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? Regards, Halil
