There seem to be some inconsistency on ARK product reference site:
This document Compatibility with Intel® Virtualization Technology (Intel® VT) (http://www.intel.com/support/motherboards/desktop/sb/CS-030922.htm) specifies that chipset Z87 (DH82Z87) supports VT-d:
The following Intel® Desktop Boards support Intel VT with Directed I/O:
ChipsetDesktop Board H87, Q87, Z87 - DH87MC, DH87RL, DQ87PG, DZ87KLT-75K
and the chipset product page here http://ark.intel.com/products/75013/Intel-DH82Z87-PCH says:
"Intel® Virtualization Technology for Directed I/O (VT-d) ‡ No".
Please confirm if this chipset supports this virtualization feature.
Thanks,
