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.
