Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in further detail with reference to specific embodiments. It should be noted that the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other without conflict.
The inventor of the application provides that the resource use condition of each host under the cluster can be monitored in real time, and the load state of the cluster can be judged quickly and accurately by utilizing an algorithm for automatically judging the integral load state of the cluster according to the resource monitoring result of the cluster. The judgment result is used as the basis of resource scheduling control, for example, the resource use condition result can be used as the input of a scheduling algorithm, the virtual machine is dynamically migrated to a certain host, the aims of energy conservation and load balancing are finally achieved, and a large amount of time for repeated calculation can be saved.
Based on the above thought, the present embodiment provides a cluster filling method based on vmware virtualization, as shown in fig. 1, including the following operations:
in this context, the trigger condition for determining the priority of each host participating in the cluster filling policy under the cluster may be real-time or periodic.
For example, the resource usage of the cluster is monitored in real time through a wave cloud-cloud data center management platform, the resource usage of each host under the cluster is monitored in real time, the load state of each host under the cluster is automatically determined according to the monitoring data, when the load state of any one or more hosts changes, the virtual machines under the cluster are automatically adjusted according to the requirements, that is, the priority of each host participating in the cluster full-filling strategy under the cluster is determined according to the load state of each host.
Or, when the resource usage of each host under the cluster is monitored according to a preset period, the priority of each host participating in the cluster filling policy under the cluster can be determined.
In addition, when migration is performed according to the load state of the host under the cluster, the host which does not exceed the highest load host and has the smallest migration number of the virtual machines is preferentially selected, and dynamic adjustment of the virtual machines under the virtual machine cluster is performed. That is, the priority of the host may be inversely proportional to the total number of times of virtual machine migration on the host, in addition to being inversely proportional to the load state of the host, that is, the higher the load of the host, the lower the priority, the lower the load of the host, and the higher the priority. The higher the total number of virtual machine migration on the host is, the lower the priority is, and the smaller the total number of virtual machine migration on the host is, the higher the priority is.
The load state of the host referred to herein includes resource usage conditions such as CPU and memory load, which are not limited in particular.
Step 200: and migrating the virtual machine on the host with the lowest priority to the host with the highest priority according to a preset cluster filling strategy until the load of the host with the highest priority reaches the upper line, migrating the rest virtual machines on the host with the lowest priority to the host with the second highest priority until the load of the host with the second highest priority reaches the upper line, and so on until all the virtual machines finish migrating.
The following describes the implementation of the above step 200 in detail.
The principle of the cluster filling strategy is shown in fig. 2.
The process of presetting the cluster filling strategy is as follows:
firstly: a VMware virtualization environment must be provided, and the VMware environment must have two or more server host devices to which the same VMware server virtualization system is installed.
Then: and configuring a cluster filling strategy for the VMware virtualization platform.
A cluster is selected for which an application fill-up policy is to be applied.
Virtual machines are selected that need to be migratable with the fill policy applicable.
The number of virtual machines that are migrated from one host to another at a single time (i.e., the maximum number of virtual machines migrated at a single time) is selected.
Configuring a cluster filling strategy:
and migrating the virtual machines on the host with the lowest priority to the host with the highest priority according to the maximum migration number of the single virtual machines until the load of the host with the highest priority reaches the online state, and migrating the virtual machines to the host with the second highest priority.
It should be further noted that, in addition to the above cluster full policy, the virtual machine on the host with the lowest priority may be migrated, and the virtual machine on the host with the lowest priority may also be migrated to achieve the purpose of load balancing, where the cluster full policy further includes:
after the migration of the virtual machine on the host with the lowest priority is completed, the virtual machine on the host with the second lowest priority is migrated to the host with the highest priority in the hosts which do not reach the load online state until all the hosts participating in the cluster filling strategy reach the load balance. For example, after the migration of the virtual machine on the host with the lowest priority is completed, the host with the highest priority still does not reach the online state, and then the virtual machine on the host with the second lowest priority is migrated to the host with the highest priority until the host with the highest priority reaches the online state.
The process of executing the cluster filling strategy of the VMware virtualization platform is as follows:
and S1, acquiring all virtual machines applying the cluster filling strategy of the VMware virtualization platform.
And S2, acquiring all hosts applying the cluster filling strategy of the VMware virtualization platform.
And S3, arranging the optimal host filling sequence according to the load state of each host and the load conditions of all the virtual machines in sequence. Wherein the smaller the host load, the more priority the host fill.
And S4, according to the optimal host filling sequence and the maximum migration number of the single virtual machines, filling the virtual machines on the host with the lowest priority to the host with the highest priority until the host load is on line, and then continuing the migration of the host with the second priority until the migration is completed.

Since the above-described vmware virtualization-based cluster filling method can be implemented by the above-described apparatus, the specific implementation of the apparatus, such as the cluster filling policy and the operations of virtual machine migration, can refer to the above-described related contents, and will not be described herein again.
