When you say "virtio-net driver" I think you mean the virtio-net device emulation code in QEMU? These *are* the properties that can be set from the QEMU command-line. For example: -device virtio-net-pci,csum=off The command-line -device option creates device objects using qdev_device_add() and then loops over the command-line parameters calling set_property() on them. Hope this helps you understand the code. Stefan
