Dear Volodymyr, all,
thanks for your fast answer ...
but I'm still facing the same problem, still can't ping the instance
with configured and up OVS bridge ... may because I'm quite new to
OpenStack and OpenVswitch and didn't see the problem ;)
My setup is devstack Mitaka in single machine config ... first of all I
didn't find there the openvswitch_agent.ini anymore, I remember in
previous version it was in the neutron/plugin folder ...
Is this config now done in the ml2 config file in the [OVS] section????
I'm really wondering ...
so I can ping between the 2 instances without any problem. But as soon I
bring up the OVS bridge inside the vm the ARP requests only visible at
the ens interface but not reaching the OVSbr ...
please find attached two files which may help for troubleshooting. One
are some network information from inside the Instance that runs the OVS
and one ovs-vsctl info of the OpenStack Host.
If you need more info/logs please let me know! Thanks for your help!
BR Mathias.

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 ...

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.
