Just using -cdrom isn't likely to work. I'd expect that you need
a collection of -device options to set up some virtio devices or
possibly some other PCI device that you can then eventually
plug the ISO image into via -drive.

libvirt knows how to attach CDROM images to a virt board setup,
so you could look at how it does it.

PS: I suggest you use the virtio-net-pci device rather than
virtio-net-device which will be virtio-mmio, unless your guest
can't cope with PCI for some reason.
