Nova fails to start on a compute node. This may occur if the libvirtd process is running on the compute node before the deployment begins. The libvirtd process blocks nova_libvirt from starting. This issue applies to Oracle Linux compute nodes only, do not apply the workaround to Oracle VM Server compute nodes.

Workaround: Stop the libvirtd process on the compute node, and redeploy the container:

# systemctl stop libvirtd.service
