Running Openshift in adb virtual-box
------------------------------------

1. Note adb virtual box already running etcd service which using port
7001 then stop those service (In my case, kubernetes/etcd service was 
running and due to that openshift/origin container was not able to run)
BZ #1271468

2. Start openshift origin container
