I’ve seen in other threads that this problem can be worked around by choosing an older CPU model to pass to the Windows guest (e.g., Core2Duo). However regardless of which CPU model I choose it always gets passed through as a Ryzen 7 1700.
I followed this tutorial to get GPU pass through working, but something in Gray Wolf’s process seems to enable CPU pass through and disable any ‘downgrades’.
It’s academic for the time being, since I can defer the upgrade for a year, but I would like to get this sorted out before my time runs out.
