Abstract
The invention provides a method and a system for graphic card redirection. The method comprises the steps of a, an application program unit sends a display request to an operating system of a virtual machine; b. a server virtualization system unit receives orders of the display request and sends the orders to a client end; and c. the client end decodes the display orders and conducts corresponding processing. The display orders are transmitted to the server virtualization system unit through a virtual graphic card driving unit, then the display orders are processed by a graphic card simulator unit in the server virtualization system unit and packaged to transmit to the client end through a display protocol service unit, and the display orders are decoded and processed through the client end. According to the method and the system, two-dimension (2D) and three-dimension (3D) acceleration can be supported, a virtual desktop system has strong graph processing capacity, and simultaneously the virtual desktop system breaks away from a virtual machine network to provide reliable desktop services.
