OVS Dpdk on computes with only one NIC

Hi,

I'm trying to deploy an overcloud with computes that ovs-dpdk.
I would like to use only a single nic for provisioning and ovs-dpdk.
I used the nic configuration below for the compute nodes running ovs-dpdk but encountered two problems.
First the tenant network was working (wasn't able to get DHCP running and even when I manually configured it wasn't able to reach the router)
Second the default route on control plane is not set even though it is configured in /etc/sysconfig/network-scripts/route-br-ex
