* **Bug fixes**
+ * qemu: Fix disk quiescing rollback when creating external snapshots
+
+ If the qemu guest agent call to freeze filesystems failed when creating
+ an external snapshot with ``VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE`` flag the
+ filesystems would be unconditionally thawed. This could cause problems when
+ the filesystems were frozen by an explicit call to ``virDomainFSFreeze``
+ since the guest agent then rejects any further freeze attempts once are
+ filesystems frozen, an explicit freeze followed by a quiesced snapshot
+ would fail and thaw filesystems.
+
+ Users are also encouraged to use ``virDomainFSFreeze/Thaw`` manually instead
+ of relying on ``VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE`` if they need finer
+ grained control.
