I managed to load it on latest devstack (Mitaka). But when try the same thing on Kilo, whenever I instantiate a VM, I keep getting stuck on the error: NovaException: Unexpected vif_type=binding_failed. I've tried all answers online, and wasn't able to make this work.

This is the error on the controller:

This is the error on the compute:

My setup is:

2 compute nodes, Ubunto 14.04, devstack Kilo, networking-ovs-dpdk Kilo.
private network is vxlan.
