In some cases it may be desirable to run the libvirt daemon on the host. For example, when mixing host and container OS distributions or versions. This change makes it possible to disable the nova_libvirt container, by setting enable_nova_libvirt_container to false. The default values of some Docker mounts and other paths have been updated to point to default host directories rather than Docker volumes when using a host libvirt daemon. This change does not handle migration of existing systems from using a nova_libvirt container to libvirt on the host.

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.
