To take advantage of this you need KVM, which is a fork of qemu.
What's more these hardware instructions are in their early incarnations
and in many cases, given the horsepower of the machines featuring these
instructions, using traditional software-based virtualization
(VirtualBox, VMware, or qemu+kqemu) is smoother and faster.
