39If the backing file is smaller than the snapshot, then the backing file will be
40resized to be the same size as the snapshot. If the snapshot is smaller than
41the backing file, the backing file will not be truncated. If you want the
42backing file to match the size of the smaller snapshot, you can safely truncate
43it yourself once the commit operation successfully completes.

74and via the QMP monitor during the preconfig state. The command is only

494Physical memory dump starting at @var{addr}.
495
496@var{fmt} is a format which tells the command how to format the
497data. Its syntax is: @option{/@{count@}@{format@}@{size@}}
498
499@table @var
500@item count
501is the number of items to be dumped.
502
503@item format
504can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
505c (char) or i (asm instruction).
506
507@item size
508can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
509@code{h} or @code{w} can be specified with the @code{i} format to
510respectively select 16 or 32 bit code instruction size.
511
512@end table

927Bug: can screw up when the buffer contains invalid UTF-8 sequences,
928NUL characters, after the ring buffer lost data, and when reading
929stops because the size limit is reached.
