An interface is arranged between the management center 110 and the storage node 120 for information interaction. An interface is arranged between the management center 110 and the operation node 130 for information interaction.
In some embodiments, the management center 110 selects the operational node of the service according to at least one of the distance of the operational node 130 from the user, the network quality, and the support capability for the service of the user.
The storage node 120 is configured to query a progress file corresponding to a service of a user according to the progress query instruction, and send the progress file to the service operation node 130.
In some embodiments, in the case that the storage node 120 includes a plurality of storage nodes and there are a plurality of storage nodes that all store the progress file of the service of the user, the management center 110 may select a storage node 120 according to at least one of a distance between the storage node 120 and the user and a network quality, and send the query instruction to the selected storage node 120 in parallel.

The operation node 130 is configured to load the progress file in response to receiving the progress file, construct a virtual environment, and operate the service.
An interface is arranged between the storage node 120 and the operation node 130 for information interaction. After receiving the progress file and the operation instruction of the management center 130, the operation node loads the progress file and constructs a virtual environment. Under the condition of no progress file, the operation node 130 responds to the operation instruction of the management center 130 to directly construct a virtual environment and operate the service.

The management center is responsible for distributing operation nodes for the users according to the requests of the users, the storage nodes store progress files of the users, and the operation nodes are responsible for constructing virtual environments according to the progress files, so that operation of services is realized, and the last-time use conditions of the users can be seamlessly docked. Different operation nodes can realize the construction of the virtual environment and provide services for users. Compared with a single machine mechanism and a data strong isolation mechanism which are stored and operated in a container and are positioned in the same container, the mechanism of separating the storage node, the operation node and the management center in the embodiment can realize flexible deployment of services and meet service requirements of users in real time.
In addition, the mechanism of separating the storage node, the operation node and the management center in the above embodiment can effectively support linear expansion, and flexibly add the operation node and the storage node. The multiple operation nodes support high concurrency of services, and the carrying capacity of the cloud is improved. Compared with a single machine mechanism and a data strong isolation mechanism of the container, the scheme of the embodiment can also reduce the occupation of hardware resources, and further improve the carrying capacity of the cloud.

For storage management, the management center 110 implements functions including, for example, storage node monitoring, storage node scheduling, association of users with storage nodes, and the like. In the case that the storage node 120 includes a plurality of storage nodes, the management center 110 may monitor the plurality of storage nodes 120, schedule one storage node 120 for a user among the plurality of storage nodes 120 to query the progress file of the user, or send a progress query instruction to the storage node 120 associated with the user and a service.
The storage node 120 may implement a function of storing service progress based on two-dimensional mapping of users and services. The storage node 120 may provide scheduling functions to store services and schedule files, etc. For the storage service, the storage node 120 provides a function of storing a plurality of progress files of a plurality of virtual environments according to an instruction of the management center. Aiming at scheduling of the progress files, the storage node 120 realizes the scheduling function aiming at different progress files according to the association relation between users and services, and transmits the corresponding progress files to corresponding operation nodes in real time according to the query instruction of the management center.

For the process file import, the operation node 130 may import the process file corresponding to the service of the user into the corresponding virtual operation environment, so as to implement seamless docking of the last use condition of the user. For the input takeover, the operation node 130 can effectively intercept the input operation of the user for the service, including instructions such as a hard disk/a mouse, a handle and the like, shield the limitation of uniqueness of the operation node for external input, and effectively transmit the limitation to the corresponding virtual environment. The output takeover operation node 130 can intercept output results of information such as images and audio in the user service operation process, reduce consumption of software and hardware, and support remote output based on video streams or other modes.
In some embodiments, the operation node 130 is configured to intercept input information of the service from a user, and send the input information to a corresponding virtual environment, so as to operate the service according to the input information. In some embodiments, the operation node 130 is further configured to intercept output information generated during operation of the service, and send the output information to a client of a user for output. The running node may implement the takeover of input/output using operating system level API Hook (application interface hooking) technology. The API Hook technology is suitable for various operating systems, and compared with the problem that the container technology is limited in the application of the operating systems, the scheme disclosed by the invention has wider applicability.
In some embodiments, the running node 130 is further configured to update the progress file of the service, send the progress file to the corresponding storage node 120 for storage, and delete the progress file in the running node 130, so as to save storage space and avoid data confusion when other users use the same service.
The operation node 130 serves as a main service execution subject in the virtualization management system, and the structure diagram is shown in fig. 3. The runtime node 130 may be configured with a plurality of virtual environments, which mainly include a hardware component and a software component. The hardware environment comprises: hardware execution environments such as a CPU, a GPU (graphics processing unit), and the like. The software part comprises a monitoring and capturing function, an operating environment, an external interface and the like. The interception and capture function is to intercept and intercept the input information and the corresponding output information of the user, i.e. input/output take-over. The output takeover includes API HOOK takeover of graphics output and audio output such as DirectX, OpenGL (open graphics library). The input takeover comprises handle input such as DirectInput, XINPUt, RawInput, USB input, keyboard input API HOOK takeover and the like.
And running the corresponding application based on the multithreading mode of the operating system in the running environment. In some embodiments, where the service includes graphics rendering, the virtual environment in the run-time node 130 invokes the graphics processor in the form of an operating system thread to render the image in the service. The scheme disclosed by the invention supports the effective calling of the GPU, and can realize the rendering and processing of complex images relative to the deficiency of the calling capability of a container mechanism to the GPU.
The external interface of the operation node 130 includes: a run interface and a storage interface. And the operation interface can be in butt joint with the management center to realize the starting of the virtual operation environment according to the requirement. When the service is started, the storage interface can import the progress file of the storage node into the operation node according to the instruction of the management center; when the service is terminated, updating and storing the user service progress, saving the corresponding storage progress file to the storage node, and deleting the local storage.
The virtualization management system is suitable for internet cloud services with multiple concurrent services and low data isolation requirements, and solves the problem that the container technology cannot run or the cloud performance is reduced in the running process. By adopting a separation mechanism of the storage node, the operation node and the management center, flexible service deployment can be met, the operation and storage capacity can be effectively expanded according to the service bearing requirement, the overall bearing capacity is increased, and the cost of concurrent users is effectively reduced. And the virtualization management system disclosed by the invention is simple in structure and easy to realize.
According to the method, a complete simple cloud virtual mechanism for self-adaptive service requirements is constructed from two aspects of virtual environment management and individual virtual environment operation, the problems of operating system and GPU (graphics processing unit) computing capability support limitation under a Docker mechanism and native API hook mechanism localization limitation are solved, environment relative isolation can be achieved, and occupation of resources can be effectively reduced.
The method is constructed by adopting an API Hook mechanism, and has the widest support capability of an operating system, including main stream systems such as linux, windows and Android and various versions. The virtual environment is operated in a system thread mode, so that more software and hardware resources and capabilities of the cloud server are not required to be consumed, and the bearing capacity of the application can be effectively improved. Based on a calling mechanism at the bottom layer of the operating system, the limitation of the Docker mechanism on GPU capability calling can be effectively solved, and the GPU can be effectively called.
