Other scenarios may include hardware failures, node replacement, software issues and so on. Without the live migration option, each reboot would be very difficult for an administrator as all the running VMs would have to be stopped first before reboot occurs. This will cause major downtime in a mission-critical virtual environment.

With the live migration option, a running VM can be moved to another node without downtime. During a live migration, the VM does not experience any major slowdown. After the node reboots, simply migrate VMs back to the original node. Any offline VMs can also be moved with ease.
