Abstract

The invention discloses a method and a device for realizing desktop access of a virtual machine. Wherein the virtual machine comprises an analog display adapter and a GPU straight-through display adapter, and the method comprises the step of synchronizing data in a frame cache of the GPU straight-through display adapter into a frame cache of the analog display adapter when the GPU straight-throughdisplay adapter is available.

Description

technical field [0001] The present application relates to but not limited to the communication field, and in particular relates to a method and a device for realizing virtual machine desktop access. Background technique [0002] A virtual machine (VM, Virtual Machine) is a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. With the continuous development of virtual machine technology, taking a virtual machine deployed on a server as an example, the virtual machine can directly access a GPU (Graphics Process Unit, graphics processing unit) of the server, that is, the GPU passes through the virtual machine. However, in the scenario where the GPU is directly connected to the virtual machine, the desktop of the virtual machine can only be accessed through a specific protocol (for example, Microsoft's remote desktop protocol, Citrix's HDX (High Definition Experience, high-definition expe...
