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?
