也许这是一个太简单的答案，以帮助许多人，但值得一试，如果你没有:做一个“流浪者暂停”，而不是“流浪者暂停”，然后重新启动VM与“流浪者up”。

我认为我的问题是由于一些“kworker”进程出现bug，并且在VM中不断超时，所以做硬重启似乎正确地重新加载进程，而保存和恢复只是在其破碎状态下恢复破碎的进程。

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:

http://www.oracle.com/technetwork/server-storage/virtualbox/downloads/index.html#extpack

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。

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。

我的运行正常，然后这个“警告:远程连接断开。一遍又一遍——大概20遍——直到连接上。基于以上的答案，我只是

vagrant destroy
vagrant up

一切都很好。我的很简单，但我把Vagrantfile压缩到config.vm.box = "ubuntu/trusty64"，它还在运行。这就是为什么毁灭然后重新开始似乎是最好的选择。鉴于这些流浪汉图像的无国籍性质，我不明白为什么在每个情况下都不会奏效。我刚刚开始研究这个问题，我可能会发现这不是真的。

我通过在/etc/fstab中添加一个新条目来测试我的vagrant VM中挂载的文件夹。后来我注销了，跑了个流浪汉，但当我跑了个流浪汉，我得到:

SSH auth method: private key
Warning: Remote connection disconnect. Retrying...

I read all these posts and tried all the ones that seemed relevant for my case (except for vagrant destroy, which would have certainly fixed my problem, but was a last resort in my case). The post by @Kiee gave me the idea to try to boot my VM directly from the VirtualBox GUI. During the boot process the VM halted itself and was asking me if I wanted to skip mounting the test folder that I had added earlier to /etc/fstab. (That's why vagrant couldn't boot the VM.) After answering 'NO' the VM booted no problem. I logged in, removed the naughty line from my fstab, and shutdown the VM.

在那之后，流浪汉就能很好地踢足球了。

外卖吗?如果突然间vagrant无法引导回您的VM，请尝试直接从提供商引导(在我的情况下是VirtualBox)。您的引导可能挂起了与SSH完全无关的东西。
