Hardware-Assisted Virtualization Technology

Improving the fundamental flexibility and robustness of traditional software-based virtualization solutions

Hardware-assisted virtualization

Hardware-based Intel® Virtualization Technology (Intel® VT)1 improves the fundamental flexibility and robustness of traditional software-based virtualization solutions by accelerating key functions of the virtualized platform. This efficiency offers benefits to the IT, embedded developer, and intelligent systems communities, including:

  • Speeding up the transfer of platform control between the guest operating systems (OSs) and the virtual machine manager (VMM)/hypervisor
  • Enabling the VMM to uniquely assign I/O devices to guest OSs
  • Optimizing the network for virtualization with adapter-based acceleration

Many embedded developers are using virtualization to run multiple operating systems on their devices, enabling them to:

  • Simplify the porting of legacy applications onto new platforms
  • Increase the determination of time-critical functions
  • Improve the security and stability of safety-critical code

How it works

Intel VT performs various virtualization tasks in hardware, like memory address translation, which reduces the overhead and footprint of virtualization software and improves its performance.

In fact, Intel developed a complete set of hardware based virtualization features designed to improve performance and security for virtualized applications. 4th generation Intel® Core™ vPro™ processors include:

Server virtualization
Get enhanced server virtualization performance in the data center using platforms based on Intel® Xeon® processors with Intel VT, and achieve faster VM boot times with Intel® Virtualization Technology FlexPriority and more flexible live migrations with Intel® Virtualization Technology FlexMigration (Intel® VT FlexMigration).

The Intel® Xeon® processor E5 family enables superior virtualization performance and a flexible, efficient, and secure data center that is fully equipped for the cloud.

The Intel® Xeon® processor 6500 series delivers intelligent and scalable performance optimized for efficient data center virtualization.

The Intel® Xeon® processor E7 family features flexible virtualization that automatically adapts to the diverse needs of a virtualized environment with built-in hardware assists.

Desktop virtualization
Intelligent Desktop Virtualization, using PCs powered by 4th generation Intel Core vPro processors with Intel VT, can improve IT security, management, and control, while reducing complexity. Intelligent Desktop Virtualization can also improve application performance and responsiveness and increase the efficiency of data center resources.

In addition, PCs based on 4th generation Intel Core vPro processors include support for hardware-based security and manageability to improve the management and security of remote desktops and laptops.

Industrial systems

Many industrial systems, like programmable logic controllers and motion controllers, require a combination of low-latency, deterministic response and full-featured user interfaces. Virtualization enables systems to simultaneously run real-time and general-purpose operating systems, each on dedicated processor cores of an Intel® multi-core processor. This configuration can increase the speed and determinism of time-critical applications, because they operate unencumbered by non-real-time tasks that otherwise compete for CPU resources. Furthermore, virtualization enables equipment manufacturers to combine functions running on multiple boards onto one board, which lowers platform cost and reduces system size.

Medical devices

Securing applications and patient data is essential for medical diagnostic equipment. Applications requiring a higher level of security can be isolated using Intel VT, which protects their memory space in hardware and helps prevent attacks from malicious software. As such, software running in a secure partition only has access to its own code and data regions, unable to page outside its memory boundary because the hardware precludes unauthorized access.

Produkt- und Leistungsinformationen


1. Für die Intel® Virtualisierungstechnik (Intel® VT) ist ein Computersystem erforderlich, dessen Intel® Prozessor(en), BIOS und Virtual-Machine-Monitor (VMM) für diese Technik geeignet sind. Bei einigen Anwendungen gilt diese Forderung zusätzlich für bestimmte Plattformsoftware. Die Funktions- und Leistungseigenschaften sowie andere Merkmale unterscheiden sich je nach Hardware- und Softwarekonfiguration, wobei ein BIOS-Update erforderlich sein kann. Softwareanwendungen sind möglicherweise nicht mit allen Betriebssystemen kompatibel. Weitere Informationen erhalten Sie beim Anbieter der Anwendung.

2. Kein Computer bietet unter allen Bedingungen absolute Sicherheit. Für die Intel® Trusted-Execution-Technik sind ein Computer mit Intel® Virtualisierungstechnik sowie ein für die Intel Trusted-Execution-Technik geeigneter Prozessor, Chipsatz, BIOS-Code, entsprechende Authenticated-Code-Module und ein mit der Intel Trusted-Execution-Technik kompatibles MLE (Measured Launched Environment) erforderlich. Voraussetzung für die Intel Trusted-Execution-Technik ist außerdem die Ausstattung des Systems mit einem TPM v1.2.
