what cpu will work with hyper v

how do i verify if a cpu has the necessary requirements to run hyper v ?

Solution 1:

From the Hyper-V FAQ:

Q.  What are the system requirements for Hyper-V?

A.  In addition to the systems requirement for Windows Server 2008, 
    the two key requirements for the Hyper-V platform are the need 
    to ensure that the server is a 64-bit environment and supports 
    hardware-assisted virtualization (Intel VT or AMD-V) technology.

Solution 2:

You can use a tool called SecurAble which will tell you if your CPU supports Virtualisation Technologies, which is what you need to run Hyper-V. It will also tell you the number of bits supported by your CPU and if it supports DEP

Solution 3:

Your CPU must support Virtualization extensions. An easy way to check this is to search for your CPU model number in Google and look for a NewEgg.com link (this will find old models, unlike NewEgg's search). Check the "Virtualization Technology Support" field.

Be aware that this feature is typically disabled by default in the BIOS.
