An input/output memory management unit (IOMMU) enables 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. Both AMD and Intel have released specifications:
AMD's I/O Virtualization Technology, "AMD-Vi", originally called "IOMMU"
Intel's "Virtualization Technology for Directed I/O" (VT-d)
Verovatno VMware ne traži striktno da to mora postojati, ali verujem da sigurno ima podršku i da ume da iskoristi, a ne deluje mi da je baš za bacanje
