Yeah, it's a feature come with EPT. Thanks for reminder! Would update the patch soon. PS: The latest spec available at http://www.intel.com/products/processor/manuals/ It contains EPT and VPID and other new things on Nehalem. I would work on clearing up the code according to the latest spec soon (yeah, we also only got it for days...) -- regards Yang, Sheng
