Hi all, After a recent shift on the work focus, I'd like to thank you all for the efforts and support navigating the Telemetry boat around. I've been blessed working with this small but actively pushing for better community and truly wish someone finds the energy to keep the momentum going. Especially after Jadnesh moved on to next journey recently as well. Can't wait to see what's next ahead for the project. - Erno "jokke" Kuvaja

When applying Blazar filter to check if have available hosts, it is considering allocation ratio? File "/var/lib/kolla/venv/lib/python3.10/site-packages/blazar/plugins/instances/instance_plugin.py", line 310, in pickup_hosts ERROR oslo_messaging.rpc.server raise mgr_exceptions.NotEnoughHostsAvailable() ERROR oslo_messaging.rpc.server blazar.manager.exceptions.NotEnoughHostsAvailable: Not enough hosts available The host in blazar aggregate has 48 vcpus and 8.0 allocation ratio, 40 of this vcpus are consumed. Considering the allocation ratio, I must be able to create a lease with more than 8vCPU. Anyone can help? Regards.

[cinder] Bug report about cinder-migrate
by Gioh Kim (김기오) 10 Feb '25

10 Feb '25

Hi, I'd like to report a bug I found when doing cinder-migrate test. I really would appreciate it if somebody inform me if it is solved at the latest tag or not solved yet. I checked the latest tag 24.2.0 (https://github.com/openstack/cinder/releases/tag/24.2.0) but failed to find a bug patch looking relevant to my issue. I tested the volume migration of nvme volume (nvme-tcp volume with LVM) with "openstack volume migrate --host <servername@diskname#typename> <UUID>" command. The first migration worked well but the second migration failed always with "Skipping remove_export. No NVMe subsystem for volume: <uuid>" error. Below is what I found If the original volume UUID is '23c5155e' that exists in server-0002: = The first migration: server-0002 => server-0001 = - Create a new LVM volume with a different name UUID 'ed7a9c7b' => new nvme subsystem name is 'ed7a9c7b' (server-0001) - Set the UUID of new volume 'A' and set new attribute "os-vol-mig-status-attr:name_id | ed7a9c7b" - Remove/unmap the original volume on server-0002: unmap nvme subsystem name is '23c5155e' = The second migration server-0002 => server-0001 = - Create a new LVM volume with a different name UUID 'af60b1c7' on server-0001 - Try to unmap the nvme subsystem of 'af60b1c7' of server-0001 ==> it failed because there is no subsystem 'af60b1c7'. It should've unmap the subsystem "ed7a9c7b". I guess there is a problem at unmapping a subsystem of already migrated volume. It happens 100% whenever I migrated a volume twice. FYI, I am still using a ZED version. I hope it's solved at the latest tag. The HEAD commit of my repository is below: commit 51dbd1e8061012bee4baca8aa60bf16a459279f9 Merge: d854529c2 cb4682fb8 Author: Zuul <zuul(a)review.opendev.org> Date: Thu May 11 18:00:27 2023 +0000 Merge "Reject unsafe delete attachment calls" into stable/zed Gioh Kim (김기오) Cloud Storage Email gurugio(a)linecorp.com

[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
