It might be OVS-1.9.0 does not support multicore.  Try to use a later version.

Subject: [ovs-discuss] Multi core on OVS

Basic introduction
(i) I work with OVS-1.9.0.
(ii) I have added a function call in OVS dataplane processing which
additionally takes 16microseconds to 50 microseconds.
Issue
 - I am trying to distribute the load (software interrupt processing) across both the \
cores. Steps I follow are :

(i) Obtain interrupt number for the ethernet device.
(ii) Make the smp_affinity parameter of ethernet device to 0x03 i.e.
to use both the cores, so that at high data rates both the cores are
utilized but i still see only one core reaching 100%.

Can someone hint at how i should go further.
