Abstract

The invention provides a dynamic fault tolerance method, system and device for virtual machine migration and a storage medium. The method comprises the steps of generating an ant colony for a migration task of each virtual machine; marking the migration network for the virtual machine through pheromones; starting initialized pheromones to determine the state of migrating network resources; settinga plurality of migration check points for each migration task; in the migration process of each virtual machine, if the migration task is successfully executed, updating the pheromone corresponding to the current migration network through the ant colony; and if execution of the migration task fails, submitting the last migration check point of the migration task to another migration network, updating local pheromones, and publishing migration network resources of each virtual machine together with the updated pheromones for allocation of the next migration task. The invention is used for improving the virtual machine migration efficiency.

Description

technical field [0001] The invention relates to the field of virtual machine migration in a virtualization environment, in particular to a dynamic fault-tolerant method, system, device and storage medium for virtual machine migration. Background technique [0002] With the rapid development of science and technology, the application of virtualization management systems is becoming more and more extensive. In virtualization and hyper-convergence projects, the purpose of virtual machine migration is to achieve system maintenance and management, high system load balancing, and enhanced system errors. tolerance and optimize system power management. There are usually two commonly used data transmission methods: a hypervisor-based transmission mechanism, that is, data transmission through a connection between hosts; a libvirtd-based transmission mechanism, that is, data transmission between two libvirtd processes. When the migration channel or the physical host where the virtual ...
