It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

FIG. 1 is a flowchart of a method for managing batch migration of virtual machines provided by the present invention. The methods shown in Figure 1 include:

Step 101, receiving a virtual machine batch migration task package, wherein the task package includes migration tasks of at least two virtual machines;

Step 102, acquiring resource configuration information of the virtual machine in the task package and business information processed by the virtual machine;

Step 103: Calculate the processing priority of the migration of the virtual machine according to the resource configuration information of the virtual machine and the business information processed by the virtual machine;

Step 104, sorting the processing priorities;

Step 105 , process the virtual machine migration tasks in sequence according to the sorted processing priorities.

In the method embodiment provided by the present invention, by reading the configuration of the virtual machine and its business importance information, the virtual machine scheduling tasks in the virtual machine migration task package are reordered, issued and executed, and the resources and business of the cloud data center are guaranteed. Under the premise of stability, realize efficient and batch migration of virtual machines and improve the competitiveness of cloud computing operating systems.

The method embodiment provided by the present invention is described further below:

When a virtual machine performs a task, it needs certain hardware conditions to support the virtual machine to complete the task processing. When the virtual machine is migrated, the hardware resources of the virtual machine must be considered. Therefore, it is necessary to maintain the resource configuration information of each virtual machine , including but not limited to hardware resource information, such as at least one of CPU, memory and storage resource configuration information.

At the same time, when the virtual machine is migrated, some services will continue to be processed. Therefore, in order to ensure timely processing of important services, it is necessary to ensure that the virtual machine that is processing important services completes the migration as soon as possible. Therefore, using the identifier of the virtual machine as an identification mark, the tasks processed by each virtual machine and the importance of the processing tasks are recorded, so as to know the service information processed by the virtual machine in real time.

Different businesses have different importance in the cloud system, such as real-time computing, big data services, WEB information query, etc., and their importance decreases in turn. Of course, the business can also be divided according to actual needs, and the corresponding importance can be set for the task.

For example, in practical applications, the data center administrator maintains a relationship table of the importance of virtual machines in the data center and the business running on them, which contains three elements: virtual machine name-running business information-importance, specifically :

[{'vm1','real-time computing',5},

{'vm2','big data service',4}

...].

It can be seen from the above that the service information processed by the virtual machine includes the type of task processed by the virtual machine and the importance of the task.

Therefore, according to the resource configuration information of the virtual machine and the service information processed by the virtual machine, calculating the processing priority of the virtual machine migration includes:

Perform weighted calculation on at least two of CPU, memory, storage and service to obtain the processing priority of the virtual machine migration.

For example, the weighted calculation formula according to task priority may be D=cpu*20%+memory*20%+storage*20%+business*40%.

Among them, the higher the task execution priority calculated by the weighting formula is, the higher the task priority is, the higher the priority must be to migrate this type of virtual machine under the condition that the data center resources are limited and the priority is to ensure the stability of the important business.

The above-mentioned weights can be dynamically adjusted according to the actual situation. When the performance bottleneck is the CPU, the weight of the CPU can be increased, and on the contrary, the weight of the CPU can be lowered.

According to the sorted processing priority, virtual machine migration tasks are processed sequentially, including:

Selecting a physical host that provides the resource configuration information for the virtual machine according to the resource configuration information of the virtual machine;

Migrating the virtual machine to the physical host.

FIG. 2 is a flowchart of a method for batch migration of virtual machines based on configuration and business importance provided by the present invention. The implementation process of the method shown in Figure 2 is as follows:

Task receiving module: receive virtual machine batch migration task packages from the operation page of the cloud computing operating system;

Task analysis module: sequentially read the virtual machine information in the migration task package, including the virtual machine configuration information (such as CPU, memory, storage) and the business (job) information associated with the virtual machine, and then calculate the weighted formula according to the task priority D=cpu*20%+memory*20%+storage*20%+job*40% Calculate task priority, and reconstruct the migration task package according to the order of task priority from large to small

Among them, the load of the virtual machine business information maintenance module maintains the virtual machine related business importance information table. Specifically, different businesses have different (relative) importances, such as real-time computing, big data services, and WEB information queries. Decrease in turn. The data center administrator maintains the relationship table between the virtual machines in the data center and the importance of the business running on them, which contains three elements: virtual machine name-running business information-importance, specifically:

[{'vm1','real-time computing',5},

{'vm2','big data service',4}

...];

Among them, the higher the priority of the task, the highest priority is executed. Corresponding to the real-world processing idea: when the configuration of the virtual machine is higher and the importance of the associated business is higher, the task execution priority calculated by the weighting formula is higher, and the priority is to ensure the stability of the important business when the data center resources are limited. Under certain conditions, it is necessary to preferentially migrate this type of virtual machines with high task priority.

Task distribution module: obtain the reordered task execution packages, and sequentially distribute virtual machine migration tasks to the scheduling module according to the task priority;

Scheduling module: according to the configuration in each specific virtual machine migration task, schedule the selected destination physical host in the data center resource pool;

For example, the resource configuration of the destination physical host meets the resource requirements required for migration. For example, if the configuration of the virtual machine is CPU 10G memory 10G disk 50G, the CPU/memory/disk available on the destination physical host must meet its configuration requirements.

Execution module: For each virtual machine migration task, perform specific migration operations according to the selected destination host information;

Statistical module: record the execution results of virtual machine batch migration operations, and perform summary analysis, such as information display such as execution success or failure, time spent, task exceptions, etc.;

Log module: It mainly records operation logs such as user operations, migration execution, and exception capture during the entire migration operation, and is used to analyze, locate, and solve problems that occur during the migration process.
