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, including:

  • Speeding up the transfer of platform control between the guest OSs and the VMM
  • Enabling the VMM to securely assign specific I/O devices to specific guest OSs
  • Optimizing the network for virtualization with adapter-based acceleration

Virtualization is being used in a wide variety of industries and systems for new virtualization-based capabilities, including disaster recovery, high availability, and business continuity.


Hardware-assisted Intel® VT is built into every aspect of server platforms based on Intel® processor technology.

Speed up data movement and reduce the performance overhead of virtualization with Intel® Virtualization Technology for Directed I/O.


Intel® Virtualization Technology (Intel® VT) for Connectivity (Intel® VT-c) is a collection of I/O virtualization technologies that enables lower CPU utilization, reduced system latency, and improved networking and I/O throughout. Intel® VT-c is one of the key component technology suites under Intel Virtualization Technology.

Intel® VT-c provides I/O technologies and optimizes virtualized performance through:

  • Enhanced data acceleration across the Intel multi-core processor platforms
  • Improved data processing performance across multiple queues on the network controller

Direct VM connectivity and data protection between the VMs

Next-generation virtualization

Intel® VT-c consists of platform-level technologies and initiatives that work together to deliver next-generation virtualized I/O including Virtual Machine Device Queues (VMDQ) and Virtual Machine Direct Connect (VMDC).

Product and Performance Information


1. Intel® Virtualization Technology requires a computer system with an enabled Intel® processor, BIOS, virtual machine monitor (VMM) and, for some uses, certain platform software enabled for it. Functionality, performance or other benefits will vary depending on hardware and software configurations and may require a BIOS update. Software applications may not be compatible with all operating systems. Please check with your application vendor.
