虚拟机启动报错 Your VM has become “inaccessible.”

直接贴错误信息

Bringing machine 'default' up with 'virtualbox' provider...
Your VM has become "inaccessible." Unfortunately, this is a critical error
with VirtualBox that Vagrant can not cleanly recover from. Please open VirtualBox and clear out your inaccessible virtual machines or find a way to fix them.
                                                                                                                                                                                               

解决方法

C:\Users\Lqg\VirtualBox VMs\centos7_default_1526724395853_88884\

这个目录下没有 .vbox 文件，有个 .vbox-tmp 文件，把 .vbox-tmp 改成 .vbox就行。
