Hi,

I'm trying to deploy DPDK and ovs on an AWS EC2 instance which is running
CentOS 7.

Has anybody had tried to do this? How to bind a NIC to dpdk while it shows
no NICs when I do lspci?

Thanks!

Be sure to get an instance with SR-IOV, which is "enhanced networking" in
Amazon speak.

Just curious - I didn't understand the usage model here. In the Amazon EC2 instance (a VM,) do you want to run a DPDK application? Where do you intend to run OVS? 

As far I remember, OVS has a datapath in Host kernel and you won't be given Host access by AWS. And I'm not sure if Amazon provides an OVS instance, but in case if they don't have an offering, you have to put your OVS installation in another VM (virtualizing network function) and bounce the traffic back to your VM(s.)

As far as Amazon Advanced Networking is concerned, you get a dedicated slice (an SRIOV Virtual Function) of a NIC in your VM, where a Physical Function Driver running in the Host (Amazon VMM-Xen I think) controls all the filtering configuration privileges.

Thanks,
Rashmin

Thanks Andre and Rashmin!

I'm trying to deploy this dpdk-ovs on EC2.

https://github.com/01org/dpdk-ovs

But the way it works on my own machine seems quite different with it does
on the cloud. I'm still confused about the hardware virtualization on EC2.
