Next time ensure that core dumps are enabled:
$ ulimit -c unlimited  # enable core dumps
$ qemu-kvm ...

If it crashes you'll have a core file that the gdb debugger can process.

It's also worth checking dmesg(1) output to see if your system ran out
of memory and the kernel killed the qemu-kvm process to free memory.

Hope this helps,
