Step 1 reads user's data Layer record in virtual environment superposition of data storehouse;
Step 5 is revised the virtual registration table configuration data of current virtual environment configuration database, and the registration table configuration data of data Layer is integrated with in the registration table of current virtual environment.
Through above-mentioned processing, can data Layer be loaded in the blank virtual environment of structure.
Need to prove that the processing procedure of multilayered virtual operating system construction method as shown in Figure 1 can be accomplished, and has promoted security of system greatly under user's pattern, and can intercept the interference of viral wooden horse fully.
The multiple field virtual environment of the embodiment of the invention (Multilayer Virtual Environments; Hereinafter to be referred as: MVE) the blank data Layer that can on the blank virtual environment of standard, superpose, this data Layer can be stored any interpolation or the modification that the user is made in this virtual environment.No matter the user is installation procedure, modification configuration or additions and deletions file in virtual environment, all changes all can be kept in user's the data Layer, can not have influence on the originally clean virtual environment of bottom.
In addition; User's data Layer can separately leave convenient backup in the hard disk of diverse location in; Also can leave on the webserver, perhaps be carried in the portable hard drive, when opening virtual environment by the user; The embodiment of the invention can read user's data Layer automatically, and this data Layer is merged in the virtual environment.
In addition, the embodiment of the invention can also let user's specific virtual level of multilayer that superposes except the blank data virtual layer that can superpose.Can also isolate in-local system and virtual opetrating system fully, this machine system can be affected.
In the multiple field virtual environment, all are superimposed upon data or application program in the virtual level on the virtual environment, can use as being installed in the virtual environment, and that has realized application program exempts to install, exempt from unloading.
The user can also make application layer to other application program, and the application layer of in virtual environment, specifying stack to make.In addition, the user also can be installed to required application program, file and desktop configure in the same virtual level and be made into table surface layer, and can in virtual environment, specify this table surface layer of stack.For example, if the user has been packaged in WORD in table surface layer, so the user loaded change table surface layer after, just can directly use WORD.If table surface layer is placed in the server, can be with traditional desktop environment networking.Make the application program in the virtual opetrating system be able in the different virtual environment, share also and can share with other users in the network.
Below, in conjunction with Fig. 6, the flow process of the above-mentioned processing of the embodiment of the invention being elaborated, Fig. 6 is the process flow diagram of detailed process of the multilayered virtual operating system construction method of the embodiment of the invention, and is as shown in Figure 6, comprises following processing:
Step 1 is according to the blank system environments of the configuration database construction of system;
Step 5, the stack table surface layer;
Step 7, the application layer of all user's appointments that superpose;
The process of above-mentioned processing can all be accomplished on client computer, has made full use of client resource, reduced server load, increased the efficient of entire system; Avoided in the prior art owing to virtual environment is arranged at the network that causes at server end and the excessive problem of load of server.In embodiments of the present invention, virtual environment, application program and data all can be buffered in computing machine this locality, when practical application, only need get final product from the part of down loading updating on the server, and the demand of the network bandwidth is significantly reduced; Overcome in the prior art owing to system and user's data data can only be placed on the problem that causes network bandwidth waste on the server.
In practical application and since in the embodiment of the invention in the multilayered virtual operating system dirigibility of each virtual level strong, can with other virtual technology platforms and other instruments, for example, VM or Remote Desktop unite use.
In addition, the embodiment of the invention makes data, virtual environment and application program to cut apart and is kept at different memory locations through exclusive layering stacked system, realizes disperseing storage, makes things convenient for data backup, is beneficial to the management and the safety of data; Application program and data separate storage in the virtual opetrating system help the information management in the enterprise.In addition; The embodiment of the invention can also be with virtual environment, program, transfer to different servers respectively with data stores and manages; Except can the burden of distributing server, also can avoid risk because of the single server fault causes system to move or data are lost.
The embodiment of the invention is through moving and reproduction the multilayer virtual environment; Can support the mobile office of line and off-line type simultaneously; Strengthened the dirigibility of the dynamics and the system of resource sharing, in addition, the embodiment of the invention is except can making full use of the enterprises'original client computer; In virtual environment, extra OS need be installed, significantly reduce building of system and be set to this.
