Hi all, As we know, when hot-add a device, we don't know whether the device is present in VM from outside(like libvirt). However, unplugging device, when complete remove the device, Qemu will generate a Monitor event,QEVENT_DEVICE_DELETED. Libvirt can receive the event and do something. So is it necessary to add a Monitor event of completing add device such as QEVENT_DEVICE_ADDED.
