Resize a block image while a guest is running. Usually requires guest |
68 |
action to see the updated size. Resize to a lower size is supported, |
69 |
but should be used with extreme caution. Note that this command only |
70 |
resizes image files, it can not resize block devices like LVM volumes. |

101 |
Remove host block device. The result is that guest generated IO is no longer |
102 |
submitted against the host device underlying the disk. Once a drive has |
103 |
been deleted, the QEMU Block layer returns -EIO which results in IO |
104 |
errors in the guest for applications that are reading/writing to the device. |

@example |
127 |
(qemu) change ide1-cd0 /path/to/some.iso |

138 |
@end example |
139 |
|

@item change vnc password [@var{password}] |
141 |
|
142 |
Change the password associated with the VNC server. If the new password is not |

Send @var{keys} to the emulator. @var{keys} could be the name of the |
466 |
key or @code{#} followed by the raw value in either decimal or hexadecimal |
467 |
format. Use @code{-} to press several keys simultaneously. Example: |
468 |
@example |
469 |
sendkey ctrl-alt-f1 |
470 |
@end example |
471 |
|
472 |
This command is useful to send keys that your graphical user interface |
473 |
intercepts at low level, such as @code{ctrl-alt-f1} in X Window. |
