vagrant up

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.

解決方案

baidu了一下解決辦法，有篇blog說直接刪除vagrant目錄下生成的.vagrant隱藏文件即可，該blog下的七八個comments都表示這個方法有效。不過這個方法並沒有解決我的問題。

再仔細看了看vagrant無法訪問的提示：Please open VirtualBox and clear out your inaccessible virtual machines or find a way to fix them.看到這句話，於是打開virtualbox界面，virtualbox也提示該虛擬機無法啟動，是因為C:\Users\denglj\VirtualBox VMs\vagrant_default_1411538218356_15372\vagrant_default_1411538218356_15372.vbox文件不存在。於是進入該文件的目錄，發現並沒有后綴為.vbox文件，而是多了一個.vbox-tmp的文件。

抱着試試的想法，簡單地將該文件后綴中的-tmp去掉，在執行vagrant up命令，成功了
