Let's enable revision 1 for virtio-ccw devices. We can always offer VERSION_1 as drivers in legacy mode won't be able to see it anyway. We have to introduce a way to set a lower maximum revision for a device to accommodate the following cases: - compat machines (to enforce legacy only) - virtio-blk with scsi support (version 1 + scsi is fenced by common code, with a user-configured max revision of 0 we can allow scsi via not offering VERSION_1) Signed-off-by: NCornelia Huck <cornelia.huck@de.ibm.com> Reviewed-by: NMichael S.
