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.

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! Cheers, Tobias

Live migration fails

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

[ptl][tc] OpenStack packages PyPi additional external maintainers audit & cleanup
by Ghanshyam Mann 17 May '24

17 May '24

Hi PTLs, As you might know or have seen for your project package on PyPi, OpenStack deliverables on PyPi have additional maintainers, For example, https://pypi.org/project/murano/, https://pypi.org/project/glance/ We should keep only 'openstackci' as a maintainer in PyPi so that releases of OpenStack deliverables can be managed in a single place. Otherwise, we might face the two sets of maintainers' places and packages might get released in PyPi by additional maintainers without the OpenStack project team knowing about it. One such case is in Horizon repo 'xstatic-font-awesome' where a new maintainer is added by an existing additional maintainer and this package was released without the Horizon team knowing about the changes and release. - https://github.com/openstack/xstatic-font-awesome/pull/2 To avoid the 'xstatic-font-awesome' case for other packages, TC discussed it in their weekly meetings[1] and agreed to audit all the OpenStack packages and then clean up the additional maintainers in PyPi (keep only 'openstackci' as maintainers). To help in this task, TC requests project PTL to perform the audit for their project's repo and add comments in the below etherpad. - https://etherpad.opendev.org/p/openstack-pypi-maintainers-cleanup Thanks to knikolla to automate the listing of the OpenStack packages with additional maintainers in PyPi which you can find the result in output.txt at the bottom of this link. I have added the project list of who needs to check their repo in etherpad. - https://gist.github.com/knikolla/7303a65a5ddaa2be553fc6e54619a7a1 Please complete the audit for your project before March 15 so that TC can discuss the next step in vPTG.

[designate] Proposal to deprecate the agent framework and agent based backends
by Michael Johnson 10 Jan '24

10 Jan '24

TLDR: The Designate team would like to deprecate the backend agent framework and the agent based backends due to lack of development and design issues with the current implementation. The following backends would be deprecated: Bind9 (Agent), Denominator, Microsoft DNS (Agent), Djbdns (Agent), Gdnsd (Agent), and Knot2 (Agent). Designate includes many backend DNS server drivers[1], many of which are "native" (also known as xfr type backends) backend implementations. In addition to the "native" backends, Designate has an agent backend[2] that supports other backends via an agent process. To quote the agent backend documentation[2]: This backend uses an extension[3] of the DNS protocol itself to send management requests to the remote agent processes, where the requests will be actioned. The rpc traffic between designate and the agent is both unauthenticated and unencrypted. Do not run this traffic over unsecured networks. Here are the reasons we are proposing to deprecate the agent framework now: 1. The agent protocol used by Designate is using an "unassigned"[4][5] DNS opcode (14) that is causing problems with the dnspython library >= 2.3.0 which is now validating the opcode when building DNS messages. It is a bad practice to use "unassigned" values as they may be officially assigned at any time, likely with an incompatible message format. 2. The agent backends are not tested in the OpenStack jobs[1]. 3. Many of the agent backends have been marked as "Experimental" since 2016 with no additional contributions beyond general repository code maintenance. 4. The protocol between the Designate worker process and the agent process is unauthenticated and unencrypted. 5. We do not know of a development resource to rewrite the agent framework protocol to address issue #1 and #4 above. 6. The introduction of catalog zones[6] may eliminate the need for some of the agent based backend drivers. By marking the agent framework and agent based backends "deprecated" in the Antelope cycle, we would remove the code no earlier than the "C" release of OpenStack (per the OpenStack deprecation policy[7]). In the meantime, issue #1 has been worked around by overriding the dnspython opcode validation[7] as needed in the Designate code (similar to a monkey patch). This is not a sustainable long term solution. The following backend agent based drivers would be marked "deprecated" in addition to the agent framework itself: Bind9 (Agent) Denominator Microsoft DNS (Agent) Djbdns (Agent) Gdnsd (Agent) Knot2 (Agent) We plan to propose patches for the deprecation over the next week, but will not merge them until at least January 24th to allow time for comment from the community. If you have concerns about this deprecation plan or are interested in rewriting the agent framework protocol to address the above issues, please reply to this announcement.

[ptl][tc][winstackers] Final call for Winstackers PTL and maintainers
by James Page 12 Sep '23

12 Sep '23

Hi All As announced by Lucian last November (see [0]) Cloudbase Solutions are no longer in a position to maintain support for running OpenStack on Windows and have also ceased operation of their 3rd party CI for the windows support across a number of OpenStack projects. This situation has resulted in the Winstackers project becoming PTL-less for the 2023.2 cycle with no volunteers responding to the TC's call to fill this role and take this feature in OpenStack forward (see [1]). This is the final call for any maintainers to step forward if this feature is important to them in OpenStack. The last user survey in 2022 indicated that 2% of respondents were running on Hyper-V so this might be important enough to warrant a commitment from someone operating OpenStack on Windows to maintain these features going forward. Here is a reminder from Lucian's original email on the full list of projects which are impacted in some way: * nova hyper-v driver - in-tree plus out-of-tree compute-hyperv driver * os-win - common Windows library for Openstack * neutron hyperv ml2 plugin and agent * ovs on Windows and neutron ovs agent support * cinder drivers - SMB and Windows iSCSI * os-brick Windows connectors - iSCSI, FC, SMB, RBD * ceilometer Windows poller * manila Windows driver * glance Windows support * freerdp gateway The lack of 3rd party CI for testing all of this really needs to be addressed as well. If no maintainers are forthcoming between now and the next PTG in June the TC will need to officially retire the project and start the process of removing support for Windows across the various projects that support this operating system in some way - either directly or through the use of os-win. For clarity this call refers to the use of the Hyper-V virtualisation driver and associated Windows server components to provide WIndows based OpenStack Hypervisors and does not relate to the ability to run Windows images as guests on OpenStack. Regards James [0] https://lists.openstack.org/pipermail/openstack-discuss/2022-November/03104… [1] https://lists.openstack.org/pipermail/openstack-discuss/2023-March/032888.h…

[openstack-ansible] Recommended branch for a production environment?
by Roger Rivera 05 Sep '23

05 Sep '23

Hello, We have deployed Openstack-Ansible in a test environment and we were wondering what the recommended repository branch is to deploy in a production environment that will be integrated with a separate Ceph cluster. 1. We are thinking about pinning to the stable/zed. Is that recommended over the master branch? 2. Are bugs ironed out on both master and stable/zed with the same cadence? 3. Additionally, is Debian 11 a better alternative than Ubuntu 22 for target hosts? We noticed Ubuntu 22.04 support was added recently, whereas Debian 11 has been supported for quite some time now which leads us to believe its stability/integration could be more mature at this point? Any suggestions will be appreciated. Thank you, -- *Roger *

[puppet] Proposing core team clean up
by Takashi Kajinami 24 Aug '23

24 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

[cloudkitty] question to the scope_key in cloudkitty
by Noah Elias Feldt 28 Jul '23

28 Jul '23

Hello! I am currently trying to get CloudKitty to work with the Prometheus Collector and PyScripts. I noticed that the scope_key for Prometheus can only be changed once in the global configuration file. This was a problem for me because we need different scope_keys for different metrics. Many of the metrics still need the scope key "tenant_id" and some others "project_id". I have found in the documentation of CloudKitty no way to change this for each metric, so I have internally changed something in the source code and added the function to set the scope_key for each metric individually. I just wanted to ask if you would be interested if I submit the small change upstream? Thank you. Regards Noah Feldt

SNAT failure with OVN under Antelope
by Gary Molenkamp 14 Jul '23

14 Jul '23

Good morning, I'm having a problem with snat routing under OVN but I'm not sure if something is mis-configured or just my understanding of how OVN is architected is wrong. I've built a Zed cloud, since upgraded to Antelope, using the Neutron Manual install method here: https://docs.openstack.org/neutron/latest/install/ovn/manual_install.html I'm using a multi-tenent configuration using geneve and the flat provider network is present on each hypervisor. Each hypervisor is connected to the physical provider network, along with the tenent network and is tagged as an external chassis under OVN. br-int exists, as does br-provider ovs-vsctl set open . external-ids:ovn-cms-options=enable-chassis-as-gw For most cases, distributed FIP based connectivity is working without issue, but I'm having an issue where VMs without a FIP are not always able to use the SNAT services of the tenent network router. Scenario: Internal network named cs3319: with subnet 172.31.100.0/23 Has a router named cs3319_router with external gateway set (snat enabled) This network has 3 vms: - #1 has a FIP and can be accessed externally - #2 has no FIP, can be accessed via VM1 and can access external resources via SNAT (ie OS repos, DNS, etc) - #3 has no FIP, can be accessed via VM1 but has no external SNAT connectivity From what I can tell, the chassis config is correct, compute05 is the hypervisor and the faulty VM has a port binding on this hypervisor: ovn-sbctl show ...

[oslo] HTTP base direct RPC oslo.messaging driver contribution
by 室井雅仁 11 Jul '23

11 Jul '23

Hi oslo team, We'd like to contribute HTTP base direct RPC driver to the oslo.messaging community. We have developed the HTTP base driver internally. We have been using the driver in the production with over 10K hypervisors now. I checked the IRC meeting log of the oslo team[1], but there is no regluar meeting in 2023. Is it okay to submit oslo-spec[2] to propose the driver directly, or is there another good place to discuss the feature before submitting a spec? 1. https://meetings.opendev.org/#Oslo_Team_Meeting 2. https://opendev.org/openstack/oslo-specs best regards, Masahito

[ironic] Capping off storyboard migration
by Jay Faulkner 03 Jul '23

03 Jul '23

Hey all, I've written a small tool[1] which should (I think; I can't test it all the way until I'm ready to actually change a thing) iterate through stories in a storyboard project, and close any open tasks as invalid with a message. I'd like to point this script at all the Ironic-related Storyboard projects, closing all the issues with a message like the following: "Hello Ironic contributor, thank you for filing this bug! We have migrated to the Launchpad bugtracker, located at https://bugs.launchpad.net/ironic, If this bug remains valid, please open an issue in launchpad with the URL to this story for context." Are folks onboard for having all the tasks closed as invalid in these Ironic-related projects? Any feedback on the messaging? Thanks, Jay Faulkner P.S. For other projects who might want to use the tool as well, wait until I use it for Ironic to help me smooth out any rough edges and then have at it! 1: https://github.com/jayofdoom/sb-issue-closer

[Neutron] Tap as a service
by altidor JB 03 Jul '23

03 Jul '23

Hello, Can anyone help me with the setup of Tap as a Service on Openstack with Juju and Maas? I've seen tutorials for installing it on DevStack but nothing for large scale setups. So far I've tried doing a similar process to this: https://zhuanlan.zhihu.com/p/101599786 basically install the apt on the neutron_api lxd and on the compute nodes, with configurations that are done in the above tutorial. Sounds simple enough. But the tap_services and tap_flows stay in Down state. Any ideas??? Also I'm open to another way to do port mirroring if this doesn't work. JB
