Hi Daniele,
Thanks for your reply :)
I'm using openvswitch-2.3.1 and compiled using below set of commands.
export DPDK_DIR=/root/dpdk-1.7.1
cd /root/dpdk-1.7.1
make install T=x86_64-native-linuxapp-gcc
cd /root/openvswitch-2.3.1
export DPDK_BUILD=$DPDK_DIR/x86_64-native-linuxapp-gcc/
./boot.sh
./configure --with-dpdk=$DPDK_BUILD
make
I would like to create a OVS bridge by adding ens3f0 & ens3f1 ports to that.
[root at artha ~]# /root/dpdk-1.7.1/tools/dpdk_nic_bind.py --status
Network devices using DPDK-compatible driver
============================================
<none>
Network devices using kernel driver
===================================
0000:0a:00.0 'I350 Gigabit Network Connection' if=ens3f0 drv=igb unused=
0000:0a:00.1 'I350 Gigabit Network Connection' if=ens3f1 drv=igb unused=
[root at artha ~]# ifconfig -a|grep flags
ens3f0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
ens3f1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
PFA setup.sh script, for all the cmd which I used to run ovs.
1. I added "default_hugepagesz=1GB hugepagesz=1G hugepages=1" to the boot line and 1 GB huge page created
2. When I bind igb_uio driver [to 0000:0a:00.0 & 0000:0a:00.1 ] and then if I run vswitch daemon [--with dpdk], Ideally it should detect binded PCI device. Am I right?
Please let me know if I'm missing something or something is incorrect
Thanks & Regards,
Varun

The commands you're typing seem correct.
Which version of OVS are you using? How are you compiling it?
