I think you missed the point, this is a i386 guest running on an amd64 host inside of a hypervisor, bottom line, your gona see advanced amd64 features in i386 running in such situations, and we should probably stop ignoreing this fact and embrace it as reality. Another words you are going to see i386 running on the 6 generation newer CPU that I dont have, and to say that this is unlikely is just a false statement. -- Rod Grimes rgrimes@freebsd.org
