[Openstack] [nova][ceph] Libvirt Error when add ceph as nova backend

Hi,

your nova.conf [libvirt] section seems fine.

Can you paste the output of

ceph auth get client.nova

and does the keyring file exist in /etc/ceph/ (ceph.client.nova.keyring)?

Is the ceph network reachable by your openstack nodes?

Regards,
Eugen
