S304 takes over the Service controll manager of operating system, obtains the autonomous system service of this virtual environment.
Further, the method also comprises:
S305, the step of startup figure shell is graphically to call system resource for the user.
The initial processes of the startup virtual system in step S301 is specially:
Start the corresponding application program of loader operation, the logic of operation virtual machine oneself.
The follow-up subprocess that described initial processes in step S302 starts comprises:
Described initial processes continues procreation, obtains subprocess, Sun Jincheng, to such an extent as to produce an ethnic process that obtains this initial processes.
One of them ethnic process has identical label, is placed in same container.
The manager of Service controll described in step S304 is used for starting and managing the background service program, and described adapter Service controll manager comprises a series of related service process of taking over.
For making principle of the present invention clearer, the below describes the structure flow process of a kind of virtual environment provided by the invention in detail.
The first step-startup loader:
Described loader is mainly be used to allowing the user move the implementing procedure of other application programs, is the virtual machine process that at first starts, and loader is understood the static loading logic processing module as first process of virtual system, the logic of operation virtual machine oneself.
Second step-operation logic processing module: comprise interception injection module, file system module, configuration data module and mixed-media network modules mixed-media etc. in this logic processing module.
This logic processing module has the logic process of joining two pipes together exactly, as its name suggests, subprocess by first process initiation all will be taken over, image is exactly that first process can create subprocess, this subprocess can produce again the subprocess (being called " Sun Jincheng ") that makes new advances, continue like this procreation, formed an ethnic process.The group of the ethnic process of saying here can liken a present operating system to, can certainly be virtual system.
When program design, some concrete functional modules can realize by different forms such as function or threads.For same process, these functions, thread all are present under same address space, and when carrying out, mostly only more relative data are processed.If there is certain mistake in algorithm, might destroy some other important content of the address space that exists together with it, this will cause more serious consequence.Can consider those operation parts that need to conduct interviews to the data in address space are put in the address space of another one process for the content of protection in address space and move, and only allow related data in the former process address space of its access.Concrete, can create a subprocess according to existing method.Subprocess is all only conducting interviews to the related data in the parent process address space in processing procedures, thereby can protect in the parent process address space and the current subprocess irrelevant total data of executing the task.For this situation, the effect that subprocess embodies is more similar with thread with function, can regard parent process as in a process of run duration.For this reason, need to by parent process grasp subprocess startup, carry out and withdraw from.
The 3rd the step-process is put into program containers:
In operating system, several program is placed in a container and (is called " program containers ", Process Container), authority can be deleted or arrange to convenient management simultaneously.
During the promoter process, it is exactly when the subprocess that starts that logic processing module has again a logic, before this (child) process is arranged label startup loader, generating an identifier is global unique identification symbol (GUID, Globally Unique Identifier) number assignment is to loader, by the unique virtual machine of this segment number code sign, which program containers is identification process belong to, the subprocess that label is identical is placed in same container, and namely each virtual machine takies a program containers.The group of a foregoing class race process just takies a program containers.This process of description of image, a yellow's offspring is exactly the yellow exactly, constantly inverting is also the yellow, this has obvious color distinction with Black people and white man, so be easy to recognize and belong to the sort of people, this colour of skin just is equal to the label of process, and then the process with all same labels is referred in a container, the user of convenient sign virtual machine.N user's virtual machine independently is independent of each other fully like this.
the operation of carrying out in corresponding virtual opetrating system in order to put down in writing the user, also need at least one configuration database is written into internal memory, wherein, configuration database is used for the configuration data of the subsystem of record virtual opetrating system, user's deposit data position, and described user operate in corresponding virtual opetrating system record deposit position, wherein, described subsystem can comprise following one of at least: file subsystem, the configuration data subsystem, the interception subsystem, filter subsystem, the separaant system, the Service controll subsystem, network control subsystem etc., each subsystem function is as follows:
File subsystem: be used for the reorientation of file path;
Configuration data subsystem: be used for the reorientation in configuration data path;
The interception subsystem: being used for interception is the operation entry point, and derives from the succession operation;
Filter subsystem: be used for the file resource filtering screening;
Separaant system: be used for the reorientation of kernel objects;
Service controll subsystem: be used for the processing of Service Privileges;
Network control subsystem: be used for the distribution of virtual IP address.
In the application of reality, if build a plurality of virtual (operating system) environment, can a configuration database (memory database) all be set for each virtual opetrating system; Also a configuration database can only be set, and this configuration database is shared for a plurality of virtual opetrating systems.When configuration database was set to a plurality of virtual opetrating systems and shares, the configuration in a virtual opetrating system can be applied to a plurality of virtual opetrating systems; For example, configure MSN in a virtual opetrating system, shared if configuration database is set to a plurality of virtual opetrating systems, be equivalent to also be equipped with in other virtual opetrating systems MSN.
The 4th go on foot-takes over and starts system service:
Take over the service manager of operating system, service manager is called again Service Manager orSuper Daemon, is mainly start and manage the background service program.
The 5th step-startup figure shell:
The figure shell is the Shell program, is used for showing all program of desktop.If it is uncultivated that this program of off-duty, desktop will be a slices, the user can't operate this desktop fully.
Starting the figure shell can such as the user can see file, see catalogue, see the hard drive space of oneself with the calling to the user of system resource " graphically ", and the figure shell of virtual environment is shown to the manipulable resources of virtual machine of user exactly.
With reference to Fig. 4, the present invention also provides a kind of system that realizes virtual environment, and 400, comprising:
Take over module 45, be used for taking over the Service controll manager of operating system, obtain the autonomous system service of this virtual environment.
This system also comprises:
After described adapter module is taken over the Service controll manager of operating system, show the figure shell of virtual environment.
The embodiment of the present invention is due to the kernel that does not need to revise the in-local system, therefore, can not cause the low or collapse of the usefulness of system; Improved the performance of system.In addition, because virtual opetrating system and the kernel of the embodiment of the present invention are isolated, can not affect original operating system, even the in-local system upgrades, can not cause the program of virtual opetrating system to move yet.
