I agree. We need a Lego set containing the following bricks:
- bus interfaces: pci bus, hypercall-based bus, xenbus
- functionality: net driver, block driver
- virtio data path: xen rings + grant tables + event channels, kvm rings
+ kmap_atomic + interrupts
So you can write a 4-line driver that glues the pci bus interface to the
net functionality driver to kvm virtio backend, and take the rest of the
day off.
