@purnendu15 , From error, it looks like sriov is throwing error while it is trying to get an ip for pod. Can u recheck the sriov install part and interface it is mapped to. One way to verify sriov setup aspect is to bringup kubernetes and only sriov as network plugin (without genie and others) and check whether pod can get ip from sriov. If ok, with genie also, we should be able to acheive same. Let us know if u get some detail on this and we shall surely continue to analyse further and help you to resolve your issue
