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.
