Am when you say dpdk interface do you mean dpdk physical interface is not reciving any packets or a vhost-user interface.

Can you provide the output of ovs-vsctl show.
And sudo /opt/stack/DPDK-v2.1.0/tools/dpdk_nic_bind.py –status

You should see an output similar to this.

Hi,

One thing i observed is there is no packets coming to the dpdk interface (data network).
I have verified it with the tcpdump using mirror interface.
and if i assign ip address and ping each other the data network bridges that is also not working.
could this be a possible cause for the nova exception? (NovaException: Unexpected vif_type=binding_failed)

Thanks
Praveen

Hi Sean,

Thanks for the reply.

Please find the logs attached.
ovs-dpdk is correctly running in compute.

Thanks
Praveen

Hi would you be able to attach the
n-cpu log form the computenode  and  the
n-sch and q-svc logs for the controller so we can see if there is a stack trace relating to the
vm boot.

Also can you confirm ovs-dpdk is running correctly on the compute node by running
sudo service ovs-dpdk status

the neutron and networking-ovs-dpdk commits are from their respective stable/kilo branches so they should be compatible
provided no breaking changes have been merged to either branch.

regards
sean.

Hi Przemek,

Thanks For the response,

Here are the commit ids for Neutron and networking-ovs-dpdk

[stack at localhost neutron]$ git log --format="%H" -n 1
026bfc6421da796075f71a9ad4378674f619193d
[stack at localhost neutron]$ cd ..
[stack at localhost ~]$ cd networking-ovs-dpdk/
[stack at localhost networking-ovs-dpdk]$  git log --format="%H" -n 1
90dd03a76a7e30cf76ecc657f23be8371b1181d2

The Neutron agents are up and running in compute node.

Thanks
Praveen

Hi Praveen,

There’s been some changes recently to networking-ovs-dpdk, it no longer host’s a mech driver as the openviswitch mech driver in Neutron supports vhost-user ports.
I guess something went wrong and the version of Neutron is not matching networking-ovs-dpdk. Can you post commit ids of Neutron and networking-ovs-dpdk.

The other possibility is that the Neutron agent is not running/died on the compute node.
Check with:
neutron agent-list

Subject: [openstack-dev] [networking-ovs-dpdk] VM creation fails with Unexpected vif_type=binding_failed

Hi,

Am trying to set up an open stack (kilo) installation using ovs-dpdk through devstack installation.

I have followed the " https://github.com/openstack/networking-ovs-dpdk/blob/master/doc/source/getstarted.rst " documentation.

I used the same versions as in documentation (fedora21, with right kernel).

My openstack installation is successful in both controller and compute.
I have used example local.conf given in the documentation.
But if i try to spawn the VM. I am having the following error.

"NovaException: Unexpected vif_type=binding_failed"

It would be really helpful if you can point out how to debug and fix this error.

Thanks
Praveen
