Intelligent display method based on SPICE protocol, which can support display card through and virtual display card

Abstract

The invention belongs to the technical field of virtual desktop, in particular to an intelligent display method based on SPICE protocol, which can support display card through and virtual display card. The method is implemented based on a display system. The display system comprises a virtual machine, a virtual desktop client, a SPICE server, a physical server and a virtual display card. The virtual machine comprises an agent module in the virtual machine and a display card driver. The physical server comprises a physical display card; The SPICE server comprises: a display information acquisition and control module; Compared with the prior art, the invention adopts the original SPICE protocol, can self-adapt two modes of physical display card transparent transmission and virtual display card, displays the virtual desktop, and has high compatibility with the original system. Virtual machine communicates with server through virtIO, and does not communicate with client directly, which improves system security.

Description

technical field [0001] The invention belongs to the technical field of virtualized desktops, and in particular relates to a SPICE protocol-based intelligent display method supporting graphics card direct connection and virtual graphics card. Background technique [0002] Existing virtual desktop solutions can only support one of the virtual graphics card or the graphics card pass-through method, and cannot support the virtual graphics card and the graphics card pass-through method at the same time. [0003] SPICE is an open source desktop virtualization data transmission protocol developed by redhat. It captures display information from the virtual graphics card provided by QEMU to the virtual machine, and sends it to the SPICE client through the display channel. It is widely used and can meet the requirements for graphics cards. Scenes. On the other hand, due to the large demand for graphics cards such as playing games, video playback, video processing, and 3D design, the ...

AI Technical Summary

Problems solved by technology

This type of method needs to add a shared memory allocation and management mechanism in QEMU, which is highly complex in management and control and difficult to implement

[0011] The disadvantage of the existing solution is that it cannot support both virtual graphics card and graphics card pass-through at the same time

[0012] For solutions that only support virtual graphics cards, their performance cannot meet the high-performance needs of users

[0013] For the solution that only supports graphics card pass-through, the original SPICE protocol has been greatly changed, and the compatibility with the original SPICE protocol-based virtual desktop system is poor; because virtual graphics cards are not supported, resources are wasted when high-performance display requirements are not required
