Virtualization and Live Migration: Issues and Solutions

Abstract

With the increasing use of cloud computing and virtualization technology and the need to manage virtual machines, the virtual machine live migration technique is used for purposes such as load balancing, server repair, crash prevention, energy management, etc. Live Virtual Machine Migration The process of transferring a running virtual machine from a physical host to another with minimal disruption to ongoing services. This is a powerful tool that facilitates hardware Maintenance, load balancing, fault tolerance and energy saving in clusters and data centers. A key. The challenge of live migration is that it is difficult to achieve goals while minimizing them in migration Virtual machine living is subject to many parameters such as downtime, performance degradation, total migration time, data volume, and overhead, so migration issues have been raised as one of the most important issues in cloud computing. Cloud computing is also a new distributed computing technology based on virtualization technology. Virtualization is able to separate hardware and software management and provide portable environments for modern computing systems. One of the important achievements of virtualization is migration. The migration operation is performed for various purposes such as load balancing, online maintenance, and fault tolerance, energy management, reducing response time and repairing servers in data centers and computing clusters. In this article, we have examined virtualization and different methods of virtual machine migration.
