HXCOMM Use DEFHEADING() to define headings in both help text and rST.
HXCOMM Text between SRST and ERST is copied to the rST version and
HXCOMM discarded from C version.
HXCOMM DEF(command, args, callback, arg_string, help) is used to construct
HXCOMM monitor commands
HXCOMM HXCOMM can be used for comments, discarded from both rST and C.
{
.name = "help|?",
.args_type = "name:S?",
.params = "[cmd]",
.help = "show the help",
.cmd = hmp_help,
.flags = "p",
},
SRST
``help`` or ``?`` [*cmd*]
Show the help for all commands or just for command *cmd*.
ERST
{
.name = "commit",
.args_type = "device:B",
.params = "device|all",
.help = "commit changes to the disk images (if -snapshot is used) or backing files",
.cmd = hmp_commit,
},
SRST
``commit``
Commit changes to the disk images (if -snapshot is used) or backing files.
If the backing file is smaller than the snapshot, then the backing file
will be resized to be the same size as the snapshot. If the snapshot is
smaller than the backing file, the backing file will not be truncated.
If you want the backing file to match the size of the smaller snapshot,
you can safely truncate it yourself once the commit operation successfully
completes.
ERST
{
.name = "quit|q",
.args_type = "",
.params = "",
.help = "quit the emulator",
.cmd = hmp_quit,
.flags = "p",
},
SRST
``quit`` or ``q``
Quit the emulator.
ERST
{
.name = "exit_preconfig",
.args_type = "",
.params = "",
.help = "exit the preconfig state",
.cmd = hmp_exit_preconfig,
.flags = "p",
},
SRST
``exit_preconfig``
This command makes QEMU exit the preconfig state and proceed with
VM initialization using configuration data provided on the command line
and via the QMP monitor during the preconfig state. The command is only
available during the preconfig state (i.e. when the --preconfig command
line option was in use).
ERST
{
.name = "block_resize",
.args_type = "device:B,size:o",
.params = "device size",
.help = "resize a block image",
.cmd = hmp_block_resize,
.coroutine = true,
.flags = "p",
},
SRST
``block_resize``
Resize a block image while a guest is running. Usually requires guest
action to see the updated size. Resize to a lower size is supported,
but should be used with extreme caution. Note that this command only
resizes image files, it can not resize block devices like LVM volumes.
ERST
{
.name = "block_stream",
.args_type = "device:B,speed:o?,base:s?",
.params = "device [speed [base]]",
.help = "copy data from a backing file into a block device",
.cmd = hmp_block_stream,

},
SRST
``block_stream``
Copy data from a backing file into a block device.
ERST
{
.name = "block_job_set_speed",
.args_type = "device:B,speed:o",
.params = "device speed",
.help = "set maximum speed for a background block operation",
.cmd = hmp_block_job_set_speed,
.flags = "p",
},
SRST
``block_job_set_speed``
Set maximum speed for a background block operation.
ERST
{
.name = "block_job_cancel",
.args_type = "force:-f,device:B",
.params = "[-f] device",
.help = "stop an active background block operation (use -f"
"\n\t\t\t if you want to abort the operation immediately"
"\n\t\t\t instead of keep running until data is in sync)",
.cmd = hmp_block_job_cancel,
.flags = "p",
},
SRST
``block_job_cancel``
Stop an active background block operation (streaming, mirroring).
ERST
{
.name = "block_job_complete",
.args_type = "device:B",
.params = "device",
.help = "stop an active background block operation",
.cmd = hmp_block_job_complete,
.flags = "p",
},
SRST
``block_job_complete``
Manually trigger completion of an active background block operation.
For mirroring, this will switch the device to the destination path.
ERST
{
.name = "block_job_pause",
.args_type = "device:B",
.params = "device",
.help = "pause an active background block operation",
.cmd = hmp_block_job_pause,
.flags = "p",
},
SRST
``block_job_pause``
Pause an active block streaming operation.
ERST
{
.name = "block_job_resume",
.args_type = "device:B",
.params = "device",
.help = "resume a paused background block operation",
.cmd = hmp_block_job_resume,

},
SRST
``block_job_resume``
Resume a paused block streaming operation.
ERST
{
.name = "eject",
.args_type = "force:-f,device:B",
.params = "[-f] device",
.help = "eject a removable medium (use -f to force it)",
.cmd = hmp_eject,
},
SRST
``eject [-f]`` *device*
Eject a removable medium (use -f to force it).
ERST
{
.name = "drive_del",
.args_type = "id:B",
.params = "device",
.help = "remove host block device",
.cmd = hmp_drive_del,
},
SRST
``drive_del`` *device*
Remove host block device. The result is that guest generated IO is no longer
submitted against the host device underlying the disk. Once a drive has
been deleted, the QEMU Block layer returns -EIO which results in IO
errors in the guest for applications that are reading/writing to the device.
These errors are always reported to the guest, regardless of the drive's error
actions (drive options rerror, werror).
ERST
{
.name = "change",
.args_type = "device:B,force:-f,target:F,arg:s?,read-only-mode:s?",
.params = "device [-f] filename [format [read-only-mode]]",
.help = "change a removable medium, optional format, use -f to force the operation",
.cmd = hmp_change,
},
SRST
``change`` *device* *setting*
Change the configuration of a device.
``change`` *diskdevice* [-f] *filename* [*format* [*read-only-mode*]]
Change the medium for a removable disk device to point to *filename*. eg::
(qemu) change ide1-cd0 /path/to/some.iso
``-f``
forces the operation even if the guest has locked the tray.
*format* is optional.
*read-only-mode* may be used to change the read-only status of the device.
It accepts the following values:
retain
Retains the current status; this is the default.
read-only
Makes the device read-only.
read-write
Makes the device writable.
``change vnc password`` [*password*]
Change the password associated with the VNC server. If the new password
is not supplied, the monitor will prompt for it to be entered. VNC
passwords are only significant up to 8 letters. eg::
(qemu) change vnc password
Password: ********

``xp /``\ *fmt* *addr*
Physical memory dump starting at *addr*.
*fmt* is a format which tells the command how to format the
data. Its syntax is: ``/{count}{format}{size}``
*count*
is the number of items to be dumped.
*format*
can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
c (char) or i (asm instruction).
*size*
can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
``h`` or ``w`` can be specified with the ``i`` format to
respectively select 16 or 32 bit code instruction size.
Examples:
Dump 10 instructions at the current instruction pointer::
(qemu) x/10i $eip
0x90107063: ret
0x90107064: sti
0x90107065: lea 0x0(%esi,1),%esi
