How about adding a flag that tells QEMU whether to pause or reboot the guest after the panic? We cannot assume that we always have a management layer that takes care of this. One example is Microsoft's WHQL that deliberately generates a BSOD, and then examines the dump files. Ronen. On

Well, we want to support Microsoft's VSS, and that requires a guest agent that communicates with all the writers (applications), waiting for them to flush their app data in order to generate a consistent app-level snapshot. The VSS platform does most of the work. Still, at the bottom line, the
