The Optimization of Xen-Based Display Virtualization

Virtualization technology can reuse the hardware platform to provide multiple isolated virtual system environments; however, this also causes unsatisfactory performance of the virtual guest system, especially the display in virtual guest system. In this paper, we study the virtual device model and improve the way of original virtual device implement based on Xen virtualization. A new display method is adopted which does improve the display environment of virtual guest system effectively.
