Please post your full QEMU command-line. Did you enable core dumps before launch QEMU? Do "ulimit -c unlimited" in the same shell before running the QEMU command-line. If it is exiting instead of crashing I suggest launching QEMU from gdb and catching the exit: 1. Install qemu-kvm-dbg to get the debuginfo for useful backtraces 2. Start gdb with QEMU and its usual command-line arguments: gdb --args qemu-kvm ... 3. Set breakpoints on exit(3) and abort(2): b exit b abort 4. Run the VM and reproduce the exit: r 5. When it exits you will hopefully be at an exit/abort breakpoint and can print the stack trace: bt Please post the backtrace so we have more information on how the exit happens. Thanks, Stefan
