I have DVR network configured one controller and two compute node.

I have neutron-metadata-agent.service  running on compute nodes but
its metadata-agent.ini file is default (nothing configured) should i
point this to controller node like nova_metadata_ip =
controller.ip.addess

I am getting following error


VM# curl http://169.254.169.254/meta-data
curl http://169.254.169.254/latest
