Vagrant version

$ vagrant -v
Vagrant 2.0.0

Host operating system

Mac OSX 10.11.6

Guest operating system

Ubuntu

Vagrantfile

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure(2) do |config|
  config.ssh.username = "root"

    docker.image = "nineseconds/docker-vagrant"

Expected behavior

Should be able to run two containers simultaneously.

Actual behavior

Port collision stops container from starting.

Steps to reproduce

1. Prepare two folders (a and b) with identical Vagrantfile
2. Run vagrant up in folder a
3. Run vagrant halt in folder a
4. Run vagrant up in folder b
5. Run vagrant up in folder a

When using Virtualbox as provider, running vagrant reload would solve the issue. With Docker, it just repeats the same error message.
