Live migration moves a running virtual machine from one physical host to another with little or no perceptible downtime by copying its memory and state across the network while it keeps executing. It lets operators evacuate hosts for maintenance, rebalance load, and improve resilience without interrupting tenants. It depends on shared or replicated storage and fast networking, and is a cornerstone of flexible data-center virtualization.
