Why the NOS will decouple
Over the next couple of years some of us expect the networking industry to have some fairly significant changes. There are really two options: A distributed approach we have today or a controller based centralized model. We have today just that, autonomous devices building adjacencies to one another, exchanging what it hopes are the best healthy paths… Continue reading Why the NOS will decouple
February 2012 SDN Thoughts

My initial business cases still have not changed much from 4 months ago. It has always been and will be about money. What will drive this is the ability to… Continue reading February 2012 SDN Thoughts
OpenVswitch and GRE tunnel notes
Here is a quick post for setting up GRE tunnels on OpenVswitch. Both Vswitch boxes are attached to an OpenFlow Beacon controller. More up to date how-to can be found here: Configuring VXLan and GRE tunnels on OpenvSwitch KVM live storage migration makes an interesting story and run at VMware tools. The dreaded layer2 data… Continue reading OpenVswitch and GRE tunnel notes
[titled_box title=”Update:” variation=”slategrey”] My latest installation document for Folsom can be found at the post OpenStack Folsom Quantum Devstack Installation Tutorial and Screencast. It’s too tough to try and keep up with debugging installers myself so I am just using DevStack in that tutorial. Thanks![/titled_box]
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. I think the interesting component will be to replace the Openstack bridging with OpenVswitch.

Installing the OpenStack Dashboard
Here are the overall steps for creating the OpenStack dashboard.
Install the OpenStack Dashboard framework including Apache and related modules.
Configure the Dashboard.
Restart and run the Apache server.
Install the OpenStack Dashboard.
sudo apt-get install openstack-dashboard openstackx python-sqlite
Enable the rewrite module for apache: sudo a2enmod rewrite
sudo a2enmod rewrite
Next, create a symbolic link to “dash” with the Apache2 Enable site utility (a2ensite).
sudo a2ensite dash
Disable the “default” site so that the Dashboard can come up as the Apache site’s default.
sudo a2dissite default
