Not that I would ever have got a Ryzen chip anyway, but this is concerning;

http://www.os2museum.com/wp/vme-broken-on-amd-ryzen/

Ryzen has buggy VME implementation; specifically, the INT instruction is known to misbehave in V86 mode with VME enabled when the given vector is redirected (i.e. it should use standard real-mode IVT and execute in V86 mode without faulting). The INT instruction simply doesn’t go where it’s supposed to go which leads to more or less immediate crashes or hangs

Now, don't get me wrong, most people don't emulate old OS' like Windows XP and the like, but I do quite a lot, mostly for old games.

The fact that these virtual machine capabilities are so fundamentally broken under Ryzen would be an immediate deal-breaker for me.

About the only game that comes to mind that would warrant a VM of XP is the MOH series.  Other than that, XP is probably the last thing I would want to emulate next to ME.  Seems to me this would only be a real bother for people who VM Linux, and I think AMD cares more about them than they do Windows VM users :p

It will affect any x86 based OS, though.

Ehh...to be honest the most I've ever done is run a copy of Windows 95 to play some of the educational games with which I grew up :)

They didn't work the first time, so why play them again?
