Intel® Virtualization Technology (Intel® VT) consists of technology components that support virtualization of platforms based on Intel® processors, thereby enabling the running of multiple operating systems and applications in independent partitions. Each partition behaves like a virtual machine (VM) and provides isolation and protection across partitions. This hardware-based virtualization solution, along with virtualization software, enables multiple usages such as server consolidation, activity partitioning, workload isolation, embedded management, legacy software migration, and disaster recovery.

Intel® Virtualization Technology (Intel® VT)
Hardware support for processor virtualization enables simple, robust and reliable VMM software. VMM software relies on hardware support on operational details for the handling of events, exceptions and resources allocated to virtual machines.

Intel® Virtualization Technology (Intel® VT) for Directed I/O (Intel VT-d)
Intel® VT-d provides additional performance, security and flexibility by providing the VMM with the following capabilities:

• I/O device assignment - for flexibly assigning I/O devices to VMs and extending the protection and isolation properties of VMs for I/O operations.
• DMA remapping - for supporting independent address translations for Direct Memory Accesses (DMA) from devices.
• Interrupt remapping - for supporting isolation and routing of interrupts from devices and external interrupt controllers to appropriate VMs.
• Reliability - for recording and reporting to system software DMA and interrupt errors that may otherwise corrupt memory or impact VM isolation.

For Intel VT or Intel VT with Directed I/O support, desktop boards require the following:

• Intel® processor that supports Intel VT
• Desktop board BIOS with Intel VT support
• Additionally, a third party VMM may also be required.

Follow these steps to find out if your Intel® desktop board configuration supports Intel® VT:

1. Install a processor that supports Intel VT.
2. Enter the system BIOS by pressing F2 during boot.
3. On the Security menu, check for an option to enable/disable Intel VT or Intel VT with Directed I/O. If this option is present, your system supports Intel VT.

To see if your processor supports Intel VT, refer to Does my processor support Intel® Virtualization Technology?
