Mobility of Virtual Machines in Kubernetes clusters: Storage and Cross-Cluster Live Migration
With KubeVirt, Virtual Machines and containers can be managed through a unified Kubernetes control plane. As organizations evolve, they need to upgrade infrastructure without disrupting essential services.
Cross-Cluster Live Migration (CCLM) allows a running VM to be moved seamlessly between the clusters. This enhances flexibility in multi-cluster environments and is especially useful for load balancing, maintenance operations, and infrastructure consolidation – all without interrupting critical workloads.
Storage Live Migration (SLM) allows you to move the VM’s disk data from one storage backend to another while the VM remains running. Rebalancing storage usage, retiring legacy systems, or adopting new storage classes – all without disrupting the applications inside the VM.
Both CCLM and SLM work with any storage backend (including ReadWriteOnce) and require compatible CPU architectures.
After the session, you’ll be ready to migrate your running VMs – across clusters and storage.
