Virtualization

CPU
  • VT-x
  • Intel started to include Extended Page Tables (EPT),[23] a technology for page-table virtualization,[24] since the Nehalem architecture,[25][26] released in 2008. In 2010, Westmere added support for launching the logical processor directly in real mode – a feature called “unrestricted guest”, which requires EPT to work.[27][28]
  • Since the Haswell microarchitecture (announced in 2013), Intel started to include VMCS shadowing as a technology that accelerates nested virtualization of VMMs
  • VT-c Intel's “Virtualization Technology for Connectivity”
I/O MMU
  • VT-d Virtualization Technology for Directed I/O – PCI passthrough
Other
  • PCI-SIG Single Root I/O Virtualization (SR-IOV) – In SR-IOV, the most common of these, a host VMM configures supported devices to create and allocate virtual “shadows” of their configuration spaces so that virtual machine guests can directly configure and access such “shadow” device resources.[50] With SR-IOV enabled, virtualized network interfaces are directly accessible to the guests,[51] avoiding involvement of the VMM and resulting in high overall performance
