IOW, I can envision a model that looked like PCI -> virtio-pci -> virtio-shm -> virtio-ring -> virtio-net
Let me stress that what's important here is that devices target either virtio-ring or virtio-shm. If we had another transport, those drivers would be agnostic toward it. We really want to preserve the ability to use all devices over a PCI transport. That's a critical requirement for us.
The problem with vbus as it stands today, is that it presents vbus -> virtio-ring -> virtio-net and allows drivers to target either virtio-ring or vbus directly. If a driver targets vbus directly, then the driver is no longer transport agnostic and we could not support that driver over PCI.
