and x/* as those are leftovers from splitting things up into tenants and haven't ended up in their own tenants yet. But it would be great if OpenStack can work on cleaning up this deprecated syntax in the OpenStack repos. I've attached a file with a listing that includes more details for each repo (branches and specific config files) to make it easier for people to find where the old syntax is located so that it can be replaced with the new syntax.

[horizon][plugins] Horizon angular based plugins are broken after migrating to angularjs 1.8.2.2
by vishal manchanda 16 Aug '22

16 Aug '22

Hello everyone, Horizon team recently migrated XStatic-Angular 1.5.8.0->1.8.2.2 [1] and after that many horizon angular based plugins start failing [2]. We already fixed these issues in horizon [3]. So I guess we need to fix the similar thing in horizon plugins. Why did we migrated Angular 1.5.8.0->1.8.2.2? The angularjs version is updated 1.5.8.0->1.8.2.2 to include the CVE fixed in the latest version. Also, there is a security bug reported for the same [4]. I have also created an etherpad to track the progress for failed horizon plugins [5]. Action items for the horizon plugins team either fixed their plugins or review/merge the patch pushed by horizon team members on priority basis to fix the gate. The npm jobs are failing in below horizon plugins : • ironic-ui • octavia-dashboard • senlin-dashboard • designate-dashboard • vitrage-dashboard • murano-dashboard • zaqar-ui • zun-ui • magnum-ui In case of any queries, please feel free to reach out to Horizon channel #openstack-horizon. Thanks & Regards, Vishal Manchanda(irc: vishalmanchanda) [1] https://review.opendev.org/c/openstack/requirements/+/844099 [2] https://review.opendev.org/c/openstack/horizon/+/845733 [3] https://review.opendev.org/c/openstack/horizon/+/843346 [4] https://bugs.launchpad.net/horizon/+bug/1955556 [5] https://etherpad.opendev.org/p/Fix_Horizon_Plugins_With_Angularjs_v1.8.2.2

[tc] August 2022 OpenInfra Board Sync
by Jeremy Stanley 11 Aug '22

11 Aug '22

The Open Infrastructure Foundation Board of Directors is endeavoring to engage in regular check-ins with official OpenInfra projects. The goal is for a loosely structured discussion one-hour in length, involving members of the board and the OpenStack TC, along with other interested community members. This is not intended to be a formal presentation, and no materials need to be prepared in advance. I've started an Etherpad where participants can brainstorm potential topics of conversation, time-permitting: https://etherpad.opendev.org/p/2022-08-board-openstack-sync I've also created a Framadate poll has in order to identify a few preferred dates and times. Responses must be submitted by Friday, 2022-07-15, in order to provide the board members with time to pick from the available options. The poll can be found here: https://framadate.org/atdFRM8YeUtauSgC Feel free to reply here on the mailing list, or you can reach out to me directly by E-mail or as fungi in the #openstack-tc IRC channel, with any questions you may have. -- Jeremy Stanley
