Devstack安装错误（赛普拉斯版本，使用Vagrant和Virtual Box的Ubuntu 14）

Question

我相信这里使用的开发环境非常普遍。我检查了nfsd，如下所示：

ps aux | grep nfsd

输出结果显示nfsd正在运行。

但是，使用vagrant up命令，我收到以下错误消息。 VM管理器还显示一些错误消息。 vagrant reload命令也没有帮助。

(many things happens up to this point smoothly...)
default: 8110 => 8110 (adapter 1)
default: 50070 => 50070 (adapter 1)
default: 8088 => 8088 (adapter 1)
default: 22 => 2222 (adapter 1)
==> default: Running 'pre-boot' VM customizations...
==> default: Booting VM...
==> default: Waiting for machine to boot. This may take a few minutes...

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.

如果你能引导我去哪里研究，我真的很感激。 祝福
