1 === VTN OpenStack Configuration
3 This guide describes how to set up OpenStack for integration with OpenDaylight Controller.
5 While OpenDaylight Controller provides several ways to integrate with OpenStack, this guide focus on the way which uses VTN features available on OpenDaylight. In the integration, VTN Manager work as network service provider for OpenStack.
7 VTN Manager features, enable OpenStack to work in pure OpenFlow environment in which all switches in data plane are OpenFlow switch.
10 To use OpenDaylight as Network Service Provider for OpenStack.
13 * OpenDaylight Controller.
14 * OpenStack Control Node.
15 * OpenStack Compute Node.
16 * OpenFlow Switch like mininet(Not Mandatory).
18 The VTN features support multiple OpenStack nodes. You can deploy multiple OpenStack Compute Nodes.
19 In management plane, OpenDaylight Controller, OpenStack nodes and OpenFlow switches should communicate with each other.
20 In data plane, Open vSwitches running in OpenStack nodes should communicate with each other through a physical or logical OpenFlow switches. The core OpenFlow switches are not mandatory. Therefore, you can directly connect to the Open vSwitch's.
23 image::vtn/vtn_devstack_setup.png["LAB Setup" ,width= 500]
24 NOTE: Ubuntu 14.04 was used in both the nodes and Vsphere was used for this howto.
30 - Install Ubuntu 14.04 LTS in two servers (OpenStack Control node and Compute node respectively)
31 - While installing, Ubuntu mandates creation of a User, we created the user "stack"(We will use the same user for running devstack)
32 NOTE: You can also have multiple Compute nodes.
33 TIP: Please do minimal Install to avoid any issues in devstack bringup
36 - Login to both servers
37 - Disable Ubuntu Firewall
42 - Optionally install these packages
45 sudo apt-get install net-tools
47 - Edit sudo vim /etc/sudoers and add an entry as follows
50 stack ALL=(ALL) NOPASSWD: ALL
53 - Checked the output of ifconfig -a, two interfaces were listed eth0 and eth1 as indicated in the image above.
54 - We had connected eth0 interface to the Network where OpenDaylight is reachable.
55 - eth1 interface in both servers were connected to a different network to act as data plane for the VM's created using the OpenStack.
56 - Manually edited the file : sudo vim /etc/network/interfaces and made entries as follows
59 stack@ubuntu-devstack:~/devstack$ cat /etc/network/interfaces
60 # This file describes the network interfaces available on your system
61 # and how to activate them. For more information, see interfaces(5).
62 # The loop-back network interface
64 iface lo inet loopback
65 # The primary network interface
67 iface eth0 inet static
68 address <IP_ADDRESS_TO_REACH_ODL>
70 broadcast <BROADCAST_IP_ADDRESS>
71 gateway <GATEWAY_IP_ADDRESS>
73 iface eth1 inet static
74 address <IP_ADDRESS_UNIQ>
77 NOTE: Please ensure that the eth0 interface is the default route and it is able to reach the ODL_IP_ADDRESS
78 NOTE: The entries for eth1 are not mandatory, If not set, we may have to manually do "ifup eth1" after the stacking is complete to activate the interface
81 - reboot both nodes after the user and network settings to have the network settings applied to the network
82 - Login again and check the output of ifconfig to ensure that both interfaces are listed
84 ==== OpenDaylight Settings and Execution
86 ===== VTN Configuration for OpenStack Integration:
88 * VTN uses the configuration parameters from "90-vtn-neutron.xml" file for the OpenStack integration.
89 * These values will be set for the OpenvSwitch, in all the participating OpenStack nodes.
90 * A configuration file "90-vtn-neutron.xml" will be generated automatically by following the below steps,
91 * Download the latest Beryllium karaf distribution from the below link,
94 http://www.opendaylight.org/software/downloads
97 * cd "distribution-karaf-0.4.0-Beryllium" and run karaf by using the following command "./bin/karaf".
98 * Install the below feature to generate "90-vtn-neutron.xml",
101 feature:install odl-vtn-manager-neutron
104 * Check "90-vtn-neutron.xml" file from the following path "distribution-karaf-0.4.0-Beryllium/etc/opendaylight/karaf/".
106 TIP: After running OpenDaylight, please ensure OpenDaylight listens to the ports:6633,6653, 6640 and 8080
108 TIP: Please allow the ports in firewall for the devstack to be able to communicate with OpenDaylight.
112 * 6633/6653 - OpenFlow Ports
113 * 6640 - Open vSwitch Manager Port
114 * 8282 - Port for REST API
116 * The contents of "90-vtn-neutron.xml" should be as follows:
124 * The values of the configuration parameters must be changed based on the user environment.
125 * Especially, "portname" should be carefully configured, because if the value is wrong, OpenDaylight fails to forward packets.
126 * Other parameters works fine as is for general use cases.
128 *** The name of the bridge in Open vSwitch, that will be created by OpenDaylight Controller.
129 *** It must be "br-int".
131 *** The name of the port that will be created in the vbridge in Open vSwitch.
132 *** This must be the same name of the interface of OpenStack Nodes which is used for interconnecting OpenStack Nodes in data plane.(in our case:eth1)
133 *** By default, if 90-vtn-neutron.xml is not created, VTN uses ens33 as portname.
135 *** OpenFlow protocol through which OpenFlow Switch and Controller communicate.
136 *** The values can be OpenFlow13 or OpenFlow10.
138 *** The value can be "standalone" or "secure".
139 *** Please use "secure" for general use cases.
143 ===== VTN Devstack Script
144 * The local.conf is a user-maintained settings file. This allows all custom settings for DevStack to be contained in a single file. This file is processed strictly in sequence.
145 The following data are needed to be set in the local.conf file:
146 * Set the Host_IP as the detection is unreliable.
147 * Set FLOATING_RANGE to a range not used on the local network, i.e. 192.168.1.224/27. This configures IP addresses ending in 225-254 to be used as floating IPs.
148 * Set FLAT_INTERFACE to the Ethernet interface that connects the host to your local network. This is the interface that should be configured with the static IP address mentioned above.
149 * If the *_PASSWORD variables are not set, we will be prompted to enter values during the execution of stack.sh.
150 * Set ADMIN_PASSWORD . This password is used for the admin and demo accounts set up as OpenStack users. We can login to the OpenStack GUI with this credentials only.
151 * Set the MYSQL_PASSWORD. The default here is a random hex string which is inconvenient if you need to look at the database directly for anything.
152 * Set the RABBIT_PASSWORD. This is used by messaging services used by both the nodes.
153 * Set the service password. This is used by the OpenStack services (Nova, Glance, etc) to authenticate with Keystone.

347 We have to comment OFFLINE=TRUE in local.conf files, this will make all the installations to happen automatically.
348 RECLONE=yes only when we set up the DevStack environment from scratch.
350 ===== Get Devstack (All nodes)
351 * Install git application using
352 ** sudo apt-get install git
354 ** git clone https://git.openstack.org/openstack-dev/devstack;
355 * Switch to stable/Juno Version branch
359 git checkout stable/juno
362 If you want to use stable/kilo Version branch, Please execute the below command in devstack folder
365 git checkout stable/kilo
368 If you want to use stable/liberty Version branch, Please execute the below command in devstack folder
371 git checkout stable/liberty
373 ===== Stack Control Node
375 .local.conf: <<_devstack_control,DevStack Control>>
377 cd devstack in the controller node
379 * Copy the contents of local.conf for juno (devstack control node) from <<_devstack_control,DevStack Control>> and save it as "local.conf" in the "devstack".
380 * Copy the contents of local.conf for kilo and liberty (devstack control node) from <<_devstack_kilo_liberty_control_node,Devstack Kilo_Liberty Control Node>> and save it as "local.conf" in the "devstack".
381 * Please modify the IP Address values as required.
386 ====== Verify Control Node stacking
387 * stack.sh prints out Horizon is now available at http://<CONTROL_NODE_IP_ADDRESS>:8080/
388 * Execute the command 'sudo ovs-vsctl show' in the control node terminal and verify if the bridge 'br-int' is created.
390 ===== Stack Compute Node
392 .local.conf: <<_devstack_compute,DevStack Compute>>
394 cd devstack in the controller node
396 * Copy the contents of local.conf for juno (devstack compute node) from <<_devstack_compute,DevStack Compute>> and save it as "local.conf" in the "devstack".
397 * Copy the contents of local.conf file for kilo and liberty (devstack compute node) from <<_devstack_kilo_liberty_compute_node,Devstack Kilo_Liberty Compute Node>> and save it as "local.conf" in the "devstack".
398 * Please modify the IP Address values as required.
404 ====== Verify Compute Node Stacking
405 * stack.sh prints out This is your host ip: <COMPUTE_NODE_IP_ADDRESS>
406 * Execute the command 'sudo ovs-vsctl show' in the control node terminal and verify if the bridge 'br-int' is created.
407 * The output of the ovs-vsctl show will be similar to the one seen in control node.
409 ===== Additional Verifications
410 * Please visit the OpenDaylight DLUX GUI after stacking all the nodes, http://<ODL_IP_ADDRESS>:8181/index.html. The switches, topology and the ports that are currently read can be validated.
412 TIP: If the interconnected between the Open vSwitch is not seen, Please bring up the interface for the dataplane manually using the below comamnd
415 ifup <interface_name>
417 TIP: Some versions of Open vSwitch, drop packets when there is a table-miss, So please add the below flow to all the nodes with Open vSwitch version (>=2.1)
420 ovs-ofctl --protocols=OpenFlow13 add-flow br-int priority=0,actions=output:CONTROLLER
422 TIP: Please Accept Promiscuous mode in the networks involving the interconnect.
424 ===== Create VM from Devstack Horizon GUI
425 * Login to http://<CONTROL_NODE_IP>:8080/ to check the horizon GUI.
428 image::vtn/OpenStackGui.png["Horizon",width= 600]
430 Enter the value for User Name as admin and enter the value for Password as labstack.
432 * We should first ensure both the hypervisors(control node and compute node) are mapped under hypervisors by clicking on Hpervisors tab.

493 ===== Verification of Control and Compute Node after VM creation
494 * Every time a new VM is created, more interfaces are added to the br-int bridge in Open vSwitch.
495 * Use *sudo ovs-vsctl show* to list the number of interfaces added.
496 * Please visit the DLUX GUI to list the new nodes in every switch.
498 ==== Using the DLUX GUI
