Bug description:
  [Summary]
When stop container and restart container via docker cli (docker stop xx / docker start xx) on compute node, ip of this container will be lost.   for detail pls refer following logs.  
  [Topo]
  Unbuntu Kilo 14.04 OS , Kilo docker setup , 1 controller ,2 network node,6 computenode

  [Reproduceable or not]
  Can be reproduced, 

  [Recreate Steps]

Meanwhile, we also tried these two ways to check if the container can get ip or not,
a, launch a new container, can get ip successfully; 
b, stop and re-start via nova stop xxx / nova start xxx , container can get ip successfully. 


# Steps:
1, Build up a openstack & docker setup based on Ubuntu 14.04 trusty; 
2, 1 controller, 2 network node and 7 computer node ; 
3, Launch docker containers;
