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
