遵循Getting Started说明，我这样做：
$ vagrant init hashicorp/precise64
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.
$ vagrant up

Vagrant 1.8.7
有什么想法吗？
我只需下载.dmg并安装即可从1.8.5（左右）升级到1.8.7。在运行之前我也删除了我的〜/ .vagrant.d。当我运行它时，1.8.7创建了自己的.vagrant.d。也许我以前的版本还剩下其他东西了吗？
我安装了虚拟机。
这也失败了：
$ vagrant up --provider virtualbox

他们status page说“所有系统都在运行”。
我尝试了一个旧盒子，一年前（之前一年？）工作过，现在已经坏了：
