[CEPH][DEPLOY ERROR] failed to create domain

Hi community :slight_smile:

I hope you find a solution to my issue.

I can’t create a virtual machine on my ceph cluster.

My configuration :

OpenNebula 6.2.0
KVM Host → Ubuntu 20.04

My ceph datastore :

Ceph system

Ceph image

My template

this is my error during the creation of new virtual machine

Driver Error
Wed Mar 16 14:58:47 2022: DEPLOY: error: Failed to create domain from /var/lib/one//datastores/131/371/deployment.0 error: internal error: process exited while connecting to monitor: 2022-03-16T14:58:50.547325Z qemu-kvm-one: -blockdev {“driver”:“rbd”,“pool”:“one”,“image”:“one-80-371-0”,“server”:[{“host”:“”,“port”:“3300”},{“host”:“”,“port”:“3300”}],“user”:“libvirt”,“auth-client-required”:[“cephx”,“none”],“key-secret”:“libvirt-2-storage-secret0”,“node-name”:“libvirt-2-storage”,“cache”:{“direct”:true,“no-flush”:false},“auto-read-only”:true,“discard”:“unmap”}: error connecting: Invalid argument Could not create domain from /var/lib/one//datastores/131/371/deployment.0 ExitCode: 255

I’ve no issue to contact my Ceph cluster since my KVM host with the oneadmin account :

oneadmin@cyln-kvm-01:/root$ rbd ls -p one --id libvirt

thank you for your help :slight_smile:

Kind regards

Hi, nobody to help me :frowning:


Can you create VMs on the same host using local storage ?


Thank for your answer.

I’ve no problem to create a virtual machine on my local storage and in my SAN storage with LVM.
