Should I enable hardware-assisted virtualization?

Often, virtualization technology is not required to emulate x86 or x86-64 instructions, albeit at the expense of speed. As a best practice, I would leave it explicitly disabled unless required. while it is true you should not enable VT unless you really use it, there is no more risk if the feature is on or not.
