当我使用vagrant up命令时，出现此错误消息：

Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.
If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.
If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.
If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.
在Parallels上创建虚拟机，当我启动时，我到达登录页面。
我在Mac上使用PhpStorm并遵循本教程：http://www.pascallandau.com/blog/laravel-with-phpunit-on-vagrant-in-phpstorm/
如何解决问题？
