windows 10 `hosts` file can not resole a domain names that are in virtual machine

[luo kan]

I am using `Vagrant 2.0.0` on Windows 10 x64, VirtualBox is `5.1.26`.

I have installed centos 7 vagrant box , it is running correctly.  

`Vagrantfile` is like this：

```

    # -*- mode: ruby -*-

    # vi: set ft=ruby :

    

    Vagrant.configure("2") do |config|

      

      config.vm.box = "dev"

      config.vm.hostname = "vagrant-dev"

      config.vm.network "forwarded_port", guest: 80, host: 8080

      config.vm.network "private_network", ip: "192.168.33.3"

      config.vm.synced_folder "d:/vagrant_env/www/", "/var/www"

      

    end

```

I installed nginx in centos 7 vagrant box, and I can access nginx welcome page with ip `192.168.33.3`.   

I want to access it with domain name,so I configure `C:\Windows\System32\drivers\etc\hosts`

 file in windows:

```

192.168.33.3   test-example.vagrant   //add this line into `hosts` file of windows

```

and configure `/etc/nginx/conf.d/default.conf` file in centos 7:

```

    server {

        listen       80;

        server_name  test-example.vagrant;

        //...

    }

```

I try accessing `test-example.vagrant` on windows , but it does not work.   

   

what should I do?
