Client-side virtualization framework

Abstract

The invention discloses a client-side virtualization framework and realizes a client-side virtualization method based on difference synchronization and closed computation, wherein the client-side virtualization framework comprises a client-side system, a server side system, a virtual desktop server, a virtual machine monitor server, a client-side virtualization mirror image synchronous protocol and a virtual desktop / virtual machine monitor remote desktop transmission protocol; the client-side system comprises data, application program, a virtual machine, a virtual machine monitor, client-side hardware and client-side management software; the server side system comprises server side management software, a server virtualization component, server hardware and server storage equipment; the server storage equipment comprises a server local magnetic disc or a network magnetic disc connected with a server; and the server storage equipment reserves user data, application program mirror images, virtual machine mirror images and virtual machine monitor binary code.

Description

technical field [0001] The invention relates to the technical field of virtualization, and more specifically, relates to a client virtualization architecture utilizing differential synchronization and closed computing. Background technique [0002] In the past, a diskless workstation was a computer without a hard disk that operated a remote desktop. This desktop is obtained by transferring the desktop of the operating system on the physical server in the remote computer room. [0003] The technology of operating system virtualization causes multiple operating systems to run on one server, which can make full use of the server capacity in the computer room and reduce the cost of purchasing servers. The principle of virtualization, in short, is to make multiple "client" operating systems (or called virtual machine Virtual Machine, hereinafter referred to as virtual machine, VM, commonly known as Guest in English) run on a virtual machine monitor (Virtual Machine Monitor, here...

Problems solved by technology

Collective pays attention to the use of cache to solve the delay problem of mirror transmission, but does not use difference to reduce the content size of transmission

And because the Wei Rui products used cannot be open source, it is impossible to borrow the isomorphism of the virtual machine (for example, the virtual machines are all Windows or all Linux) to reduce the application / virtual machine image storage capacity of a large number of users

[0007] Offline VDI uses a layering (Iayering) method, but applications that are closely integrated with the operating system during deployment and runtime, such as Windows applications, often affect the system registry (Registry), generally difficult to layer, and application virtualization must be used preprocessing and does not perform client-side application virtualization

[0008] Additionally, the performance of offline VDI is unavailable in many industry sectors

For example, the security required by schools or government units needs to be at the hardware level, which cannot be met by the current offline VDI

The technology of replacing the current restore card with a PC in an Internet cafe cannot be solved by offline VDI at present

In addition, the student workstations in the training center need to change different operating systems frequently, and other requirements cannot be met.

Therefore, the method adopted by offline VDI does not solve the deep problem
