I installed Redhat OpenStack Platform 7 with 1 controller and 1 compute nodes.

Now, I am configuring SRIOV by following the instructions in the below link:

I created neutron network, subnet and port.

I launched cirros instance and it failed to spawn.

I see this error in nova compute logs - NovaException: Unexpected vif_type=binding_failed

How to debug and fix this issue?

Are there any relevant logs in nova-scheduler or nova-conductor?

Yes, I see this error - unsupported configuration: host doesn't support passthrough of host PCI devices\

Have correctly you enabled SR-IOV? what is the output of lspci | grep -i virtual? It should show you the virtual functions created. Ensure you haven't missed any step from the documentation.

I think this error means nova wasn't able to get a port binding from neutron. You should collect the neutron-server logs from your controller and look for errors--/var/log/neutron/server.log is likely where you'll find it for OSP7.

That info is needed for anyone to help debug.

Thanks. I missed few configurations in neutron conf files. I fixed it and I am able to launch instance with VF attached to it.
