In short VMware vMotion enables the live migration of VMs from one host to another with continuous uptime. It allows admins to perform server maintenance without disrupting guest VMs, and it makes disaster recovery faster and more efficient. In addition, vMotion facilitates VM load balancing across physical hosts. That improves VM performance and optimizes resource usage.VMware vMotion works with other VMware features -- VMware Distributed Resource Scheduler, Distributed Power Management and Update Manager -- to provide load balancing and make it easier to perform server maintenance.
