ovs gre tunnel problem. Dosent show up after ovs agent restart.
Hi,
Im starting to get blind on my config.
After I started with neutron and ovs the "neutron agent-list" are down, and my physical host.
My environment is one vm with keystone db, rabbit, and nova and neutron db.
One vm which is a network node with three vmx network interfaces.
One physical host which is the compute node with two network interfaces.
All is ubuntu 1404 (updated) with juno.
Below you can see ml2 config, and logs.
I have also checked this: http://bderzhavets.blogspot.com/2014/...
And mysql db tabels have correct ip addresses for the gre tunnel.
The problem started after i started with OVS. The Gre - tunnel seems working from the beginning but after restarting the neutron-plugin-openvswitch-agent the gre tunnel do not showing up in the "ovs-vsctl show" -list. The neutron-plugin-openvswitch-agent service will not start on the network node, it still running on compute node.
I have following the doc for juno and ubuntu 1404.
