Hi Mathias,
whether you have all corresponding bridges and patches between them as
described in openvswitch_agent.ini using
integration_bridge
tunnel_bridge
int_peer_patch_port
tun_peer_patch_port
bridge_mappings
parameters? And make sure, that service "neutron-ovs-cleanup" is in use
during system boot. You can check these bridges and patches using
"ovs-vsctl show" command.

Dear all,
I'm quite new to openstack and like to install openVSwtich inside one
Instance of our Mitika openstack Lab Enviornment ...
But it seems that ARP packets got lost between the network interface
of the instance and the OVS bridge ...
With tcpdump on the interface I see the APR packets ...

but on the OVS bridge nothing arrives ...

I disabled port_security and removed the security group but nothing
changed

maybe the port_filter causes still the problem? But how to disable it?
Any other idea?
Thanks and BR Mathias.
