Allow certain event types to be rate limited to avoid flooding monitor clients. The monitor_protocol_event() method is changed such that instead of immediately emitting the event to Monitor instances, it will call a new monitor_protocol_event_queue() method. This will check to see if the rate limit for the event has been exceeded, and if so schedule a timer to wakeup at the end of the rate limit period. If further events arrive before the timer fires, the previously queued event will be discarded in favour of the new event. The event will eventually be emitted when the timer fires. This logic is applied to RTC_CHANGE, BALLOON_CHANGE & WATCHDOG events, since the data associated with these events is stateless * monitor.c: Add support for rate limiting * monitor.h: Define monitor_global_init for one-time setup tasks * vl.c: Invoke monitor_global_init * trace-events: Add hooks for monitor event tracing Signed-off-by: NDaniel P.

After setting a balloon target value, applications have to continually poll 'query-balloon' to determine whether the guest has reacted to this request. The virtio-balloon backend knows exactly when the guest has reacted though, and thus it is possible to emit a JSON event to tell the mgmt application whenever the guest balloon changes. This introduces a new 'qemu_balloon_changed()' API which is to be called by balloon driver backends, whenever they have a change in balloon value. This takes the 'actual' balloon value, as would be found in the BalloonInfo struct. The qemu_balloon_change API emits a JSON monitor event which looks like: {"timestamp": {"seconds": 1337162462, "microseconds": 814521}, "event": "BALLOON_CHANGE", "data": {"actual": 944766976}} * balloon.c, balloon.h: Introduce qemu_balloon_changed() for emitting balloon change events on the monitor * hw/virtio-balloon.c: Invoke qemu_balloon_changed() whenever the guest changes the balloon actual value * monitor.c, monitor.h: Define QEVENT_BALLOON_CHANGE Signed-off-by: NDaniel P.

Sometimes it is neccessary for an application to determine whether a particular QMP event is available, so they can decide whether to use compatibility code instead. This introduces a new 'query-events' command to QMP to do just that { "execute": "query-events" } {"return": [{"name": "WAKEUP"}, {"name": "SUSPEND"}, {"name": "DEVICE_TRAY_MOVED"}, {"name": "BLOCK_JOB_CANCELLED"}, {"name": "BLOCK_JOB_COMPLETED"}, ...snip... {"name": "SHUTDOWN"}]} * monitor.c: Turn MonitorEvent -> string conversion into a lookup from a static table of constant strings.

The M type converts from megabytes to bytes. However, the value can be negative before the conversion, which will lead to a flawed conversion. For example, this: (qemu) balloon -1000000000000011 (qemu) Just "works", but the value passed by the balloon command will be something else. This patch fixes this problem by requering a positive value before converting. There's really no reason to accept a negative value for the M type.

It's not checked currently, so something like: (qemu) balloon -100000000000001111114334234 (qemu) Will just "work" (in this case the balloon command will get a random value).

With the acceptance of some new APIs to libspice-server.so it is possible to add support for SPICE to the 'add_client' monitor command, bringing parity with VNC. Since SPICE can use TLS or plain connections, the command also gains a new 'tls' parameter to specify whether TLS should be attempted on the injected client sockets.

Please, note that some of the code supporting memory statistics is still around (eg. virtio_balloon_receive_stats() and reset_stats()).

There are three important remarks in relation to the non-qapi command: 1. This commit also fixes the behavior of the 'query-vnc' and 'info vnc' commands to return an error when qemu is built without VNC support (ie. --disable-vnc). The non-qapi command would return the OK response in QMP and no response in HMP 2. The qapi version explicitly marks the fields 'host', 'family', 'service' and 'auth' as optional. Their are not documented as optional in the non-qapi command doc, but they would not be returned if vnc support is disabled. The qapi version maintains the same semantics, but documents those fields correctly 3. The 'clients' field, which is a list, is marked as optional but is always returned. If there are no clients connected an empty list is returned. This is not the Right Way to this in the qapi but it's how the non-qapi command used to work Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com> Signed-off-by: NLuiz Capitulino <lcapitulino@redhat.com>
