Query on Enabling Horizon Support for Creating SR-IOV VMs
by Aditya Sathish 29 Aug '23

29 Aug '23

Hello, We have enabled SR-IOV external interfaces on our server cluster running OpenStack Yoga. Unfortunately, there is a known limitation on the Horizon dashboard where we cannot create virtual machines through the dashboard - forcing us to rely on the OpenStack CLI to create the VMs. I wanted to understand what precisely the limitation was to support this from Horizon and if there were any cherry-picks I could pull from the later releases that would allow me to provide this support through the dashboard (or upgrade my release to 2023.1). I did see that we can now select the VNIC_Type from the dashboard, but that doesn't resolve the issue of VM creation with SR-IOV ports. Any points would be greatly appreciated. Regards, Aditya

[kolla] using local package mirror for image builds
by Jonathan Proulx 29 Aug '23

29 Aug '23

HI All, Using `kolla-build -b ubuntu` to build container images keeps timing out (well hanging for literal days) seemingly on package downloads from remote mirrors. I'm new to kolla and kolla-ansible so I may be misdiagnosing the cause of my current issue but we de have local ubuntu package mirros which would be faster in any case. Is there a way to specify using only a local package mirror? Thanks, -Jon

[Neutron] Default gateway for IPv6 is 0
by Xing Zhang 29 Aug '23

29 Aug '23

Hello everyone, In my test environment, I noticed that the default gateway for IPv6 is changed from 1 to 0, is this correct? Reproduce steps are: * openstack cli: openstack network create test-ipv6-net openstack subnet create --subnet-range 2001:db8::200:0/64 --ip-version 6 --ipv6-ra-mode dhcpv6-stateful --ipv6-address-mode dhcpv6-stateful --network test-ipv6-net test-ipv6-subnet # the gateway_ip in the output is 2001:db8::200: but 2001:db8::200:1 is the expected IP * neutron cli: neutron net-create test-v6 neutron subnet-create --name test-v6-subnet --ip-version 6 test-v6 2002:db8::200:0/64 # the gateway_ip in the output is 2001:db8::200: but 2001:db8::200:1 is the expected IP there are 3 versions of OpenStack I've tested, the results are: OpenStack Rocky: 2001:db8::200:1 OpenStack Train: 2001:db8::200:1 OpenStack Wallaby: 2001:db8::200: the virtual router will use the gateway ip for port, and some hardware networking sdn controller for neutron may not work.

[ptls][tc] OpenStack User Survey Updates
by Allison Price 29 Aug '23

29 Aug '23

Hi Everyone, Like Helena mentioned last week, we are closing the 2023 OpenStack User Survey in a few weeks and will then open the 2024 OpenStack User Survey. At this time, we want to offer the project teams and TC the opportunity to update your project specific questions that appear at the end of the survey. As a reminder, for the project-specific questions, these appear if a survey taker selects your project in their deployment and TC questions appear to all survey takers. If you and your team would like to update the question, please let me know by Friday, August 18. I know that this is a holiday time for many, so if any team needs some extra time, just let me know. I am also able to share the existing questions with any team that needs a refresher on what is currently in the survey. In the meantime, please continue to promote openstack.org/usersurvey to anyone (and everyone!) you know who is running OpenStack or planning to in the future. We want to get as much feedback as we possibly can. Cheers, Allison

[nova][election] Self-nomination for 2024.1 Nova PTL
by Sylvain Bauza 28 Aug '23

28 Aug '23

Hey Nova and Placement folks, Yet again, I'm asking you to put myself on the Nova and Placement PTL seat. For the exact same reasons than last time (see my previous nomination e-mail), I was convinced to run again for this position, which hopefully will be the last one (despite having already said it once). Challenges are still upfront. Our gate is still coughing every single day and despite the excellent work that a very few awesome people did on stabilizing and which helped improving the situation (kudos to those who will recognize themselves), we are still urging to fix the most common patterns. As a PTL, I'll ensure to keep the energy to chase those issues and identify them so as a team we can fight them. Another concern to me is the reviewing pace. While we're continuing to deliver solid reviews on feature proposals and patches, our team isn't much evolving and we need fresh blood. In order to be able to deliver things, we need to ensure that we properly recognize those who dedicate a portion of their daytime to help others by providing valuable feedback (and I stress on the fact that this feedback *has to* be valuable in order to by worthy). As a PTL, I'll continue to encourage people to express their thoughts and concerns into Gerrit comments so that we are able to count on. The last challenge I have to mention here is the release cadence. Now that more people are getting noticed of the SLURP cadence, we'll be awaited on delivering our next SLURP release, which will be 2024.1 (Caracal). I'll take special attention to that, ensuring that our skip-level-upgrade process we have in Nova will conveniently work with Caracal and that our release notes correctly include the upgrade steps for those who skip 2023.2 (Bobcat). I'll just finish on a last word. While I really appreciated acting as a PTL for the last 4 cycles, I'd be more than happy if someone would like to step up and compete for the seat. I personnally prefer expansion over attrition and one of my favourite tasks is mentoring. Thanks, -Sylvain

TripleO deployment over IPV6
by Kushagr Gupta 25 Aug '23

25 Aug '23

Hi Team, We were trying to perform IPV6-based deployment of TripleO. We are following the link: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16… As per our environment, we set the "ipv6_address_mode" to "dhcpv6-stateful" and tried undercloud deployment. It was successful. But when we try node introspection, openstack is not providing an IP that will be used for PXE booting the system. We have enabled PXE booting on the IPV6 network. On Dell machines, we get the following error: "PXE-E16: No offer received." For your reference, the undercloud file which we used is attached. We also tried to find the communication happening on the br-ctlplane interface when the machine tries to boot over IPV6 PXE boot. I am attaching those tcpdump records as well. We are unable to find the MAC address of our machines. *Questions:* 1. Is it even possible to perform tripleO deployment with IPV6? 2. Do we need to do some extra settings, so that our baremetal machines can be PXE booted? Thanks and Regards

Live migration between centos and ubuntu compute nodes
by Jim Kilborn 25 Aug '23

25 Aug '23

Openstack peers: I am migrating our production openstack environment from centos7 to ubuntu. I am on the train release currently, so I can have that release on both centos7 and ubuntu 18 The issue is that I need to live migrate the vms if it's possible. When I try, I get an error on the source compute node (centos 7). Live Migration failure: Cannot check QEMU binary /usr/libexec/qemu-kvm: No such file or directory: libvirtError: Cannot check QEMU binary /usr/libexec/qemu-kvm: No such file or directory Any ideas how to get around this until I get my vms migrated? Maybe create a link on the ubuntu 18 host? I'm sure I am not the first to leave centos 7 for ubuntu Thanks for any help on this.

[release] Release countdown for week R-5, Aug 28 - Sep 01
by Thierry Carrez 25 Aug '23

25 Aug '23

Development Focus ----------------- We are getting close to the end of the 2023.2 Bobcat cycle! Next week on August 31st is the bobcat-3 milestone, also known as feature freeze. It's time to wrap up feature work in the services and their client libraries, and defer features that won't make it to the 2024.1 Caracal cycle. General Information ------------------- This coming week is the deadline for client libraries: their last feature release needs to happen before "Client library freeze" on August 31st. Only bugfix releases will be allowed beyond this point. When requesting those library releases, you can also include the stable/2023.2 branching request with the review. As an example, see the "branches" section here: https://opendev.org/openstack/releases/src/branch/master/deliverables/pike/… August 31st is also the deadline for feature work in all OpenStack deliverables following the cycle-with-rc model. To help those projects produce a first release candidate in time, only bugfixes should be allowed in the master branch beyond this point. Any feature work past that deadline has to be raised as a Feature Freeze Exception (FFE) and approved by the team PTL. Finally, feature freeze is also the deadline for submitting a first version of your cycle-highlights. Cycle highlights are the raw data that helps shape what is communicated in press releases and other release activity at the end of the cycle, avoiding direct contacts from marketing folks. See https://docs.openstack.org/project-team-guide/release-management.html#cycle… for more details. Upcoming Deadlines & Dates -------------------------- Bobcat-3 milestone (feature freeze): August 31st (R-5 week) RC1 deadline: September 14th (R-3 week) Final RC deadline: September 28th (R-1 week) Final 2023.2 Bobcat release: October 4th, 2023 -- Thierry Carrez (ttx)

[ptl][election][neutron] PTL candidacy for 2024.1
by Brian Haley 24 Aug '23

24 Aug '23

Hello Openstack Community, I am writing to submit my candidacy for the Neutron PTL position during the 2024.1 cycle. I have worked on Openstack since Diablo (2011), starting as a cloud operator doing L2 overlay development, along with agent performance and scalability on large-scale deployments. During that time I've become a core contributor (2015) and been part of the team making sure our stable branches continue to receive all the back-ports necessary to make downstream consumption easier. I currently work for Canonical in their Sustaining Engineering group, primarily addressing customer issues, with a focus on processes and tools to help us more quickly solve them. My priorities as PTL would be the following: * Always make sure the stable branches are consumable downstream. Distros and operators are, in my opinion, the lifeblood of Openstack, so we have to make sure they are top of mind when fixing bugs, and that back-ports are done in a timely manner. * Continue pursuing CI stability. During the past 6+ cycles the Neutron community has done a great job keeping its CI healthy, as well as actively updating jobs to make sure we use resources wisely and reduce re-checks. * Keep working on, or complete, ongoing specs. There are a number of larger specs that have a great deal of development in progress, I know we can get some of these completed this cycle: ** Active-active L3 Gateway with Multihoming (LP #2002687) ** Multiple back-end support for L3 routers in ML2/OVN (LP #2020823) ** Configurable Security Group rules added by default to new Security Groups (LP #1983053) ** ML2/OVN IPv6 Distributed routing (LP #1998609) * Continue reducing the bug backlog. Over the past few cycles we were able to fix and/or close about 1/3 of our backlog (~400 bugs), but it will slowly creep back up if we let it. We also have to continue looking forward by: * Keeping the Neutron stadium ecosystem alive and healthy. There are a number of diverse projects, some without a large number of resources. We must make sure those communities receive whatever help they need, whether it's making sure we address bugs affecting them, or helping keep their CIs green. * Address any SQLAlchemy 2.0 migration issues detected. We have done a great job during the last few releases with this work, let's keep that up in 2024.1. * Starting development on newly proposed specs ** OVN interconnection (LP #2027742) * Always welcoming new contributors. Thanks for your support. -Brian Haley (haleyb, haleyb.dev(a)gmail.com)

[neutron][tap-as-a-service][release] Deletion old branches of taas
by Rodolfo Alonso Hernandez 23 Aug '23

23 Aug '23

Hello: I would like to revive the mail sent by Lajos about this topic: https://lists.openstack.org/pipermail/openstack-discuss/2022-November/03127…. In a nutshell: we don't have releases from Ocata to Stein of TaaS because it was moved out from the stadium projects. However we still have issues with the zuul configs. Because we can't release an EOL patch, I would ask the release team to remove these 5 branches (Ocata, Pike, Queens, Rocky and Stein) from the git repository. If that is not possible, I'll send patches to these branches to remove the .zuul file. Regards. [1]https://zuul.opendev.org/t/openstack/config-errors

[ovn] VM in external network unable to arp
by Justin Lamp 22 Aug '23

22 Aug '23

Hey, we are using OVN 22.03 and face an issue where a VM that is directly connected to the provider network won't be accessible, because it cannot arp for the Gateway IP. OVN routers do reply to the arp request though. We know that this exact scenario works as we have it running in our staging environment. Oddly enough if the right MAC-IP Binding is manually defined within the VM and the Gateway, the traffic will begin to flow correctly according to the right SGs. I did an ovn-trace and were able to see that the traffic is supposed to be flooded to the right ports. The ovs-trace on the other hand did not show the same picture. It just did 4k recirculations and then dropped the packet. I already restarted the ovn-controller on the right hv, but that did not do anything.

Hi All, We have an openstack ansible stein version setup. We had a vm on it which we deleted. The associated neutron port was also deleted and the vm uuid is gone from the nova as well. It had a provider network ip. Even after deleting the vm, we are still finding that ssh port 22 on that IP is responding. So I logged into the hypervisor (compute node) on which that vm was there before deletion and found that the libvirtd service was is error state with the following logs in the nova-compute service: --------- 2023-08-18 10:08:51.463 12587 INFO nova.service [-] Starting compute node (version 19.3.2) 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host self.force_reraise() 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host File "/openstack/venvs/nova-stein-em/lib/python2.7/site-packages/oslo_utils/excutils.py", line 196, in force_reraise 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host six.reraise(self.type_, self.value, self.tb) 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host File "/openstack/venvs/nova-stein-em/lib/python2.7/site-packages/nova/virt/libvirt/host.py", line 442, in _get_connection 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host self._wrapped_conn = self._get_new_connection() 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host File "/openstack/venvs/nova-stein-em/lib/python2.7/site-packages/nova/virt/libvirt/host.py", line 396, in _get_new_connection 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host wrapped_conn = self._connect(self._uri, self._read_only) 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host File "/openstack/venvs/nova-stein-em/lib/python2.7/site-packages/nova/virt/libvirt/host.py", line 252, in _connect 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host libvirt.openAuth, uri, auth, flags) 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host File "/openstack/venvs/nova-stein-em/lib/python2.7/site-packages/eventlet/tpool.py", line 148, in proxy_call 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host rv = execute(f, *args, **kwargs) 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host File "/openstack/venvs/nova-stein-em/lib/python2.7/site-packages/eventlet/tpool.py", line 129, in execute 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host six.reraise(c, e, tb) 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host File "/openstack/venvs/nova-stein-em/lib/python2.7/site-packages/eventlet/tpool.py", line 83, in tworker 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host rv = meth(*args, **kwargs) 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host File "/openstack/venvs/nova-stein-em/lib/python2.7/site-packages/libvirt.py", line 104, in openAuth 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host if ret is None:raise libvirtError('virConnectOpenAuth() failed') 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host libvirtError: Failed to connect socket to '/var/run/libvirt/libvirt-sock': Connection refused 2023-08-22 14:28:07.670 12587 ERROR nova.virt.libvirt.host 2023-08-22 14:28:07.676 12587 ERROR oslo_service.service [req-4108e9e2-2afd-472e-a4d9-fcccffc380dc -
