Yes, the openvswitch daemon goes directly to the ovs_neutron_plugin.ini

Ok, now I'm getting somewhere. Seems that I was mistaken in what used what.
So the ml2 ini file is/should not used by the openvswitch agent but only by the server part?

Yep!
It now makes some sense why stuff was not working :)
I thought the ml2 plug also affected the openvswitch daemon but apparently that does not use this config at all?
Somewhat weird as I understood this makes the agent more pluggable but it only affects the server part?
