Fail to start linux container after upgrading to docker 1.5

I used to use docker 1.3 and it worked well. There’re some problems after upgrading to docker 1.5. Is there something about my lxc? And I have tried apt-get purge lxc and apt-get install lxc to re-install it.

➜  ~  sudo docker version
Client version: 1.5.0
Client API version: 1.17
Go version (client): go1.4.1
Git commit (client): a8a31ef
OS/Arch (client): linux/amd64
Server version: 1.5.0
Server API version: 1.17
Go version (server): go1.4.1
Git commit (server): a8a31ef
➜  ~  sudo docker run -i -t ubuntu:14.10 /bin/bash
lxc-start: No such file or directory - failed to use 'proc sys'
lxc-start: failed to setup the mounts for 'b4f70ce8559154b65c80e48d3002ab804d9b00a952ae8efb7803d6251c865b16'
lxc-start: failed to setup the container
lxc-start: invalid sequence number 1. expected 2
lxc-start: failed to spawn 'b4f70ce8559154b65c80e48d3002ab804d9b00a952ae8efb7803d6251c865b16'
➜  ~  lxc-version
lxc version: 1.0.0.alpha1

And lxc seems work well to start.

➜  temp  sudo lxc-create -n test-container -t ubuntu
➜  temp  sudo lxc-ls --fancy
NAME            STATE    IPV4  IPV6  AUTOSTART  
----------------------------------------------
test-container  STOPPED  -     -     NO

Answer

Try switching from lxc to native exec drivers in docker. You can do this by adding –exec-driver=”native” to DOCKER_OPTS in config file ( /etc/default/docker). Native exec driver has now best support in docker and its used as default on most installations.
