Alex, Andreas, here is an implementation for a soft-reset variant that is used by s390 on kdump. The last patch also wires up the nmi command to inject a restart interrupt. So there are two methods to trigger kdump: - a crash, e.g. via echo c > /proc/sysrq_trigger - inject-nmi /nmi via virsh/monitor
