3.2.1 Intel® Virtualization Technology (Intel® VT) for Intel® 64 and IA-32 Intel®
Architecture (Intel® VT-x)
Intel® VT provides hardware assist to the virtualization software, reducing its size, cost, and
complexity. Special attention is also given to reduce the virtualization overheads occurring in
cache, I/O, and memory. Intel® VT-x specifications and functional descriptions are included in
the Intel® 64 and IA-32 Architectures Software Developer’s Manual.
3.2.2 Intel® Virtualization Technology for Directed I/O (Intel® VT-d)
A general requirement for I/O virtualization models is the ability to isolate and restrict device
accesses to the resources owned by the partition managing the device. Intel® VT for Directed
I/O provides VMM software with the following capabilities:
