[libvirt] [Question]Libvirt doesn't care about qemu monitor event if fail to destroy qemu process

Hi, We unregister qemu monitor after sending QEMU_PROCESS_EVENT_MONITOR_EOF to workerPool: static void qemuProcessHandleMonitorEOF(qemuMonitorPtr mon, virDomainObjPtr vm, void *opaque) { virQEMUDriverPtr driver = opaque; qemuDomainObjPrivatePtr priv; struct qemuProcessEvent *processEvent; ... processEvent->eventType = QEMU_PROCESS_EVENT_MONITOR_EOF; processEvent->vm = vm; virObjectRef(vm); if (virThreadPoolSendJob(driver->workerPool, 0, processEvent) < 0) { ignore_value(virObjectUnref(vm)); VIR_FREE(processEvent); goto cleanup; } /* We don't want this EOF handler to be called over and over while the * thread is waiting for a job. */ qemuMonitorUnregister(mon); ... } Then we handle QEMU_PROCESS_EVENT_MONITOR_EOF in processMonitorEOFEvent function: static void processMonitorEOFEvent(virQEMUDriverPtr driver, virDomainObjPtr vm) { ... if (qemuProcessBeginStopJob(driver, vm, QEMU_JOB_DESTROY, true) < 0) return; ... } Here, libvirt will show that the vm state is running all the time if qemuProcessBeginStopJob return -1 even though qemu may terminate or be killed later. So, may be we should re-register the monitor when qemuProcessBeginStopJob failed? Thanks, Zongyong Wu
