如果你不想启用GUI，然后不得不禁用它，你也可以从Oracle安装扩展包:

然后把这个放在你的Vagrantfile中来启用VRDP:

vb.customize ["modifyvm", :id, "--vrde", "on"]

现在您可以使用RDP按需连接到您的盒子，而不需要运行SSH或一直打开GUI。

而不是ctrl-d-ing出虚拟框，因为我习惯做每当我ssh到任何东西，我相信流浪者更喜欢你进入另一个终端，并做一个:

流浪汉瘸腿

让盒子停下来。然后回到VB就没有问题了。

我在VirtualBox中运行vagrant/VirtualBox时得到了这个。我通过在主机上运行流浪机器来解决这个问题。

我有一个问题与现有的盒子(不确定什么改变)，但我可以通过SSH连接，即使流浪者盒子无法启动。碰巧我的SSH密钥以某种方式改变了。

从vagrant根文件夹中，我运行vagrant ssh-config，它告诉我密钥文件在哪里。我用puttygen打开它，它给了我一把新钥匙。

在我的Linux客户机上，我编辑了~/。Ssh /authorized_keys并将新的公钥放入其中。

现在一切都恢复正常了!

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。

我也遇到过同样的问题。我通过在BIOS设置中启用虚拟化来解决这个问题。
