Start Docker Container

docker run -i -t ubuntu /bin/bash

When i run docker, i get following error on CentOS

FATA[0000] Error response from daemon: Cannot start container ef50fadd54129e442fcfec1ca955dc35814ca92091db5691d6b3ab7a7b4c902a: [8] System error: mountpoint for cgroup not found

This is fixed by installing libcgroup.

yum install libcgroup
service cgconfig start
