Could it be that this is a results of compiling qemu with --enable-debug
to get debugging symbols?

Yes.
*urg* my fault - sorry. Is there a way to get debugging symbols without
using enable-debug / getting slower performance?

Yes, just do nothing ("--enable-debug-info" is the default;
"--enable-debug" enables debug info _and_ turns off optimization).

If I do not enable-debug dh_strip does not extract any debugging symbols.

Maybe you forgot --disable-strip?

Thanks!

Stefan
