Instructions for how to configure Openstack to use Brocade SDN Controller (or OpenDaylight)

See the video of the complete install on youtube: https://www.youtube.com/watch?v=tXw4W3RQDMM

1. Create Ravello account - https://www.ravellosystems.com/
2. Copy Openstack Kilo blueprint from repo - https://www.ravellosystems.com/repo/blueprints/60360952
3. Create application
4. Add key to application
5. Add bscui port to application - http port 9001
6. Add bscrest port to application - http port 8181
7. Add novnc port to application - https port 6080
8. Publish application - chooose AWS
9. Confirm openstack works by logging into the openstack UI - use dns name and port 443 i.e. https to login to openstack UI
10. Create openstack instance to confirm that openstack is working
11. Fix novnc console access using dns name by editing /etc/nova/nova.conf on each compute node and restart nova-compute: systemctl restart openstack-nova-compute
12. Delete openstack instance
13. Install BSC on control node. Find detailed installation video here: https://www.youtube.com/watch?v=5jxEhQXa2NM (if the installation fails this video might provide a helpful workaround: https://www.youtube.com/watch?v=n1PnXcjJHJ4)
14. Confirm UI access to BSC on control node on port 9001 but will be unable to login
15. Fix login issue by patching BSC - get patch using

curl https://raw.githubusercontent.com/Elbrys/bsc_openstack/master/bvc2.patch > bvc2.patch 
sudo yum install -y patch
pushd / && patch -p0 < ~/bvc2.patch && popd

16. Confirm login to BSC now works

17. Clean openstack state

    . keystonerc_admin
    nova list
    nova delete <instance-name>
    neutron router-list
    neutron router-port-list <router>
    neutron router-interface-delete <router> <subnet>
    neutron floatingip-list
    neutron floatingip-delete
    neutron port-list
    neutron port-delete <port>
    neutron router-delete <router>
    neutron subnet-list
    neutron subnet-delete <subnet>
    neutron net-list
    neutron net-delete <network>
    

18. On control node turn off neutron server

    systemctl stop neutron-server
    

19. Create script set_ovs.sh, set it to executable and copy it to neutron and compute nodes

    curl https://raw.githubusercontent.com/Elbrys/bsc_openstack/master/set_ovs.sh > set_ovs.sh
    chmod a+x set_ovs.sh
    scp set_ovs.sh neutron:~/
    scp set_ovs.sh compute1:~/
    scp set_ovs.sh compute2:~/
    

20. On each node (neutron, compute1, compute2) turn off and disable neutron-openvswitch-agent

    systemctl stop neutron-openvswitch-agent
    systemctl disable neutron-openvswitch-agent
    

21. Clean openvswitch config and configure openvswitch to connect to BSC controller (neutron, compute1, and compute2 only)

    systemctl stop openvswitch
    rm -rf /var/log/openvswitch/*
    rm -rf /etc/openvswitch/conf.db
    systemctl start openvswitch
    

22. Confirm clean openvswitch state

    ovs-vsctl show
    

23. Configure manager on openvswitch using the set_ovs.sh script

    ./set_ovs.sh
    

24. Do ovs-vsctl show and notice that ovs is not connected. Need to clear selinux permissions to allow connections. On all 4 nodes:

    setenforce 0
    sed -i -e 's/SELINUX=enforcing/SELINUX=permissive/g' /etc/selinux/config
    

25. Check ovs-vsctl and look for connected status - if still not connected then reboot as recommended in next step

26. Reboot compute and neutron nodes.

27. Check BSC UI topology manager to make sure that all 3 switches are showing up there. If BSC UI topology manager isn't working ODL topology can be checked here:

<ip or dns of controller>:8181/restconf/operational/network-topology:network-topology/

28. Configure control node to use BSC (note neutron-server is currently stopped)

    crudini --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 mechanism_drivers opendaylight 
    crudini --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 tenant_network_types vxlan
    
    cat <<EOT>> /etc/neutron/plugins/ml2/ml2_conf.ini 
    [ml2_odl]
    password = admin
    username = admin
    url = http://192.168.0.10:8181/controller/nb/v2/neutron
    EOT
    
    mysql -e "drop database if exists neutron_ml2;"
    mysql -e "create database neutron_ml2 character set utf8;"
    mysql -e "grant all on neutron_ml2.* to 'neutron'@'%';"
    neutron-db-manage --config-file /usr/share/neutron/neutron-dist.conf --config-file /etc/neutron/neutron.conf \
    --config-file /etc/neutron/plugin.ini upgrade head
    

29. Start neutron-server

    systemctl start neutron-server
    

    Note that server fails to start

30. Check /var/log/neutron/server.log for issue

31. edit /etc/neutron/plugins/ml2/ml2_conf.ini to add vxlan to available network types

    vi /etc/neutron/plugins/ml2/ml2_conf.ini
    

32. Start neutron-server

    systemctl start neutron-server
    

    Note that server fails to start

33. Check /var/log/neutron/server.log for issue

34. Install networking-odl to fix issue with driver

    yum install -y python-pip
    pip install networking-odl
    

35. Start neutron-server - this time it should start

    systemctl start neutron-server 
    

36. Create instances in openstack UI and verify you can ping between instances

37. You can check ODL neutron ml2 config here:

    http://:8181/controller/nb/v2/neutron/networks

38. Check output of ovs-vsctl on compute and neutron nodes to see correct config. It should look similar to this (note the vxlan tunnels under the br-int port):

[root@compute1 ~]# ovs-vsctl show
