If virtualbox is a simulator, then it would simulate each CPU
instruction by a software function. It would be deaaad slow.

If it is an emulator, it uses the instructions by the CPU as-is. Much
better speed, but it's also don't have - can't no do. So if your Intel
CPU doesn't have 3dnow, no emulator can magically make it appear (as
they would need software simulation). I don't think vmware does that
either - e.g. it doesn't run 64bit guests on 32bit hosts (unless I'm way
off here).
