Abstract

The embodiment of the invention discloses a load balancing control method and related devices so as to optimize the load balancing effect. The method includes the steps of determining a virtual machine to be transferred according to the loads of all physical NUMA nodes and the loads of all the virtual machines, representing the virtual machine to be transferred as the target virtual machine, calculating transfer expenses spent on transferring the target virtual machine according to different transferring methods, and transferring the target virtual machine according to the transferring method with the lowest expenses. Visibly, when the virtual machine to be transferred is determined, the loads of the physical NUMA nodes and the loads of the virtual machines are taken into consideration; due to the fact that the loads of the physical NUMA nodes are taken into consideration, the load balancing effect of all the physical NUMA nodes is superior to the load balancing effect in the prior art after transferring is conducted. In addition, the transferring method with the lowest expenses is selected according to the transferring expenses of the virtual machines, and transferring cost can be reduced while load balancing is achieved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a load balancing control method and a related device. Background technique [0002] With the development of virtualization and cloud computing, virtual machines are widely deployed on physical machines (physical servers) of non-uniform memory architecture (Non-uniform Memory Architecture, NUMA). [0003] A physical machine based on the NUMA architecture includes multiple physical processors and multiple memories. The aforementioned multiple physical processors and multiple memories can be divided into multiple groups (also called physical NUMA nodes). [0004] In implementing the present invention, the inventors found that in the prior art, the memory distribution of each physical NUMA node is adjusted according to the load of the virtual machine running on the physical machine, so as to achieve load balancing of each physical NUMA node. However, this load balanc...
