Don't use printf for debugging instrumentation. When doing quick
hacking, can use fprintf(stderr, and take your prints from stderr. If
you are looking for something more correct then you should consider
using qemu_log_mask with one of the log options. Then you can access
your prints either from stderr or log them to file with -D option.
