title: Docker inside VirtualBox
body: <p>Short: Is it possible to run docker container (microsoft/windowsservercore) inside VirtualBox (Windows 10 Enterprise). Host OS is Windows 10 Professional?</p>
  
  <p>Long: I managed to install and start docker inside VirtualBox (Win10Ent), but when I try to create container I get the following error:</p>
  
  <pre><code>docker.exe: Error response from daemon: container b9aef43f6b30853bc1f32fc663fdb5155a62f0dcb4be860c23a8b48fefae4d0a encountered an error during CreateContainer: failure in a Windows system call: No hypervisor is present on this system.
  </code></pre>
  
  <p><a href="https://stackoverflow.com/questions/39720254/can-i-run-docker-in-a-virtual-machine">Here</a> is similar question and the conclusion is that VirtualBox does not support nested virtualization, so Docker cannot be run inside of it.</p>
  
  <p>Having that said what is the option of VirtualBox machine under Settings -> System -> Acceleration -> Hardware Virtualization? 
  Can you explain what this Settings tab really means if VirtualBox does not support nested virtualization?</p>
