32 | ``commit`` | |
33 | Commit changes to the disk images (if -snapshot is used) or backing files. | |
34 | If the backing file is smaller than the snapshot, then the backing file | |
35 | will be resized to be the same size as the snapshot. If the snapshot is | |
36 | smaller than the backing file, the backing file will not be truncated. | |
37 | If you want the backing file to match the size of the smaller snapshot, | |
38 | you can safely truncate it yourself once the commit operation successfully | |
39 | completes. | |

66 | ``exit_preconfig`` | |
67 | This command makes QEMU exit the preconfig state and proceed with | |
68 | VM initialization using configuration data provided on the command line | |
69 | and via the QMP monitor during the preconfig state. The command is only | |
70 | available during the preconfig state (i.e. when the --preconfig command | |
71 | line option was in use). | |

87 | but should be used with extreme caution. Note that this command only | |

465 | *fmt* is a format which tells the command how to format the | |

467 | ||
468 | *count* | |
469 | is the number of items to be dumped. | |
470 | *format* | |
471 | can be x (hex), d (signed decimal), u (unsigned decimal), o (octal), | |
472 | c (char) or i (asm instruction). | |
473 | *size* | |
474 | can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86, | |
475 | ``h`` or ``w`` can be specified with the ``i`` format to | |
476 | respectively select 16 or 32 bit code instruction size. | |
