Hi Om Prakash,
Based on the shared nova VM instance console log output, VM instance has
initiated DHCP discover request but we need to know whether dhcp
agent(q-dhcp) is sending dhcp offer response properly back to the VM or
not. To confirm this please do packet (using tcpdump) capture of the VM tap
interface also please confirm whether openstack q-dhcp service is up and
running properly without any issues. Please refer the below sample q-dhcp
service running status from the openstack cli command response.
stack@osc-pike-ubuntu16:~$ openstack network agent list
+--------------------------------------+----------------+-------------------+-------------------+-------+-------+------------------------------+
| ID | Agent Type | Host
