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 :

this is my error during the creation of new virtual machine

Driver Error

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
one-78
one-80
one-80-371-0
one-81
one-test

thank you for your help :slight_smile:

Kind regards
