sorry for the late reply, I could not access my eMail during
the last couple of days. Patches are on top of
790f0b3057787bb64, I did not realise that this one was only
in the middle of qemu refactoring, not at the end :-(

Do you plan any more refactorings to the qemu base in the near
future, and if yes, are these already available somewhere? I'd
like to avoid another useless rebase...

Thanks, Wolfgang
