Hi It seems VXLAN tunnel is not created. Run these 2 commands on compute and neutron node. 1. Run "ovs-vsctl get Open_vSwitch . _uuid" - It will return a uuid, lets call it uuid_returned. 2. Run "ovs-vsctl set Open_vSwitch <uuid_returned> other_config:local_ip=<ip-of-your-data-interface>" - Data interface here refers to whichever interface you want data traffic to use.
This will create a tunnel between Neutron and Compute node. DHCP messages will ass through this tunnel and VMs ill get IP.
