Hi Kevin, Thanks for clarification. I was able to run OVS without DPDK immediately after the test below and the OVSDB initialization went fine without any error. I agree with you that DPDK may not have any impact on the OVSDB connectivity. But I presume that there is some piece of code that is getting invoked when DPDK is included along with the OVS build and hence preventing the OVSDB initialization.
