title: unable to access hostname in vagrant
body: <p>My vagrant file looks like this:  </p>
  
  <pre><code>Vagrant.configure(2) do |config|  
    config.vm.box = "chef/centos-7.0"  
  
  #cent71 will be the server  
    config.vm.define :cent71 do |cent71|  
      cent71.vm.hostname = "cent71.nv.server"  
      cent71.vm.network :private_network, ip: "192.168.70.101"  
    end  
  end
  </code></pre>
  
  <p>While I am able to access 192.168.70.101:8080 on my host machine's web browser, I am unable to access it via cent71.nv.server:8080<br>
  What should I change?</p>
