I'm trying this and although I know very little of OS (and I haven't
managed to boot up my first container yet because of other issues), I
have the docker entry in the web GUI "Admin -> System -> Hypervisors".

Looking at the nova.conf file, I see:

  compute_driver = novadocker.virt.docker.DockerDriver

It doesn't seem like I'm able to have multiple entries there. As in:

  compute_driver = novadocker.virt.docker.DockerDriver,libvirt

However, libvirt is defined in nova-compute.conf:

  [DEFAULT]
  compute_driver=libvirt.LibvirtDriver
  neutron_ovs_bridge=br-int
  [libvirt]
  virt_type=kvm
  vif_driver=nova.virt.libvirt.vif.LibvirtGenericVIFDriver
  use_virtio_for_bridges=true
  # This may be needed for
  #cpu_mode=host-passthrough

And I can't set:

  nova-compute.conf
    [docker]
    compute_driver = novadocker.virt.docker.DockerDriver,libvirt

  nova.conf
    compute_driver = docker

then I get:

What am I missing?
