I have downloaded the Windows Server 2016 iso from Microsoft for evaluation.
I then installed it via VirtualBox on my Macbook Pro running the latest Mac OS (High Sierra).
I downloaded Docker for Windows but when I try to load it, it either fails with an error saying it cannot write to database, or it fails because it says virtualization / Hyper-V has to be enabled in BIOS.
I have Hyper-V selected in the VirtualBox settings so that should work (and restarted the virtual machine).
However it still fails.
Is it possible to run Docker for Windows on a Windows Virtual Machine, all hosted on Mac OS?
