+------------------------
+
+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:
+ #
+ # https://bugs.launchpad.net/nova/+bug/1334398
