Background technique

With the rapid development of cloud computing, virtualization technology has also developed rapidly. As a resource management technology, virtualization technology is to put various physical resources of computers, such as servers, networks, memory and storage. Abstraction, rendering after transformation, breaking the uncuttable barrier between the physical structures, so that users can apply these resources in a better way than the original configuration, and these virtualized resources are not subject to the existing resources. Or physical configuration restrictions. In a virtualized environment, all virtual machines on the same physical machine share memory resources, but each virtual machine has different load at runtime. Therefore, the virtual machine needs different physical memory. In addition, the same virtual machine is in the same virtual machine. The demand for physical memory at different times of the load at runtime is also dynamically changing. Therefore, in order to improve the utilization of physical memory and accurately analyze the actual demand of the virtual machine for physical memory, it is important to adjust the physical memory of the virtual machine according to the actual amount of physical memory allocated by the virtual machine.

The scheduling method of the virtual machine memory resource provided by the prior art generally monitors the memory usage of the virtual machine in real time through software, and adjusts the physical memory according to the real-time physical memory requirement of the virtual machine, if the virtual machine is actually The required physical memory is smaller than the physical memory allocated to it. The virtual machine needs to free some of the unused physical memory. If the virtual machine actually needs more physical memory than the physical memory allocated to it, you need to allocate physical memory to the virtual machine. For example, VMM (Virtual Machine Monitor) allocates physical memory to the virtual machine.

The scheduling method of the virtual machine memory resource provided by the above prior art has obvious drawbacks.

The scheduling method of the virtual machine memory resource provided by the prior art has low utilization rate of physical memory, and the memory resource on the physical machine may have idle resources that are not allocated to the virtual machine, resulting in low utilization of the memory resource; The physical resources given to the virtual machine may be idle for a period of time and are not being run by the virtual machine.

detailed description

Numerous specific details are set forth in the description below in order to provide a thorough understanding of the application. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar promotion without departing from the scope of the present application, and thus the present application is not limited by the specific embodiments disclosed below.

The present application provides a scheduling method for a virtual machine memory resource, and the present application further provides a scheduling device for a virtual machine memory resource, and an electronic device. The following is a detailed description of the embodiments of the embodiments provided herein, and the various steps of the method are explained.

The method for scheduling a virtual machine memory resource provided by the present application is as follows:

1 is a flowchart of processing a method for scheduling a virtual machine memory resource provided by the present application, and further, a relationship between steps of the virtual machine memory resource scheduling method embodiment, Please according to Figure 1 is determined.

Step S101: Calculate a target memory scheduling interval of the resource scheduling instruction according to a configuration parameter included in a resource scheduling instruction of the physical machine.

The resource scheduling instruction in the embodiment of the present application is a scheduling instruction sent by a physical machine for scheduling physical memory of a virtual machine on a physical machine. For example, a dispatch instruction sent by an external business party when applying for a memory resource. The resource scheduling instruction includes configuration parameters of the specifically invoked virtual machine. The configuration parameters include: the number of virtual machines, the identifier, the lower limit of the memory, the upper limit of the memory, the minimum free memory, and the maximum free memory.

The number of the virtual machines refers to the number of virtual machines that need to be scheduled, and the identifiers are used to distinguish each virtual machine that needs to be scheduled.

The lower limit of the memory refers to the minimum memory allocated to the virtual machine. In practice, the lower limit of the memory may be the minimum physical memory required for the virtual machine to run on the physical machine. This part of the physical memory must be satisfied. Otherwise, the virtual machine may not be able to start.

The upper memory limit value refers to the maximum memory allocated to the virtual machine. In practice, the upper memory limit value may be the maximum physical memory required for the virtual machine to run on the physical machine and reach the maximum load. When the memory resources on the physical machine are relatively tight, the physical memory can be scheduled by compressing the upper memory limit.

The minimum free memory refers to the physical memory required to ensure the worst performance of the virtual machine (excluding the physical memory required for the virtual machine itself to run), when scheduling the memory resources on the physical machine, this part Physical memory is not compressed, because once the virtual machine's minimum free memory is compressed, the virtual machine is likely to fail due to failure to meet the minimum load.

The maximum free memory refers to the physical memory allocated to the virtual machine when the memory resources are sufficient (excluding the physical memory required for the virtual machine itself to run), and when the memory resources on the physical machine are relatively tight, Scheduling physical memory by compressing the maximum free memory.

For example, the configuration parameters included in the resource scheduling instruction A are as follows:

The number of virtual machines is N: 5;

Lower memory limit lower: 10G;

The upper limit of memory is upper: 20G;

Minimum free memory lower_free: 1G;

Maximum free memory upper_free: 2G.

Alternatively, the configuration parameters included in the resource scheduling instruction B are as follows:

The number of virtual machines is N: 4;

Identification: vm1, vm2, vm3 and vm4;

Vm1 memory lower limit lower: 1G, memory upper limit upper: 2G, minimum free memory lower_free: 100M, maximum free memory upper_free: 200M;

Vm2 memory lower limit lower: 1G, memory upper limit upper: 2G, minimum free memory lower_free: 100M, maximum free memory upper_free: 200M;

Vm3 memory lower limit lower: 10G, memory upper limit upper: 20G, minimum free memory lower_free: 1G, maximum free memory upper_free: 2G;

Vm4 memory lower limit lower: 10G, memory upper limit upper: 20G, minimum free memory lower_free: 1G, maximum free memory upper_free: 2G.

It should be noted that the physical memory of each virtual machine on the physical machine is scheduled to be: the physical memory of each virtual machine on the physical machine can support its startup, and the memory resources on the physical machine are in a state of tension, that is: The physical memory allocated to the virtual machine is greater than the lower memory limit and smaller than the upper memory limit. In this case, the physical memory of each virtual machine on the physical machine needs to be scheduled. Based on this, the target memory scheduling interval refers to a scheduling condition that can be satisfied for scheduling physical memory of each virtual machine on the physical machine, where the target memory scheduling interval is set with an upper limit value and a lower limit value, where The lower limit value of the target memory scheduling interval is equal to the sum of the memory lower limit values of the virtual machines included in the resource scheduling instruction; the upper limit value of the target memory scheduling interval is equal to the resource scheduling instruction The sum of the memory upper limits of each virtual machine.

For example, the configuration parameters included in the resource scheduling instruction A are: the number of virtual machines N: 5; the lower limit of memory lower: 10G; the upper limit of memory upper: 20G; the minimum free memory lower_free: 1G; the maximum free memory upper_free: 2G ;

Then the lower limit of the target memory scheduling interval is lower*5=10G*5=50G;

The upper limit of the target memory scheduling interval is: upper*5=20G*5=100G.

In a specific implementation, the virtual machines deployed on the physical machine may be deployed in a preset sequence. If the virtual machine is deployed on the physical machine according to a preset sequence, the virtual machine in the first place has scheduling other Permissions for virtual machine memory. For example, 10 virtual machines deployed on a physical machine: vm1 to vm10, wherein vm1 has the authority to manage vm2 to vm10.

Step S102, determining whether the available memory on the physical machine is within the corresponding range of the target memory scheduling interval.

In a specific implementation, before the execution of this step, an available memory computing operation is performed to calculate available memory on the physical machine, the available memory is equal to the physical memory of the physical machine minus the virtual machine and the operation on the physical machine. The system occupies memory, ie:

Available memory memory_used=physical machine actual memory host_total-virtual machine memory

- The operating system occupies memory host_used;

Where n is the number of virtual machines on the physical machine.

Based on the above, the available memory of the physical machine calculated according to the above, and the target memory scheduling interval obtained according to the above step S101, in this step, determining whether the available memory on the physical machine is in the target memory scheduling interval. Within the scope, the specific implementation is as follows:

Determining whether the available memory is less than an upper limit value of the target memory scheduling interval;

If it is smaller, determining whether the available memory is greater than or equal to a lower limit value of the target memory scheduling interval;

If yes, performing the following step S103, allocating a virtual machine to the resource scheduling instruction on the physical machine according to the configuration parameter, and allocating the available memory to the virtual machine;

If not, it indicates that, for the current resource scheduling instruction, the memory resource on the physical machine cannot meet the requirement of the resource scheduling instruction for the memory resource, and sends a reminder message that the memory is insufficient.

For example, the lower limit of the memory of the above five virtual machines is 10G, the lower limit of the target memory scheduling interval is 50G; the available memory memory_used is 48G, which is less than the lower limit of the target memory scheduling interval, and 4 virtual before the startup. When the machine is running, the memory allocated by each virtual machine is 10G. When the fifth virtual machine is started, because the remaining memory 8G on the physical machine is less than the lower limit of the memory lower10G, the fifth virtual machine cannot be started, indicating that the physical There is no way for the memory resources on the machine to satisfy the current resource scheduling instruction. The virtual machine is no longer started for the current resource scheduling instruction and the memory allocation is performed, and a reminder message for insufficient memory is issued.

If it is greater than or equal to the upper limit value of the target memory scheduling interval, it indicates that, for the current resource scheduling instruction, the memory resources on the physical machine are sufficient, and there is no resource between the virtual machines on the physical machine. Competing for the maximum demand for memory resources of each virtual machine included in the resource scheduling instruction, where, for each virtual machine in the configuration parameter, the memory upper limit value is used in the configuration parameter. Each virtual machine allocates memory, that is, allocates the maximum physical memory corresponding to the upper limit of the memory to each virtual machine in the configuration parameter.

For example, the upper limit of the upper limit of the above five virtual machines is 20G, and the upper limit of the target memory scheduling interval is 100G; the available memory memory_used is 120G, which is greater than the upper limit of the target memory scheduling interval of 100G, for each virtual Machines, respectively, allocate 20G of physical memory.

In addition, in a specific implementation, it is determined whether the available memory on the physical machine is in the range corresponding to the target memory scheduling interval, and other parties may be used in addition to the foregoing implementation manner provided in this embodiment. For example, determining whether the available memory is greater than or equal to a lower limit value of the target memory scheduling interval; if greater than or equal to a lower limit value of the target memory scheduling interval, determining whether the available memory is smaller than the target An upper limit value of the memory scheduling interval; if less, performing the following step S103, allocating a virtual machine to the resource scheduling instruction on the physical machine according to the configuration parameter, and allocating the available memory to the virtual machine; If it is greater than or equal to the upper limit value of the target memory scheduling interval, the memory upper limit value is allocated to each virtual machine in the configuration parameter; if less than the lower limit value of the target memory scheduling interval, it indicates For the current resource scheduling instruction, the memory resource on the physical machine cannot meet the requirement of the resource scheduling instruction for the memory resource, and sends a reminder message that the memory is insufficient.

Step S103: Allocate a virtual machine for the resource scheduling instruction on the physical machine according to the configuration parameter, and allocate the available memory to the virtual machine.

The premise that the step is implemented is that the step S02 determines whether the available memory on the physical machine is within the corresponding range of the target memory scheduling interval, that is, the available memory on the physical machine is smaller than the target memory scheduling interval. The upper limit value is greater than or equal to the lower limit value of the target memory scheduling interval. In this step, a virtual machine is allocated to the resource scheduling instruction on the physical machine according to the configuration parameter, and the available memory is allocated to the virtual machine, and the specific implementation is as follows:

Performing the following memory allocation operation for each virtual machine in the configuration parameter, and calculating the available memory of the physical machine once for each virtual machine, and substituting the calculated available memory into the following memory allocation operating:

1) calculating, according to the configuration parameter and the actual occupied memory of each virtual machine in the configuration parameter, a first memory allocation threshold, a second memory allocation threshold, and a third memory allocation threshold of each virtual machine in the configuration parameter. And a fourth memory allocation threshold;

The first memory allocation threshold is equal to a sum of an actual occupied memory of the virtual machine and the maximum free memory; and the second memory allocation threshold is equal to a sum of an actual occupied memory of the virtual machine and the minimum free memory; The third memory allocation threshold is equal to a sum of the memory lower limit value and the maximum free memory; and the fourth memory allocation threshold is equal to a sum of the memory lower limit value and the minimum free memory.

For example, for virtual machine vm1:

The first memory allocation threshold memory_value1=the actual occupied memory memory_current+the largest free memory upper_free=14G+2G=16G;

The second memory allocation threshold memory_value2=the actual occupied memory memory_current+the minimum free memory lower_free=14G+1G=15G;

The third memory allocation threshold memory_value3=memory lower limit lower+max free memory upper_free=10G+2G=12G;

The fourth memory allocation threshold memory_value4=memory lower limit lower+minimum free memory lower_free=10G+1G=11G.

2) summing, respectively, a first memory allocation threshold, a second memory allocation threshold, a third memory allocation threshold, and a fourth memory allocation threshold of the remaining virtual machines;

3) determining whether the available memory is greater than or equal to a sum of the first memory allocation thresholds;

If greater than or equal to the sum of the first memory allocation thresholds, allocate memory according to the first memory allocation threshold;

For example, if the resource scheduling instruction A includes the parameters of the five virtual machines, the first memory allocation threshold memory_value1 is 16G, and the sum of the first memory allocation thresholds is 16G*5=80G;

Assume that the available memory memory_used of the physical machine is 80G, which is equal to the sum of the first memory allocation thresholds of 80G, and allocates 16G physical memory to the first virtual machine vm1;

The memory allocation operation is repeated, and the memory allocated by the virtual machine vm2 to the virtual machine vm5 is 16G.

If the sum is less than the sum of the first memory allocation thresholds, perform the next step;

4) determining whether the available memory is greater than or equal to a sum of the second memory allocation thresholds;

If greater than or equal to the sum of the second memory allocation thresholds, allocate memory according to the second memory allocation threshold;

For example, if the resource scheduling instruction A includes the parameters of the five virtual machines, the second memory allocation threshold memory_value1 is 15G, and the sum of the first memory allocation thresholds is 15G*5=75G;

Assume that the available memory memory_used of the physical machine is 79G, which is greater than the sum of the second memory allocation threshold and 75G, and allocates 15G physical memory to the first virtual machine vm1;

The memory allocation operation is repeated, and the memory allocated by the virtual machine vm2 to the virtual machine vm5 is 16G.

If the sum is less than the sum of the second memory allocation thresholds, perform the next step;

5) determining whether the available memory is greater than or equal to a sum of the third memory allocation thresholds;

If greater than or equal to the sum of the third memory allocation thresholds, allocate memory according to the third memory allocation threshold;
