[kayobe][a-universe-from-nothing] How does one restart controller0/compute0 after a reboot?
by Jordan Olin (OLINSolutions) 09 Feb '25

09 Feb '25

Hello, I’m following a-universe-from-nothing (2024.2) here <https://github.com/stackhpc/a-universe-from-nothing/blob/stable/2024.2/READ…>.in order to upskill on OpenStack deployment technologies. I’ve played a bit with the RDO-based installs, but a-u-f-n seemed closer to reality. My host VM is running Jammy (hostname: aufn-seed-jammy), with 64GB RAM and 100GB disk. I successfully made it through "Configure and deploy OpenStack to the control plane”, had running “seed”, “controller0”, “compute0” VMs, and was able to login to Horizon. I thought, “great! Let’s snapshot it all and keep going." So, I shutdown the host VM, aufn-seed-jammy (the one that is hosting “seed”, “controller0”, and “compute0”. I created a snapshot. I then restarted the host VM. The host VM (aufn-seed-jammy), and the seed VM started and I’m able to “ssh stack@seed” from the Host VM without problems. But… neither “controller0” nor “compute0” started up on their own. After sourcing Kayobe, from the host VM, I can “sudo virsh list —all” and see the following: (kayobe in ${KAYOBE_ENVIRONMENT:-base}) ubuntu@aufn-seed-jammy:~/deployment/src/kayobe-config/etc/kayobe$ sudo virsh list --all Id Name State ------------------------------ 1 seed running - compute0 shut off - controller0 shut off I then tried to manually start them: (kayobe in ${KAYOBE_ENVIRONMENT:-base}) ubuntu@aufn-seed-jammy:~/deployment/src/kayobe-config/etc/kayobe$ sudo virsh start controller0 error: Failed to start domain 'controller0' error: Cannot get interface MAC on 'p-contr0-0-tap': No such device I then ran an “ip a” to see what interfaces I have, but did not find one with that name.

[ovn][neutron] sriov port not able to get ip from DHCP
by Satish Patel 09 Feb '25

09 Feb '25

Folks, I have built a new openstack using kolla-ansible with 2024.1 with OVN plugin. So far everything is working good. Today I have added a new compute node with SRIOV port and it turns out vm is not able to obtain IP from DHCP. With the same subnet if I create general vm then it works and obtains IP but with sriov port it doesn't work. If I assign IP static on the vm interface then my VM is able to ping the outside world. I have deployed many clouds with OVN and SRIOV and never had an issue so I never dig into any kind of troubleshooting. This is the first time I have seen this issue. I have checked port mapping etc and all looks good. In SRIOV case what is the flow of DHCP? does physical interface send DHCP request on wire or DHCP request route via OVN br-int bridge? How will handle that DHCP request? Following two SRIOV port I have created but they are not able to obtain IP address via dhcp (ovn-nb-db)[root@os-chn-ctrl03 /]# ovn-nbctl --no-leader-only find Logical_Switch_Port type=external _uuid : a274df3b-6967-4f73-91ff-8f6eb46f70e0 addresses : ["fa:16:3e:03:55:44 10.74.2.35"] dhcpv4_options : 7829902c-5cdf-49cf-b478-7b683669c726 dhcpv6_options : [] dynamic_addresses : [] enabled : true external_ids : {"neutron:cidrs"="10.74.2.35/23", "neutron:device_id"="f4b91945-32f9-4961-a2cf-26b408218e35", "neutron:device_owner"="compute:sriov", "neutron:mtu"="", "neutron:network_name"=neutron-87131346-90d6-48ca-a045-214ff02ee9c0, "neutron:port_capabilities"="rx;tx;sg;tso;gso;gro;rxvlan;txvlan;rxhash;txudptnl", "neutron:port_name"=my-sriov-port, "neutron:project_id"="0c4956dce56a4503878007355850a04a", "neutron:revision_number"="32", "neutron:security_group_ids"="0bd505e8-d086-4d72-8e56-b913a8672f08", "neutron:subnet_pool_addr_scope4"="", "neutron:subnet_pool_addr_scope6"="", "neutron:vnic_type"=direct} ha_chassis_group : 0c41026b-3b01-485e-908a-523202aefcf9 mirror_rules : [] name : "0cbe012e-902a-4503-91a2-191b5f4acac5" options : {} parent_name : [] port_security : ["fa:16:3e:03:55:44 10.74.2.35"] tag : [] tag_request : [] type : external up : true _uuid : 1b245b6d-b720-41cd-a09c-79dc7eab3149 addresses : ["fa:16:3e:d8:4b:ab 10.74.2.181"] dhcpv4_options : 7829902c-5cdf-49cf-b478-7b683669c726 dhcpv6_options : [] dynamic_addresses : [] enabled : true external_ids : {"neutron:cidrs"="10.74.2.181/23", "neutron:device_id"="ac767d12-cff0-484e-b014-f3e42160cd8c", "neutron:device_owner"="compute:sriov", "neutron:mtu"="", "neutron:network_name"=neutron-87131346-90d6-48ca-a045-214ff02ee9c0, "neutron:port_capabilities"="rx;tx;sg;tso;gso;gro;rxvlan;txvlan;rxhash;txudptnl", "neutron:port_name"=my-sriov-p1, "neutron:project_id"="0c4956dce56a4503878007355850a04a", "neutron:revision_number"="5", "neutron:security_group_ids"="0bd505e8-d086-4d72-8e56-b913a8672f08", "neutron:subnet_pool_addr_scope4"="", "neutron:subnet_pool_addr_scope6"="", "neutron:vnic_type"=direct} ha_chassis_group : 0c41026b-3b01-485e-908a-523202aefcf9 mirror_rules : [] name : "bdf9261c-5cfc-4df1-9c11-c8ec26535eef" options : {} parent_name : [] port_security : ["fa:16:3e:d8:4b:ab 10.74.2.181"] tag : [] tag_request : [] type : external up : true

[nova] Wondering about dynamic overcommit scheduling
by Jacquet, Pierre 09 Feb '25

09 Feb '25

Hello, I am exploring the potential for resource consolidation from the initial placement perspective, specifically within the filter scheduler. From my research, I understand that OpenStack Watcher can addresses consolidation in a dynamic manner (monitoring resource usage and using live migration), while consolidation in nova seems to rely on a static overcommitment ratio, without accounting for real resource usage. Has dynamic overcommitment been considered for the initial placement phase? If not, I would like to propose implementing such a feature and would greatly appreciate any feedback or guidance from the community on this idea. Specifically, a custom filter could be interfaced with a monitoring stack to deploy servers as long as some thresholds are not exceeded Thank you for your time and input. Best regards, Pierre

[release] Release countdown for week R-7
by Thierry Carrez 07 Feb '25

07 Feb '25

Development Focus ----------------- We are entering the last weeks of the 2025.1 Epoxy development cycle. From now until the final release, we'll send a countdown email like this every week. It's probably a good time for teams to take stock of their library and client work that needs to be completed yet. The non-client library freeze is coming up, followed closely by the client lib freeze. Please plan accordingly to avoid any last minute rushes to get key functionality in. General Information ------------------- Next week is the Extra-AC freeze, in preparation for elections. All contributions to OpenStack are valuable, but some are not expressed as Gerrit code changes. Please list active contributors to your project team who do not have a code contribution this cycle, and therefore won't automatically be considered an Active Contributor and allowed to vote. This is done by adding extra-acs to https://opendev.org/openstack/governance/src/branch/master/reference/projec… before the Extra-AC freeze on February 13th. A quick reminder of the upcoming freeze dates. Those vary depending on deliverable type: * Oslo libraries are entering feature freeze next week, February 13th. * General libraries (except client libraries) need to have their last feature release before Non-client library freeze (February 20th). Their stable branches are cut early. * Client libraries (think python-*client libraries) need to have their last feature release before Client library freeze (February 27th) * Deliverables following a cycle-with-rc model (that would be most services) observe a Feature freeze on that same date, February 27th. Any feature addition beyond that date should be discussed on the mailing list and get PTL approval. After feature freeze, cycle-with-rc deliverables need to produce a first release candidate (and a stable branch) before RC1 deadline (March 14th) * Deliverables following cycle-with-intermediary model can release as necessary, but in all cases before Final RC deadline (March 28th) Finally, now is also a good time to start planning what highlights you want for your deliverables in the cycle highlights. The deadline to submit an initial version for those is set to one week after Feature freeze (March 6th). Background on cycle-highlights: http://lists.openstack.org/pipermail/openstack-dev/2017-December/125613.html Project Team Guide, Cycle-Highlights: https://docs.openstack.org/project-team-guide/release-management.html#cycle… jeremy [at] openstack.org/fungi on IRC is available if you need help selecting or writing your highlights. Upcoming Deadlines & Dates -------------------------- Extra-AC freeze: February 13th (R-7 week) Oslo feature freeze: February 13th (R-7 week) Non-client library freeze: February 20th (R-6 week) Client library freeze: February 27th (R-5 week) epoxy-3 milestone: February 27th (R-5 week) Cycle highlights deadline: March 6th (R-4 week) -- Thierry Carrez (ttx)

[openstack-ansible][masakari][yoga]pcs cluster not getting started
by Danish Khan 07 Feb '25

07 Feb '25

Dear All, I have upgraded my openstack cluster from wallaby to Yoga. And I am facing issue with masakari services. pacemaker service is running fine on all nodes but pacemaker_remote.service is not getting started on any of the nodes. And Masakari containers doesn't have any idea of it monitor nodes. I purged the masakari cluster and tried to deploy it again. Playbook is running successfully again and again but it is not setting up the cluster. Playbook is not installing corosync service on masakari containers and now pacemaker server is also not getting installed on masakari api containers. I idea to run masakari in a way that it can create the cluster and install required services on its own? I tried with below but that did not work:

[Monasca][Masakari][Requirements] Migrate of of oslosphinx
by Tony Breeds 06 Feb '25

06 Feb '25

Hello all, This is a heads up to let you know that the requirements team have approved 940215: Drop oslosphinx | https://review.opendev.org/c/openstack/requirements/+/940215 which will mean any changes to Monasca or Masakari that touch a requirements file will fail. The solution is to remove your dependency on oslosphinx, as many projects have done this I expect there is plenty of knowledge in git epos for what needs to be done. In the short term if your gate is blocked you can land a change that switches check-requirements to non-voting -- Yours Tony.

Hey Nova-ers That's a bit bittersweet but after running as a Nova PTL for 7 cycles, I preferred to leave this seat as I no longer have a lot of time for this. I'll continue to be around and I'll help our next PTL for sure :-) Thanks and see you at the PTG anyway :-) -Sylvain
