Public bug reported: I installed Vagrant (=2.0.2+dfsg-2ubuntu8) from apt on 18.04, and it appears the default provider is libvirt (vagrant-libvirt=0.0.43-2). I made a new Vagrantfile with "vagrant init" and changed the box in the Vagrantfile to "config.vm.box = "ubuntu/bionic64"" before running "vagrant up". This is what I got:
