Embodiment
The embodiment of the invention combines virtual machine technique with mirror image technology, when saving the server stores space, can also provide the individuation data service for the user.Below in conjunction with accompanying drawing, the present invention is described further by specific embodiment.
In the operation method of the terminal that present embodiment provides, described terminal is connected with a server.As shown in Figure 1, described operation method may further comprise the steps:
By above step as can be seen, in the said method, bitmap has been preserved the information of the individuation data of terminal needs, based on bitmap and basic mirror image, can be that different terminals generates personalized virtual disk.Simultaneously, because server side only need preserve a basic mirror image, therefore conserve storage resource greatly.
Below said method is elaborated.
The embodiment of the invention only need be preserved an image file at the server place, promptly basic mirror image comprises first and at least one second portion in this basis mirror image.Common, described first is the disk sector of operating system correspondence, described second portion is mounted in the disk sector of the application program correspondence on this operating system.When server is in set up applications, can obtain the disk sector of application file correspondence.
Simultaneously, the server place also preserves corresponding to the bitmap of the attribute of each terminal (bitmap), includes the information whether disk sector of each described at least one second portion correspondence can visit in the described bitmap.Wherein, whether each described second portion can visit, and is definite according to the attribute (as the login user of this terminal) of this terminal in advance.For example, when login user needed certain application program, the disk sector of this application program correspondence in bitmap was set to and can visits this moment; Otherwise, then be arranged to and can not visit.Like this, present embodiment utilizes bitmap to preserve the information which application program is terminal need, and providing at the individuation data of terminal has been provided.
Bitmap can adopt the expression mode of binary number mapping.For example, a disk sector of second portion in the corresponding basic mirror image of the bit of each in bitmap (bit).When this bit value was 0, the disk sector of representing this bit correspondence was that this terminal can not be visited, and when this bit value was 1, then expression was that this terminal can be visited.Because when set up applications, operating system can be obtained the corresponding relation of application file and disk sector, therefore can generate the bitmap of this terminal according to the pairing disk sector of application program of operating system and terminal needs.
Here, the attribute of described terminal can be the IP address of terminal, at this moment, determine the bitmap of this terminal correspondence according to the IP address of terminal, promptly login the different user of same terminal or use the different client operating systems of same terminal, because have identical IP address, so identical bitmap is all arranged, the final virtual disk that generates all is identical; The attribute of described terminal can also be the login user of terminal, as login username and password, at this moment, logins the different user of same terminal, each self-corresponding bitmap not simultaneously, the final virtual disk difference that generates.
Before above-mentioned steps 11, the operation method of the described terminal of present embodiment also comprises:
Step 10 behind the terminal electrifying startup, is carried out initial work, comprises by network going out to download start-up code from server, and according to described start-up code, guiding virtual machine (VM, Virtual Machine) starts.
In the above-mentioned steps 11～12, after virtual machine activation is finished, obtain the bitmap of the attribute correspondence of basic mirror image that described server preserves and this terminal, the attribute of described terminal is specially the IP address of described terminal or the login user of described terminal.For example, when described attribute was the IP address of terminal, virtual machine was to the IP address of server transmission terminal, and server receives this IP address, determines the bitmap of this IP address correspondence, and the bitmap with correspondence sends to this virtual machine then.Again for example, when described attribute is the login user of terminal, virtual machine receives the identity information (as username and password) of login user input and sends to server, server receives this identity information and carries out authentication, after checking is passed through, determine the bitmap of this login user correspondence according to identity information, and then the bitmap of correspondence is sent to this virtual machine.
In the above-mentioned steps 13, described according to described basic mirror image and described bitmap, generate described terminal corresponding virtual disk, specifically comprise:
Step 131 after virtual machine activation is finished, according to described basic mirror image, starts client operating system.
Here, after virtual machine activation was finished, virtual machine was according to described basic mirror image, and the guiding client operating system starts, and specifically comprises: foundation is connected with described basic mirror image; Described basic Mirroring Mapping is become a local drive; Start client operating system from this drive.
Step 132 is tackled the first disk read command that produces in the start-up course of described client operating system;
Here, in the start-up course of client operating system, by the virtual machine manager (VMM, Virtual Machine Monitor) of virtual machine, interception comprises the magnetic disc i/o operational order of disk read command.
Step 133 is resolved the described first disk read command, obtains the first corresponding disk sector;
Step 134 when described first disk sector is the disk sector of described first correspondence, generates disk sector corresponding in the described virtual disk according to described first disk sector; When described first disk sector is the disk sector of described at least one second portion correspondence, according to described bitmap, judge whether described first disk sector can visit: when described first disk sector can be visited, generate disk sector corresponding in the described virtual disk according to described first disk sector; When described first disk sector can not be visited, return the indication of the described first disk sector free of data.
In the above-mentioned steps 134, behind first disk sector that obtains the described first disk read command correspondence, judge the part under first disk sector is in described basic mirror image:, then directly generate disk sector corresponding in the described virtual disk according to described first disk sector if first disk sector is the disk sector of described first; If first disk sector is the disk sector of described second portion, then need further to judge according to described bitmap whether first disk sector can visit, in the time can visiting, just generate disk sector corresponding in the described virtual disk according to described first disk sector, return the indication of the described first disk sector free of data in the time can not visiting, generate corresponding data this moment in virtual disk be empty disk sector.
For example, when first disk sector can be visited, virtual machine manager can all be changed to the value of an internal memory 1 (complete 1 expression is without any data), and indicating what preserve in this internal memory of client operating system then is the data of first disk sector; After client operating system reads complete 1 data of this internal memory, will think in first disk sector be empty corresponding disk sector without any data so generate data, start-up course is down carried out in continuation then.
Through above step, client operating system after startup is finished, the application program of installing carried out full scan after, can obtain the needed application program of this terminal, the unwanted application program of this terminal then can not be installed in this client operating system.
From the above as can be seen, present embodiment is in the start-up course of client operating system, according to the bitmap that sets in advance, sector in the basic mirror image is filtered, the client operating system that comprises different second portions (application program) is provided for different terminals, thereby realized the individuation data service of terminal, different user has been embodied different operative scenario.Simultaneously, because the server place only need preserve a basic mirror image, when having avoided preserving a plurality of mirror image, the waste of the basic operating system mirror image that comprises in each mirror image or the application program storage resources that mirror image causes of repetition.
