This document outlines an agenda for a DevNet workshop on using OpenStack with OpenDaylight. The agenda includes installing OpenStack, installing OpenDaylight, configuring OpenStack to use OpenDaylight, verifying the system works, troubleshooting, and a Q&A session. OpenDaylight is an open source SDN controller that can provide advanced networking capabilities for OpenStack deployments by managing network endpoints and traffic through plugins like Neutron/ML2. Both projects are complex to install but integrating them can enable significant benefits for advanced networking in OpenStack clouds.

Editor's Notes
- #7: Collection of services that focus on different aspects of a cloud Dashboard (Horizon) – provides portal for uses to view and interact with their cloud Core Services for Compute (Nova), Storage (Cinder), and Network (Neutron) Infrastructure plugins to allow core services to talk to underlying physical/virtual infrastructure – similar to drivers in an operating system Common set of APIs across all service
- #10: Large open source project Focus is Software-Defined Networking (SDN) Modular, model driven controller at core Northbound APIs to apps, e.g. to OpenStack neutron Southbound interfaces to network devices, e.g. OVSDB to OpenvSwitches
- #11: Software Defined Networking (SDN) Controller Platform for network aware apps Northbound APIs to apps (e.g. OpenStack) Southbound APIs to network devices (e.g. OpenVSwitch)
- #15: When using OpenDaylight as the Neutron back-end, ODL expects to be the only source of truth for Open vSwitch configuration. Because of this, it is necessary to remove existing OpenStack and Open vSwitch configurations to give OpenDaylight a clean slate. Configure Neutron to use OpenDaylight’s ML2 driver
