Hi,
That manual is only for installing OVS and linking it to DPDK.
However, you need to install DPDK on your own before installing OVS with
DPDK.
download DPDK from here: http://dpdk.org/download
follow instructions for the installation procedure (not that difficult -
less commands needed than for OVS :) ).
For using OVS with DPDK, you need to insert the userspace IO driver
provided by DPDK, then enable this driver on the interfaces you want to
use with DPDK (this binding script will be available under:
your-dpdk-directory/tools/dpdk_nic_bind.py
argument --status will print out which port is used by the kernel driver
and the dpdk driver.
you could also find more details under http://dpdk.org/download on how
to bind your interface to DPDK driver.

Hi,
I built OVS+DPDK from source. I use OVS 2.5.0 and DPDK 2.2.0, the
build environment is RHEL 7.2. I try to follow this instruction,
https://github.com/openvswitch/ovs/blob/master/INSTALL.Fedora.md
However, it reports:
/make rpm-fedora/
/make: *** No rule to make target `rpm-fedora'. Stop./
So, try commands as follow,
./boot.sh
./configure
rpmbuild -bb rhel/openvswitch-fedora.spec --with dpdk
Finally, I got following RPMs,
/RPMS/x86_64/openvswitch-2.5.0.el7.x86_64.rpm/
/RPMS/noarch/openvswitch-2.5.0.el7.noarch./
/RPMS/noarch/python-openvswitch-2.5.0.el7.noarch.rpm/
/RPMS/noarch/openvswitch-test-2.5.0.el7.noarch.rpm/
/RPMS/x86_64/openvswitch-devel-2.5.0.el7.x86_64.rpm/
/RPMS/x86_64/openvswitch-ovn-2.5.0.el7.x86_64.rpm/
/RPMS/x86_64/openvswitch-debuginfo-2.5.0.el7.x86_64.rpm/
Then, I installed rpm RPMS/x86_64/openvswitch-2.5.0.el7.x86_64.rpm.
I can create bridge and ports, but dpdk interface does not exist.
/ovs-vsctl get Open_vSwitch . iface_types/
/[geneve, gre, internal, ipsec_gre, "l3gre", lisp, patch, stt, system,
tap, vxlan ]/
How can I enable dpdk interface or Is there anything wrong with my
build procedure?
BRs,
Binghan
