I've always read on here that you cannot run a Windows Virtual Machine on macOS on our Bare Metal Threadrippers.
As I was on day release from hospital today, I updated my machine to the latest OC release (0.7.0) and the latest BS Beta (11.5 beta 3). Whilst in hospital I had fixed a friends laptop that was continually crashing be wiping it and loading the latest Windows, Win10_21H1. As I had the ISO on a USB drive I decided to try a VM on the Threadripper, thinking it wouldn't work.
My copy of VM Fusion was very old, V6, so I downloaded the latest VirtualBox to play with. I know it isn't the best VM software but it is free.
It was with great surprise then that a Windows VM was up and running in a matter of minutes. No having to try and patch anything or anything else. I have always had SVM enabled in my BIOS setup so I didn't even have to change anything in there either.
So it works. I haven't tried passing through the RX 6900 XT or RX 6800 XT through to it yet, I was just astonished that it worked straight away.
