Hello everyone, After upgrading to Antelope i´m getting following errors when creating new volume-backed instance. Volumes are stored in a ceph pool. - nova: 27.4.0 - libvirt: 8.0.0 - qemu: 6.2.0 - Operating system: Ubuntu 22.04 ``` ERROR nova.virt.libvirt.driver [instance: f8fa30f3-3dc8-43bd-bc29-8ed23b15b1f2] Failed to start libvirt guest: libvirt.libvirtError: internal error: process exited while connecting to monitor: 2025-03-04T15:15:34.416946Z qemu-system-x86_64: -blockdev {"driver":"rbd","pool":"cinder","image":"volume-6dfe3084-ef9d-4107-8b69-b0036fefbed0","server":[{"host":"1.2.3.4","port":"1234"},{"host":"1.2.3.5","port":"1234"},{"host":"1.2.3.6","port":"1234"}],"user":"cinder","auth-client-required":["cephx","none"],"key-secret":"libvirt-1-storage-auth-secret0","node-name":"libvirt-1-storage","cache":{"direct":false,"no-flush":false},"auto-read-only":true,"discard":"unmap"}: error connecting: Permission denied libvirtd[50229]: internal error: process exited while connecting to monitor: 2025-03-04T15:15:34.416946Z qemu-system-x86_64: -blockdev {"driver":"rbd","pool":"cinder","image":"volume-6dfe3084-ef9d-4107-8b69-b0036fefbed0","server":[{"host":"1.2.3.4","port":"1234"},{"host":"1.2.3.5","port":"1234"},{"host":"1.2.3.6","port":"1234"}],"user":"cinder","auth-client-required":["cephx","none"],"key-secret":"libvirt-1-storage-auth-secret0","node-name":"libvirt-1-storage","cache":{"direct":false,"no-flush":false},"auto-read-only":true,"discard":"unmap"}: error connecting: Permission denied libvirtd[50229]: internal error: qemu unexpectedly closed the monitor: 2025-03-04T15:15:34.416946Z qemu-system-x86_64: -blockdev {"driver":"rbd","pool":"cinder","image":"volume-6dfe3084-ef9d-4107-8b69-b0036fefbed0","server":[{"host":"1.2.3.4","port":"1234"},{"host":"1.2.3.5","port":"1234"},{"host":"1.2.3.6","port":"1234"}],"user":"cinder","auth-client-required":["cephx","none"],"key-secret":"libvirt-1-storage-auth-secret0","node-name":"libvirt-1-storage","cache":{"direct":false,"no-flush":false},"auto-read-only":true,"discard":"unmap"}: error connecting: Permission denied os-cmt7 libvirtd[50229]: Unable to read from monitor: Connection reset by peer ``` Any fixes/tips? From The compute node accessing the ceph pool using `rbd` client, there are no permission errors. Are this errors related to qemu monitor?

[neutron] LXB Removal and OVN migration
by Ricardo Cano 04 Mar '25

04 Mar '25

Hello openstack-discuss, With the removal of the linuxbridge mechanism driver, has anyone successfully completed an in-place migrationfrom LinuxBridge to OVN? I did come across this https://www.jimmdenton.com/migrating-lxb-to-ovn/ and that looks good as a one-shoit while biting the bullet and taking a full outage. However, I was wondering if it was possible to run lxb and ovn side-by-side and cut them over, say one network at a time. This particular deployment was stood up using openstack-ansible back in the rocky days (now running antelope) and it appears that openstack ansible's default was lxb up until Zed. Any suggestions or recommendations on the best path forward? Also, will the dynamic routing agent work with ovn?

Dear Mentors, I have good experience in building openstack in multiple environments bare-metal, kolla-ansible and helm project for minimal deployment to good HA clusters. Now, I'm looking to get into code level and contribute to open-infra foundation. I'm not a someone beginner to coding, I have done programming in a good amount and hold a knowledge of paradigm and principles. Here's my github: https://github.com/jamesii-b I'm looking for mentor who can guide me what to do as a Contribution.. Even deploying first openstack is overwhelming on its own, Coding is more. Please have me. Trust me, I'll have utmost respect to your time and energy and get most of it. Knowledge I have: HPC, Openstack Deployment, Network & System, Parallel Programming, Python, Rust.

Installation guide: service_user_token clarification
by Eugen Block 03 Mar '25

03 Mar '25

Hi *, to me it's still a bit unclear, what exactly is required to properly set up service user tokens. The Yoga release notes point to the nova configuration guide [0], which only briefly describes the concept. But looking at the latest installation guide [1], there's also only a very short section with a link to the config page. But there's no mention of a service role that has to be created. If this is the default since Yoga, shouldn't the installation guides cover the entire process, including creating all necessary roles or the [keystone_authtoken] section that should probably contain "service_token_roles = service"? I currently find it quite confusing. Thanks! Eugen [0] https://docs.openstack.org/nova/latest/admin/configuration/service-user-tok… [1] https://docs.openstack.org/nova/2024.2/install/controller-install-ubuntu.ht…
