我检查了https://openvz.org/Docker_inside_CT
在我的 VPS 内核版本是 2.6.32-042stab120.11
托管确认他们中的一些客户正在使用安装了 docker 的 Openvz。所以我应该能够运行 Docker。
我试图为我的问题找到解决方案，但没有任何成功。
我可以安装 CentOS；debian7,8；Ubuntu 14,16。我在 debian 8 和 ubuntu 16.04 上试过，我收到同样的问题在安装过程中我收到错误：
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.
invoke-rc.d: initscript docker, action "start" failed.

我不知道为什么 docker 版本没有让我恢复服务器版本以及如何强制 docker 在这台机器上工作。
如果我安装 docker-engine 1.9.1 我得到
