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

Samuel,

Can you attach an unmodified version of this NIC config, rather than copy/paste into the email?

I think you have an issue here:

members:
-
type: ovs_dpdk_port
name: dpdk0
members:
-
type: interface
name: nic1

It appears that you have the ovs_dpdk_port as a member of the user bridge, but then you have the NIC and the VLANs as members of the ovs_dpdk_port, but the VLANs should be members of the bridge, not the ovs_dpdk_port.

But that might not be the case, which is why I would like to see the original unmodifed NIC config.
