Windows 8 desktop O/S will include Hyper-V support, however there seems to be some confusion about hardware requirements.

Hyper-V server has always required:

“Processor : x64 compatible processor with Intel VT or AMD-V technology enabled.
Hardware Data Execution Prevention (DEP), specifically Intel XD bit (execute disable bit) or AMD NX bit (no execute bit), must be available and enabled.”  (from

This hasn’t changed with the Hyper-v server version of Windows 8, but the desktop version of Hyper-V will require the processor also be SLAT compatible.  So, how do I know if my system will support Hyper-V?  Microsoft has a simple little command line tool called CoreInfo that will check for all requirements.

Simply open a command window with elevated privileges and run  coreinfo –v  to display the supported virtualization features.  An asterisk indicates supported and a dash means unsupported.


Intel64 Family  –  indicates 64 bit support
Hypervisor is present  –  shows if the Hypervisor role is currently enabled
Supports Intel hardware-assisted virtualization  – verifies Virtualization support
Supports Intel extended page tables (SLAT)  –  confirms SLAT compatibility

Another little utility worth mentioning is Securable by   This has been a standard for testing for Hyper-V compatibility, but so far does not include tests for SLAT support.  It does however have a specific DEP check.


I should also point out, if you plan to enable Remote FX support on a Hyper-V server (a server O/S), whether Server 2008 R2 or Windows Server 8, you will need a SLAT compatible processor.
