HXCOMM Use DEFHEADING() to define headings in both help text and texi HXCOMM Text between STEXI and ETEXI are copied to texi version and HXCOMM discarded from C version HXCOMM Text between SQMP and EQMP is copied to the QMP documention file and HXCOMM does not show up in the other formats. 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 texi and C SQMP QMP Supported Commands ---------------------- This document describes all commands currently supported by QMP. Most of the time their usage is exactly the same as in the user Monitor, this means that any other document which also describe commands (the manpage, QEMU's manual, etc) can and should be consulted. QMP has two types of commands: regular and query commands. Regular commands usually change the Virtual Machine's state someway, while query commands just return information. The sections below are divided accordingly. It's important to observe that all communication examples are formatted in a reader-friendly way, so that they're easier to understand. However, in real protocol usage, they're emitted as a single line. Also, the following notation is used to denote data flow: -> data issued by the Client <- Server data response Please, refer to the QMP specification (QMP/qmp-spec.txt) for detailed information on the Server command and response formats. NOTE: This document is temporary and will be replaced soon. 1. Stability Considerations =========================== The current QMP command set (described in this file) may be useful for a number of use cases, however it's limited and several commands have bad defined semantics, specially with regard to command completion. These problems are going to be solved incrementally in the next QEMU releases and we're going to establish a deprecation policy for badly defined commands. If you're planning to adopt QMP, please observe the following: 1. The deprecation policy will take efect and be documented soon, please check the documentation of each used command as soon as a new release of QEMU is available 2. DO NOT rely on anything which is not explicit documented 3. Errors, in special, are not documented. Applications should NOT check for specific errors classes or data (it's strongly recommended to only check for the "error" key) 2. Regular Commands =================== Server's responses in the examples below are always a success response, please refer to the QMP specification for more details on error responses.

When the request completes a json-object will be returned containing the following data: - "actual": current balloon value in bytes (json-int) - "mem_swapped_in": Amount of memory swapped in bytes (json-int, optional) - "mem_swapped_out": Amount of memory swapped out in bytes (json-int, optional) - "major_page_faults": Number of major faults (json-int, optional) - "minor_page_faults": Number of minor faults (json-int, optional) - "free_mem": Total amount of free and unused memory in bytes (json-int, optional) - "total_mem": Total amount of available memory in bytes (json-int, optional) Example: -> { "execute": "query-balloon" } <- { "return":{ "actual":1073741824, "mem_swapped_in":0, "mem_swapped_out":0, "major_page_faults":142, "minor_page_faults":239245, "free_mem":1014185984, "total_mem":1044668416 } } EQMP STEXI @item info qtree show device tree @item info qdm show qdev device model list @item info roms show roms @end table ETEXI HXCOMM DO NOT add new commands after 'info', move your addition before it! #if defined(CONFIG_SPICE) { .name = "spice_migrate_info", .args_type = "hostname:s,port:i?,tls-port:i?,cert-subject:s?", .params = "hostname port tls-port cert-subject", .help = "send migration info to spice client", .user_print = monitor_user_noop, .mhandler.cmd_new = mon_spice_migrate, }, #endif STEXI @end table ETEXI
