[Bug 1749944] Re: Broken ubuntu-binary-nova-compute:pike No module named libvirt

[Randy]

The Pike version of Dockerfile.j2 adds these files to the libvirt
container.

        'ceph-common',
        'ebtables',
        'libvirt-clients',
        'libvirt-daemon-system',
        'openvswitch-switch',
        'pm-utils',
        'qemu',
        'qemu-block-extra'
You can view the file here: https://github.com/openstack/kolla/blob/stable/pike/docker/nova/nova-libvirt/Dockerfile.j2

The apt install of libvirt-daemon-system files to install the libvirt-
daemon.  This is using the Ubuntu Pike PPA.
