2013-03-26qmp: add path to device_deleted eventMichael S. Tsirkin
Add QOM path to device deleted event. It now becomes useful to report it for devices which don't have an ID assigned. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2013-03-17qdev: DEVICE_DELETED eventMichael S. Tsirkin
libvirt has a long-standing bug: when removing the device, it can request removal but does not know when the removal completes. Add an event so we can fix this in a robust way. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2012-10-24block: introduce BLOCK_JOB_READY eventPaolo Bonzini
Even for jobs that need to be manually completed, management may want to take care itself of the completion, not requiring the user to issue a command to terminate the job. In this case we want to avoid that they poll us continuously, waiting for completion to become available. Thus, add a new event that signals the phase switch and the availability of the block-job-complete command.

2012-09-28block: introduce block job errorPaolo Bonzini
The following behaviors are possible: 'report': The behavior is the same as in 1.1. An I/O error, respectively during a read or a write, will complete the job immediately with an error code. 'ignore': An I/O error, respectively during a read or a write, will be ignored. For streaming, the job will complete with an error and the backing file will be left in place. For mirroring, the sector will be marked again as dirty and re-examined later. 'stop': The job will be paused and the job iostatus will be set to failed or nospace, while the VM will keep running. This can only be specified if the block device has rerror=stop and werror=stop or enospc. 'enospc': Behaves as 'stop' for ENOSPC errors, 'report' for others. In all cases, even for 'report', the I/O error is reported as a QMP event BLOCK_JOB_ERROR, with the same arguments as BLOCK_IO_ERROR. It is possible that while stopping the VM a BLOCK_IO_ERROR event will be reported and will clobber the event from BLOCK_JOB_ERROR, or vice versa. This is not really avoidable since stopping the VM completes all pending I/O requests. In fact, it is already possible now that a series of BLOCK_IO_ERROR events are reported with rerror=stop, because vm_stop calls bdrv_drain_all and this can generate further errors.

2012-09-28QAPI: add command for live block commit, 'block-commit'Jeff Cody
The command for live block commit is added, which has the following arguments: device: the block device to perform the commit on (mandatory) base: the base image to commit into; optional (if not specified, it is the underlying original image) top: the top image of the commit - all data from inside top down to base will be committed into base (mandatory for now; see note, below) speed: maximum speed, in bytes/sec Note: Eventually this command will support merging down the active layer, but that code is not yet complete. If the active layer is passed in as top, then an error will be returned. Once merging down the active layer is supported, the 'top' argument may become optional, and default to the active layer. The is done as a block job, so upon completion a BLOCK_JOB_COMPLETED will be emitted.

2012-08-13qmp: add SUSPEND_DISK eventLuiz Capitulino
Emitted when the guest makes a request to enter S4 state. There are three possible ways of having this event, as described here: http://lists.gnu.org/archive/html/qemu-devel/2012-07/msg02307.html I've decided to add a new event and make it indepedent of SHUTDOWN. This means that the SHUTDOWN event will eventually follow the SUSPEND_DISK event. I've choosen this way because of two reasons: 1. Having an indepedent event makes it possible to query for its existence by using query-events 2. In the future, we may allow the user to change what QEMU should do as a result of the guest entering S4. So it's a good idea to keep both events separated Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

2012-08-13qmp: emit the WAKEUP event when the guest is put to runLuiz Capitulino
Today, the WAKEUP event is emitted when a wakeup _request_ is made. This could be the system_wakeup command, for example. A better semantic would be to emit the event when the guest is already running, as that's what matters in the end. This commit does that change. In theory, this could break compatibility. In practice, it shouldn't happen though, as clients shouldn't rely on timing characteristics of the events. That is, a client relying that the guest is not running when the event arrives may break if the event arrives after the guest is already running. This commit also adds the missing documentation for the WAKEUP event. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com>
2012-06-15Add event notification for guest balloon changesDaniel P. Berrange
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: Daniel P.

2010-12-09spice: connection events.Gerd Hoffmann
This patch adds support for connection events to spice. The events are quite simliar to the vnc events. Unlike vnc spice uses multiple tcp channels though. qemu will report every single tcp connection (aka spice channel). If you want track spice sessions only you can filter for the main channel (channel-type == 1). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
