Intel Virtualization Technology (Intel VT)
Intel Virtualization Technology, or Intel VT, is a set of technologies from Intel for virtualization. It was introduced at the Intel Developer Forum in 2003,[3] and launched at the Intel Developer Forum in 2005.[citation needed] Intel VT is composed of Virtualization Technology for IA-32 (VT-x), Virtualization Technology for IA-64 (VT-i), Virtualization Technology for Directed I/O (VT-d), and Virtualization Technology for Connectivity (VT-c).
Virtualization Technology for IA-32
Virtualization Technology for IA-32 (VT-x), previously codenamed "Vanderpool", is Intel's technology for virtualization on the IA-32 platform. Intel plans to add Extended Page Tables (EPT),[4] a technology for page table virtualization,[5] in the upcoming "Nehalem" architecture.[6]
Virtualization Technology for IA-64
Virtualization Technology for IA-64 (VT-i), previously codenamed "Silvervale", is Intel's technology for virtualization on the IA-64 (Itanium) platform.
Virtualization Technology for Directed I/O
Intel's Virtualization Technology for Directed I/O (VT-d) is a technology that enables guest virtual machines to directly use peripheral devices, primarily through DMA and interrupt remapping.
Virtualization Technology for Connectivity
Intel's Virtualization Technology for Connectivity (VT-c) is itself a collection of technologies that assists in I/O virtualization. It is composed of Virtual Machine Device Queues (VMDq), Intel I/O Acceleration Technology (I/OAT), and Single Root I/O Virtualization.[10] Intel QuickData Technology is a component of Intel I/OAT.[citation needed]
