Virtualization Technology
Virtualization Technology is the name of the mutually incompatible virtualization technologies from Intel and AMD, previously known by their respective codenames "Silvervale" and "Pacifica". They allow a single machine to run multiple operating systems at once without incurring significant emulation costs.
Availability
Intel's software based emulation codenamed "Vanderpool" was officially launched at the Intel Developer Forum Spring 2005. It is available on all Pentium 4 6x2, Pentium D 9xx, Xeon 7xxx and Core Duo processors, though in the latter case it is sometimes disabled in the BIOS.
AMD's hardware based "Pacifica" emulation is planned to be available in both client and server processors from AMD in the first half of 2006.
Intel's core based "Silvervale", which stands to compete with AMD's "Pacifica", will not be out until late 2006.
Virtualization software
The following software is known to conditionally make use of virtualization technology features:
- Microsoft Virtual PC
- Microsoft Virtual Server — a future version (after Virtual Server 2005 R2) will support Intel VT and AMD Pacifica extensions.
- Parallels Workstation - lightweigh hypervisor with Intel VT-x support
- VMware — on Intel processors, VMware Workstation 5.5 requires Intel VT to execute 64-bit guests.[1]
- Xen — Xen 3.0 uses Intel VT to execute unmodified guest operating systems.
