I launch a VM Instance with Havana multinode Setup. After launching Vm Instance in logs i am getting Metadata error and i am not able to ping/ssh to Vm Instance from my Controller Node. I check the Logs in Network node and compute node and i found below errors in openvswitchagent.log & dhcpagent.log.
In Network Node:
