Actually, I sort of like this approach more in some You would need to add support for the dynamic sysbus device allocation in the spapr machine, but then I don't see why it wouldn't work. PCI however is the more natural choice on sPAPR if you want to do virtio. That said, if all you need is a chr transport, IIRC there should be a way to get you additional channels on the existing "serial port" - which really is just a simply hypercall interface. But David is the best person to guide you to the best path forward here. Alex > respects though, as it doesn't require a special testdev or virtio > support, keeping the unit test extra minimal.
