vmx!  +1

That's the flag for intel style cpu virtualization, VT-x, which shows
up IIRC only if the CPU has the capability *and* it's enabled in the
BIOS.  There are additional levels of virtualization, like VT-d, but
for a guest machine to perform close to (or exceed) performance on
bare metal it's VT-x (intel) or SVM (amd) that you need.

Thanks Andy
