May be that you need to check neutron server.log for more info on Port-Binding failure issues.

Can you look into bridge-mappings in the neutron configuration? And verify that ovs bridges are existing in the setup as per neutron configuration.

Hope this helps.

Subject: [Openstack] [openstack-dev] [networking-odl] [SRIOV] [OVS HW offload] ERROR in port binding

Hi,

We have a SRIOV NIC that supports SRIOV and OVS HW offload. We built a pike cluster with networking-odl as the mechanism driver.

As Sean mentioned that ODL part for SRIOV + OVS HW offload is not ready, so we applied the following patches to ODL(version Nitrogen) :

1. https://git.opendaylight.org/gerrit/#/c/62481/
2. https://git.opendaylight.org/gerrit/#/c/60259/

Now, when we create a direct vnic_type port and try to launch instances, we are running into issues.

1. The ODL patches didn't work straight away with Nitrogen version.
The patches needs to be rebased.

2. Modified Nova to include the pci device list. Also, added host-config to the compute node using the following command

ovs-vsctl set Open_vSwitch 7ef8db05-8a4f-4cea-8b3b-432416c102fc
external_ids:odl_os_hostconfig_config_odl_l2="{"supported_vnic_types":
[{"vnic_type": "normal", "vif_type":"ovs", "vif_details": {} },
{"vnic_type": "direct", "vif_type": "ovs", "vif_details": {} } ],
"allowed_network_types": ["local", "gre", "vlan", "vxlan"]}"

The error I am getting is from networking-odl ML2 driver. Do we need to apply any patch there too?

This is what the errror log says:

networking_odl.ml2.pseudo_agentdb_binding

Are we missing any additional configuration step?

TIA,
Pranab
