+------------------------
+
+Live snapshotting is disabled by default in nova. To enable this, it needs a manual switch.
+
+From manual:
+
+.. code-block:: yaml
+
+  # When using libvirt 1.2.2 live snapshots fail intermittently under load
+  # (likely related to concurrent libvirt/qemu operations). This config
+  # option provides a mechanism to disable live snapshot, in favor of cold
+  # snapshot, while this is resolved. Cold snapshot causes an instance
+  # outage while the guest is going through the snapshotting process.
+  #
+  # For more information, refer to the bug report:
