overload factor tunning
by pikajorge＠gmail.com 01 May '24

01 May '24

Greetings Folks! My name is Jorge! and currently I'm tunning a policy, in the past due to a lack of hardware the overload factor was set to 320.00% (3.200000) since we are in the process of reducing the number of the replicas (currently 3.56) to three and also When running: swift-ring-builder object-90210.builder dispersion Dispersion is 0.000000, Balance is 234.102882, Overload is 320.00% Required overload is 233.738772% It's suggesting us to decrease the overload factor, nonetheless if a rebalance is run, this value is once again calculated, and it has suggested 1000%, kindly I'd like for your assistance to help me understand first, how can I estimate the overload factor, and also considering the number of desired replicas and our capacity, how can I set the overload factor to be optimum? or is this a value that will need to be modified everytime? . Thanks in advance for all your help! Warmest regards Jorge!

[barbican][requirements] Request to Include Barbican Installation Guide in OpenStack-Helm Documentation
by Renu Rani 01 May '24

01 May '24

Hi dear colleagues, We are presently in the process of enhancing the official OpenStack-Helm documentation by including a procedural guide for deploying Tacker using helmchart. Through discussions with members of the openstack-helm community, it has been emphasized that Barbican is an indispensable component for Tacker. Hence, it would be highly beneficial for users to have comprehensive instructions for installing Barbican with helmchart included in the official OpenStack-Helm documentation [1]. Consequently, we suggest that the Barbican community integrate the installation guide for the Barbican component into the official OpenStack-Helm documentation. This addition is poised to significantly enhance the clarity and accessibility of deployment procedures for users. We eagerly welcome your opinions and feedback on this proposal, as we aim to ensure that the documentation for openstack deployment with helmchart meets the needs of our community.

[dev][requirements] Potentially ceasing development of Paste
by Jeremy Stanley 01 May '24

01 May '24

Just a heads up that Chris is raising concerns about continued maintenance of the Paste library, which more than a few of our projects rely on: https://github.com/cdent/paste/discussions/91 It's worth considering whether we would offer to adopt/fork it or if there are straightforward migration paths to actively maintained alternatives. -- Jeremy Stanley

Upgrade Bobcat/Caracal and python3-futurist
by Francesco Di Nucci 30 Apr '24

30 Apr '24

Hi all, I'm upgrading from Bobcat to Caracal using RDO repositories. I noticed that the package python3-futurist.noarch was present in centos-openstack-bobcat repo, but it is not in openstack-caracal. So it is not possible to update/reinstall/etc. it as it is "orphaned" once the bobcat repository is disabled. Should it be removed? Is it still a dependency? Best regards Francesco Di Nucci

Hi, After upgrading a compute server from Yoga/EL8 to Antelope/EL9, I cannot start VM on it. nova-compute log says: ---- Failed to build and run instance: libvirt.libvirtError: unsupported configuration: domain configuration does not support video model 'virtio' ---- According to https://bugs.launchpad.net/nova/+bug/2018172, it seems the problem also existed when trying to deploy nova-compute Yoga/Zed on EL9 but what fixed the problem is not clear in the issue...

[Horizon][Skyline][API] Recommendation for a Web Application Firewall in front of Services
by Kaster, Jörn 30 Apr '24

30 Apr '24

Hello together, are there any recommendations or best practices how to expose the openstack API and/or WebUI's over a WAF (web application firewall) to the internet? We think we would use VMware NSX ALB [1] for this, but with the current broadcom trouble in the VMware sphere, we are uncertain for the future with this product. Are there any alternative software tools to reach the waf functionality to secure the api and http path's to openstack? regards Jörn [1]https://docs.vmware.com/en/VMware-NSX-Advanced-Load-Balancer/index.html [https://docs-prod.vmware.com/en/VMware-NSX-Advanced-Load-Balancer/images/GU…]<https://docs.vmware.com/en/VMware-NSX-Advanced-Load-Balancer/index.html> VMware NSX Advanced Load Balancer Documentation<https://docs.vmware.com/en/VMware-NSX-Advanced-Load-Balancer/index.html> Welcome to the VMware NSX Advanced Load Balancer (formerly known as Avi Networks).

[neutron] neutron-dynamic-routing advertising IPv4 AND IPv6 routes for true MP-BGP OR running multiple BGP speakers per agent (host)?
by Christian Rohmann 30 Apr '24

30 Apr '24

Hello OpenStack-Discuss, when setting up Neutron Dynamic Routing [1] to advertise IPV4 floating IPs and also IPv6 tenant networks I ran into some questions / issues. I was just about to ask about them here on the ML, when I found the older thread [2] discussing the advertising of IPv6 routes (e.g. from tenant networks). There Sean mentioned [4] that even with MP-BGP support [3] it's required to have two BGP speakers. While [3] means IPv4 or IPv6 can be used to establish the BGP session itself to then advertise routes for either address family, it's not possible to advertise IPv4 AND IPv6 routes via the same session. To cut to the chase of this threat .... It's not uncommon to simply use individual (non Multi-Protocol) BGP sessions to exchange routes for IPv4 and IPv6 individually and to me this poses no issue to me. The problem with Neutron is though, that the os_ken dragent driver only supports one BGP speaker [5] per agent. This leads to only one of the BGP speakers (IPv4 or IPv6) running per individual (control plane, networking) host. Or am I not seeing something or am misreading the capabilities of the components involved? If not, I see two options for improvement here: 1) Enabling a BGP speaker to have more than one address family (dragent driver already has MP-BGP support via [3]), so the query fetching the routes [6] simply returns them both. 2) Somehow get more than one BGP speaker per dragent working by ... a) ... extending the driver to host more than one BGP speaker b) ... extending dragent to have more than one driver instance Would love to hear how others have set up their dynamic routing and what your ideas are!

[tc][all] OpenStack Technical Committee weekly summary and meeting agenda
by Goutham Pacha Ravi 30 Apr '24

30 Apr '24

Hello Stackers, We're slowly approaching Milestone-1 of the 2024.2 (Dalmatian) release cycle [1]. As you observe, there is a buzz of activity across all OpenStack repositories as we've just gotten out of our design and planning event. I hope you've been enjoying the PTG summaries that have been posted thus far; I would especially recommend reading through the summary JayF put up for the Technical Committee meetings [2]. Allow me to take you through the latest news from the Technical Committee: === Weekly Meeting === Last week's TC meeting was held on IRC on Apr 23rd, 2024. The meeting was logged to eavesdrop [3]. Our main topic of discussion was about the fate of unmaintained branches, and the discussion was timely given that Elod Iles from the OpenStack Release Management SIG brought a discussion to this list about transitioning the "stable/zed" branch of all release-cycle deliverables to "unmaintained/zed" [5]. This process is underway [6]. Concerns were expressed that the unmaintained process may be easy for teams to opt in, and the burden on the "unmaintained-core" team is growing with each branch. Project Teams are expected to actively assist in transitioning branches to end-of-life. Since this isn't happening, and since the TC has noted that a number of projects have CI (Zuul) configuration errors on these "unmaintained" branches, it was proposed that we be aggressive about proposing end-of-life for unmaintained branches. It was also argued that our release model is going too fast for real-world deployments to catch up, and transitioning a lot of branches simultaneously to EOL may impact many consumers. In the interest of time during the meeting, we decided not to interfere with the transition of stable/zed to "unmaintained/zed". We encourage project leaders to: - Get their CI configuration in order for any unmaintained branches - If there is no interest/time to maintain any unmaintained branch, please actively pursue the branch's EOL process [7] In the rest of the meeting, we went through open governance proposals. We have been distracted by the PTG and Action Items across OpenStack, so some of these proposals are lacking review attention. We'll be focusing on getting these adequate review attention in the coming week/s. The next TC meeting is today, Apr 30th, 2024, at 1800 UTC on OFTC's #openstack-tc channel [4]. The agenda feels light, but we'll try to address a number of TC trackers at this meeting. This meeting is enhanced by the community's participation. We'd especially invite project leaders (PTLs, DPLs, Core maintainers) to participate and propose topics. === Goal Proposals === I'd like to request a community review of the following OpenStack community goals and updates: - Migrate eventlet usages to asyncio (https://review.opendev.org/c/openstack/governance/+/902585) - Goal: Remove eventlet requirements from shared libraries (https://review.opendev.org/c/openstack/governance/+/916546) - Add timeline to remove enforce_scope in RBAC goal (https://review.opendev.org/c/openstack/governance/+/915179) === Governance Proposals === The following governance proposals are close to being merged: - Add option to move leaderless project to Inactive status (https://review.opendev.org/c/openstack/governance/+/914726) - Appoint Wenxiang Wu as PTL of Skyline | (https://review.opendev.org/c/openstack/governance/+/915108) - Transition Freezer project to DPL | (https://review.opendev.org/c/openstack/governance/+/914911) The following governance proposals are actively being discussed: - Add DPL model & liaison reset policy (https://review.opendev.org/c/openstack/governance/+/916833) - Update to include docs and miscellaneous repos for AC status (https://review.opendev.org/c/openstack/governance/+/915021) - Clarify the timeline for a project to move to Inactive state (https://review.opendev.org/c/openstack/governance/+/908880) The following governance proposals need some review attention: - Move openstack/kuryr and openstack/kuryr-libnetwork to Zun (https://review.opendev.org/c/openstack/governance/+/917517) - 2023 User Survey TC Question Analysis (https://review.opendev.org/c/openstack/governance/+/900516) And finally, please consider volunteering as an Election official for the next OpenStack elections!

[all][oslo] Removing Python 3.8 support
by Takashi Kajinami 29 Apr '24

29 Apr '24

Hello, I'm sending this to remind you of the fact that Python 3.8 support will no longer be part of the tested python versions for 2024.2 . Based on the plan, I'll drop Python 3.8 support from all oslo libraries and update the minimum python version from 3.8 to 3.9, in the final release of oslo deliverables. Please make sure that none of the master jobs are dependent on Python 3.8 . We faced some problems when we first attempted to remove python 3.8 support early and the removal was eventually reverted because of remaining usage of Focal and remaining lifecycle of Python 3.8. However now Python 3.8 is actually reaching its EOL, we may no longer attempt the same revert. https://governance.openstack.org/tc/reference/runtimes/2024.2.html Thank you, Takashi Kajinami -- Takashi Kajinami irc: tkajinam github: https://github.com/kajinamit launchpad: https://launchpad.net/~kajinamit

[tc][election] A call for election officials for 2024.2
by Goutham Pacha Ravi 29 Apr '24

29 Apr '24

Hello Stackers, I'd like to express my gratitude to Ian Y Choi and Tony Breeds for their service as OpenStack's election officials for the 2024.1 term. A hallmark of our community has been its leadership and the guiding principles [1] we use when defining them. In Aug-Sep 2024, we're going to be electing the next set of OpenStack Project Team Leads as well as 4 members of the OpenStack Technical Committee. We've run a combined election for PTLs and TC seats in the past few years. We envision doing the same for this upcoming election. Most of the election process is automated, and election officials help execute and oversee this process [2]. If you're interested in being an election official, please reach out to me. If you've previously served as an election official, please do not hesitate to reach out. If we have enough volunteers, you may do us a great favor by mentoring those doing this for the first time. Thank you, Goutham Pacha Ravi (gouthamr) OpenStack TC Chair [1] https://governance.openstack.org/tc/reference/principles.html [2] https://governance.openstack.org/election/process.html

[magnum][magnum-capi][cinder] Override csi plugin to override availability zone for cinder
by Satish Patel 29 Apr '24

29 Apr '24

Folks, I have deployed a magnum with magnum-capi driver. Now trying to work with a cinder for PV stuff and found some strange issue related to the Availability Zone. My k8s cluster running in AZ: foo My Ceph/Cinder running in AZ: nova (default) I have created k8s cluster using magnum-capi selecting AZ: foo but when I am trying to create/attach PV then getting an error saying invalid AZ. Ofc because its in different AZ so I have add following snippet in Storage class to override AZ of CSI allowedTopologies: - matchLabelExpressions: - key: topology.cinder.csi.openstack.org/zone values: - nova PV creation completed successfully after applying the above change. Now when I try to deploy ngnix and pass that PV then again I get a volume affinity issue because worker nodes and volume are in different AZ. I did the following to change CSI plugin az to nova for worker node to make it fix. kubectl label nodes kube-acrsf-default-worker-rxmg6-t7wzd topology.cinder.csi.openstack.org/zone=nova --overwrite What is the proper workaround here for the above scenario and what would be the proper way to fix it? Does magnum have Cinder CSI AZ label to override availability zone in magnum template?

[ironic][nova-scheduler] "host_state" in nova filters has stale aggregate information
by Michael Sherman 29 Apr '24

29 Apr '24

Hi all, We’re running into an issue, where for two sites with 150-250 ironic nodes on a single conductor and nova-compute instance, we’ve started to get “no hosts available” errors from nova scheduler. We’re using the blazar-nova filter to match on hosts in specifically tagged aggregates. After adding some debug logs, I found that the “host_state” object passed to the filter seems to have out-of-date aggregate information. Specifically, if I query the system with “openstack aggregate show …” or “openstack allocation candidate list”, I see the correct aggregate for the nodes in question, but the contents of “host_state” reflect a previous state. This “staleness” does not seem to correct itself over time, but is resolved by restarting the nova-scheduler process (actually restarting the kolla docker container, but the same effect). However the issues return over the course of a couple hours. We haven’t increased the number of nodes, or otherwise changed the hardware, so I’m not sure what could have triggered this issue. Any advice on further debugging steps would be greatly appreciated. Thank you! -- Michael Sherman Infrastructure Lead – Chameleon Computer Science, University of Chicago MCS, Argonne National Lab

I have added a sudoers entry on the like of the nova one: neutron ALL = (root) NOPASSWD: /usr/bin/neutron-rootwrap /etc/neutron/rootwrap.conf * But I don't know if it is correct, is there any documentation about it?

Losing connection when connecting br-ex to bond
by sarasoltanm2000＠gmail.com 28 Apr '24

28 Apr '24

The problem started from where I realized I couldn't ping or ssh the instances in openstack then I realized that it was a networking problem and that br-ex was not connected to my interfaces. for some reason I had to create a bond with a static private ip address of the second interface. (172.16.8.2/24). so to solve this problem I tried to connect the bond to the br-ex but as soon as I connect the bond to br-ex I get disconnected from the server (server cannot ping its gateway) and br-ex state goes down, when I connect it to the bond by the following command: sudo ovs-vsctl add-port br-ex bond0 and when I try to bring the bridge br-ex back up, the bond is automatically deleted from the ports. this is the configuration of bridges before adding the bond port: #ovs-vsctl show Manager "ptcp:6640:127.0.0.1" is_connected: true Bridge br-ex Controller "tcp:127.0.0.1:6633" is_connected: true fail_mode: secure datapath_type: system Port phy-br-ex Interface phy-br-ex type: patch options: {peer=int-br-ex} Port br-ex Interface br-ex type: internal Bridge br-int Controller "tcp:127.0.0.1:6633" is_connected: true fail_mode: secure datapath_type: system Port br-int Interface br-int type: internal Port "tapf556c-c7" tag: 1 Interface "tapf556c-c7" type: internal Port "tapd2980-19" tag: 4095 Interface "tapd2980-19" type: internal Port "qr-8ea26-da" tag: 4095 Interface "qr-8ea26-da" type: internal Port "tap89cc3-c0" tag: 2 Interface "tap89cc3-c0" type: internal Port int-br-ex Interface int-br-ex type: patch options: {peer=phy-br-ex} ovs_version: "2.12.0" any idea why this happens and what is the solution? btw the instance is not connected to a router and it is basically connected to 2 networks (172.16.8.32/28 and 172.16.8.48/28)

[Neutron] Openvswitch forcing MTU 1450
by Karl Kloppenborg 27 Apr '24

27 Apr '24

Hey Neutron team. I have an issue where within the VXLAN network of tenancies the expected 1500 MTU is honoured but despite all MTU in the underlay being 9k and all networks and paths set to 1500, Openvswitch caps the MTU transiting north/south to 1450. This is causing considerable pain to some of our customers and despite trying to force the openvswitche bridges request_mtu to 1500, and all interfaces look right, it’s still caping at 1450. Note, TCP dumps show the pings set to 1500 getting to the network namespace on the openvswitch agent, so it appears something between the nat/snat process. VM1 private -> VM2 private (mtu 1500) = works VM1 private -> VM2 public (mtu 1500) = fails VM -> External (mtu 1500) = fails External Host -> VM (mtu 1500) = fails Adusting to 1422 on ping sizes works. Anyone experienced this? I cannot seem to make heads or tails of it. Thanks, Karl.

[nova] allow only specific instances on host aggregate
by Eugen Block 26 Apr '24

26 Apr '24

Hi, I'm playing around with host aggregates and the aggregate_instance_extra_specs for flavors. I successfully created a host aggregate, it allows me to schedule instances with a specific flavor on that aggregate only. But is there a way to prevent other VMs from starting on that aggregate (which were launched with different flavors)? The only thing coming to mind is to put that compute node(s) into a different availbility zone. Since the default is "nova", this would prevent anything else to start on that hypervisor. Is there anything I missed with aggregates? Any pointers are appreciated! Thanks! Eugen
