@boucher This PR fixes the network endpoint problem when restoring a container. The endpoint should be reused by a checkpointed container so that the network resources (e.g., iptable rule) will not be changed after restoring. Please review if it fits into your branch. Thanks. |

If I run this code, and then checkpoint and restore a container, it still can't access the network. I believe this is related to the issue I filed here: moby#14027 (To test, I just exec'd into the restored container and tried ping'ing google.com) Are you actually able to use the network after a restore? |

@boucher Update the patch for 1.8.0-dev, but the problem you described still exists. I will look into this issue these days. |
