title: virtualbox missing add "host-only network" option
body: <p>Running Virtual Box in:
  Host Mac High Sierra
  Guess Windows 7</p>
  
  <p>I am trying to connect from the Host to guess following several tutorials which involve create a "<strong>host-only networks</strong>" on the Virtual Box</p>
  
  <p>However, I cannot see the option to add  "Host-only networks" in the settings, only NAT networks. See attached picture</p>
  
  <p>I would appreciate if anyone could help me</p>
