cannot boot container with Ubuntu liberty installation

[Hui Kang]

Hi
I am new to nova docker. I have an existing OpenStack deployment with Ubuntu package. Following is the version information.
----------------------
ii nova-common 2:12.0.1-0ubuntu1~cloud0 all OpenStack Compute - common files
ii nova-compute 2:12.0.1-0ubuntu1~cloud0 all OpenStack Compute - compute node base
ii nova-compute-kvm 2:12.0.1-0ubuntu1~cloud0 all OpenStack Compute - compute node (KVM)
ii nova-compute-libvirt 2:12.0.1-0ubuntu1~cloud0 all OpenStack Compute - compute node libvirt support
ii python-nova 2:12.0.1-0ubuntu1~cloud0 all OpenStack Compute Python libraries
ii python-novaclient 2:2.30.1-1~cloud0 all client library for OpenStack Compute API

----------------------

Then I installed nova-docker from the master branch of nova-docker's github repository. After installation, I can upload a row docker image successful. However, it failed to boot a docker container. The error message at the nova-compute is

Is there any bug in the nova-docker code in the git repo. Thanks in advance. - Hui

2:12.0.1-0ubuntu1~cloud0 sounds like liberty. Are you using the nova-docker from stable/liberty branch?
