You are right, it (maybe) just is a matter of efficiency of the emulated
parts of the VMM.

I wasn't aware how many unprivileged sensitive instructions the x86
instruction set has untill I looked it up (vs. a single one on m68000).

And thinking about it, some of the features introduced with AMD-V or
Intel VT-x (or only available in newer x86 cpus) like virtual page
tables have no meaning for RISC architectures (but for efficient m68k
virtualiziation they would be welcome).
