%X Mainstream device emulation models suffer from low performance and non-security. A novel high performance device virtualization of directly assigning model with hardware IOMMU support was presented, and was implemented as the display device solution on Xen. This model is more secure than para-virtual device model based IOVM architecture. Viewperf benchmark test result indicates this implementation's performance is close to non-virutal system, much better than traditional device emulation model.
