Return a QDict, which may contain up to more two QDicts, depending on the type of migration we're performing. IMPORTANT: as a QInt stores a int64_t integer, RAM values are going to be stored as int64_t and not as uint64_t as they are today. If this is a problem QInt will have to be changed.

When using encrypted disk images, QEMU will prompt the user for passwords when started. This makes sense for the user protocol, but doesn't for QMP. The solution is to have Monitor command which allows the user or a Client to set passwords in advance, so that we avoid the prompt completely. This is what block_passwd does, for example: (QEMU) block_passwd ide0-hd0 foobar Signed-off-by: NLuiz Capitulino <lcapitulino@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

We still have handlers which will call monitor print functions in several places. Usually to report errors. If they do this when we are in control mode, we will be emitting garbage to our clients. To avoid this problem, this commit adds a way to disable those functions. If any of them is called when in control mode, we will emit a generic error. Although this is far from the perfect solution, it guarantees that only JSON is sent to Clients.

Asynchronous events are generated with a call to monitor_protocol_event(). This function builds the right data-type and emit the event right away. The emitted data is always a JSON object and its format is as follows: { "event": json-string, "timestamp": { "seconds": json-number, "microseconds": json-number }, "data": json-value } This design is based on ideas by Amit Shah <amit.shah@redhat.com>.

The 'info' command makes sense for the user protocol, but for QMP it doesn't, as its return data is not well defined. That is, it can return anything. To fix this Avi proposes having 'query-' commands when in protocol mode. For example, 'info balloon' would become 'query-balloon'. The right way of supporting this would probably be to move all info handlers to qemu-monitor.hx, add a flags field to mon_cmd_t to identify them and then modify do_info() to do its search based on that flag. Unfortunately, this would require a big change in the Monitor. To make things simpler for now, this commit takes a different approach: a check for commands starting with "query-" is added to toplevel QMP code, if it's true we setup things so that do_info() is called with the appropriate arguments. This is a hack, but is a temporary one and guarantees that query- commands will work from the first day. Also note that 'info' is not allowed in protocol mode.

The JSON stream parser is used to do QMP input. When there are enough characters to be parsed it calls Monitor's handle_qmp_command() function to handle the input. This function's job is to check if the input is correct and call the appropriate handler. In other words, it does for QMP what handle_user_command() does for the user protocol. This means that handle_qmp_command() also has to parse the (ugly) "args_type" format to able to get the arguments names and types expected by the handler. The format to input commands in QMP is as follows: { "execute": json-string, "id": json-value, "arguments": json-object } Please, note that this commit also adds "id" support.

In the new Monitor output is always performed by only two functions: do_info() and monitor_call_handler(). To support QMP output, we modify those functions to check if we are in control mode. If so, we call monitor_protocol_emitter() to emit QMP output, otherwise we do regular output. QMP has two types of responses to issued commands: success and error. The outputed data is always a JSON object. Success responses have the following format: { "return": json-value, "id": json-value } Error responses have the following format: { "error": { "class": json-string, "desc": json-string, "data": json-value } "id": json-value } Please, note that the "id" key is part of the input code, and thus is not added in this commit.

This commit adds initial QMP support in QEMU. It's important to notice that most QMP code will be part of the Monitor. Input will be read by monitor_control_read(). Currently it does nothing but next patches will add proper input support. The function monitor_json_emitter(), as its name implies, is used by the Monitor to emit JSON output. In this commit it's used by monitor_control_event() to print our greeting message. Finally, control mode support is also added to monitor_init(), allowing QMP to be really enabled.

This commit adds a flag called 'control' to the '-monitor' command-line option. This flag enables control mode. The syntax is: qemu [...] -monitor control,<device> Where <device> is a chardev (excluding 'vc', for obvious reasons). For example: $ qemu [...] -monitor control,tcp:localhost:4444,server Will run QEMU in control mode, waiting for a client TCP connection on localhost port 4444. NOTE: I've tried using QemuOpts for this, but turns out that it will try to parse the device part, which should be untouched.

This commit adds QError support in the Monitor. A QError member is added to the Monitor struct. This new member stores error information and is also used to check if an error has occurred when the called handler returns. Additionally, a new macro called qemu_error_new() is introduced. It builds on top of the QemuErrorSink API and should be used in place of qemu_error(). When all conversion to qemu_error_new() is done, qemu_error() can be turned private. Basically, Monitor's error flow is something like this: 1. An error occurs in the handler, it calls qemu_error_new() 2. qemu_error_new() builds a new QError object and stores it in the Monitor struct 3. The handler returns 4. Top level Monitor code checks the Monitor struct and calls qerror_print() to print the error Signed-off-by: NLuiz Capitulino <lcapitulino@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>
