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). - Josh _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
