Virtualization and emulation are not the same thing. You can have one without the other.
(Traditionally, virtualization precluded emulation: The hypervisor simply multiplexed hardware, and the guests got what looked like raw access to the real hardware, with no way of "seeing" the hypervisor at all. Very secure, very simple, and you could run a hypervisor as a guest with guests under it, recursively.)
