Application performance analysis during live migration of virtual machines

Abstract

Live migration is an essential feature in virtualization technology where a running Virtual Machine (VM) from one physical host is migrated to another physical host without any service disruptions. Indisputably the benefits reaped from VM migration are high availability, load balancing, energy saving and disaster recovery which are the desired data centre attributes. The migration is initiated by the administrator and part of the migration procedure is to make an informed decision to isolate and identify an appropriate VM to be migrated, lest an impressive performance may not be achieved. The decision of selecting the right candidate VM to be migrated depends on parameters like total migration time, down time, total transferred data and page dirty rate. The nature of the application influences these parameters. The paper addresses the analysis of some of these parameters empirically, and based on these data a correct VM to be migrated is chosen. In addition to the above, this paper also discusses the dynamic resource allocation for RSA algorithm and JMeter.

Resumption of virtual machines after adaptive deduplication of virtual machine images in live migration

“…3) The working set of pages of VM memory from the origin moved to the destination. 4) A few memory pages of a virtual machine are modified (dirtied) during the migration process and are transferred again and again iteratively in several rounds until the copying rate greater than the dirtying rate [11] (Iterative Pre-copy). [12].…”

Performance Analysis of Live and Offline VM Migration Using KVM

“…In a research by [11], the authors mentioned various benefits that could be achieved by the VM migration, such as high availability, fault tolerance, energy saving etc. They analyzed some parameters used during migration, such as total migration time, downtime; amount of data transferred empirically and proposed to choose right VM for migration.…”
