Hi, Lajos, We use OPNFV-9.0.0 to deploy Openstack, ODL and vswitch. ovsdb_connection in neutron.conf is set "tcp:127.0.0.1:6639" The vswitch created tapXXXXXXX for instance attach to it before but somehow create vhuXXXXXXX which fail to create the instance. Thank you.

Hi, Based on the screenshots ovsdb and libvirt seems to be unable to connect to ovsdb. I would check if configuration for ovsdb connection (like ovsdb_connection for neutron), and it is really possible to use those addresses to connect manually to ovsdb. Not sure if Openstack stein supported/tested together with neon ODL, I can't find the page where these are listed.

Dear Sir,

This our testbed: Openstack (stein) + Opendaylight (neon) + ovs (v2.11.1)

We have trouble when creating vnf on compute node using OpenStack CLI: #openstack vnf create vnfd1 vnf1

Here are the log message and ovs information. COMPUTE NODE1: nova-compute.log [image: error1.png] [image: list1.png] [image: vsctl1.png]

COMPUTE NODE 2: nova-compute.log [image: error2.png] [image: list2.png] [image: vsctl2.png]

We don't use DPDK on our Openvswitch. Can anyone give us some advice on this issue?

Thanks for helping us.
