docker:Error response from daemon: unable to remount sys readonly: unable to mount sys as readonly max retries reached

Docker在CentoOS6运行一个容器的时候出现下面的错误

[codesyntax lang="bash"]

[root@kvm ~]# docker run -i -t centos /bin/bash
2014/08/20 14:16:41 Error response from daemon: Cannot start container 2943ca118fe6082873601b110186242ed5d1524b9c2d9be213a64cf11d0dcdec: unable to remount sys readonly: unable to mount sys as readonly max retries reached

[/codesyntax]

碰到这个问题需要修改Docker的配置参数把/etc/sysconfig/docker文件中的other-args更改为：
[codesyntax lang="bash"]

other_args="--exec-driver=lxc --selinux-enabled"

[/codesyntax]

然后重新启动Docker服务
sudo /etc/init.d/docker restart
