I've messed with virtual machines before, but only with XP (MS is pretty lenient with keys there). I have a legitimate Win8 Upgrade key for my desktop, and an Acer OEM key for my laptop. My plan is to install 8.1 inside VMWare Player (or Workstation) as the Guest OS, while my Host OS on both computers would be Linux. I'm curious as to what options I have available for activation though? Would using my legitimate keys not work and/or possibly flag them? Do I have to use "other" means of activation?
