Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Referring to fig. 1, fig. 1 is a block schematic diagram of a terminal device 100 according to an embodiment of the present application, where the terminal device 100 may be a Personal Computer (PC), a server, or other similar devices. As shown in fig. 1, the terminal device 100 includes an operating system switching apparatus 200, a memory 110, and a processor 120.
The memory 110 and the processor 120 are electrically connected to each other directly or indirectly to achieve data transmission or interaction. For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The memory 110 includes software functional modules stored in firmware or software (software), and the processor 120 implements corresponding functional applications or data processing by executing the executable modules in the memory 110. For example, the os switching device 200 is stored in the memory 110 and is controlled to be executed by the processor 120.
In addition, the memory 110 stores therein an operating system VHD file and a first differencing VHD file created based on the operating system VHD file. The vhd (virtual Hard disk) file is an abbreviation of microsoft virtual Hard disk file, which is a disk file format. Files in VHD format can be compressed into a single file to be placed on the file system of the host machine. In this embodiment, the operating system VHD file corresponds to a virtual hard disk on which an operating system is packaged. The terminal device 100 can directly start the virtual operating system from the operating system VHD file through the native vhdboot technology.
The first differencing VHD file refers to a differencing disk (also referred to as a "differencing disk") created using the operating system VHD file as a master disk (also referred to as a "parent disk"). In this embodiment, the first differencing VHD file includes a preset application.
When the system disk is restarted with the first differencing VHD file, the terminal device 100 loads the operating system in the master disk (operating system VHD file) of the first differencing VHD file and the data in the first differencing VHD file in sequence.
Therefore, in the case that the first differencing VHD file is created and is not modified, the operating system that is run by the terminal device 100 after the restart with the operating system VHD file as the system disk is consistent with the operating system that is run by the terminal device 100 after the restart with the first differencing VHD file as the system disk. However, when the terminal device 100 restarts using the first differencing VHD file as a system disk, data generated by operations performed on the operating system are all saved in the first differencing VHD file.
In practical applications, users may have different requirements for the operating system, and for this case, a plurality of operating system VHD files may be provided, each of which encapsulates a different operating system. The operating system may be an operating system of the professional version of Windows7 or a version thereof (e.g., Windows8, Windows10, etc.), and of course, the operating system may also be other operating systems capable of supporting VHD files, which is not limited in this embodiment.
In practical applications, there is an association relationship between the applications that the user needs to use, and when the user performs a corresponding operation on one of the applications, the user may affect the other applications, and it is uncertain which applications the user uses. Therefore, different applications can be stored in different first differencing VHD files to avoid interference between the applications.
Therefore, for a plurality of application programs that can run under the same operating system, a plurality of first differencing VHD files can be created using the operating system VHD file in which the operating system is packaged as a master disk, and the plurality of application programs can be stored in the plurality of first differencing VHD files, so that a plurality of first differencing VHD files corresponding to the plurality of application programs one to one can be obtained.
In one embodiment, the terminal device 100 may be a teaching terminal, which is used by a teacher when giving lessons or used by a learner when learning. The application program can be software which needs to be used together with different courses, for example, Office software which needs to be used for Office software teaching, Visual Studio software which needs to be used for programming courses, financial matching software which needs to be used for financial related courses, Photoshop software which needs to be used for multimedia courses, and the like. In this case, each of the first differencing VHD files actually corresponds to a different course, and thus, the first differencing VHD file can be named according to the course to which it corresponds, and thus, the user can search for the corresponding first differencing VHD file by the course name.
Further, when the terminal device 100 is a teaching terminal, a plurality of terminal devices 100 are generally available. For example, as shown in fig. 2, a plurality of terminal devices 100 for teaching in an electronic classroom, wherein the plurality of terminal devices 100 include a terminal device a for learners and at least one terminal device B for lecturers, and the terminal device B can be communicatively connected to the terminal device a through a network. At this time, the operating system VHD file and the first differencing VHD file based on the operating system VHD file may be prestored in the plurality of terminal apparatuses 100 by the following steps.
The method comprises the steps that a first terminal device receives a first selection instruction, determines a target operating system VHD file corresponding to the first selection instruction, creates a first difference VHD file based on the target operating system VHD file, and writes a preset application program into the first difference VHD file;
and the first terminal equipment prestores the target operating system VHD file and the first differencing VHD file to a specified second terminal equipment.
The creating of the first differencing VHD file based on the target operating system VHD file means that the target operating system VHD file is used as a master disk (or a parent disk) to create the first differencing VHD file, and the created first differencing VHD file is a differencing disk of the target operating system VHD file.
The first terminal device is a first terminal device 100 that creates the first differencing VHD file, and may be a terminal device a or a terminal device B shown in fig. 2; the second terminal device is the terminal device 100 that acquires and stores the target operating system VHD file and the first differencing VHD file provided by the first terminal device, and may be the terminal device a or the terminal device B shown in fig. 2. The first selection instruction refers to an instruction which is input by a user on the first terminal device and is used for selecting the operating system.
Optionally, the first terminal device may pre-store the target operating system VHD file and the first differencing VHD file to each second terminal device through the flash system.
In detail, after the first differencing VHD file is created on the first terminal device, the operating system of the first terminal device may be backed up, so as to obtain a system image file of the first terminal device, where the system image file includes the target operating system VHD file and the first differencing VHD file. Then, the obtained System image file is uploaded to a server of the System for flashing, each second terminal device enters a BIOS (Basic Input Output System) when being started, and the System image file is downloaded from the server of the System for flashing and installed, so that the target operating System VHD file and the first differential VHD file in the System image file can be obtained.
It should be understood that the structure shown in fig. 1 is only an illustration, and the terminal device 100 may further include more or fewer components than those shown in fig. 1, for example, the terminal device 100 may further include a display unit and a communication unit, where the display unit is used for establishing an interactive interface between the terminal device 100 and a user, or for displaying information to be displayed. The communication unit is used to establish a communication connection with an external terminal (e.g., other terminal device 100). Of course, the terminal device 100 may also have a different configuration from that shown in fig. 1. It should be noted that, the components shown in fig. 1 may be implemented by hardware, software or a combination thereof, and are not limited herein.
Please refer to fig. 3, which is a flowchart illustrating an os switching method according to an embodiment of the present application, where the os switching method is applied to the terminal device 100 shown in fig. 1. The specific steps of the method are described in detail below with reference to fig. 3.
Step S301, receiving a selection instruction, and determining a target first differencing VHD file corresponding to the selection instruction from the at least one first differencing VHD file, where the target first differencing VHD file includes a target application corresponding to the selection instruction.
The terminal device 100 stores an operating system VHD file and at least one first differencing VHD file created based on the operating system VHD file in advance. A target first differencing VHD file, meaning: the terminal device 100 pre-stores a first differencing VHD file corresponding to the received selection instruction in at least one first differencing VHD file.
When a plurality of first differencing VHD files are prestored in the terminal device 100, each first differencing VHD file includes a different application program. The target application program is an application program corresponding to the received selection instruction.
In one embodiment, the selection instruction may be a selection instruction input by the user on the terminal device 100 for selecting an application, where the selection instruction includes identification information of the application (i.e., the target application) selected by the user, such as an application name.
When the terminal device 100 is a teaching terminal, the application included in the different first differencing VHD file is an application necessary for a different course, that is, the different first differencing VHD file corresponds to a different course. Thus, each first differencing VHD file can be named according to its corresponding course. In this case, the selection instruction may be course information input by the user, so that the terminal device 100 may determine the corresponding first differencing VHD file according to the course information, i.e., the first differencing VHD file corresponding to the selection instruction.
In another embodiment, the selecting instruction may be a selecting instruction sent by other terminal devices 100.
For example, when the terminal device 100 is used by a learner in a teaching process, the terminal device 100 corresponds to the terminal device a shown in fig. 2, the selection instruction may be course information sent by the terminal device B, and based on the course information, the terminal device a may determine a target first variance VHD file corresponding to the course information from at least one first variance VHD file stored in advance. In detail, the terminal device a may find, from at least one first differencing VHD file stored in advance, a first differencing VHD file storing a course application (i.e., a target application) corresponding to the course information as the target first differencing VHD file.
Step S302, determining whether a second differencing VHD file created based on the target first differencing VHD file exists in the terminal device 100. If yes, go to step S303. If not, step S304 may be performed.
In the prior art, the operation is usually directly performed on the target application installed in the operating system, so that all the operations of the user are retained on the current target application, thereby affecting the use of other users. If the recovery is required, the recovery can be only realized manually, but the manual mode has low efficiency and is very easy to make mistakes.
Therefore, in the embodiment of the present application, a second differencing VHD file is created on the basis of a target first differencing VHD file including a target application, and the target application is used in an operating system corresponding to the created second differencing VHD file.
The second differencing VHD file is created using the target first differencing VHD file as a master, and when the terminal device 100 restarts using the second differencing VHD file as a system disk, an operating system is loaded from the target first differencing VHD file, and then data in the second differencing VHD file is loaded. In the case where the second differencing VHD file is created and not modified, no content is stored thereon, so the operating system launched from the second differencing VHD file at this time is consistent with the operating system launched from the target first differencing VHD file. However, after the operating system is started from the second differencing VHD file, all operations and modifications on the current operating system are retained in the second differencing VHD file without affecting the target first differencing VHD file.
Therefore, the restoration of the target first differencing VHD file can be achieved only by deleting the second differencing VHD file when it is no longer in use.
After determining the target first differencing VHD file, whether a second differencing VHD file to be used as a system boot disk needs to be created may be determined in different ways depending on application scenarios.
In one case, since the storage space of the terminal device 100 is limited, it is simultaneously available to only one user for each different application or for each different course. In this case, when the terminal device 100 receives a selection instruction, only one second differencing VHD file may be available for the target first differencing VHD file corresponding to the selection instruction. In this embodiment, a second differencing VHD file created based on the target first differencing VHD file needs to be used as a system boot disk.
Therefore, after determining the target first differencing VHD file corresponding to the received selecting instruction, the terminal device 100 may determine whether it is necessary to create a corresponding second differencing VHD file directly according to whether there is a second differencing VHD file created based on the target first differencing VHD file through step S302.
Step S303, associating the second differencing VHD file with the boot configuration of the terminal device 100, so that the terminal device 100 boots an operating system from the second differencing VHD file when rebooting, and saves data generated by an operation performed on the operating system in the second differencing VHD file.
When a second differencing VHD file created on the basis of the target first differencing VHD file (master) exists in the terminal device 100, the second differencing VHD file is directly associated with the boot configuration of the terminal device 100, that is, the second differencing VHD file is directly set as a system boot disk.
In detail, the Boot Configuration Data (BCD) of the terminal device 100 includes a system Boot list, and in a normal case, a system Boot item of a native operating system of the terminal device 100 is set in the system Boot list, and the system Boot item of the native operating system is usually a default Boot item. The native operating system refers to an operating system that is pre-installed on a physical disk of the terminal device 100.
In this embodiment, when the second differencing VHD file created using the target first differencing VHD file as the master exists in the terminal device 100, a system startup item may be newly created in the system startup list as a system startup item of the second differencing VHD file, and the system startup item may be set as a default startup item. Thus, after the terminal device 100 is restarted, the operating system corresponding to the second differencing VHD file can be entered. In detail, when the terminal device 100 is restarted, it is started with the operating system in the master of the second differencing VHD file, but data resulting from operations performed on the restarted operating system is stored in the second differencing VHD file. Accordingly, modifications and operations to the target application are stored in the second differencing VHD file.
Optionally, the operating system switching method may further include step S304.
Step S304 is to create a second differencing VHD file, and associate the created second differencing VHD with the start-up configuration of the terminal device 100.
Wherein the second differencing VHD file created with the target first differencing VHD file as a master is absent in the terminal device 100 in the following cases:
first, a user uses a target application on the terminal device 100 for the first time, and thus does not create a second differencing VHD file taking the target first differencing VHD file as a master;
secondly, the user performs a restore operation after using the target application program on the terminal device 100 last time, that is, the second differencing VHD file created by the user before and using the target first differencing VHD file as the master disk is already deleted.
When the two situations occur, the terminal device 100 creates a second differencing VHD file using the target first differencing VHD file as a master disk, and then sets the created second differencing VHD file as a system boot disk, so that the terminal device 100 runs an operating system corresponding to the second differencing VHD file after being restarted.
When the terminal device 100 is used by a user in a teaching process, the terminal device 100 needs to communicate with other terminal devices 100 (hereinafter referred to as "peer devices"), such as an application scenario shown in fig. 2, and a terminal device a and a terminal device B need to be connected to each other for communication. The terminal device 100 may communicate with a client in the peer device through the client, and the terminal device 100 may also communicate with a browser in the peer device through the browser. At this time, the terminal device 100 needs to obtain current user configuration information to notify the identity of the peer device, so as to establish a communication connection with the peer device. Correspondingly, the target application program further comprises the client or the browser.
The user configuration information at least may include terminal configuration information and/or user identity information, where the terminal configuration information refers to basic configuration information required for the terminal device 100 to communicate with the other terminal devices 100, and may include identification information (e.g., number information, identification code, etc.) of the terminal device 100, and the terminal configuration information may be determined according to an actual situation; the user identity information may include an identity (e.g., an identity number, a user name, etc.) of the user and password information corresponding to the identity.
In a specific embodiment, after the operating system corresponding to the second differencing VHD file is started, the user may re-input the user configuration information on a web page in the client or browser therein.
In another specific embodiment, before the step of associating the created second differencing VHD file with the start-up configuration of the terminal device 100 in step S304 is performed, the operating system switching method may further include the steps of:
acquiring current user configuration information of the terminal device 100, and writing the user configuration information into the created second differencing VHD file.
The user configuration information includes basic configuration information required for operating a corresponding client or browser and current user identity information, where the user identity information may specifically include a user name of a current user and a password corresponding to the user name. Alternatively, when in a one-to-many teaching scenario, for example, in the case of one lecturer with multiple learners, the multiple learners may be generally numbered by class or classroom, and accordingly, the user identity information may further include classroom numbers.
Alternatively, the user configuration information may be written to a preset location of the created second differencing VHD file, for example, a user _ data folder or the like. In this way, the terminal device 100 is convenient to acquire the user configuration information after starting the created second differencing VHD file as a system disk.
Through the above process, after the terminal device 100 starts up with the second differencing VHD file as the system disk, it is able to run the corresponding client (or browser) through the user configuration information stored in the second differencing VHD file, and further establish a communication connection with the client (or browser) of the peer device.
Regarding the manner of determining whether or not it is necessary to create the second differencing VHD file serving as the system-booted disk, in another case, when the storage space of the terminal device 100 is sufficient, it is available to a plurality of users at the same time for each different application or for each different course. In this case, when the terminal device 100 receives a selection instruction, the target first differencing VHD file corresponding to the selection instruction may have a plurality of second differencing VHD files. At this time, the plurality of second differencing VHD files need to be distinguished. In detail, the terminal device 100 may determine whether the corresponding second differencing VHD file needs to be created through step S402 shown in fig. 4, which is described in detail below.
Step S402, searching for a second differential VHD file created based on the target first differential VHD file in the terminal device 100, acquiring current user configuration information of the terminal device 100 when the second differential VHD file is found, and determining whether the target second differential VHD file storing the user configuration information exists in the searched second differential VHD file. If yes, go to step S403; if not, step S404 may be performed.
Wherein the target second differencing VHD file is one of the found second differencing VHD files, which means: and storing the second differencing VHD file of the user configuration information in a second differencing VHD file created by taking the target first differencing VHD file as a master disk.
Step S403, associating the target second differencing VHD file with the boot configuration of the terminal device 100, so that the terminal device 100 boots an operating system from the target second differencing VHD file when rebooting, and saves data generated by an operation performed on the operating system in the target second differencing VHD file.
When the target second differencing VHD file exists in the terminal device 100, the terminal device 100 sets the target second differencing VHD file as a system boot disk.
Further, in an actual application, the target second differencing VHD file may not exist in the terminal device 100, and at this time, step S404 shown in fig. 4 may be performed.
Step S404 of creating a second differencing VHD file based on the target first differencing VHD file, and storing the user configuration information in the created second differencing VHD file, thereby obtaining the target second differencing VHD file; associating the target second differencing VHD file with a start-up configuration of the terminal device 100.
In this way, each second differencing VHD file includes user configuration information of a corresponding user, and when a selection instruction is received, the identity of the current user can be determined according to the current user configuration information of the terminal device 100, and then the second differencing VHD file corresponding to the current user is determined to be used as a target second differencing VHD file, so that a plurality of users can be supported to use different target application programs on the terminal device 100 without interfering with each other.
Optionally, after associating the second differencing VHD file with the start-up configuration of the terminal device 100, that is, after performing any one of step S303, step S304, step S403, and step S404, the operating system switching method may further include the steps of:
restarting the terminal device 100;
after the terminal device 100 is restarted, the user configuration information stored in the current system disk is acquired, and a communication connection is established with an external terminal through the user configuration information.
Therefore, the lecturer can manage the client side (or the service on the browser) of the learner, and the course can be smoothly carried out.
Alternatively, when the user no longer uses the target application or after a lesson, it is often necessary to revert back to the native operating system. Therefore, after restarting the terminal device 100, the operating system switching method may further include the steps of:
the native operating system of the terminal device 100 is set as the default boot system.
The native os is an os installed on a physical disk of the terminal device 100, and each os started from the VHD file is actually an os installed on a VHD file in a physical disk of the terminal device 100 and belongs to a virtual os. In implementation, the system startup item of each VHD file in the system startup list of the terminal device 100 may be deleted, and then the system startup item of the native operating system may be set as a default startup item, so that the native operating system of the terminal device 100 is set as a default startup system.
Thus, after the user finishes using the target application program or takes a class, the user can directly restart the terminal device 100, and then return to the native operating system.
In order to facilitate the use of the user later, the operating system switching method may further include the steps of:
and after the native operating system is started, receiving a reduction instruction, and deleting a second difference VHD file corresponding to the reduction instruction.
The restore instruction refers to an instruction for deleting the second differencing VHD file, and the restore instruction may include the following two types:
first, when the terminal device 100 detects an operation of deleting a specified second differencing VHD file by a user, a deletion instruction (restore instruction) for deleting the specified second differencing VHD file may be generated.
Secondly, when the terminal device 100 is a terminal for teaching, when the terminal device 100 creates each second differencing VHD file, the attribute information of the course corresponding to the second differencing VHD file may be recorded, for example, the number of classes that need to be used for the course, and when the number of classes that need to be used for the course is multiple, the reduction needs to be performed. In this way, the terminal device 100 may determine whether the second differencing VHD file needs to be deleted according to the attribute of the course corresponding to each second differencing VHD file, and generate a restoring instruction corresponding to the second differencing VHD file when deletion is required.
