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. | |

85 | Resize a block image while a guest is running. Usually requires guest | |

87 | but should be used with extreme caution. Note that this command only | |
88 | resizes image files, it can not resize block devices like LVM volumes. | |

461 | ``xp /``\ *fmt* *addr* | |
462 | Physical memory dump starting at *addr*. | |
463 | ||
464 | *fmt* is a format which tells the command how to format the | |
465 | data. Its syntax is: ``/{count}{format}{size}`` | |
466 | ||
467 | *count* | |
468 | is the number of items to be dumped. | |
469 | *format* | |
470 | can be x (hex), d (signed decimal), u (unsigned decimal), o (octal), | |
471 | c (char) or i (asm instruction). | |
472 | *size* | |
473 | can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86, | |
474 | ``h`` or ``w`` can be specified with the ``i`` format to | |
475 | respectively select 16 or 32 bit code instruction size. | |
476 | ||
477 | Examples: | |
478 | ||
479 | Dump 10 instructions at the current instruction pointer:: | |
480 | ||
481 | (qemu) x/10i $eip | |
