The sun4u machine has an IOMMU and therefore it is possible to program it such that the virtio-device IOVA does not map directly to the CPU physical address. This is not a problem with Linux which always maps the IOVA directly to the CPU physical address, however it is required for the NetBSD virtio driver where this is not the case. Set the sun4u machine defaults for all virtio devices so that disable-legacy=on and iommu_platform=on to ensure a default configuration will allow virtio devices to function correctly on both Linux and NetBSD.
