neutron-openvswitch-agent service</font>
<br><font size=3 face="Times New Roman"> </font>
<br><font size=2 face="Arial">Hi Guys,</font><font size=3 face="Times New Roman">
<br>
</font><font size=2 face="Arial"><br>
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 color=blue face="Arial"><u>https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/3/html/Installation_and_Configuration_Guide/Disabling_Network_Manager.html</u></font></a><font size=3 face="Times New Roman">
<br>
</font><font size=2 face="Arial"><br>
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><font size=3 face="Times New Roman"> <br>
