2012-08-13qapi: add query-cpu-definitions command (v2)Anthony Liguori
This command attempts to map to the behavior of -cpu ?. Unfortunately, the output of this command differs wildly across targets. To accommodate this, we use a weak symbol to implement a default version of the command that fails with a QERR_NOT_SUPPORTED error code. Targets can then override and implement this command if it makes sense for them. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

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>
2012-08-13qmp: don't emit the RESET event on wakeup from S3Luiz Capitulino
QEMU is basically using reset logic when waking up from S3. This causes the QMP RESET event to be emitted, which is wrong. Also, the runstate checks done in reset are not necessary for S3 wakeup. Fix this by untangling wakeup from reset logic and passing VMRESET_SILENT to qemu_system_reset() to avoid emitting the RESET event.

2012-08-13scripts: qapi-commands.py: qmp-commands.h: include qdict.hLuiz Capitulino
qmp-commands.h declares several functions that have arguments of type QDict. However, qdict.h is not included. This will cause a build breakage when a file includes qmp-commands.h but doesn't include qdict.h. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

2012-08-13error, qerror: pass desc string to error callsLuiz Capitulino
This commit changes all QERR_ macros to contain a human message (ie. the desc string found in qerr_table[]) instead of a json dictionary in string format. Before this commit, error_set() and qerror_report() would receive a json dictionary in string format and build a qobject from it. Now, both function receive a human message instead and the qobject is not built anymore. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com>

2012-08-13qemu-ga: switch to the new error format on the wireLuiz Capitulino
IMPORTANT: this BREAKS qemu-ga compatibility for the error response. Instead of returning something like: { "error": { "class": "InvalidParameterValue", "data": {"name": "mode", "expected": "halt|powerdown|reboot" } } } qemu-ga now returns: { "error": { "class": "GenericError", "desc": "Parameter 'mode' expects halt|powerdown|reboot" } } Notice that this is also a bug fix, as qemu-ga wasn't returning the human message.

2012-08-13qmp: switch to the new error format on the wireLuiz Capitulino
IMPORTANT: this BREAKS QMP's compatibility for the error response. This commit changes QMP's wire protocol to make use of the simpler error format introduced by previous commits. There are two important (and mostly incompatible) changes: 1. Almost all error classes have been replaced by GenericError. The only classes that are still supported for compatibility with libvirt are: CommandNotFound, DeviceNotActive, KVMMissingCap, DeviceNotFound and MigrationExpected 2. The 'data' field of the error dictionary is gone As an example, an error response like: { "error": { "class": "DeviceNotRemovable", "data": { "device": "virtio0" }, "desc": "Device 'virtio0' is not removable" } } Will now be emitted as: { "error": { "class": "GenericError", "desc": "Device 'virtio0' is not removable" } } Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com>

2012-08-13qerror: add proper ErrorClass value for QERR_ macrosLuiz Capitulino
This commit replaces the place holder value for the ErrorClass argument with a proper ErrorClass value for all QERR_ macros.

2012-08-13error, qerror: add ErrorClass argument to error functionsLuiz Capitulino
The new argument is added to functions qerror_report() and error_set(). It's stored in Error and QError. qerror_report_err() is also updated to take care of it. The QERR_ macros are changed to contain a place holder value for the new argument, so that the value is used on all current calls to qerror_report() and error_set() (and also to initialize qerror_table[]).

2012-08-13migration: don't rely on any QERR_SOCKET_*Luiz Capitulino
Use the in_progress argument for QERR_SOCKET_CONNECT_IN_PROGRESS. The other errors are handled the same by checking if the error is set and then calling migrate_fd_error() if it's. It's also necessary to change inet_connect_opts() not to set QERR_SOCKET_CONNECT_IN_PROGRESS. This error is only used by tcp_start_outgoing_migration() and not changing it along with the usage of in_progress would break migration. Furthermore this commit fixes a bug. Today, there's a spurious error report when migration succeeds: (qemu) migrate tcp:0:4444 migrate: Connection can not be completed immediately (qemu) After this commit no spurious error is reported anymore.
