Please check if DHCP packets on compute and network node using tcpdump and also check that they contain valid VLAN tagging information.

Subject: [Openstack] Unable to assign ip to instance in compute node-2


I have  configured  3 node  setup. Able to access instance form external network and internal network .
i have attached another compute node in the current 3 node setup .
Launched instance in compute-2  but instance is not able to get the internal ip address  through dhcp .
Is there any additional configuration required when i added new compute node .
How can i debug this .

 Able to see IP for that instance when launching nova list command on controller node as well on dash board.
user at user-ThinkCentre-M73:~$ nova list
