In order to prevent QEMU from automatically opening an image's backing
chain, use ``"backing": null'' instead.
address@hidden rbd keyvalue pair encoded filenames: "" (since 3.1.0)
+
+Options for ``rbd'' should be specified according to its runtime options,
+like other block drivers. Legacy parsing of keyvalue pair encoded
+filenames is useful to open images with the old format for backing files;
+These image files should be updated to use the current format.
+
+Example of legacy encoding:
+
address@hidden:@{"file.driver":"rbd", "file.filename":"rbd:rbd/name"@}}
+
+The above, converted to the current supported format:
+
address@hidden:@{"file.driver":"rbd", "file.pool":"rbd", "file.image":"name"@}}
