Kilo Docker: Hypervisor Type Not Defined

[Nastooh]

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:
