Thanks Sugesh.

Is VFIO required only when we have a virtualized infrastructure?
[Sugesh] Do you mean running OVS-DPDK inside VM/Connecting VMs to the OVS-DPDK?In either case,  you need only uio driver.


Thanks

Hello,

If one is setting up a OVS Switch with DPDK on a Intel Server with Intel NICs on Ubuntu 16.10, they could just use the UIO drivers right?  Do they don't need VFIO configuration [1] correct?  Assume that they Intel Server here is mainly acting as a hardware soft-switch is not running any virtualization.

Am I correct in my understanding?

[1] http://docs.openvswitch.org/en/latest/intro/install/dpdk/
[Sugesh] Yes, You can use the only UIO drivers to make it work


Thanks
