Honestly I think the right fix is to just kill the SCSI passthrough
in virtio.  It has been replaced by virtio-scsi a long time ago, and
has been disabled by default in qemu for a long time (and I don't think
any other hypervisor ever supported it).

It should never have been added (saying that as the person who added it).
