3.13 Intel

Virtualization Technology for Directed I/O (Intel

VT-d)

The Intel

3420 chipset provides hardware support for implementation of Intel

Virtualization

Technology with Directed I/O (Intel

VT-d). Intel VT-d Technology consists of technology

components that support the virtualization of platforms based on Intel

Architecture Processor.

Intel VT-d Technology enables multiple operating systems and applications to run in dependent

partitions. A partition behaves like a virtual machine (VM) and provides isolation and protection

across partitions. Each partition is allocated its own subset of host physical memory.

The Intel

Virtualization Technology is designed to support multiple software environments

sharing the same hardware resources. The Intel

Virtualization Technology can be enabled or

disabled in the BIOS setup. The default behavior is disabled.

Note: If the setup options are changed to enable or disable the Virtualization Technology setting

in the processor, the user must perform an AC power cycle for the changes to take effect.
