Open Stack

Hello
When set OVS_DPDK_MODE=controller_ovs

You are disabling install of ovs-dpdk on the contoler node and only installing mechanism driver.

If you want to install ovs-dpdk on the controller node you should set this value as follows

OVS_DPDK_MODE=controller_ovs_dpdk

See 
https://github.com/openstack/networking-ovs-dpdk/blob/master/doc/source/_downloads/local.conf.single_node

ovs with dpdk will be installed in /usr/bin not user local bin as it does a system wide install not a local install.

Installation documentation can be found here
https://github.com/openstack/networking-ovs-dpdk/tree/master/doc/source

the networking-ovs-dpdk repo has been recently moved from stackforge to the openstack namespace following the
retirement of stackforge.

Some like in the git repo still need to be updated to reflect this change.

Regards
sean

Hello all,

Trying to install openstack with ovs-dpdk driver from devstack.

Following is my localrc file

HOST_NAME=$(hostname)

After running ./stack.sh which was sucessful , I could see that in ml2.conf.ini file ovsdpdk was added as the mechanism driver. But the agent running was still openvswitch. Tried running ovsdpdk on q-agt screen, but failed because ovsdpdk was not installed in /usr/local/bin, which I thought devstack is supposed to do.
Tried running setup.py in networking-ovs-dpdk folder, but that also did not install ovs-dpdk in /usr/local/bin.

Am stuck here. Please guide me how to proceed further. Also the Readme in networking-ovs-dpdk folder says the instructions regarding installation are available in below links - http://git.openstack.org/cgit/stackforge/networking-ovs-dpdk/tree/doc/source/installation.rst

But no repos found there. Kindly guide me to a doc or something on how to build ovs-dpdk from devstack

Thank you,
Prathyusha
