Comment 21 for bug 1569237

I can ssh into the box using the private key, or vagrant ssh. But if I want to just ssh in normally, I have to use a password. And I have no idea what the password for "ubuntu" would be. It would be much better to use the normal vagrant/vagrant user.

VBoxManage --version
5.1.0r108711

vagrant --version
Vagrant 1.8.4

xenial.vm.box = "ubuntu/xenial64"
xenial.vm.box_url = "https://cloud-images.ubuntu.com/xenial/current/xenial-server-cloudimg-amd64-vagrant.box"
