In Ussuri, nova stopped using separate Ceph keys for the volumes and vms pools by default. Instead, we set ceph_nova_keyring to the value of ceph_cinder_keyring by default, which is ceph.client.cinder.keyring. This is in line with the Ceph OpenStack integration guide [1]. However, the user used by nova to access the vms pool (ceph_nova_user) defaults to nova, meaning that nova will still try to use a ceph.client.nova.keyring, which probably does not exist. We did not see this issue in CI, because we set ceph_nova_user to cinder. This change fixes the issue by setting ceph_nova_user to the value of ceph_cinder_user by default, which is cinder.

Kolla Ansible
The Kolla Ansible is a deliverable project separated from Kolla project.
Kolla Ansible deploys OpenStack services and infrastructure components in Docker containers.
Kolla's mission statement is:
To provide production-ready containers and deployment tools for operating
OpenStack clouds.Kolla is highly opinionated out of the box, but allows for complete customization. This permits operators with little experience to deploy OpenStack quickly and as experience grows modify the OpenStack configuration to suit the operator's exact requirements.
Getting Started
Learn about Kolla Ansible by reading the documentation online Kolla Ansible.
