Method and device for constructing multilayered virtual operating system

Abstract

The invention provides a method and a device for constructing a multilayered virtual operating system, wherein the method comprises the steps: a blank virtual environment and a virtual environment configuration database are constructed; a virtual environment superposition database is opened to obtain a desktop layer, an application layer and a data layer of a user, which are all designated by theuser, the desktop layer, the application layer and the data layer are loaded to the blank virtual environment by modifying the virtual environment configuration database, wherein the desktop layer comprises all the data required by the tailored configuration of the desktop of the blank virtual environment, the application layer comprises all the data required by running specific applications in the blank virtual environment, and the data layer stores all the data of the user; the data stored in the data layer is updated in accordance with the data variation which is resulted from the operationof the user on the data in both the desktop layer and the application layer, so that the user can copy the desktop layer, the application layer and the data layer in a storage medium or a service, thus realizing real mobile officing.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer virtualization technology, and in particular to a method and device for constructing a multi-layer virtual operating system. Background technique [0002] Among related technologies, due to the continuous improvement of modern information technology, the information technology (Information Technology; hereinafter referred to as: IT) system of enterprises is constantly expanding. With the continuous increase of hardware inventory, the traditional IT management mode has resulted in the status quo of low system utilization and rapid increase in maintenance costs. [0003] Virtualization technology can effectively reduce the complexity of IT management, simplify IT facilities, and bring more effective IT management mode and cost control to enterprises. Virtualization technology is divided into virtual operating system and virtualization architecture. The virtual operating system (Vir...

Problems solved by technology

[0007] Since the addition, deletion or modification of data by the user in the virtual machine needs to be directly written to the virtual hard disk in the virtual machine, the virtual machine cannot distinguish between the original data, configuration, and programs of the user and the system, so it cannot be used only for users. The user's data, configuration, and program can be backed up, shared, or processed, and the user cannot place the system on an external storage device and take it away
