RDO Setup Two Real Node (Controller+Compute) IceHouse Neutron ML2&OVS&VXLAN Cluster on CentOS 7

As of 07/28/2014 Bug https://ask.openstack.org/en/question/35705/attempt-of-rdo-aio-install-icehouse-on-centos-7/ is still pending and workaround suggested above should be applied during two node RDO packstack installation.
Successful implementation of Neutron ML2&&OVS&&VXLAN multi node setup requires correct version of plugin.ini -> /etc/neutron/plugins/ml2/ml2_conf.ini which appears to be generated with errors by packstack.

Two boxes  have been setup , each one having 2  NICs (enp2s0,enp5s1) for
Controller && Compute Nodes setup. Before running
`packstack –answer-file=TwoNodeVXLAN.txt` SELINUX set to permissive on both nodes.Both enp5s1’s assigned IPs and set to promiscuous mode (192.168.0.127, 192.168.0.137 ). Services firewalld and NetworkManager disabled, IPv4 firewall with iptables and service network are enabled and running. Packstack is bind to public IP of interface enp2s0 192.169.1.127, Compute Node is 192.169.1.137 ( view answer-file ).

Setup configuration

– Controller node: Nova, Keystone, Cinder, Glance, Neutron (using Open vSwitch plugin && VXLAN )
– Compute node: Nova (nova-compute), Neutron (openvswitch-agent)

icehouse1.localdomain   –  Controller (192.168.1.127)
icehouse2.localdomain   –  Compute   (192.168.1.137)

7 Responses to RDO Setup Two Real Node (Controller+Compute) IceHouse Neutron ML2&OVS&VXLAN Cluster on CentOS 7

  1. Ehwan Kho says:

    My configs got error when running the packstack related to br-eth1 can you please show us your ifcfg-br-* and ifcfg-eth? configurations if okay with you. Did you define it at first before running packstack? Thanks.

  2. Edward says:

    Thanks very much for sharing.

    you said:

    Packstack is bind to public IP of interface enp2s0 192.169.1.127, Compute Node is 192.169.1.137 ( view answer-file ):

    Should they be 192.168.1.127 and 192.168.1.137?

      • Edward says:

        Thanks for answering.

        May I consult you on RDO + Neutron + ML2 + OVS + VXLAN
        on CentOS 6.5 (updated kernel 3.10.42-1.el6.x86_64)?

        1. Does RDO + Neutron + ML2 + OVS + VXLAN work on CebtOS 6.5?

        2. if yes, on neutron server, I saw the following three ports for br-tun through ovs-vsctl show as:
        ———-
        Bridge br-tun
        Port “vxlan-c0a80168”
        Interface “vxlan-c0a80168″
        type: vxlan
        options: {in_key=flow, local_ip=”192.168.1.105″, out_key=flow, remote_ip=”192.168.1.104”}
        Port patch-int
        Interface patch-int
        type: patch
        options: {peer=patch-tun}
        Port br-tun
        Interface br-tun
        type: internal
        ———-

        However, through ovs-ofctl show br-tun, I saw only two interfaces as:
        ———–
        OFPT_FEATURES_REPLY (xid=0x2): dpid:00007e1d5c3f2b4b
        n_tables:254, n_buffers:256

        OFPT_GET_CONFIG_REPLY (xid=0x4): frags=normal miss_send_len=0
        ———

        3. UDP port for vxlan is 4789 or 8472?

        Thanks.

  3. dbaxps says:

    Please, post question on ask.openstack.org. You would get response
    from more people.UDP port for vxlan is 4789

  4. dbaxps says:

    I don’t have experience with 6.5
