3 # = Introduction
4 #
5 # This document describes all commands currently supported by QMP.
6 #
7 # Most of the time their usage is exactly the same as in the user Monitor, this
8 # means that any other document which also describe commands (the manpage,
9 # QEMU's manual, etc) can and should be consulted.
10 #
11 # QMP has two types of commands: regular and query commands. Regular commands
12 # usually change the Virtual Machine's state someway, while query commands just
13 # return information. The sections below are divided accordingly.
14 #
15 # It's important to observe that all communication examples are formatted in
16 # a reader-friendly way, so that they're easier to understand. However, in real
17 # protocol usage, they're emitted as a single line.
18 #
19 # Also, the following notation is used to denote data flow:
20 #
21 # Example:
22 #
23 # | -> data issued by the Client
24 # | <- Server data response
25 #
26 # Please, refer to the QMP specification (docs/interop/qmp-spec.txt) for
27 # detailed information on the Server command and response formats.
28 #
29 # = Stability Considerations
30 #
31 # The current QMP command set (described in this file) may be useful for a
32 # number of use cases, however it's limited and several commands have bad
33 # defined semantics, specially with regard to command completion.
34 #
35 # These problems are going to be solved incrementally in the next QEMU releases
36 # and we're going to establish a deprecation policy for badly defined commands.
37 #
38 # If you're planning to adopt QMP, please observe the following:
39 #
40 # 1. The deprecation policy will take effect and be documented soon, please
41 # check the documentation of each used command as soon as a new release of
42 # QEMU is available
43 #
44 # 2. DO NOT rely on anything which is not explicit documented
45 #
46 # 3. Errors, in special, are not documented. Applications should NOT check
47 # for specific errors classes or data (it's strongly recommended to only
48 # check for the "error" key)

1294 #
1295 # This command will get a property from a object model path and return the
1296 # value.
1297 #
1298 # @path: The path within the object model. There are two forms of supported
1299 # paths--absolute and partial paths.
1300 #
1301 # Absolute paths are derived from the root object and can follow child<>
1302 # or link<> properties. Since they can follow link<> properties, they
1303 # can be arbitrarily long. Absolute paths look like absolute filenames
1304 # and are prefixed with a leading slash.
1305 #
1306 # Partial paths look like relative filenames. They do not begin
1307 # with a prefix. The matching rules for partial paths are subtle but
1308 # designed to make specifying objects easy. At each level of the
1309 # composition tree, the partial path is matched as an absolute path.
1310 # The first match is not returned. At least two matches are searched
1311 # for. A successful result is only returned if only one match is
1312 # found. If more than one match is found, a flag is return to
1313 # indicate that the match was ambiguous.
1314 #
1315 # @property: The property name to read

1319 # pathnames. All integer property types (u8, u16, etc) are
1320 # returned as #int.

1358 # @arg: If @device is a block device, then this is an optional format to open

1601 # of RAM. This can happen for a large guest, or a

1607 # memory, which cannot be trusted
1608 # 2. The guest can be in real-mode even if paging is enabled. For
