Intel Virtualization Technology (VT). Formerly known as Vanderpool, this technology enables a CPU to act as if you have several independent computers, in order to enable several operating systems to run at the same time on the same machine. In this tutorial we will explain everything you need to know about this technology. Intel’s virtualization technology is available in two versions: VT-x, for x86 processors; and VT-i, for Itanium (i.e., IA-64) processors. In this tutorial we will be covering the details of the VT-x technology.
VT-x is enabled in the bios if the bios and motherboard support it Example
No it will not hurt performance if it is enabled, most PC's have it disabled in the bios by default.

2it can be used by malicious code, so it is disabled by default for security reasons, every pc I bought has it disabled by default....serverfault.com/a/24691– MoabCommented Apr 13, 2016 at 16:39
