Part of the generally accepted definition of virtualization is that the
majority of guest instructions execute directly on the real CPU with no
intervention by the VMM. QEMU + qvm86 does count as virtualization if
the system spends most of its time in user mode; QEMU on its own does
not (you run code that is very different to the original binary).
