Open Stack

Thanks Sushma for looking into it. I figured out the cause of the
problem. It was due to misconfiguration in nova.conf of network node.
The official installation documentation is misleading when configuring
networking.
>From logs and by tracing the code, I figured out nova was using
nova-network api rather than neutron api.
It was because the documentation mentions to update nova.conf of
compute node but missed to mention that nova.conf of controller node
should also be updated to use neutron api. Added this in nova.conf at
controller node and now things work correctly.

[DEFAULT]

network_api_class = nova.network.neutronv2.api.API
security_group_api = neutron
linuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriver
firewall_driver = nova.virt.firewall.NoopFirewallDriver

[neutron]

url = http://controller:9696
auth_strategy = keystone
admin_auth_url = http://controller:35357/v2.0
admin_tenant_name = service
admin_username = neutron
admin_password = NEUTRON_PASS
