Performance Study of Live Virtual Machine Migration using KVM Hypervisor
Journal Title: Indian Journal of Computer Science and Engineering - Year 2015, Vol 6, Issue 6
Abstract
In a cloud computing environment, migrating operating system instances across distinct physical hosts is a useful tool for administrators of data centers and clusters: It allows a clean separation between hardware and software, and facilitates fault management, load balancing, and low-level system maintenance. Live migration allows moving a continuously running VM from one physical host to another. It provides special benefit for data centers in a variety of scenarios including load balancing, maintenance and power management. Live migration is of two types: (1) Pre-copy live migration and (2) Post-Copy live migration each having its own advantages and disadvantages. In this report performance evaluation of post-copy live migration is presented along with proper mathematical modeling. This model can be used to estimate the Downtime, Resume Time and Total Migration Time of a VM being transferred using post-copy live migration
