Should I Enable Virtualization?

If you are planning to install any virtualization application, you have to. Otherwise, it is better to disable it, because it has a small penalty, and your computer gets slower. You should activate hardware virtualization if you wish to use a virtual machine application like VirtualBox and have 64-bit virtual machines.

Is it bad to enable 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.

What will happen if I enable virtualization?
