vagrant启动失败解决办法

vagrant up
启动虚拟机报错

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.

解决方案

仔细看vagrant无法访问的提示：Please open VirtualBox and clear out your inaccessible virtual machines or find a way to fix them.看到这句话，于是打开virtualbox界面，virtualbox也提示该虚拟机无法启动，是因为C:\Users\denglj\VirtualBox VMs\vagrant_default_1411538218356_15372\vagrant_default_1411538218356_15372.vbox文件不存在。于是进入该文件的目录，发现并没有后缀为.vbox文件，而是多了一个.vbox-tmp的文件。

将后缀名改为.vbox，重新启动成功！
