如果您正在使用包装层(如Kitchen CI)，并且正在运行32b主机，则必须抢先安装Vagrant盒子。它们的默认提供程序是二进制文件的opscode“家族”。

所以在厨房创建default-ubuntu-1204之前，请确保您使用:

vagrant box add default-ubuntu-1204 http://opscode-vm-bento.s3.amazonaws.com/vagrant/virtualbox/opscode_ubuntu-12.04-i386_chef-provisionerless.box

如果您的主机不支持字大小虚拟化，则使用32b映像

需要反复检查的一件事是，您的计算机BIOS中是否启用了硬件虚拟化。

我的问题是相同的超时字符串，但我只能在GUI中看到黑屏。

我刚刚安装的一台笔记本电脑一直显示同样的问题。经过几个小时的搜索，我终于找到了一个提示，看看BIOS是否启用了硬件虚拟化。

以下是我找到的帖子内容:

我发现仍然有一些用户遇到了这个问题。因此，我将尝试在下面总结一些可能的解决SSH超时问题的方法:

Make sure your firewall or antivirus is not blocking the program (which I doubt will happen often) Give your vagrant machine some time for timeouts to happen. If you dont have a very fast PC / Mac, the VM will take while to boot into an SSH ready state, so timeouts will happen. Therefore, first try to let vagrant timeout COMPLETELY before concluding that there is a fault. If vagrant times out completely then increase the timeout limit in the vagrant file to a few min and try again. If that still doesnt work, then try to clean boot your vagrant machine through the VirtualBox interface and enable the GUI of the machine beforehand. If the GUI doesn't show anything happening (ie. just blackscreen, no text) while it is booting, then your vagrant machine has got problems. Destroy the entire machine through the VB interface and reinstall. Delete the ubuntu image files in the Vagrant Images folder in the user folder and redownload and install. Do you even have an intel processor that supports 64bit hardware virtualisation? Google it. If you do, make sure there is no setting in your Bios disabling this feature. Disable hyper-v feature if you are running windows 7 or 8. Google how to disable. Make sure you are running through an SSH enabled client. Use Git bash. Download: http://git-scm.com/downloads Install a 32bit version of ubuntu like trusty32 or precise32. Just change the version in the vagrant file and reinstall vagrant in new directory. Make sure you are using the latest vagrant and virtualbox versions. Last resorts: Format your computer, reinstall windows and buy an intel core isomething processor.

希望这能有所帮助。

有这个问题超过一个星期，尝试了所有的解决方案，

1. giving SSH username and password
2. Enabling GUI interface
3. Updated Virtual Box and Vagrant

毫无效果。

终于从这个环节得到了解决方案

将谷歌公共DNS IP添加到您的Wifi设置中

在Network Preferences下面> Wifi > Advanced > DNS add IP Address 8.8.8.8

完美的工作。也许这可以帮助任何在Mac上有问题的人。 由于Skovmand

检查CPU在BIOS设置中的虚拟化是否已启用。

我是这样做的:

“vagrant up”启动虚拟机后，关闭虚拟机，在虚拟框中进入新的虚拟机设置。然后点击“网络”->“高级” 适配器类型:我从“英特尔PRO XXXXX”改为“PCNet-Fast”(或任何其他适配器除了英特尔PRO确实工作)
