vagrant up 啟動時一直提示 remote connection disconnect retrying!

如題：
vagrant up 啟動時一直提示 remote connection disconnect retrying!

但是貌似有時候又可以啟動 不知道為什麼

remote connection disconnect retrying

我剛剛又重啟了下

The guest machine entered an invalid state while waiting for itto boot. Valid states are 'starting, running'. The machine is in the'unknown' state. Please verify everything is configuredproperly 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 theGUI often has more helpful error messages than Vagrant can retrieve.For example, if you're using VirtualBox, run `vagrant up` while theVirtualBox GUI is open.The primary issue for this error is that the provider you're usingis not properly configured. This is very rarely a Vagrant issue.

然後他提示出了這些語句，然後我再vagrant ssh 發現又能進去了。。。怎麼回事？
