  Invalid

Bug description:
  On a multinode setup, based on Ubuntu14.04, with nova version, below
   # dpkg -l | grep nova
  ii  nova-common                         1:2015.1.0-0ubuntu1~cloud0            all          OpenStack Compute - common files
  ii  nova-compute                        1:2015.1.0-0ubuntu1~cloud0            all          OpenStack Compute - compute node base
  ii  nova-compute-kvm                    1:2015.1.0-0ubuntu1~cloud0            all          OpenStack Compute - compute node (KVM)
  ii  nova-compute-libvirt                1:2015.1.0-0ubuntu1~cloud0            all          OpenStack Compute - compute node libvirt support
  ii  python-nova                         1:2015.1.0-0ubuntu1~cloud0            all          OpenStack Compute Python libraries
  ii  python-novaclient                   1:2.22.0-0ubuntu1~cloud0              all          client library for OpenStack Compute API
  ,  did the following:
  1- Followed https://wiki.openstack.org/wiki/Docker procedure
  2- Added nova to libvirtd group, to avoid /var/run/libvirt/libvirt-sock access problem
  3- Updated nova-compute.conf to include compute_driver=novadocker.virt.docker.DockerDriver and virt_type=docker

  Upon starting a new docker instance, got the following error:

  Looking at /usr/lib/python2.7/dist-packages/nova/compute/hv_type.py, noted that DOCKER definition is missing. Updated the file to include the following:
  ...
  ZVM = "zvm"
  DOCKER = "docker"
  ALL = (
      BAREMETAL,
      BHYVE,
  ....
   ZVM,
      DOCKER
  )

  With this update, I am able to instantiate rastasheep/ubuntu-sshd:14.04 image:
