Hardware acceleration can be done using PCI passthrough to pass your graphics card on to the guest OS. IOMMU and VFIO are two terms I commonly see associated with this, but having never done it myself I am not sure what the difference between them is - perhaps someone can chime in?

VT-d = Virtualization Technology for Directed I/O which basically means the CPU has an IOMMU, the IOMMU is a piece of hardware for doing PCIe DMA re-mapping to provide VM isolation. VFIO is the linux driver for passing through IOMMU devices.
