Embodiment bis-
The present embodiment provides a kind of method of moving virtual machine based on embodiment mono-.
As shown in Figure 2, for according to the schematic flow sheet of the method for the migration virtual machine of the present embodiment.
Step 200, adopts underloading detection subalgorithm to obtain the first underloading value of each physical machine on physical equipment platform, and the physical machine that the first underloading value is more than or equal to underloading threshold value is as first object physical machine; Or adopt heavy duty detection subalgorithm to obtain the first heavy duty value of each physical machine on physical equipment platform, the physical machine that the first heavy duty value is more than or equal to heavily loaded threshold value is as first object physical machine.
This step 200 is for determining the operation of first object physical machine.In the present embodiment, each target physical machine and virtual machine physical machine can have respectively identification information separately.
Underloading in the present embodiment detects subalgorithm and is called again underloading index computational algorithm, and heavy duty detects subalgorithm and is called again heavily loaded index computational algorithm.
Adopt following formula to obtain the first underloading value L of each physical machine in physical equipment platform
i:
wherein i physical machine in i represents physical equipment platform, total k physical machine in physical equipment platform, i and k are the integer that is more than or equal to 1.
Wherein, in the time that the utilization rate of i physical machine is less than default underloading threshold value, the utilization rate of default i the physical machine of underloading threshold value-the of S=; In the time that the utilization rate of i physical machine is more than or equal to default underloading threshold value, L=0.
In the present embodiment, the utilization rate of i physical machine can represent memory usage, CPU usage of i physical machine etc., and underloading threshold value can be set according to actual needs, and the default underloading threshold settings in the present embodiment is 45%.Underloading threshold value also can be set according to actual needs, for example, be 0.In practical operation, can calculate respectively memory usage and the CPU usage of i physical machine, in the time that internal memory underloading value corresponding to memory usage and CPU underloading value corresponding to CPU usage are all greater than underloading threshold value, judging this physical machine is first object physical machine, need the virtual machine in this first object physical machine of migration, now, the first underloading value comprises internal memory underloading value and CPU underloading value.In the time that the first underloading value in first object physical machine is more than or equal to underloading threshold value, illustrate that the virtual machine in this first object physical machine is less, virtual machine (vm) migration in this first object physical machine can be moved away completely, and by electricity under this first object physical machine.
Adopt following formula to obtain the first heavy duty value H of physical equipment platform
i:
wherein i physical machine in i represents physical equipment platform, total k physical machine in the first frame, i and k are the integer that is more than or equal to 1.
Wherein, in the time that the utilization rate of i physical machine is greater than default heavy load door limit value, utilization rate-heavy load door limit value of Y=i physical machine; In the time that the utilization rate of i physical machine is less than or equal to default heavy load door limit value, H=0.
In the present embodiment, the utilization rate of i physical machine can represent memory usage, CPU usage of i physical machine etc., and default heavy load door limit value can be set according to actual needs, and the default heavy load door limit value in the present embodiment is set as 81%.Heavy duty threshold value also can be set according to actual needs, for example, be 0.In practical operation, can calculate respectively memory usage and the CPU usage of i physical machine, in the time that internal memory corresponding to memory usage heavy duty value and the heavily loaded value of CPU corresponding to CPU usage are all greater than heavily loaded threshold value, judging this physical machine is first object physical machine, need the virtual machine in this first object physical machine of migration, now, the first heavy duty value comprises internal memory heavy duty value and CPU heavy duty value.In the time that the heavy duty of first in first object physical machine value is more than or equal to heavily loaded threshold value, illustrate that the virtual machine in this first object physical machine is more, virtual machine (vm) migration in this first object physical machine can be gone out to a part, alleviate the burden of this first object physical machine.
In the time that scheduling of resource platform finds that according to above-mentioned algorithm the first underloading value of first object physical machine is more than or equal to underloading threshold value, judge this first object physical machine underloading, can be by the virtual machine (vm) migration in this first object physical machine on other physical machine, and this first object physical machine is carried out to lower electricity operation.In the time that scheduling of resource platform finds that according to above-mentioned algorithm the first heavy duty value of first object physical machine is more than or equal to heavily loaded threshold value, judge this first object physical machine heavy duty, can carry out the operation that powers on to some physical machine in the cluster virtual machine at this first object physical machine place, in the physical machine that virtual machine (vm) migration in this first object physical machine is powered on to these, to alleviate the burden of this first object physical machine.
Step 201, determines the virtual machine to be migrated in first object physical machine.

This step can be specifically:
Obtain the second load value of each physical machine of the physical machine cluster at physical machine to be migrated place;
The physical machine that the second load value is less than or equal to Second Threshold is as target physical machine.
In the present embodiment, the second load value can be the realtime power of each physical machine.This step is in order to determine the second target physical machine.Realtime power taking the second load value as each physical machine is example, because the each physical machine in the physical machine cluster at physical machine to be migrated place all can be used as virtual machine (vm) migration physical machine extremely, now, can therefrom select physical machine that a load value is lighter as the second target physical machine.Specifically can obtain as the above-mentioned method of obtaining the first underloading value the realtime power of each physical machine, and using the physical machine that wherein realtime power is less than Second Threshold as the second target physical machine.Can ensure that like this virtual machine (vm) migration is to this second target physical machine, this second target physical machine can not exceed rated power as far as possible.
Step 203, according to the parameter information of virtual machine to be migrated, inquiry the first parameter list, obtains the power prediction recruitment of the second target physical machine after virtual machine (vm) migration to be migrated.
This first parameter list is the first parameter list setting in advance, the increased power amount of the second target physical machine that this first parameter list comprises historical record after increasing the virtual machine of every type, or the mean value of the increased power amount of multiple virtual machine (vm) migrations of historical record after the second target physical machine.
This first parameter list can be pre-stored in resource management platform, also can be stored in independent storer, as long as can be got by resource management platform.
Step 204, obtains the current realtime power of the second target physical machine place frame.

Particularly, the realtime power of the frame at the second target physical machine place equals the realtime power sum of each physical machine in the frame at the second target physical machine place.The obtain manner of the realtime power of the frame at the second target physical machine place can also be: to the controller switching equipment in the frame at the second target physical machine place, for example intelligent PDU(Protocol Data Unit, protocol Data Unit PDU), the current realtime power of the frame at inquiry the second target physical machine place.Controller switching equipment can be by inquiring about the realtime power of each physical machine and calculating the realtime power sum of each physical machine, thereby obtain the realtime power of the frame at the second target physical machine place.
Step 205, according to the current realtime power of power prediction recruitment and the second target physical machine place frame, the predicted power of the frame of determining the second target physical machine place after virtual machine (vm) migration to be migrated.
Current realtime power+power prediction recruitment of the predicted power=the second target physical machine place frame of the frame at the second target physical machine place after virtual machine (vm) migration to be migrated.
Step 206, whether the load estimation situation that judges the frame at the second target physical machine place has exceeded first threshold, if predicted power is greater than the rated power of the frame at the second target physical machine place, perform step 207, if predicted power is less than or equal to the rated power of the frame at the second target physical machine place, perform step 208.
Step 207, if predicted power is greater than the rated power of the frame at the second target physical machine place, redefine for virtual machine to be migrated the 3rd target physical machine that need to move to, next return to execution step 203, using the 3rd target physical machine as the second new target physical machine.
Step 208, by virtual machine (vm) migration to be migrated to the second target physical machine.
It is pointed out that in the present embodiment, in the time there is no virtual machine in first object physical machine, by electricity under first object physical machine.In the time that the number of first object physical machine electric under needs is greater than 1, preferentially by electricity under the physical machine that in first object physical machine, refrigerating efficiency is minimum., in the time not having the number of physical machine of virtual machine to be greater than 1, by electricity under physical machine minimum refrigerating efficiency.
According to the method for the migration virtual machine of the present embodiment, in the time judging the virtual machine that need move in first object physical machine, first calculate the second target physical machine that underloading value determines that virtual machine need migrate to, then the realtime power of the frame at this target physical machine place after predicting on virtual machine (vm) migration to the second target physical machine, and judge whether this realtime power exceeds the rated power of this frame, determine whether on virtual machine (vm) migration to the second target physical machine according to judged result, to ensure after the operation of carrying out on virtual machine (vm) migration to the second target physical machine, the frame at the second target physical machine place can overflow fixed load, and then ensure the normal work of this frame.
