CPU-V can detect whether your hardware supports virtualization technology, and whether is enabled in your BIOS. In addition, CPU-V will also detect if Intel Trusted Execution (ITE) is enabled in BIOS. In most cases you need to turn ITE off.
In computing, virtualization is a broad term that usually refers to the abstraction of resources on a computer. Usually this is accomplished using either a virtual machine or an operating system that has tools to enable virtual environments to run inside it.
The advantages of virtualization technology:
Enabling virtualization will enhance performance of applications inside virtual machine. For example, in Windows 7 XP mode, or in any VMware virtual machine will experience faster performance in guest OS.
