H A Dbitmaps.rst46 QEMU uses these bitmaps when making incremental backups to know which sections
59 QEMU supports persisting these bitmaps to disk via the qcow2 image format.
61 whereas bitmaps that are not are called "transient".
63 QEMU also supports the migration of both transient bitmaps (tracking any
64 arbitrary image format) or persistent bitmaps (qcow2) via live migration.
79 .. warning:: Transient bitmaps will not be saved on QEMU exit! Persistent
80 bitmaps are available only on qcow2 images.
86 managed bitmaps have a human-readable name chosen by the user at creation
89 - A bitmap's name is unique to the node, but bitmaps attached to different
90 nodes can share the same name. Therefore, all bitmaps are addressed via
