Hi All,
I am running the OpenvSwitch 2.4 version with DPDK 2.0 on Ubuntu 14.04
Virtual machine. I could successfully build both Open vswitch 2.4 &
DPDK 2.0, I am unable to figure out how to add the dpdk interface to the
bridge.
Here are the steps I have followed.
1.wget http://openvswitch.org/releases/openvswitch-2.4.0.tar.gz
2.tar -zxvf openvswitch-2.4.0.tar.gz
3.wget http://dpdk.org/browse/dpdk/snapshot/dpdk-2.0.0.tar.gz
4.tar -zxvf dpdk-2.0.0.tar.gz
5.export DPDK_DIR=/root/dpdk-2.0.0/
6.cd $DPDK_DIR
7.Update config/common_linuxapp with ‘CONFIG_RTE_LIBRTE_VHOST=y’
8.make install T=x86_64-native-linuxapp-gcc
9.export DPDK_BUILD=$DPDK_DIR/x86_64-native-linuxapp-gcc/
10.cd ~/openvswitch-2.4.0/
11../boot.sh
12.make CFLAGS='-O3 -march=native' install
13.modprobe uio
14.insmod $DPDK_BUILD/kmod/igb_uio.ko
15.$DPDK_DIR/tools/dpdk_nic_bind.py --force --bind=igb_uio eth1
16.Mount huge pages : `mount -t hugetlbfs -o pagesize=1G none
/dev/hugepages`
17.mkdir -p /usr/local/etc/openvswitch
18.mkdir -p /usr/local/var/run/openvswitch
19.ovsdb-tool create /usr/local/etc/openvswitch/conf.db
/usr/local/share/openvswitch/vswitch.ovsschema
20.ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock
--remote=db:Open_vSwitch,Open_vSwitch,manager_options --pidfile –detach
21.ovs-vsctl --no-wait init
22.ovs-vswitchd --dpdk -c 0x1 -n 4 -- unix:$DB_SOCK --pidfile –detach
23.ovs-vsctl add-br br0 -- set bridge br0 datapath_type=netdev
24.I am not sure on how to add the eth1 interface/dpdk port to the
beidge br0 now. After configuring the igb_uio module, I will not see the
eth1 interface in the ‘ifconfig -a’.
That's expected, the kernel no longer sees that device
25.But I can see the eth1 is configured as dpdk port from the below command
As the howto suggests, you should do something like:
ovs-vsctl add-port br0 dpdk0 -- set Interface dpdk0 type=dpdk
So the portnames are "dpdkX", but I'm not sure about the association
between X and the below list. I've always assumed they are numbered in
the order you bound the device to the uio driver.

26.After adding the bridge, I see the below error in the log file.

There is nothing wrong with that, you don't need the OVS kernel module
here anyway.

27.I am running the following kernel version on my Ubuntu virtual machine
root@ubuntu1404:~# uname -r

Kindly help me to identify the dpdk port & add the eth interface/dpdk
port to the Bridge?
Thanks,
Sarada
