What is virtualization? - Virtualization is a broad computing term used for running software, usually multiple operating systems, concurrently and in isolation from other programs on a single system. Most existing implementations of virtualization use a hypervisor, a software layer or subsystem that controls hardware and provides guest operating systems with access to underlying hardware. The hypervisor allows multiple operating systems, called guests, to run on the same physical system by offering virtualized hardware to the guest operating system.

With storage migration, a running virtual machine (as well as its in-use storage) can be migrated from one host to another with no downtime. This capability can be used to optimize performance of virtual machines. +
