A method and device for verifying affinity rules based on load balancing

Abstract

The invention provides a method and a device for verifying affinity rules based on load balancing. The method comprises obtaining all DRS rules corresponding to a virtual machine to be migrated, wherein the types of the DRS rules include aggregating virtual machine rules, separating virtual machine rules and / or virtual machine-to-host rules; verifying all DRS rules corresponding to the virtual machine to be migrated in turn, and screening out a target host in the system, and the relationship between the target host and the virtual machine to be migrated satisfying all DRS rules corresponding to the virtual machine to be migrated. In the embodiment of the present application, affinity rule management is introduced in load balancing, and affinity rules can be set by users. The premise of load balancing scheduling is that the set affinity rules must be satisfied, so that the final scheduling is more intelligent and the scheduling result is more in line with the expectations and requirements of users.

Description

technical field The present application relates to the field of computer technology, in particular to a method and device for verifying affinity rules based on load balancing. Background technique In recent years, operating system virtualization technology has become increasingly mature. Xen, kvm, and vmware systems allow multiple operating system instances to run concurrently and independently on the same hardware resources. At the heart of these systems is a virtual machine monitor, or Hypervisor. The hypervisor provides a complete virtual hardware interface for guest operating systems, and schedules these guest operating systems to execute on physical hardware resources. A main feature of a virtual machine is that the guest operating system can be migrated online between different hosts. Due to the information uncertainty of the application program and the difference of the processing ability of the host, the load imbalance of the host in the virtual computing environm...

Problems solved by technology

However, in the prior art, most of the load balancing functions are automatically selected by the program to migrate the virtual machine and the target host according to the set threshold, which cannot meet the user's expectations well in many cases.
