Open Stack

I've finally finished my writeup describing the experiments that we
performed using Openstack to drive a wide area 100 gigabit network.
I've included all of the details for configuration and tuning, as well
as speculation why we're seeing such good numbers.

tl;dr: you can push a whole lot of network bandwidth out of an
openstack deployment with kvm/virtio; we hit 98 gigabits peak with 10
instances across 50 ms of latency.

I'm happy to discuss this in more detail, if there are additional questions.
