+ * qemu: Add 'sparse' as a new save image format
+
+ QEMU's ``file`` migration has been supplemented with the new stream format
+ ``mapped-ram``, where RAM pages are mapped directly to offsets in the
+ migration file. ``mapped-ram`` is now supported by augmenting the existing
+ save image formats with the ``sparse`` format.
+
+ * qemu: Add support for parallel save/restore
+
+ The ``sparse`` image format can support reading and writing by multiple
+ channels. ``virDomainSaveParams`` and ``virDomainRestoreParams`` now
+ support specifying the number of IO channels used for parallel save and
+ restore. Using multiple channels can reduce the time required to save
+ and restore domains.
