This is not a recommended way of using DPDK.

I am assuming that your dpdk ports are active (verified by ovs-vsctl
show command). The only usecases that we have validated is using DPDK
as provider network and DPDK as Tenant network [1] which will have the
tenant and vlan configured directly on the bridge (this configuration
was recommended from the ovs team).

I am not sure if there is any difference between system and netdev
bridges in setting the routes, but you could validate by adding logs
to the ifup scripts and trace it out why the route is not invoked.

Thanks.  Unfortunately I don't see anything obviously wrong with that, 
but I'm not a DPDK expert either.  Hopefully one of our networking gurus 
can chime in and comment on whether this should work.

Your configuration lost all of its indentation, which makes it extremely 
difficult to read.  Can you try sending it a different way, maybe

[openstack-dev] [Tripleo] Composable role OVS-DPDK compute node with single NIC

2017-11-16 Thread 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
