Ah, sorry, I meant a core file produced when qemu-dm crashes (that is,
assuming that qemu-dm does crash, which appears likely). All the log files
tell us is that xend thinks that qemu-dm process simply disappeared without
warning. The question is obviously: why did it disappear, and only for you
in your setup.
