Hi Raja, Thank you for your quick response.
More questions: ...: ) 1. What do you mean "compute node provisioning"? Are you saying vRouter-agent writes the "hugepages" and other "EAL (coremask/nic/memory...)" options to a testbed file for vRouter-dpdk process to initialize? Could I just manually config DPDK hugepage and parameters for vRouter-dpdk? If not too much trouble, could you please give me a pointer of DPDK utilities? 2. If the answer for question 1 is yes, vRouter-dpdk process is able to run by itself without vrouter-agent involved? 3. From my understanding of the CLI utility tools, it uses sandesh protocol on top of netlink to talk vRouter-dpdk process. In this case, during the develop process, developer can just use utility CLI to push config and pop the stats to verify vRourer-DPDK works as expected. Is it correct? Really appreciate your input and you have a good weekend.
