Resource scheduling method of cluster virtual machine

Abstract

The invention discloses a resource scheduling method of a cluster virtual machine. The resource scheduling method comprises the following steps of: acquiring resource utilization parameters of each physical host in the cluster for a first preset time period before the current time point; according to the resource utilization parameter and the preset physical host selection strategy, determining a target physical host having need to migrate the virtual machine; determining a target virtual machine to be migrated in the target physical host; determining a target host machine according to the resource utilization parameter; and migrating the target virtual machine to the target physical host. The target virtual machine in the target physical host is migrated to the target host machine. Through the dynamic migration of the virtual machine, the virtual machine on the target physical host with high resource utilization can be migrated to other physical hosts to realize dynamic load balance of the physical hosts, and fully use a variety of physical resources in the cluster, so that the problem of resource imbalance in the cluster is solved and efficient resource utilization is maintained.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a resource scheduling method for a cluster virtual machine. Background technique [0002] With the rapid development of computer technology and the Internet. The virtualization technology of the operating system is becoming more and more mature. The virtualization system allows multiple operating systems to run concurrently on the same physical host, using the same hardware, without affecting each other. [0003] Multiple virtual machines can form a cluster, and the cluster system has gradually become the focus of the computer industry due to its low cost, powerful computing power and fault-tolerant mechanism. However, due to the differences in the applications running in the virtual machine and the performance of the host physical host, this may cause resource load imbalance during the operation of the cluster and affect the normal operation of the application. [0004] Ther...
