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

关闭虚拟机内部的iptables防火墙

我是这样解决的:

我在我的Vagrantfile中启用了GUI界面(这是配置文件) 我可以在Gui中使用标准用户名vagrant和密码vagrant登录运行中的虚拟机 我关闭了虚拟机内部运行的iptables防火墙

这解决了我的问题，我发现，防火墙阻止了来自本地网络的所有ip，如192.168.x。X和10.x.x.x

添加/etc/iptables规则。D /199-allow-wan允许wan的所有连接:

ip46tables -A wan-input -j ACCEPT

(ip46tables是一个别名)在我的Vagrant例子Freifunk社区中看到这个提交

It used to help to switch to trusty32, but the situation now got worse again: I tried to use Homestead 2.0 and now I've got the Connection Timeout problem again, which would't usually be a problem, because switching to 32bit helped before. But now I can't just add a line like config.vm.box="ubuntu/trusty32" because we don't have a classic Homestead.yaml file anymore, the values in the new 2.0 Homestead.yaml file just seem to be inserted into the real one in the background and there ist no Vagrantfile available that I could manually edit ...

希望有人能帮忙……

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)

My solution turned out to be none of the above exactly. I'm running Ubuntu 14 as guest inside a Windows 7 host. I had been running this vagrant box fine, but I started it up again after not using it for a couple of months, and it kept coming up with the SSH connection timeout. It turned out that somehow the key pair didn't work - so I copied the Vagrant public key into Ubuntu according to the instructions on this page. But that wasn't all. I then discovered that the private key in my base box was different than the private key here. Putting this private key in as the vagrant_private_key file in C:\Users\your-user.vagrant.d\boxes\vagrant-box-name\nnnnnnnn\virtualbox after placing the public key into Ubuntu fixed the problem.

这是流浪者的新“特征”。看看这里: https://github.com/mitchellh/vagrant/issues/3329

他们将把“错误”改为“警告”。它只是告诉你机器还没有启动，它正在尝试连接…
