Tested using QEMU command line option:
"-device virtio-scsi-pci,id=scsi0,bus=pci.0,addr=0x4,
iommu_platform=on,disable-modern=off,disable-legacy=on"
and
"-device virtio-blk-pci,scsi=off,bus=pci.0,
addr=0x5,drive=drive-virtio-disk0,id=virtio-disk0,
iommu_platform=on,disable-modern=off,disable-legacy=on"
