Intel Virtualization Technology (VT-x) allows one hardware platform to function as multiple virtual" platforms. It offers enhanced manageability by limiting downtime & maintaining productivity by isolating computing activities into separate partitions. Intel Virtualization Technology for Directed I/O (VT-d) continues from the existing support for IA-32 (VT-x) & Itanium processor (VT-i) virtualization adding new support for I/O-device virtualization. Intel VT-d can help end users improve security & reliability of the systems & also improve performance of I/O devices in virtualized environments. Intel 64 architecture delivers 64-bit computing on server, workstation, desktop & mobile platforms when combined with supporting software. Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual & physical memory. Idle States are...
