I did not prefer the vendor distro. I installed the native ocata release
from scrath which i configured on myself.
I downloaded dpdk relase from source and compiled it and also binded the
interface with dpdk through ovs.
While i was installing the neutron-ovs-agent, i couldnt start ovs db with
neutron-ovs. Neutron ovs config files is not working with compiled ovs. How
can i do that?
Thank you for helping
