Not sure: We don't have 2.3 compat for ccw... but would give a better template for later changes.

Yes. But this can be an addon patch. Lets keep this patch as is to have scsi=off as default for virtio 1.0 (some iotests do fail because of this) Christian

Devices that are compliant with virtio-1 do not support scsi passthrough any more (and it has not been a recommended setup anyway for quite some time). To avoid having to switch it off explicitly in newer qemus that turn on virtio-1 by default, let's switch the default to scsi=false for 2.5.
