METHOD AND SYSTEM FOR CAPTURING A FRAME BUFFER OF A VIRTUAL MACHINE IN A GPU PASS-THROUGH ENVIRONMENT

摘要

A method for capturing information in a graphics processing unit (GPU) pass-through environment. The method includes installing a guest driver of a dedicated GPU within an assigned virtual machine. The GPU is assigned by a hypervisor configured for managing a plurality of virtual machines. The guest driver directly controls the GPU to render a plurality of frames. The method includes capturing a first frame stored in a frame buffer of the GPU. The method includes storing the first frame for later access, such as for management of the virtual machine by viewing a desktop captured in the first frame.

1. A system comprising:
a processor; and non-transitory memory coupled to said processor and having stored therein instructions that, if executed by said computer system, cause said computer system to execute a method for capturing information comprising:
installing a guest driver of a dedicated graphics processing unit (GPU) within an assigned virtual machine, wherein said guest driver directly controls said GPU to render a plurality of frames for said virtual machine;capturing a first frame stored in a frame buffer of said GPU; andstoring said first frame for later access.
