Open Stack

Hi Julia

Thanks for your response.

Earlier I was passing both ironic.yaml and ironic-overcloud.yaml located at
path /usr/share/openstack-tripleo-heat-templates/environments/services/

My current understanding now says that since I am using OVN, not OVS so I
should pass only ironic-overcloud.yaml in my deployment.

I am currently on Train Release and my default ironic-overcloud.yaml file
has no such entry
DhcpAgentNotification: true

I would add this there and re deploy the setup.

Would that be enough to make my deployment successful?

Regards
Anirudh Gupta
