title: Connection lost after sudo reboot in vagrant
body: <p>I have started using Vagrant. I have some issues in restarting my VM.
  My Vagrantfile is:</p>
  
  <pre><code>Vagrant.configure("2") do |config
  config.vm.box = "precise32"
  config.vm.box_url = "http://files.vagrantup.com/precise32.box"
  </code></pre>
  
  <p>I open SSH by Vagrant SSH. Now if i give <code>"sudo reboot"</code> the connection to the VM is closed. I get the following:</p>
  
  <pre><code>vagrant@precise32:~$ sudo reboot
  vagrant@precise32:~$
  Broadcast message from vagrant@precise32
      (/dev/pts/0) at 9:43 ...
  
  The system is going down for reboot NOW!
  Connection to 127.0.0.1 closed by remote host.
  Connection to 127.0.0.1 closed.
  </code></pre>
  
  <p>How to solve this? Why is this happening?</p>
