Comment 18 for bug 1621393

So I just tested again with the released image on Vagrant Atlas (https://atlas.hashicorp.com/ubuntu/boxes/xenial64/versions/20160914.0.0) and the image from Ubuntu Cloud Images (https://cloud-images.ubuntu.com/xenial/current/xenial-server-cloudimg-amd64-vagrant.box) and the bug still remains. So the `/etc/resolv.conf` file is empty and no hosts can be resolved and thus not reached.
