Have you looked at the virtio specification? This describes
the overall structure and communication mechanism, which
QEMU and Linux each only implement one half of:
http://docs.oasis-open.org/virtio/virtio/v1.0/virtio-v1.0.html

Hopefully it will provide the higher level overview
that you are looking for. Many of the data structures
and their purposes are also directly required and
described by the spec.
