[dpdk-users] dpdk on Centos7

Hello,

I'm using DPDK-stable-16.11.2 release on a CentOS7 VM running on my
laptop (Windows7). CentOS is started using VMPlayer.

I have created two network interfaces under CentOS7 to try out DPDK
using Player->Manage->Virtual-Settings->Network-Adapter-> "Host
only"...

Now, under Centos I see both these interfaces are using e1000 driver
(checked using ethtool). Starting the forwarding app, I get the
following error:
==============================================================
... --no-huge -- --MAC-PORT 00:0c:29:23:be:d6 --MAC-PORT 00:0c:29:23:be:d6
EAL: Detected 4 lcore(s)
EAL: Probing VFIO support...
EAL: PCI device 0000:02:01.0 on NUMA socket -1

EAL: PCI device 0000:02:06.0 on NUMA socket -1
EAL:   probe driver: 8086:100f net_e1000_em
nb_ports = 0
================================================


Is there a particular I need to enable to let DPDK detect these interfaces?

I tried "ixgbe" and "igb_uio" but got the following error:
[root at localhost tools]# ./dpdk-devbind.py -b ixgbe 02:05.0
Warning - no supported modules(DPDK driver) are loaded
Routing table indicates that interface 0000:02:05.0 is active. Not modifying


Any ideas? I'm new to this.

Thanks a lot!
