Thinking about Sasha's patches, we can reduce ring usage for virtio net small packets dramatically if we put virtio net header inline with the data. This can be done for free in case guest net stack allocated extra head room for the packet, and I don't see why would this have any downsides. Even though with my recent patches qemu no longer requires header to be the first s/g element, we

This is on top of Paolo and Nick's work. Current status: Works now (guest boots fine, no hang any more) with seabios's virtio-scsi disabled. Rebased to latest qemu.org/master Change details are in commit log. TODO: Make seabios happy.
