Great, thanks! Can you please post a backtrace?
The easiest way is:
$ ulimit -c unlimited
$ qemu-system-x86_64 -enable-kvm -m 1024 ...
...crash...
$ gdb -c qemu-system-x86_64.core
(gdb) bt
Depending on how your system is configured the core file might have a
different filename but there should be a file name *core* the current
working directory after the crash.
The backtrace will make it possible to find out where the crash
occurred.
Thanks,
Stefan
