title: configure virtualbox vms to use proxy settings of host
body: <p>I have about 6 VMs for testing purpose in Virtualbox. We have a proxy at work and I do not have a proxy at home. so I switch the settings now and then to get internet inside the VMs. But there has to be a way that the VMs adapt the system settings of my host, or am I wrong? Google didn't help quite good yet. I just found an article about a Microsoft loop back interface, but nothing for Linux. By the way I use Linux just since October, so I am fairly new with this operation system</p>
  
  <p>Some system details:
  Host:</p>
  
  <ul>
  <li>arch-Linux with gnome shell and virtualbox 5.0.12</li>
  </ul>
  
  <p>Guests:</p>
  
  <ul>
  <li>Ubuntu, win7, win8, centos6 with nat bridge for internet purpose and host-only adapter for internal network</li>
  </ul>
  
  <p>Anybody experience in the matter who can help me?</p>
