Open Stack

Hi, all

I build a devstack which code from master branch. By default the OVS
version is 2.0.2 when install devstack. So I reinstall the OVS 2.6.0.

I meet an exception in OVS agent when all OVS services runs okay. Exception
shows below:

2016-11-17 15:47:29.175 ERROR neutron.agent.linux.utils

I want to know why OVS agent tells me these info. All the OVS services run
okay. I use " ovs-vsctl show " to ensure OVS services and the output is
right.

The detailed output when excute " ovs-vsctl show ":

root at devstack:~/openvswitch-2.6.0# ovs-vsctl show
6e695086-6663-4fd0-b713-5a12605c92cb
    Manager "ptcp:6640:127.0.0.1"
        is_connected: true
    Bridge br-ex
        Controller "tcp:127.0.0.1:6633"
            is_connected: true
        fail_mode: secure
        Port br-ex
            Interface br-ex
                type: internal
        Port phy-br-ex
            Interface phy-br-ex
                type: patch
                options: {peer=int-br-ex}
... ...

I think that OVS runs okay.

Did I miss some configuration or something about neutron or OVS?


Hope for your reply. :-)
