RHEL 6上的Docker Cgroup安装失败

我试图了解一直在Centos + Vagrant上工作的东西,但不是我们的供应商RHEL(红帽企业Linux服务器版本6.5(圣地亚哥)).一个sudo服务码头重启这个:

Stopping docker:                                             [  OK  ]
Starting cgconfig service: Error: cannot mount cpuset to /cgroup/cpuset: Device or resource busy
/sbin/cgconfigparser; error loading /etc/cgconfig.conf: Cgroup mounting failed
Failed to parse /etc/cgconfig.conf                           [FAILED]

Starting docker:                                              [  OK  ]

该服务启动足够,但图像无法运行.我尝试时显示安装失败错误.启动日志也会发出一两个警告.关于核心警告,由于Epel应该解决这个问题,因此centos提供相同的并且没有问题:

WARNING: You are running linux kernel version 2.6.32-431.17.1.el6.x86_64, which might be unstable running docker. Please upgrade your kernel to 3.8.0.

任何人都有成功克服这个问题,或者我应该放弃并等待提供商更新到RHEL 7？
