Laravel在Windows下搭建开发环境Homestead出现的一个大坑Timed out while waiting

$ cd ~/Homestead && vagrant up

然后出错。。。

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.

解决方案：

进入你的BIOS，然后将virtualization（CPU虚拟化）设置为enable即可

BIOS界面：Configuratio > Intel Virtual Technology > Enabled
