KubeVirt is an open-source project that brings virtual machines into the Kubernetes control plane, letting teams run VMs and containers side by side under the same orchestration, tooling, and lifecycle model. It packages VMs as Kubernetes objects so operators can manage both workload types with a single platform and the same CI/CD, observability, and policy tooling. Adoption of KubeVirt has accelerated recently for pragmatic reasons. Organizations that historically relied on VMware are re-evaluating their virtualization stack, and many are looking to reduce vendor lock-in and consolidate infrastructure around Kubernetes. That shift is driving interest in container-native virtualization to modernize VM workloads without ripping and replacing them. What live migration means Live migration is the ability to move a running VM from one host to another with minimal or no downtime. In traditional hypervisor environments (for example VMware vMotion), live migration preserves the guest memory, device state, and network connectivity so applications keep running while the VM moves. KubeVirt implements the same concept inside Kubernetes: it transfers memory and device state between nodes while the VM continues to run, enabling maintenance, load rebalancing, and non-disruptive failover. “Without shared storage, the target node cannot attach the VM disk while the source is still running, and live migration is not possible.” A critical requirement for KubeVirt live migration is that the VM’s disk must be accessible from both source and target nodes simultaneously — in Kubernetes terms, …
