machine id isn't necessarily the important part. anticheat and vm detection check a lot of different heuristics incl hard to defend against things like timing attacks on particular cpu instructions. there's a handful of open source versions if you're curious
@brian To be honest, until and unless it becomes a problem for me, not really. KVM has the host CPU executing the VM instructions so timing on CPU instructions should product identical results. I have the VM setup as CPU and GPU pass through.
@Sheldan Yes I am referring to the game, back when I had tried on vmware it was still the main commercial one that I was playing, I have since moved to Insanity Flyff. One of those minor continuities in my life.
