I already have a working patch series with 6 patches to fix these
issues. I wrote them in the last two days, which means they are not yet
in a reviewable state and the series is too big for 8.2. I think I need
another weekend or two before I send them to the qemu-devel mailing list.
With best regards,
Volker
