With old releases, I wanted to say any QEMU that is still supported by
us ;). For upstream it is backport to the stable versions currently in
support.

The commit message does not tell us if this is an enhancement or a
bugfix, stable is not mentioned, and neither do we get the information
since when is this problem existent. I simply wanted to have that
discussion.

Would it make sense to split this up into a virtio-ccw a css and a 3270
patch? That way if there was a problem with let's say 3270, we could
still keep the other two?
