[rdo-users] [Tripleo] Composable role OVS-DPDK compute node with single NIC

[Samuel Monderer]

Hi,

I managed to deploy a compute node with ovs-dpdk using two NICs. The first
for the provisioning network and control plane, the other NIC is used
tenant network over ovs-dpdk.

I then tried 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
