Pre-copy Based Live Migration Using Lossless Compression Algorithm

Abstract

Virtualization is a methodology of logically dividing computer resources. By emulating a complete hardware system, from processor to network card, each virtual machine can share a common set of hardware. It allows multiple virtual machines, with heterogeneous operating systems to run side by side on the same physical machine. Migration operation system instance across distinct physical hosts is a useful tool for administrators of data centers. . Live migration is done by performing most of the migration while the operating system is still running, achieving very little downtime. By carrying out the majority of migration while OSes continue to run, we achieve impressive performance with minimal service downtime and total migration time. In this paper, we propose the design, implementation, and evaluation of pre-copy based live migration using lossless compression algorithm for virtual machines (VMs) across a Gigabit LAN.
