我正在以root用户身份登录的Mac上使用Ubuntu在流浪汉虚拟盒子中运行docker，我正试图从devicemapper切换到overlay，但我收到一条错误消息：
root@vagrant-ubuntu-trusty-64:/# service docker stop
docker stop/waiting
root@vagrant-ubuntu-trusty-64:/# rm -rf /var/lib/docker
root@vagrant-ubuntu-trusty-64:/# docker daemon -s overlay
Command "daemon" is deprecated, and will be removed in Docker 1.16. Please run `dockerd` directly.
INFO[0000] libcontainerd: new containerd process, pid: 6788

我试过以下说明：
http://www.projectatomic.io/blog/2015/06/notes-on-fedora-centos-and-docker-storage-drivers/ Unable to start Docker Service in Ubuntu 16.04
但他们都不适合我 .
当我尝试遵循以下文档时：
https://docs.docker.com/engine/userguide/storagedriver/overlayfs-driver/
我在第2步遇到困难，因为grep没有从lsmod返回任何'overlay'：
root@vagrant-ubuntu-trusty-64:/# uname -r
3.13.0-107-generic
root@vagrant-ubuntu-trusty-64:/# lsmod | grep overlay
root@vagrant-ubuntu-trusty-64:/#
root@vagrant-ubuntu-trusty-64:/# dockerd --storage-driver=overlay

我该如何解决这个问题？

你正在运行内核3.13，所以没有骰子 . 我的建议是备份你的虚拟机并尝试将内核升级到更新的版本（我有14.04并且有更新的内核可用，但尚未测试它们的工作情况）或将你的Ubuntu VM升级到16.04
