the kernel-side patch certainly makes sense. I assume that you want the event to propagate up from QEMU to Libvirt and so on? The QEMU patch would need to declare a new event (qapi/misc.json) and send it in handle_event (hw/misc/pvpanic.c). For Libvirt I'm not familiar, so I'm adding the respective list.
Adding an event is fairly easy, if everything you want libvirt to do is report the event to upper layers. I volunteer to do it. Question is, how qemu is going to report this, whether some attributes to GUEST_PANICKED event or some new event.
I think it should be a new event, using GUEST_PANICKED could cause upper layers to react by shutting down or rebooting the guest. Thanks, Paolo
