Graphic processing method, guest operating system (os) and guest os system

Abstract

Embodiments of the present invention provide a graphic processing method, a guest Operating System (OS) and a guest OS system, relate to the field of computers, and improve the reliability and fault recovery ability of a Graphic Processing Unit (GPU) sharing system. The solution comprises: a graphic drive of a guest OS sends a graphic processing instruction to a sharing rendering server, so that the sharing rendering server performs 3D graphic rendering on the basis of the graphic processing instruction; a display server monitors the status of the sharing rendering server; when determining that a fault occurs in the sharing rendering server, the display server sends an indication message to the graphic drive, so that the operating mode of the graphic drive is switched from 3D operating mode to 2D operating mode on the basis of the indication message; and the guest OS adopts a local rendering server to perform 2D graphic rendering on subsequent graphic processing instructions to obtain 2D image data.
