Xenial - OpenvSwitch with DPDK binding to 10G NIC, not working...

[Martinx - ジェームズ]

Hey guys,

 I'm trying to create two OVS bridges powered by DPDK, on Xenial, but I'm
facing problems...

 First, there is no documentation about how to do this... So far, I found
the following:


 - This link doesn't how to bind real NIC:

https://software.intel.com/en-us/articles/using-open-vswitch-with-dpdk-on-ubuntu

 - This one isn't specific to Ubuntu OVS + DPDK packages:
 https://github.com/openvswitch/ovs/blob/master/INSTALL.DPDK.md

 - Similar with above but, very old... Also not related to Ubuntu packages:
 https://feiskyer.github.io/2015/03/01/open-vswitch-over-dpdk-on-ubuntu/


 So, to begin with, I start with Intel.com guide, it worked! But without
real NIC.

 Then, I tried to bind it to real NIC, like this:

 Added two NIC PCI id to "/etc/dpdk/interfaces" file:

---
pci     0000:01:00.0    uio-pci-generic
pci     0000:01:00.1    uio-pci-generic
---

 Then, reboot, I can see both NICs using "DPDK-compatible driver" by
running: "dpdk_nic_bind --status".

 Trying to create new OVS Bridges with DPDK devices, failing:

---
root at xenial-1:~# ovs-vsctl add-br ovsbr0
root at xenial-1:~# ovs-vsctl set bridge ovsbr0 datapath_type=netdev
root at xenial-1:~# ovs-vsctl add-port ovsbr0 dpdk0 -- set Interface dpdk0
type=dpdk
ovs-vsctl: Error detected while setting up 'dpdk0'.  See ovs-vswitchd log
for details.
---

Log shows:

---
2016-03-07T19:34:07.532Z|00136|bridge|WARN|could not open network device
dpdk0 (No such device)
---

---
root at xenial-1:~# ovs-vsctl show
2b84f2f7-6d3f-4d51-94a5-fe6d04f0a062
    Bridge "ovsbr0"
        Port "ovsbr0"
            Interface "ovsbr0"
                type: internal
        Port "dpdk0"
            Interface "dpdk0"
                type: dpdk
                error: "could not open network device dpdk0 (No such
device)"
    ovs_version: "2.5.0"
---

 What am I missing?

 I tried to use real NIC device name "em1", instead of "dpdk0", same
results... Since "em1" does not even shows up on "ip link" list... DPDK
toke it over...

Thanks!
Thiago
