+      Offline migration transfers inactive definition of a domain (which
+      may or may not be active). After successful completion, the domain
+      remains in its current state on source host and is defined but
+      inactive on destination host. It's a bit more clever than
+      <code>virsh dumpxml</code> on source host followed by
+      <code>virsh define</code> on destination host, as offline migration
+      will run pre-migration hook to update the domain XML on destination
+      host. Currently, copying non-shared storage is not supported during
+      offline migration.
