Open Stack

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:

2: enp0s25: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast 
state UP qlen 1000
    link/ether 1c:6f:65:05:37:11 brd ff:ff:ff:ff:ff:ff

    inet6 fe80::1e6f:65ff:fe05:3711/64 scope link

Here is the ip addr result after the deployment

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