detailed description

The embodiments of the present invention are further described in detail with reference to the accompanying drawings, in which FIG. An exhaustive example. And in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

The inventor noticed during the invention:

In the implementation manner of the existing virtual machine function service, for a certain type of function service, the client and the server end are in one-to-one correspondence. As the types of functional services increase, the number of servers increases exponentially, which affects the stability, reliability, and management efficiency of system resources.

Based on this, the present invention provides a method for implementing a virtual machine function service, and a method for implementing the virtual machine function service, each client virtual machine can send a corresponding function service request to the main operating system, so that the main operating system call is used for The server-side software that provides the corresponding operating system function processes the function service request, and is mainly used to reduce the impact of the virtual machine function service on the performance of the embedded system.

The present invention provides a method for implementing a virtual machine function service, which is applied to an implementation system of a virtual machine function service shown in FIG. 1. The system includes a main operating system 101, and the main operating system 101 runs n. a virtual machine 103, wherein one primary virtual machine and n-1 client virtual machines, each client virtual machine running a client operating system 102, n is greater than or equal to An integer of 1. The client virtual machine is the virtual machine where the client operating system is located, and the primary virtual machine is the virtual machine where the operating system is located.

The main operating system 101 provides m types of functional services such as a processor management function service, a memory management function service, a device management function service, a file system management function service, and an interface function service, and m is an integer greater than or equal to 1.

The virtual machine function service implements the system startup process, as shown in FIG. 2 .

201. After the main operating system 101 is started, the m server ends are sequentially started.

Each server side corresponds to one type of functional service.

202. After the main operating system 101 starts the m server ends, the n client operating systems 102 are sequentially started.

203. In the main operating system 101, when it is detected that the client operating system 102 is started, the process corresponding to the server software is started for the client operating system 102.

After any client operating system 102 is started, m clients are sequentially started, and a connection with the server is established through a process corresponding to the server software;

Among them, each client corresponds to one type of functional service. The client has the same functional service type as the corresponding server.

After step 201 and step 202, m server ends are started on the main operating system 101, and each server end corresponds to one type of functional service. Each client operating system 102 starts m clients, and each client also corresponds to one type of functional service. At the same time, the server end corresponding to the same type of function service establishes a connection with the client through the process corresponding to the server software. For any of the m types of functional services A, each host operating system 101 starts a unique server end corresponding to the functional service A, and each client operating system 102 also starts corresponding to the functional service A. The only server side, but because there are n client operating systems, for functional service A, its corresponding server side and its corresponding client are one-to-many relationship.

FIG. 3 shows the connection relationship between the client and the server in the implementation system of the virtual machine function service when m=2 and n=3.

The main operating system 101 runs four virtual machines 103, which are a primary virtual machine, a client virtual machine A, a client virtual machine B, and a client virtual machine C. Each client VM 102 runs a client operating system 102, that is, the virtual machine A runs the client operating system A, the virtual machine B runs the client operating system B, and the virtual machine C runs the client operating system C. The main operating system 101 can provide the function service A and the function service B. Therefore, the main operating system 101 starts two server ends, which are respectively the server A of the corresponding function service A and the server B of the function service B. Two clients are started on each client operating system 102. For example, the client A is activated on the client operating system A, the client A is corresponding to the function service B, and the client AB is activated on the client operating system B. The client BA of the service A, the client BB of the corresponding function service B, and the client CA of the corresponding function service A and the client CB of the corresponding function service B are activated on the client operating system C. After performing step 201 to step 203, six connections are established, which are respectively three connections corresponding to function service A (LAA between server A and client AA, LAB between server A and client BA, server) LAC between the end A and the client CA, corresponding to the three connections of the function service B (the LBA between the server B and the client AB, the LLB between the server B and the client BB, the server B and the client LBC between end CBs).

204. In the client operating system 102, when the request for the preset operating system function is monitored, the corresponding virtual service 103 is sent to the primary virtual machine 103 by the client virtual machine 103.

The main operating system 101 establishes and maintains the context of each connection. The context information generated for presetting the operating system function is transmitted to the primary virtual machine 103 through the client virtual machine 103.

The context of the connection includes, but is not limited to, the environment at the time of connection execution, such as various variables and data.

The context of the connection is dynamically updated as the connection changes in real time, ie maintenance.

In the actual application process, the configurations of different client virtual machines 103 are different, and the types of functional services provided by the main operating system 101 are required to be different. Even if different client virtual machines 103 require the main operating system 101 to provide the same kind of functional services, the parameters and the like involved in the functional services are different. Therefore, after performing steps 201 to 204 to establish a connection between the server in the main operating system 101 and the client in the client operating system 102 running in the client virtual machine 103, it is necessary to establish the connection for all kinds of connections. The connection is processed to disconnect the connection corresponding to the functional service provided by the host operating system 101 for the client virtual machine 103, destroy the context of the connection, release resources, and reduce the number of maintenance of the connection.

205. In the main operating system 101, after monitoring that the primary virtual machine 103 receives the function service request, the server software for providing the corresponding operating system function is invoked to process the function service application, and then the processed result is returned to the Client virtual machine 103.

Specifically, the received context information is processed by using a process corresponding to the function service request.

206. After receiving the processing result returned by the main virtual machine 103, the client operating system 102 returns the processing result to the requester of the preset operating system function.

Taking the connection situation of FIG. 3 as an example, if the client operating system C sends the function service request of the corresponding function service A to the main virtual machine 103 through the client virtual machine 103 in step 204, the main operating system 101 calls in step 206. The server-side software for providing the corresponding operating system function processes the function service A application, that is, in the two connections (LAC and LBC) established by the main operating system 101 and the client operating system C, the client CA corresponding to the LAC is corresponding. The functional service A is a functional service provided by the main operating system 101 to the client operating system C. According to the received context information, the function service application corresponding to the function service application of the function service A is processed, as shown in FIG. 4 .

After performing step 203, the main operating system 101 also allocates a state lock for the corresponding process of the function service request, and the state lock is used to make the process run. At the same time, the preset function is monitored. When the service is stopped, the state lock is released.

After the step 205 is performed, in the main operating system 101, when the preset function service stop condition is monitored, the process of the corresponding server-side software is stopped. For example, after stopping the process of the corresponding server-side software, the context information is destroyed.

Among them, the preset function service stop condition is any one of the following:

Condition 1: The client virtual machine is detected to be in a running state in the main operating system;

Condition 2: In the main operating system, it is monitored that the client operating system is in a sleep state;

Condition 3: In the main operating system, detecting the function service stop request sent by the client virtual machine: At this time, the method further includes: in the client operating system, when monitoring the request for stopping the preset operating system function, The application is stopped by sending a corresponding function service to the primary virtual machine through the client virtual machine.

Through the flow shown in FIG. 2, the server side in the main operating system 101 establishes a connection with the client in the client operating system 102. After the connection is established, the server can provide functional services for the connected client, including the following three aspects: 1) obtaining the service list; 2) enabling the service; 3) stopping the service.

● For the function service of obtaining the service list, as shown in Figure 5.

501. Any client operating system 102 sends an application for obtaining a service list to the main operating system 101.

502. The host operating system 101 sends a list of functional services provided by any of the client operating systems 102 to any of the client operating systems 102.

Taking the connection situation shown in FIG. 4 as an example, the client operating system C sends an application for obtaining a service list to the main operating system 101. The main operating system 101 sends a specific list of functional services A provided to the client operating system C to the client operating system C.

● For the functional services of the enabled service, as shown in Figure 6.

601, any client in any of the client operating systems 102 sends to the host operating system 101 Application for functional services.

602. The main operating system 101 determines that the virtual machine 103 where any of the client operating systems 102 is located is in an active state, and provides functional services to any client through the corresponding server.

Taking the connection situation shown in FIG. 4 as an example, the client CA in the client operating system C sends an application for the function service to the main operating system 101, and the main operating system 101 determines that the virtual machine C where the client operating system C is located is active. , through the server A to provide functional services to the client CA.

● For the functional service of stopping the service, as shown in Figure 7.

701. The client operating system 102 sends an application to stop the service to the main operating system 101.

702. The main operating system 101 destroys context information.

Still taking the connection situation shown in FIG. 4 as an example, the client operating system B corresponding to the client BA of the LAB sends an application to stop the service to the main operating system 101, and the main operating system 101 destroys the context information.
