Hi all, 

Question is. Why I have to restart neutron-plugin-openvswitch-agent to 
recover networking from new machines?


I found a problem creating machines in a new node I've built. And 
realized that this happens on all my nodes of current version. 

neutron 2.3.4
nova      2.17.0

My logs shows that neutron assign vlan 2 for the new machine and this 
causes the machine to not have connectivity. 

---------------------------------------
2014-12-14 17:57:07.321 12501 INFO 
neutron.plugins.openvswitch.agent.ovs_neutron_agent [-] Assigning 2 as 
local vlan for net-id=727b0415-f066-40d9-8147-183e07dd7b23
20
---------------------------------------


If I shut down the machine and restart neutron plugin agent for ovs:

#> restart neutron-plugin-openvswitch-agent


---------------------------------------
 ...  assigning 1 as local vlan for 
net-id=727b0415-f066-40d9-8147-183e07dd7b23

---------------------------------------


And the machine recovers connectivity. 

In the even of faillure (after creating it):

If I start the machine without ip and set it manually I can try to ping 
it. It says it's not reachable but after restating the plugin 
automatically recovers connectivity. So no restart or further 
configuration is made. 


Maybe I have something wrong configured but it seems like a bug.


Can someone point me to the right place?
