The cloud operating system is deployed in a container of each server operating system of the server cluster. Fig. 1 is a schematic diagram of a server cluster according to an embodiment of the present application, and as shown in fig. 1, servers in the server cluster are connected in a star distribution via TCP and record a user list. It should be noted that the number of servers in the figure is schematic. The server is provided with a record table of the corresponding IP and performance of the server, the record table comprises user information corresponding to a user list on each server virtual machine, the user information comprises user operation files and application program data on the virtual machines, and the record table is periodically synchronized, so that the timeliness of data synchronization on the virtual machines and the server can be improved.
The embodiment provides a virtual machine control method of a cloud operating system, fig. 2 is a flowchart of the virtual machine control method of the cloud operating system according to the embodiment of the application, and fig. 3 is an interaction schematic diagram of the virtual machine control method according to the embodiment of the application. As shown in fig. 2 and fig. 3, the process includes the following steps:
s210, the client sends a virtual machine request instruction to request for establishing the virtual machine.
S220, when the load balancing module receives the virtual machine request instruction, a first server with a hardware load smaller than a preset threshold value in the server cluster is searched, and a first virtual machine configured corresponding to the virtual machine request instruction is generated. The first virtual machine has a configuration corresponding to the request virtual machine instruction and imports a user information record of the client. The first server is an empty server or a server with a hardware load smaller than a preset threshold, namely the first server has enough resources to establish the virtual machine. Preferably, the server which is empty is preferentially searched as the first server, so that the first server can be used for a longer time, the migration time is delayed, the overall migration times of the virtual machines on the server cluster are reduced, and the efficiency is better.
And S230, returning the first virtual machine to the client.
S240, the client is connected with the first virtual machine for the first time. The virtual machine is generated on the first server with enough resources, so that the command sent by the client can be ensured to be responded quickly, and the user experience is improved.
Preferably, the cloud operating system periodically saves the user operation file on the first virtual machine at regular time, and backs up the user operation file on the first virtual machine to the first operating system. For example, the state of each server is synchronized once every 30 seconds, so that when a client has a connection request, the currently vacant server is preferentially inquired in the record table for distribution, and the hardware load of the server cluster is balanced. And the timeliness of data synchronization of the virtual machine and the server is ensured.
The embodiment provides a virtual machine control method for saving the state of a virtual machine. Fig. 4 is an interaction diagram of a virtual machine control method for saving a virtual machine state according to an embodiment of the present application, where as shown in fig. 4, a client connects with a first server and establishes a user list. The client presents an application instruction to the first virtual machine requesting addition or deletion of an application. And the first virtual machine responds to the application instruction, performs corresponding operation of adding or deleting the application, and synchronously stores the application program data of the corresponding operation to the first operating system so as to realize the application program data synchronization of the virtual machine and the server, and the server stores relevant information such as software list records and the like. When the cloud data is stored, the data is stored in the server instead of the virtual machine, so that when a client makes a connection request, the cloud operating system can allocate any operating system to the client, and simultaneously import user information such as user operating files, application program data and the like. And the cloud operating system monitors the service condition of the server cluster hardware, and if the load of certain server hardware exceeds a preset threshold, the cloud operating system automatically sends the request and the user information sent by the client to other servers with hardware loads smaller than the preset threshold or even vacant, so that the load balance of the server cluster can be achieved.
In order to improve capacity expansion efficiency and solve the problem of difficult capacity expansion, an embodiment of the present application provides a method for controlling a virtual machine of a cloud operating system for capacity expansion, where a client sends a configuration instruction requesting to upgrade or reduce configuration of the operating system, and when receiving the configuration instruction, the cloud operating system dynamically generates an operating system matched with the configuration instruction and imports a client configuration file into the operating system.
The present embodiment provides another method for controlling a virtual machine of a cloud operating system, fig. 5 is a flowchart of another method for controlling a virtual machine of a cloud operating system according to an embodiment of the present application, and fig. 6 is an interaction diagram of a case where a first server resource is fully loaded according to an embodiment of the present application. As shown in fig. 5 and fig. 6, the process includes the following steps:
s510, the client is not connected with the first virtual machine generated by the first server for the first time.
S520, the client sends a request server resource to the first server.
S530, when the first server receives the request server resource sent by the client, whether the hardware load of the first server exceeds a preset threshold value is judged.
And S540, if the hardware load of the first server exceeds the preset threshold, the cloud operating system searches a second server in the server cluster, wherein the hardware load of the second server is smaller than the preset threshold. Illustratively, in this embodiment, the server cluster further includes a second server, a third server, and a fourth server. In practice a server cluster may also comprise more servers. Preferably, the server with the empty space is preferentially searched as the second server, so that the hardware load of each server in the server cluster can be more balanced. If the server resources of the first server are full, calling a second server with the least resource utilization rate in the server cluster.
And S550, creating a second virtual machine on the second server, and importing the user information of the first virtual machine.
And S560, returning the second virtual machine to the client. The second virtual machine responds to the client with the data.
And S570, if the hardware load of the first server is smaller than a preset threshold, the client which is not logged in for the first time allocates the generated first virtual machine resource.
When the hardware resources of the first server are sufficient, the client which is not logged in for the first time can directly allocate the resources of the first virtual machine. When the hardware resources of the first server are insufficient, the user information of the first virtual machine is stored in the server cluster, so that the user information of the virtual machine can be quickly migrated under the condition of not reinstalling software, the user information cannot be lost, the quick migration of the virtual machine is realized on the server cluster, any virtual machine can be a virtual machine responding to the requirements of a client side in a short time, and meanwhile, the load balance of the virtual machines on all servers is considered through the communication among the servers.
Fig. 7 is a timing diagram illustrating the interaction between the client and the virtual machine and the server, and as shown in fig. 7, the message flow of the request information initiated by the client in the virtual machine and the server under different scenarios is shown. When the client requests to add or delete an application, the virtual machine performs a corresponding operation and synchronizes information to the server 1. When a client requests a virtual machine, the server 1 has enough resources, the server 1 generates the virtual machine and imports user information, the virtual machine is returned to the client, and the client is connected with the virtual machine generated by the server 1 for the first time. The client is not connected with the virtual machine generated by the server 1 for the first time and requests resources for the server 1, when the hardware load of the server 1 exceeds a preset threshold value, the server 2 with low load (the load is smaller than the preset threshold value) is searched, user information is sent to the server 2, the server 2 generates the virtual machine and imports the user information, and the virtual machine is returned to the client. By synchronizing the data of the virtual machine and the server, a user can quickly create an own operating system by using any virtual machine in a short time, and the problem of difficult migration of the virtual machine is solved. Meanwhile, through the communication among the servers, the load of the virtual machines on the servers of the server cluster can be balanced.

9. The virtual machine control device according to claim 8, wherein the device further comprises a load balancing module, a virtual machine generation module, a data synchronization module and a capacity expansion module;
the load balancing module is used for searching a first server in the server cluster, wherein the hardware load of the first server is smaller than the preset threshold value when the load balancing module receives a virtual machine request instruction sent by the client;
the virtual machine generation module is used for generating a first virtual machine configured corresponding to the request virtual machine instruction and returning the first virtual machine to the client so that the client is connected with the first virtual machine for the first time;
the data synchronization module is used for periodically saving the user operation files on the first virtual machine and backing up the user operation files on the first virtual machine to the first operating system;
and the capacity expansion module is used for dynamically generating an operating system matched with the configuration instruction and importing a client configuration file when receiving the configuration instruction which is sent by the client and requests upgrading or degrading the operating system configuration.
10. A computer-readable storage medium on which a computer program is stored, wherein the program, when executed by a processor, implements the virtual machine control method according to any one of claims 1 to 7.
