Understanding live migration

Live migration is the process of moving a running virtual machine instance to another node in the cluster without interruption to the virtual workload or access. This can be a manual process, if you select a virtual machine instance to migrate to another node, or an automatic process, if the virtual machine instance has a LiveMigrate eviction strategy and the node on which it is running is placed into maintenance.

Virtual machines must have a PersistentVolumeClaim (PVC) with a shared ReadWriteMany (RWX) access mode to be live migrated.
