Detailed ways

As shown in FIG. 1 , it is a schematic diagram of the application environment of the control computer of the present invention. In this embodiment, the control computer 2 is connected to a plurality of client computers 5 through a network 4 and connected to a database 3 through a database connection. The network 4 can be an intranet, the Internet or other types of communication networks, such as GPRS, Wi-Fi/WLAN, 3G/WCDMA, 3.5G/HSDPA, etc.

The control computer 2 is used to send a control command to the client computer 5, and obtain virtual machine (Virtual Machine, VM) information from the database 3 or the client computer 5 according to the type of the control command.

The database 3 is used to store data of each virtual machine on the client computer 5 and user-defined data. Wherein, the virtual machine information includes, but is not limited to, the name of the virtual machine, an identifier (Identifier, ID), an operating system (Operating System, OS) used, and remark information. The user-defined data is a user-defined folder for storing identifiers and description information of the client computer. For example, the user can store the identifiers and description information of the client computers Host1, Host2, Host3, Host4, and Host5 in Folder 1 (such as Folder 1), and store the identifiers of the client computers Host6, Host7, Host8, Host9, and Host10 and description information are stored in folder 2 (such as Folder2) to facilitate the management of the client computer.

Referring to FIG. 2 , the control computer 2 includes a display device 20 , an input device 22 , a memory 23 , a virtual machine management system 24 and a processor 25 connected through a data bus.

The memory 23 is used to store data such as program codes of the virtual machine management system 24 . The display device 20 is used for displaying virtual machine data of the client computer 5 and the like. The input device 22 is used to input various data set by the user, such as description information of the client computer and the like.

The virtual machine management system 24 is used to send a control command to the client computer 5, and obtain virtual machine data from the database 3 or the client computer 5 according to the type of the control command. The specific process is described below.

In this embodiment, the virtual machine management system 24 can be divided into one or more modules, and the one or more modules are stored in the memory 23 and configured to be executed by one or more processors ( This embodiment is executed by one processor 25) to complete the present invention. For example, referring to FIG. 3 , the virtual machine management system 24 is divided into an instruction sending module 201 , an instruction judging module 202 , a data acquisition module 203 and a data update module 204 . The module referred to in the present invention is a program segment that completes a specific function, and is more suitable for describing the execution process of software in the control computer 2 than a program.

As shown in FIG. 4 , it is a flow chart of a preferred embodiment of the virtual machine management method of the present invention.

Step S10 , the instruction sending module 201 issues a control instruction to the client computer 5 .

In step S11, the instruction judging module 202 judges the type of the control instruction. In this embodiment, the types of the control instructions include the first type and the second type. Wherein, the first type of control instruction refers to querying or updating virtual machine information that does not change frequently, such as the name of the virtual machine. The second type of control instruction refers to querying virtual machine information that changes at any time, such as the CPU utilization rate of the virtual machine. If the type of the control instruction is the first type, execute steps S21-S25; if the type of the control instruction is the second type, execute steps S31-S33.

Step S21, if the type of the control instruction is the first type, the instruction judging module 202 judges whether the control instruction is to query virtual machine information or update virtual machine information. If the control instruction is to query virtual machine data, then execute step S22; if the control instruction is to update virtual machine information, then execute step S23.

In step S22, the data obtaining module 203 directly obtains the first type virtual machine data (such as the name of the virtual machine) of the client computer 5 from the database 3, and then executes step S25. In this embodiment, the first type of virtual machine information is virtual machine information that does not change frequently, such as the name of the virtual machine. Since the virtual machine data of the first type can be directly read from the database 3, the time for obtaining the virtual machine data of the client computer 5 can be accelerated, and the instruction operations on the client computer 5 can be reduced.

In step S23, the command sending module 201 transmits the first type of control command to a virtual machine management program (such as a Hypervisor program) of the client computer 5 to execute the control command. The virtual machine management program of the client computer 5 updates the virtual machine information (such as the name of the virtual machine) of the client computer 5 according to the first type control command, and sends the updated virtual machine information to the control computer 2 .

In step S24, the data obtaining module 203 obtains the updated virtual machine data returned by the virtual machine hypervisor of the client computer 5 . Then, the data update module 204 updates the corresponding virtual machine data in the database 3 according to the updated virtual machine data.

In step S25, the data obtaining module 203 obtains the execution result of the first type of control instruction. In this embodiment, the execution result of the first type of control instruction includes execution success or execution failure. For example, if step 22 fails to obtain the name of the virtual machine of the client computer 5 from the database 3, the execution result is that the name query fails. If updating the name of the virtual machine in the database 3 fails in step S24, the execution result is that updating the name fails.

Step S31 , if the type of the control instruction is the second type, the instruction sending module 201 transmits the second type of control instruction to the hypervisor of the client computer 5 to execute the control instruction. The virtual machine management program of the client computer 5 obtains the second type of virtual machine data (such as the CPU usage rate of the virtual machine) according to the control command, and transmits the obtained virtual machine data to the control computer 2 . In this embodiment, the second type of virtual machine data is virtual machine data that changes at any time, such as the CPU usage of the virtual machine.

In step S32, the data obtaining module 203 obtains the data of the second-type virtual machine returned by the virtual machine hypervisor of the client computer 5 . In this embodiment, since the information of the second type virtual machine may change at any time, it will not be stored in the database 3 .

In step S33, the data obtaining module 203 obtains the execution result of the second type of control instruction. In this embodiment, the execution result of the second type of control instruction includes execution success or execution failure. For example, if step 32 fails to obtain the CPU usage of the virtual machine, the execution result is that querying the CPU usage fails.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention without limitation. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be Modifications or equivalent replacements can be made without departing from the spirit and scope of the technical solutions of the present invention.
