The dreaded layer2 data center link conversation may never …
Installing Open vSwitch with KVM
This tutorial is for installing Open vSwitch with KVM in order to replace traditional hypervisor Ethernet switching using Linux bridging with Open vSwitch. I rebuilt this box becuase as fun as it was to setup OpenStack (I think) there are a million modules that would take more time to clip out rather than just rebuilding. Anyone gotten Nova integrated into …
OpenStack on Ubuntu 11.10 Installation
My notes from an OpenStack & Ubuntu 11.10. These are only my notes. Lots of errors. It was a fairly painless install. I didnt have the lab gear setup with two Nics so I got a bit kludgy at the end.

Top 10 Reasons I think SDN Openflow will gain momentum
Predicting the future is often as easy as looking at the past, no crystal ball required.
The MPLS and transport roles merge
