这是我第二次发生这种情况：
我使用Vagrant创建了一个虚拟的Ubuntu机器,运行后：

sudo apt-get update
sudo apt-get升级

我懂了：

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.

当我调试ssh连接时,我看到了这个：

vagrant ssh -- -vvv
OpenSSH_6.9p1,LibreSSL 2.1.8
debug1: Reading configuration data ~/.ssh/config
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 20: Applying options for *
debug1: /etc/ssh/ssh_config line 102: Applying options for *
debug2: ssh_connect: needpriv 0
debug1: Connecting to 127.0.0.1 [127.0.0.1] port 2222.
debug1: Connection established.
debug1: key_load_public: No such file or directory
debug1: identity file ~/.vagrant/machines/default/virtualbox/private_key type -1
debug1: key_load_public: No such file or directory
debug1: identity file ~/.vagrant/machines/default/virtualbox/private_key-cert type -1
ssh_exchange_identification: Connection closed by remote host

这发生在Linux上,在Mac OS上也是如此.

也许有一个错误或我做错了什么.

解决方法

我在OSX 10.11.6和Vagrant 1.9.1上使用laravel / homestead 1.0.1框遇到了这个问题.

在Virtual Box VM设置中打开适配器上的“Cable Connected”.

虚拟盒GUI> VM设置>网络>适配器> ?电缆已连接

要永久修复此问题,请将其添加到vagrantfile的中间.

config.vm.provider’virtualbox’do | vb |??vb.customize [‘modifyvm’,：id,’ – cordablected1′,’on’]结束
