Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0036] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples.

[0037] Figure 1 A schematic diagram of the structure of a virtual machine startup system provided in an embodiment of the present application. Figure 1 The virtual machine startup method is applied to a virtual machine startup system. The virtual machine startup system includes:

[0038] The scheduling platform 110 is used to allocate a suitable target host machine to the target virtual machine upon receiving a startup instruction of the target virtual machine, and forward the startup instruction and the host machine information of the target host machine to the first host machine 120 carrying the target virtual machine, wherein the target virtual machine is any virtual machine that is free of charge when shut down.

[0039] Specifically, the scheduling platform 110 is denoted as scheduler, and can be implemented by an independent server or a server cluster composed of multiple servers. The startup instruction can be initiated by a backstage staff through a terminal to the scheduling platform 110, or by a backstage staff through a console (console) calling the communication interface (API) of the scheduling platform 110 to initiate the scheduling platform 110. The terminal can be a desktop terminal or a mobile terminal, and the mobile terminal can be at least one of a mobile phone, a tablet computer, a laptop computer, etc. In this embodiment, the console initiates a startup instruction to the scheduling platform 110 through a communication interface as an example, such as Figure 2 As shown, the start instruction includes the virtual machine identifier of the target virtual machine, which is used to request to start the target virtual machine located in the first host machine 120, indicating that the current target virtual machine is mounted on the first host machine 120 before starting, that is, the first host machine 120 is the source host machine of the target virtual machine. The scheduling platform 110 will assign a target host machine that matches the target virtual machine according to the start instruction.

[0040] The first host machine 120 is communicatively connected to the scheduling platform 110, and is used to start the target virtual machine according to the startup instruction when the target host machine is determined to be the first host machine 120 based on the virtual machine information, or to migrate the virtual machine data of the target virtual machine to the second host machine 130 when the target host machine is determined to be the second host machine 130 based on the virtual machine information, and forward the startup instruction to the second host machine 130.

[0041] Specifically, Figure 2As shown, the first host machine 120 determines whether the target host machine is the first host machine 120 based on the received host machine information. When the target host machine is the first host machine 120, the first host machine 120 directly starts the target virtual machine located locally, and can quickly start the target virtual machine without going through the cold migration process, thereby shortening the startup time of the target virtual machine, so that the target virtual machine can quickly provide data services to users. When the target host machine is not the first host machine 120 but the second host machine 130, the first host machine 120 migrates the virtual machine data of the target virtual machine to the second host machine 130, and forwards the startup instruction to the second host machine 130, but the virtual machine migration process does not require the first host machine 120 and the second host machine 130 to interact frequently, which can also shorten the migration time of the target virtual machine.

[0042] The second host machine 130 is respectively connected to the scheduling platform 110 and the first host machine 120 for communication, and is used to receive the virtual machine data and the startup instruction of the target virtual machine sent by the first host machine 120, and start the target virtual machine according to the startup instruction after the migration of the virtual machine data of the target virtual machine is completed.

[0043] Specifically, the second host machine 130 and the first host machine 120 are different host machines. When the target host machine is the second host machine 130, the second host machine 130 receives the virtual machine data and the startup instruction of the target virtual machine sent by the first host machine 120, such as Figure 2 As shown, the second host machine 130 responds to the start instruction to start the target virtual machine after the virtual machine data of the target virtual machine is migrated. Since there is no frequent interaction between the first host machine 120 and the second host machine 130 during the migration of the virtual machine data of the target virtual machine from the first host machine 120 to the second host machine 130, the migration time of the virtual machine data is shortened compared to the existing process of frequent interaction between the source host machine and the destination host machine to realize cold migration, thereby improving the startup rate of the target virtual machine to solve the problem that the startup process of the existing virtual machine that is free of charge after shutdown takes a long time.

[0044] In one embodiment, Figure 3 A flowchart of a method for starting a virtual machine in an embodiment is shown in FIG. Figure 3 , provides a virtual machine startup method. This embodiment mainly applies this method to the above Figure 1 Taking the scheduling platform 110 in the example as an example, the virtual machine startup method specifically includes the following steps:

[0045] Step S210, obtaining a startup instruction, wherein the startup instruction is used to start a target virtual machine located in the first host machine 120, and the target virtual machine is any virtual machine that is free of charge when shut down.

[0046] Specifically, the scheduling platform 110 obtains a startup instruction of the target virtual machine from the terminal or console. The target virtual machine is any virtual machine that is free of charge when shut down, indicating that the virtual machine will not generate data service fees when shut down. The target virtual machine is mounted on the first host machine 120 before being started, that is, the first host machine 120 is the source host machine of the target virtual machine.

[0047] Step S220: determining a target host machine that supports starting the target virtual machine according to the resource requirements of the target virtual machine and the available resources of each host machine.

[0048] Specifically, the scheduling platform 110 stores the virtual machine information of each virtual machine, and the virtual machine information includes the virtual machine model, the virtual machine identifier, and the resource requirements. The resource requirements include at least the storage space requirements and the processor occupancy requirements. The processor occupancy requirements are used to indicate the virtual machine's requirements for CPU occupancy. The scheduling platform 110 determines the available resources of each host machine through the host machine information regularly reported by each host machine. The parameters contained in the available resources correspond to the parameters in the resource requirements, so the available resources include at least the available storage space and the available processor occupancy. The host machine whose available resources meet the resource requirements is determined as the target host machine that supports the startup of the target virtual machine.

[0049] Step S230, sending the host information of the target host and the startup instruction to the first host 120, wherein when the host information indicates the first host 120, the first host 120 executes the startup instruction, or when the host information indicates the second host 130, after the first host 120 migrates the target virtual machine from the first host 120 to the second host 130, the second host 130 executes the startup instruction.

[0050] Specifically, when the host information of the target host indicates the first host 120, it means that the first host 120 originally carrying the target virtual machine supports starting the target virtual machine, and there is no need to perform cold migration on the target virtual machine, and the target virtual machine can be directly started on the first host 120, thereby simplifying the virtual machine startup process and accelerating the virtual machine startup efficiency; when the host information of the target host indicates the second host 130, it means that the first host 120 originally carrying the target virtual machine cannot support starting the target virtual machine, and the target virtual machine needs to be migrated to the second host 130 that supports its startup before starting, so the scheduling platform 110 sends The host information of the target host is transmitted to the first host machine 120, and the identity of the target host is determined by the first host machine 120 to decide whether to migrate the target virtual machine. When the target virtual machine needs to be migrated, the virtual machine data of the target virtual machine is migrated to the second host machine 130, and the target virtual machine is started on the second host machine 130 to complete the startup process of the target virtual machine. However, during the migration process of the above-mentioned target virtual machine, there is no need for frequent interaction between the first host machine 120 and the second host machine 130, thereby simplifying the migration process of the virtual machine and shortening the migration time of the virtual machine, thereby solving the problem that the startup process of the existing virtual machine that is free of charge when shut down takes a long time.

[0051] In one embodiment, Figure 4 As shown, the determining of the target host machine supporting the startup of the target virtual machine according to the resource requirements of the target virtual machine and the available resources of each host machine includes:

[0052] Step S221, determining a host machine whose available resources meet the resource requirements of the target virtual machine as a candidate host machine;

[0053] Step S222, when the first host machine 120 exists among the multiple candidate host machines, determine the first host machine 120 as the target host machine; or,

[0054] Step S223: when the first host machine 120 does not exist in the plurality of candidate host machines, determine the target host machine from the plurality of candidate host machines.

[0055] Specifically, a host machine whose available resources meet the resource requirements of the target virtual machine is determined as a candidate host machine. If the first host machine 120 exists among multiple candidate host machines, it means that the available resources of the first host machine 120 also meet the resource requirements of the target virtual machine. In this case, the first host machine 120 is directly selected as the target host machine. The startup instruction can be directly executed on the first host machine 120 to start the target virtual machine without the need to migrate the target virtual machine, thereby simplifying the startup process of the virtual machine.

[0056] If the first host machine 120 does not exist among the multiple candidate host machines, it means that the available resources of the first host machine 120 do not meet the resource requirements of the target virtual machine, and any one of the multiple candidate host machines can be selected as the target host machine.

[0057] In one embodiment, Figure 5 As shown, when the first host machine 120 does not exist in the plurality of candidate host machines, determining the target host machine from the plurality of candidate host machines includes:

[0058] Step S2231: when the first host machine 120 does not exist among the multiple candidate host machines, the candidate host machine with the most available resources is determined as the target host machine.

[0059] Specifically, when the available resources of the first host machine 120 do not meet the resource requirements of the target virtual machine, the candidate host machine with the most available resources is selected from multiple candidate host machines as the target host machine. The candidate host machine with the most available resources is the host machine with the least load and meets the resource requirements of the target virtual machine. Selecting the candidate host machine with the most available resources as the target host machine can balance the load on different host machines and avoid unbalanced load on each host machine due to some host machines being overloaded and some host machines being underloaded.

[0060] In one embodiment, Figure 6 As shown, a virtual machine startup method is provided, which is applied to a first host machine 120, and the method includes:

[0061] Step S310 , obtaining a start instruction issued by the scheduling platform 110 and host information of the target host machine, wherein the start instruction is used to start the target virtual machine located in the first host machine 120 .

[0062] Specifically, the host information of the target host includes at least the host identifier of the target host and the communication address of the target host. The first host 120 determines whether the target host is the first host 120 according to the host identifier in the host information, thereby deciding whether to execute the startup instruction.

[0063] Step S320, when the host information indicates that the target host is the first host 120, start the target virtual machine according to the start instruction; or,

[0064] Step S330 , when the host information indicates that the target host is the second host 130 , after sending the virtual machine data of the target virtual machine and the startup instruction to the second host 130 , the target virtual machine is started on the second host 130 .

[0065] Specifically, when the host machine identifier in the host machine information is the same as the host machine identifier of the first host machine 120, it indicates that the target host machine is the first host machine 120. Then, the first host machine 120 directly starts the target virtual machine it carries without migrating the target virtual machine, thereby simplifying the virtual machine startup process.

[0066] When the host identifier in the host information is different from the host identifier of the first host 120 and indicates the second host 130, it means that the target host is not the first host 120, and the first host 120 cannot support the startup of the target virtual machine it carries. The first host 120 sends the virtual machine data and startup instructions of the target virtual machine to the second host 130 according to the communication address in the host information, and starts the target virtual machine on the second host 130. However, the target virtual machine does not require frequent interaction between the first host 120 and the second host 130 during the migration process. Therefore, compared with the existing frequent interaction between the source host and the destination host to realize the cold migration process, the migration time of the virtual machine data is shortened, thereby improving the startup rate of the target virtual machine, so as to solve the problem that the startup process of the existing virtual machine that is free of charge when shut down takes a long time.

[0067] In one embodiment, Figure 7 As shown, when the host information indicates that the target host is the second host 130, sending the virtual machine data of the target virtual machine and the startup instruction to the second host 130 includes:

[0068] Step S331, when the host information indicates that the target host is the second host 130, migrating the configuration data of the target virtual machine from the first host 120 to the second host 130;

[0069] Step S332, obtaining the file storage type of the target virtual machine;

[0070] Step S333, when the file storage type of the target virtual machine is local storage, the storage file corresponding to the target virtual machine in the local memory of the first host machine 120 is migrated to the second host machine 130 through the intermediate database, wherein the virtual machine data includes the configuration data and the storage file; or

[0071] Step S334 , when the file storage type of the target virtual machine is cloud disk storage, redirect and mount the cloud disk storage interface corresponding to the target virtual machine from the first host machine 120 to the second host machine 130 .

[0072] Specifically, the virtual machine data at least includes configuration data and storage files. The configuration data contains basic parameters to ensure the normal operation of the virtual machine. The storage files are used to indicate the data resources used by the virtual machine to provide data services. The configuration data is usually stored in the host machine on which the virtual machine is mounted, and the storage files can be stored in the host machine on which the virtual machine is mounted, or in a cloud disk. Therefore, when migrating the virtual machine data of the target virtual machine, the configuration data of the target virtual machine is first migrated from the first host machine 120 to the second host machine 130, and then the migration method of the storage files of the target virtual machine is determined according to the file storage type of the target virtual machine. The file storage type is local storage or cloud disk storage. When the file storage type of the target virtual machine is local storage, it means that the storage files of the target virtual machine are stored in the local memory of the first host machine 120. At this time, the storage files corresponding to the target virtual machine are copied to the intermediate database, and then the storage files are copied from the intermediate database to the second host machine 130, thereby completing the migration of the storage files.

[0073] When the file storage type of the target virtual machine is cloud disk storage, it means that the storage files of the target virtual machine are stored in the cloud disk. You only need to redirect and mount the cloud disk storage interface corresponding to the target virtual machine from the first host machine 120 to the second host machine 130, so that the second host machine 130 can access the storage files corresponding to the target virtual machine through the cloud disk storage interface corresponding to the target virtual machine.

[0074] In one embodiment, Figure 8 As shown, when the host information indicates that the target host is the second host 130, after sending the virtual machine data of the target virtual machine and the startup instruction to the second host 130, the method further includes:

[0075] Step S340, obtaining the migration status of the virtual machine data of the target virtual machine and the virtual machine status of the target virtual machine;

[0076] Step S350, when the migration status is completed and the virtual machine status is turned on within a preset time after the migration is completed, clear the virtual machine data of the target virtual machine in the local memory of the first host machine 120; or,

[0077] Step S360 , when the migration status is completed and the virtual machine status is in a shutdown state within a preset time after the migration is completed, the virtual machine data of the target virtual machine is rolled back to the first host machine 120 .

[0078] Specifically, after the first host machine 120 transfers the virtual machine data of the target virtual machine to the second host machine 130, the first host machine 120 monitors the migration status of the virtual machine data of the target virtual machine and the virtual machine status of the target virtual machine. The migration status is migrating or migration completed, and the virtual machine status is powered on or powered off. When the migration status is migration completed, it means that the target virtual machine has been completely migrated to the second host machine 130. Then, based on the virtual machine status within the preset time after the migration is completed, it is judged whether the second host machine 130 supports the successful startup of the target virtual machine. If the virtual machine status is powered on within the preset time after the migration is completed, it means that the target virtual machine is successfully started on the second host machine 130. Then, the virtual machine data of the target virtual machine in the first host machine 120 can be cleared, thereby releasing part of the processor resources and part of the storage space of the first host machine 120, so that the first host machine 120 can continue to carry other virtual machine loads.

[0079] If the virtual machine state is in the shutdown state within a preset time after the migration is completed, it means that the target virtual machine fails to start on the second host machine 130. The first host machine 120 rolls back the virtual machine data of the target virtual machine, thereby achieving the normal instance being restored even if the target virtual machine fails to start.

[0080] In one embodiment, Fig. 9 As shown, a virtual machine startup method is provided, which is applied to the second host machine 130, and the method includes:

[0081] Step S410, receiving a startup instruction from the first host machine 120 and virtual machine data of a target virtual machine, and monitoring the migration status of the virtual machine data, wherein the startup instruction is used to start the target virtual machine, and the target virtual machine is any virtual machine that is free of charge when shut down.

[0082] Specifically, when the second host machine 130 receives the startup instruction and the virtual machine data of the target virtual machine sent by the first host machine 120, it indicates that the first host machine 120 that originally carried the target virtual machine cannot support the startup of the target virtual machine, and the available resources of the second host machine 130 meet the resource requirements of the target virtual machine. In this case, the target virtual machine needs to be migrated from the first host machine 120 to the second host machine 130 before being started. The virtual machine data of the target virtual machine includes configuration data and storage files. When the storage files of the target virtual machine are stored in the first host machine 120, the first host machine 120 will copy the storage files of the target virtual machine to the intermediate database, and the second host machine 130 will then copy and obtain the storage files of the target virtual machine from the intermediate database; when the storage files of the target virtual machine are stored in the cloud disk, the second host machine 130 will access the cloud disk 1 through the cloud disk storage interface corresponding to the target virtual machine to obtain the storage files corresponding to the target virtual machine.

[0083] Step S420: When the migration status is migration completed, start the target virtual machine according to the start instruction, and update the virtual machine status of the target virtual machine.

[0084] Specifically, when the second host machine 130 detects that the migration status is completed, it starts the target virtual machine according to the startup instruction, and updates the virtual machine status of the target virtual machine according to the startup result. If the startup is successful, the virtual machine status of the target virtual machine is updated to the power-on state, and if the startup fails, the virtual machine status of the target virtual machine is kept in the power-off state. Even if the first host machine 120 cannot start the target virtual machine as the target host machine, in the process of migrating the target virtual machine from the first host machine 120 to the second host machine 130, there is no need for frequent interaction between the first host machine 120 and the second host machine 130, so the migration time of the target virtual machine can be shortened, thereby solving the problem that the startup process of the existing virtual machine that is free of charge is time-consuming.

[0085] Figure 3-9 FIG. 1 is a flow chart of a method for starting a virtual machine in one embodiment. It should be understood that although Figure 3-9 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 3-9 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.
