Check CPU virtualization support. CPU-V the right tool!

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 LeoMoon Studios - New Dimension Order! - Shop - Application - LeoMoon CPU-V 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.

 

Do you know if it is disabled in BIOS will it give some performance?

 

Avoid, avoid, avoid!
The author of this tool seems to be a horrible astroturfer, and has even vandalized/modified the Vikipedia page on virtualization to change the link from Microsoft's tool at Download details: Microsoft® Hardware-Assisted Virtualization Detection Tool to his own product.

Mods, can we have this spam thread removed?

 

I just want to share with people here about VT. I know there is lot of people struggle with whether VT is enable in vaio laptop.

 

Virtualisation is fairly painless. The biggest problem users face is that their flavour of Windows doesn't support it. Professional or better.

 

For clarification, Linux qualifies as "or better".

 

This is what I want to know too.

Otherwise, why not just always have it on? Why is there an option to turn it off?

 

Run a few benchmarks and see.

Personally, I think the option to turn it off is for troubleshooting in case hardware assisted virtualization causes problems in the virtual machine. With the option turned off in the BIOS, the VM will have to use software mode which is less efficient, but potentially more stable.

Since most people use the virtual mode for running legacy apps, the performance hit is not as much of a big deal.

 

Hehe, I'm too lazy to do that.

That would make sense, but VM applications allow you to choose the emulation mode. So you can always turn off hardware VM-x virtualization in software, no need to force it off in BIOS.

 

While we're on the topic of virtualization, is virtualization what allows xp mode for running older applications?

Becuase I've run across a few older applications that I cannot run on my vpcz1190x the first one that someone could quickly try out is skyroads: SkyRoads <---that's the official website to the old dos game.

I cannot get this game to run on my vpcz, and i'm getting the same error when trying to run Rosetta Stone. Here is the error:

"The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher."

I believe it has something to do with virtualization so I figured this would be considered on topic. Thanks for any help or suggestions.
