The guest machine entered an invalid state while waiting for it
to boot. Valid states are 'starting, running'. The machine is in the
'poweroff' state. Please verify everything is configured
properly and try again.
If the provider you're using has a GUI that comes with it,
it is often helpful to open that and watch the machine, since the
GUI often has more helpful error messages than Vagrant can retrieve.
For example, if you're using VirtualBox, run `vagrant up` while the
VirtualBox GUI is open.
The primary issue for this error is that the provider you're using
is not properly configured. This is very rarely a Vagrant issue.
vargant up启动的时候遇到上述报错，无法启动虚拟机。
报错了咋办呢，按照提示去解决呗……

VirtualBox是Vagrant默认的Provider，提示信息是让打开Vagrant的GUI排查看看，为啥虚拟机一直处于‘关机状态’。原因八九成就是VirtualBox设置不正确。
那就打开VirtualBox呗，找到对应的虚拟机，在GUI界面上点启动看看。

点启动，看到上述警告，出了个警告，说没有找到USB 2.0控制器，以及2个解决问题的方法（据说USB 2.0组件不开源，所以必须从完全开源的VirtualBox主体中分离）：
- 安装‘Oracle VM VirtualBox Extension Pack’
- 在虚拟机设置中禁用USB 2.0 （只能用USB 1.1）
这就好办了，这里我使用的是第二种方法。找到

再回到终端，执行 vagrant up，发现ok了。
