title: Can I bring up the GUI for a Vagrant managed Virtual box while the box is running?
body: <p>I know that I can configure my Vagrantfile to boot my machine with a GUI according to <a href="http://docs.vagrantup.com/v2/virtualbox/configuration.html">http://docs.vagrantup.com/v2/virtualbox/configuration.html</a> with:</p>
  
  <pre><code>config.vm.provider "virtualbox" do |v|
    v.gui = true
  end
  </code></pre>
  
  <p>But if I've started a box headless, is there any way to bring up a GUI while the machine is running?  Virtualbox provides the small preview, so I suspect it is possible but I haven't found any documentation on how to do this.</p>
  
  <p>Edit:  Terry pointed out that I can <code>vagrant reload</code> after changing the setting above to get a gui, but that reboots the box.  I'm still hoping there's a easy way to enable the gui without a reboot.</p>
