[libvirt] [PATCHv2] qemu: Try to use QMP for send-key if supported

Instead of always using HMP use the QMP send-key command introduced in qemu 1.3. --- Notes: Version 2: - always try QMP instead of adding capability bit src/qemu/qemu_monitor_json.c | 69 ++++++++++++++++++++++++++++++++++++++++---- 1 file changed, 64 insertions(+), 5 deletions(-) diff --git a/src/qemu/qemu_monitor_json.c b/src/qemu/qemu_monitor_json.c index 1bf8baf..759198b 100644 --- a/src/qemu/qemu_monitor_json.c +++ b/src/qemu/qemu_monitor_json.c @@ -3372,11 +3372,70 @@ int qemuMonitorJSONSendKey(qemuMonitorPtr mon, unsigned int *keycodes, unsigned int nkeycodes) { - /* - * FIXME: qmp sendkey has not been implemented yet, - * and qmp API of it cannot be anticipated, so we use hmp temporary. - */ - return qemuMonitorTextSendKey(mon, holdtime, keycodes, nkeycodes); + int ret = -1; + virJSONValuePtr cmd = NULL; + virJSONValuePtr reply = NULL; + virJSONValuePtr keys = NULL; + virJSONValuePtr key = NULL; + unsigned int i; + + /* create the key data array */ + if (!(keys = virJSONValueNewArray())) + goto no_memory; + + for (i = 0; i < nkeycodes; i++) { + if (keycodes[i] > 0xffff) { + virReportError(VIR_ERR_OPERATION_FAILED, + _("keycode %d is invalid: 0x%X"), i, keycodes[i]); + goto cleanup; + } + + /* create single key object */ + if (!(key = virJSONValueNewObject())) + goto no_memory; + + /* Union KeyValue has two, types, use the generic one */ + if (virJSONValueObjectAppendString(key, "type", "number") < 0) + goto no_memory; + + /* with the keycode */ + if (virJSONValueObjectAppendNumberInt(key, "data", keycodes[i]) < 0) + goto no_memory; + + if (virJSONValueArrayAppend(keys, key) < 0) + goto no_memory; + + key = NULL; + + } + + cmd = qemuMonitorJSONMakeCommand("send-key", + "a:keys", keys, + holdtime ?
