AMD Virtualization (AMD-V™) テクノロジー 

AMD Virtualization (AMD-V™) Technology is a set of hardware extensions to the x86 system architecture that allows you to better utilize your resources, which make your servers, clients, and datacenters more effective.  AMD-V™ simplifies existing software only virtualization solutions by reducing and sometimes eliminating the burden of trapping and emulating instructions executed within a guest operating system.

Powering ultrathin notebooks to blade servers, all AMD Athlon™, AMD Phenom™, AMD Phenom II, AMD Turion™ and AMD Opteron™ processors shipped by AMD will be able to use the AMD-V™ feature, and subsequently benefit from Windows® XP Mode in Windows® 7 

AMD Opteron™ processors with AMD Virtualization technology

HyperTransport™ Technology leverages the AMD Opteron™ processor with Direct Connect Architecture to provide fast and efficient memory handling, which is a must-have for memory intensive applications like virtualization. The combined effects of Direct Connect Architecture, an integrated memory controller, HyperTransport™ Technology, and AMD-V™ Technology with Rapid Virtualization Indexing help to streamline your datacenter and maximize your IT investment - reduce power consumption, support more users, more transactions, and more resource-intensive applications and achieve higher levels of efficiency and utilization in your virtual environment.

You need a server platform that can provide a robust and scalable environment for virtualization while maintaining power efficiency.

• Unmatched Memory Bandwidth and Scalability - Direct Connect Architecture allows more virtual machines (VMs) to be hosted per server and more users and transactions per virtual machines
• Rapid Virtualization Indexing (RVI) - Helps accelerate the performance of many virtualized applications by enabling hardware-based VM memory management.

• Enhanced Power Management - Manages power consumption so that you don’t waste energy during low utilization cycles
• Tagged TLB - Hardware features that facilitate efficient switching between VMs for better application responsiveness
• AMD-V™ Extended Migration - Hardware feature that helps virtualization software enable live migration of virtual machines between all available AMD Opteron™ processor generations.
