title: Sole Tenancy option mandatory for instance from image with OS on Cloud Engine
body: <p>When I create an Image from a vdi-file in Cloud Engine I have the option to choose if there is an operating system on the virtual disk or not (Data only). If I choose Windows 10 (x64) as the OS I need to configure a <em>Sole Tenancy</em> if I want to create an instance from the image.
  Why is this mandatory if a OS is present on the virtual disk?
  Thank You!</p>
