Web References on Intel Virtualization Technology
By David Ott (Intel)Posted March 30th 20090
Every so often people ask me for references on Intel virtualization technology. Below are a few helpful links that have served me well, whether it's getting broadly clued in on a technology like VT-d or looking up the particulars of MSR bit semantics. A good starting point for all things virtual ...
Step by Step Guide on How to Enable VT-d and Perform Direct Device Assignment
By Aamir Yunus (Intel)Posted February 24th 20094
This guide shows step by step instructions on how to "direct assign" Intel 85276 NIC to a virtual machine using Intel's VT-d technology. For this guide I am using the following hardware and software: Supermicro X8DTN+ Server with Intel Core i7 X5570 processors, American Megatrends BIOS R1.1 ...

i7 3930K C2 stepping confusion over EPT1
Hi, There is some confusion over if the i7 3930K C2 stepping can support EPT as part of its VT-x abilities. Some of the martieral on the Intel site say no while others have said that it does depending on the motherboard used. Could someone please clarify? Thanks, David.

Finding out if "Unrestricted Guest" supported at runtime2
Hi there, is there an option to find out at runtime (e.g. with means of CPUID or something else) if the "Unrestricted Guest" feature is supported on the CPU? In the developer manual I can only find which flags control the UG feature (i.e. "25.8. Unrestricted Guests" ff), but I don't see anywhere ...

Is it possible to use Intel NPT to do cross ISA memory translation?1
O.K., I know Intel virtualization techniques are used to help better performance for same ISA, i.e., x86, virtualization. But I am curious if we can use NPT to help us to do cross ISA memory translation. For example, I can run a ARM guest on x86 host by using QEMU, but the memory translation inside ...
