[openstack-ansible]: GPU passthrough
by Rambo Rambo 22 Jan '25

22 Jan '25

Hi Experts Release: Wallaby Distribution: Openstack-ansible I am working on enabling GPU computes through PCIpassthrough: I managed to test the GPU PCI passthrough with the direct configuration below. *GPU compute:* /etc/nova/nova.conf [pci] device_spec = { "vendor_id": "10de", "product_id": "25b6" } passthrough_whitelist = { "vendor_id": "10de", "product_id": "25b6" } alias = { "vendor_id": "10de", "product_id": "25b6", "device_type": "type-PCI", "name": "nvidia" } *Nova API container:* /etc/nova/nova.conf enabled_filters = AvailabilityZoneFilter,ComputeFilter,AggregateNumInstancesFilter,AggregateIoOpsFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter,NUMATopologyFilter, *PciPassthroughFilter* [pci] alias = { "vendor_id": "10de", "product_id": "25b6", "device_type": "type-PF", "name": "nvidia" } Now I need to put the configuration through openstack-ansible. So I need support for the same. *compute:* I intend to use hostvar for the compute configuration: /etc/openstack_deploy/host_vars/compute-<>.yml Can someone please confirm the parameters I need to set in this file and how to implement it? device_spec = ? passthrough_whitelist = ? nova_pci_alias: - '{ "name": "nvidia", "product_id": "25b6", "vendor_id": "10de" }' =====> how can I add *device_type field* here as per the mail.yaml it only have name,product_id and vendor_id field? Run openstack-ansible os-nova-install.yml --tags nova-config --limit <compute name> *For nova_api configuration,* I intend to use below: Below parameter in the user_variable file nova_scheduler_default_filters: - AvailabilityZoneFilter - ComputeFilter - AggregateInstanceExtraSpecsFilter - AggregateNumInstancesFilter - AggregateIoOpsFilter - ComputeCapabilitiesFilter - ImagePropertiesFilter - ServerGroupAntiAffinityFilter - ServerGroupAffinityFilter - NUMATopologyFilter - PciPassthroughFilter nova_pci_alias: - '{ "name": "nvidia", "product_id": "25b6", "vendor_id": "10de" }' =====> how can I add *device_type field here* as per the mail.yaml it only have name,product_id and vendor_id field? Execute: openstack-ansible os-nova-install.yml --tags nova-config --limit <nova api containers> Regards

[magnum] Proposing Jakub Darmach as core reviewer
by Michał Nasiadka 22 Jan '25

22 Jan '25

Hello, I’d like to propose Jakub Darmach (jakub(a)stackhpc.com) as a core reviewer. He has spent quite a good deal of time to get unmaintained branches CI in a green state. He has also contributed some Heat driver patches in the past and is actively reviewing patches (also going the extra mile of updating these patches to be mergable when the author is not available/responsive).

[nova] Seeking Advice on Adding Multiple CPU Models in One Aggregate for OpenStack
by mina.mohammadi367＠gmail.com 21 Jan '25

21 Jan '25

Hello friends, I am currently working on a deployment scenario in OpenStack where I need to group multiple CPU models within a single aggregate. I’m reaching out to the community to ask if anyone has experience with this type of setup or has any advice on best practices. I would greatly appreciate any input from the community regarding potential challenges or recommendations for managing multiple CPU models within a single aggregate. In particular, any advice on ensuring compatibility and optimizing instance scheduling based on traits would be extremely valuable. For reference, I am considering the solution outlined in the CPU Model Selection documentation: https://specs.openstack.org/openstack/nova-specs/specs/train/implemented/cp… Thank you in advance for your time and assistance.

Assistance with Configuring fdb_age_threshold in OVN with Kolla-Ansible
by Jan Wasilewski 21 Jan '25

21 Jan '25

Hi Stackers, Over the past few days, we encountered an issue during the migration of VMs from a customer environment to our OpenStack cloud. Both environments were connected via a cross-connect network (a VLAN-type network spanning the cloud and the customer environment), which resulted in duplicate MAC addresses in our OVN database. This occurred because the migrated VM retained the same MAC address as previously used in the customer's environment(so "ovn-sbctl list fdb" returned a port which was no-longer used and leads to such duplication) . To address the issue, we used the following command to clear the FDB database: ovn-sbctl --all destroy fdb While researching further, we came across the `fdb_age_threshold` configuration [1], which seemed to be a useful feature to prevent similar issues in the future. We attempted to implement it in our Kolla-Ansible environment by adding the following configuration to ` */etc/kolla/config/neutron/ml2_conf.ini*`: [ovn] fdb_age_threshold = 920 After deploying the changes, however, we noticed that the setting did not take effect in OVN. The configuration only applied successfully after we executed a manual script to propagate the setting directly to OVN [2]. Anyway such change is applicable only for exsisting networks, so it is far from perfect solution. Could you provide guidance on whether this behavior is due to incorrect documentation, an error in our configuration process, or an additional requirement needed to enable this feature? Any insights would be greatly appreciated. Thank you in advance for your support! /Jan Wasilewski **References:** [1] https://docs.openstack.org/neutron/latest/configuration/ml2-conf.html#ovn.f… [2] https://paste.openstack.org/show/b9xUcnG6GXmCdSbSReG0/

[openstack-ansible] issue
by Danish Khan 21 Jan '25

21 Jan '25

Dear All, Whenever I do any activity like Operating system upgrade of compute nodes or openstack major version update then the name of compute host gets updated. I have my compute node with name compute1,2,3.... but after the activity they sometimes become compute1.openstack.local or compute2.mgmt.local. Due to this I get duplicate resource providers. But only the latest provider works properly. and I had manually unset all the vm from old provider and added then into new provider. Is there a way I can avoid this? means I don't want my compute nodes to get renamed with domain. And is there a way I can unset a vm from all provider and heal them automatically instead adding them into new resource proivder? I tried below docs but the healing part is not working so I go with manual process for all vm which is too time consuming. https://docs.openstack.org/nova/yoga/admin/troubleshooting/orphaned-allocat… Regards, Danish Khan

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2025.1/R-10)
by Goutham Pacha Ravi 21 Jan '25

21 Jan '25

Hello Stackers, We're 10 weeks away from the 2025.1 coordinated "Epoxy" release [1]. Starting this week, there are several deadlines that project teams have adopted to ensure that code, specifications, and documentation changes are adequately peer-reviewed. As Slawek Kaplonski (slaweq) shared to this mailing list [2], the nomination period for the upcoming Technical Committee and Project Team Leads elections will begin on 2025-02-05 and remain open until 2025-02-19. Early nominations are highly encouraged in case you'll be unavailable during this period. In the last week, the OpenStack Technical Committee selected a community goal to migrate away from the eventlet library across its codebase [3]. As with many community goals, this will be a multi-release goal and needs contributors. Please join the #openstack-eventlet-removal IRC channel on OFTC to participate in the discussion. === Weekly Meeting === Dmitriy Rabotyagov (noonedeadpunk) chaired the TC's weekly IRC meeting on 2025-01-14 [4]. We discussed the maintenance of the "openstackdocstheme" Sphinx plugin and called out some early attempts to switch documentation to a stock theme that's more maintainable and sustainable. We also reviewed a proposal from Freezer project maintainers to remove the project team from the "inactive" teams list [5]. The TC also considered requesting an exception for Freezer to release within 2025.1. In this vein, we also highlighted the need for consistent criteria to move projects out of inactive status and better tooling for indicating project health and activity. The next meeting of the OpenStack Technical Committee is today, 2025-01-21. This meeting will be hosted via IRC on OFTC's #openstack-tc channel. Please find the meeting agenda on the wiki [6]. I hope you'll be able to join us there. === Governance Proposals === ==== Merged ==== - Propose to select the eventlet-removal community goal | https://review.opendev.org/c/openstack/governance/+/934936 - Rework the eventlet-removal goal proposal | https://review.opendev.org/c/openstack/governance/+/931254 - Add ansible-role-httpd repo to OSA-owned projects | https://review.opendev.org/c/openstack/governance/+/935694 ==== Open for Review ==== - Resolve to adhere to non-biased language | https://review.opendev.org/c/openstack/governance/+/934907 - Retire Freezer DR | https://review.opendev.org/c/openstack/governance/+/938183 - Retire qdrouterd role | https://review.opendev.org/c/openstack/governance/+/938193 - Remove Freezer from inactive state | https://review.opendev.org/c/openstack/governance/+/938938 - Reset the DPL model for oslo project | https://review.opendev.org/c/openstack/governance/+/939485 - Reset the DPL model for Release project | https://review.opendev.org/c/openstack/governance/+/939486 - Reset the DPL model for Requirement project | https://review.opendev.org/c/openstack/governance/+/939487 - Reset the DPL model for Watcher project | https://review.opendev.org/c/openstack/governance/+/939488 - Define 2025 upstream investment opportunities | https://review.opendev.org/c/openstack/governance/+/939507 === Upcoming Events === - 2025-01-28: OpenInfra Board Monthly Meeting: https://board.openinfra.org/ - 2025-02-01: FOSDEM 2025 (https://fosdem.org/2025/) OpenStack's 15th Birthday Celebration - 2025-02-05: Nominations open for 2025.2 TC/PTL Elections: https://governance.openstack.org/election/ - 2025-02-28: 2025.1 ("Epoxy") Feature Freeze and release milestone 3 [1] - 2025-03-06: SCALE 2025 + OpenInfra Days NA (https://www.socallinuxexpo.org/scale/22x) Thank you very much for reading!
