Hi Liyong,

I think may be that is a consequent. At least it is not the reason for the 
following error, 


        2016-06-06 09:19:45.236 1 ERROR neutron.agent.ovsdb.impl_vsctl 
[req-5b368888-4eae-45d0-8240-ed9e76b04a73 - - - - -] Unable to execute 
['ovs-vsctl', '--timeout=10', '--oneline', '--format=json', '--', 
'--columns=type', 'list', 'Interface', 'int-br-ex']. Exception: Exit code: 
1; Stdin: ; Stdout: ; Stderr: ovs-vsctl: no row "int-br-ex" in table 
Interface 

because with those interfaces down, i can still execute 

        ovs-vsctl --timeout=10 --oneline --format=json -- --columns=type 
list Interface int-br-ex

 successfully manually.


Thank you,
Zhijiang

I noted that these devices are not in UP state, you’d better to check 
them first.

Subject: [openstack-dev] [Neutron][Kolla][ovs-discuss] error when starting 
neutron-openvswitch-agent service
 
Hi Guys, 

I am new to Neutron Kolla and OVS, I was trying to deploy Mitaka on 
CeontOS in a all-in-one environment using Kolla. After a successful 
deploying I realized that I should disable NetworkManager service roughly 
according to: 
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/3/html/Installation_and_Configuration_Guide/Disabling_Network_Manager.html 


But when I disabled NetworkManager and restarted network service (probably 
host machine also restarted), I cannot ping from my gateway through the 
external interface. 

Here is the relevant log of ovs:

I use enp0s35 as both the VIP interface and the external interface because 
the host only has one interface... 



Here is the ip addr  result before the deployment of enp0s35:

Please help to see how to locate solve such kind of problem, many thanks!
