System and method for supporting 3D application in virtual environment

Abstract

The invention discloses a system and a method for supporting a 3D application in a virtual environment, and belongs to the technical field of computer virtualization. The system specifically comprises three parts of a host machine, a virtual machine and a terminal. A 3D session is analyzed by utilizing DirectX and OpenGL of a bottom layer, between the host machine and the terminal; a 3D operation instruction is intercepted and captured at the bottom layer and encapsulated; and a graph of the virtual machine is fluently displayed on a display of the terminal in combination with display protocol transmission of a remote desktop in a 3D instruction redirecting mode, so that a display card on the terminal is fully utilized for performing high-performance and high-simulation 3D rendering, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of computer virtualization, in particular to a system and method for supporting 3D applications in a virtualized environment. Background technique [0002] Virtualization technology has brought many benefits to enterprises in terms of saving IT hardware costs and improving server utilization. With the improvement and popularization of virtualization technology and management, more and more enterprises have begun to deploy virtualization solutions, including Server virtualization and desktop virtualization. At present, virtualization technology basically uses the VT technology provided by Intel and AMD to simulate various resources required by all systems through the Hypervisor layer, such as CPU, memory, network card, sound card, hard disk, etc. At present, these technologies can make operating systems such as Windows / Linux / Unix run smoothly on virtualization, and software other than 3D can basically be use...

AI Technical Summary

Problems solved by technology

Its advantages: no physical graphics card, simple; disadvantages: due to the difference between CPU and GPU (graphics processing unit), CPU cannot provide high processing performance, and can only meet general 3D graphics processing

Disadvantages: The graphics card is monopolized and cannot be shared by multiple virtual machines. In a desktop virtualization environment, a host usually needs to host dozens of virtual machines, and the exclusive method obviously cannot satisfy the use of several virtual machines. Each virtual machine needs a graphics card, so the cost is also very expensive; it cannot meet the scenario of dynamic migration of virtual machines between different hosts

Disadvantages: Professional graphics cards are required to support them, such as Nvidia's K1 / K2. Although they can be virtualized for multiple virtual machines, the cost of graphics cards that support virtualization is expensive, so the cost is still not low; the data rendered by the graphics card It needs to be transmitted to the virtual machine again, and the rendered graphics data is very large, which will have a certain impact on performance

Usually the rendering of 3D software depends on the graphics card, and due to the particularity of the graphics card, the graphics card is idle in most cases, because the remote display protocol basically transmits audio, keyboard and mouse events, 2D graphics output, etc. Less places to use the graphics card
