+OVS-DPDK Source build
+=====================
+
+CentOS and Oracle Linux currently do not provide packages
+for ovs with dpdk.
+The Ubuntu packages do not support UIO based drivers.
+To use the uio_pci_generic driver on Ubuntu a source build is required.
+
+Building ovs with dpdk containers from source
+---------------------------------------------
+
+- Append the following to /etc/kolla/kolla-build.conf to select the version
+  of ovs and dpdk to use for your source build.
+
+kolla-build.conf
