<font size=2 face="sans-serif">Hi Guys,</font>
<br>
<br><font size=2 face="sans-serif">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: </font><a href="https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/3/html/Installation_and_Configuration_Guide/Disabling_Network_Manager.html"><font size=2 face="sans-serif">https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/3/html/Installation_and_Configuration_Guide/Disabling_Network_Manager.html</font></a>
<br>
<br><font size=2 face="sans-serif">But when I disabled NetworkManager and
restarted network service (probably host machine also restarted), I cannot
ping from my gateway through the external interface.</font>
