= Understanding live migration
|
|
|
|
Live migration is the process of moving a running virtual machine instance to
|
|
another node in the cluster without interrupting the virtual workload or access.
|
|
This can be a manual process, if you select 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.
|
|
|
|
[IMPORTANT]
|
|
====
|
|
Virtual machines must have a PersistentVolumeClaim (PVC)
|
|
with a shared ReadWriteMany (RWX) access mode to be live migrated.
