  Later, it was branded as APIC virtualization (APICv)
  and it became commercially available in the Ivy Bridge EP series of Intel CPUs, which is sold as Xeon E5-26xx v2 (launched in late 2013) and as Xeon E5-46xx v2 (launched in early 2014).
  Graphics processing unit
  Graphics virtualization is not part of the x86 architecture. Intel Graphics Virtualization Technology (GVT) provides graphics virtualization as part of more recent Gen graphics architectures. Although AMD APUs implement the x86-64 instruction set, they implement AMD's own graphics architectures (TeraScale, GCN and RDNA) which do not support graphics virtualization. Larrabee was the only graphics microarchitecture based on x86, but it likely did not include support for graphics virtualization.
  Chipset
  Memory and I/O virtualization is performed by the chipset. Typically these features must be enabled by the BIOS, which must be able to support them and also be set to use them.
  I/O MMU virtualization (AMD-Vi and Intel VT-d)
  An input/output memory management unit (IOMMU) allows guest virtual machines to directly use peripheral devices, such as Ethernet, accelerated graphics cards, and hard-drive controllers, through DMA and interrupt remapping. This is sometimes called PCI passthrough.
