Virtualization? Is my CPU supported? CPU-V

What is virtualization? Is my CPU supported?

 

Intel VT-x AMD-V

 

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.

A simple way of looking at virtualization is that you run a "computer in a computer." As a simple example of this, you can run a Nintendo emulator on a computer running Linux, Windows or Mac OS, allowing you to play games originally designed to run on a Nintendo Entertainment System (NES) on your computer. This is one example of virtualization - you're running a "virtual" NES on your (Intel x86) computer.

 

The advantages of virtualization technology:

1. To allow virtual machine to run guest 64-bit operating system.

2. Enabling Windows 7 XP mode. (Microsoft later released an update KB977206, to enable Windows Virtual PC and Windows XP Mode on computer without hardware virtualization support.)

 

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.

 

How to determine whether your processor supports virtualization technology:

1. Go to http://j.mp/lmcpuv and download LeoMoon CPU-V

2. Save and Run "LeoMoon CPU-V" on your desktop.

3. LeoMoon CPU-V will detect whether your hardware supports virtualization technology, and whether is enabled in your BIOS. In addition, LeoMoon CPU-V will also detect if Intel Trusted Execution (ITE) is enabled in BIOS. In most cases you need to turn ITE off.

LeoMoon CPU-V vs. SecurAble (older VT detection software, last updated 2007), SecurAble can only support 32-bit operating systems. On 64-bit operating system, SecurAble cannot detect whether virtualization is enabled in the BIOS.

Umm... Thats not "Virtualizing", thats "Emulating". Thats WHY they're are called Emulators.

 

Virtualizing=Running an OS inside an OS on the same CPU platform/architecture (i.e. x86 on x86)

 

Emulating= Running an OS/Game Console inside another OS/Game Console on a different CPU platform/architecture (i.e. PowerPC on x86, SNES on x86)

 

There's a big difference.
