Newton - "ERROR oslo_service.service NovaException: Unsupported VIF type binding_failed convert '_nova_to_osvif_vif_binding_failed'"

Latest response

We are using RedHAT OSP Newton release and 2 compute nodes and using OVS-DPDK for networking. On one of the compute nodes, we see the following errors inside compute.log and this error prevents launching new instances on that compute node:

We have tried deleting and creating br-int and rebooting the compute node but it didn't help.
Do you have an idea on this?
