Guys,

I am also trying this:

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

---
pci     0000:01:00.0    vfio-pci
pci     0000:01:00.1    vfio-pci
---

According to: https://github.com/openvswitch/ovs/blob/master/INSTALL.DPDK.md
- but, it also doesn't work...

When using "vfio-pci", the NIC doesn't even show up as a DPDK-compatible
driver after running: "dpdk_nic_bind --status"...

So, how to use "vfio-pci" with Ubuntu DPDK?

Cheers!
Thiago
