Our DCs are made of hosts from 3 different models, so chances are that =
windows is
detecting a different CPU ID or something (that is a pity, as =

It may be true that we only encountered these issues on 2008 R2 =
guests.

Since then, we made no driver change, neither on hosts nor guests.

Further readings lead me to think that the kind of key IS the main =

No. I was told to be very prudent with using KMS servers, so not =
