Hi Bharat,

Thank you for your response.

I am getting following errors in my worker VM (Master VM has similar errors):

I cannot see any error in the metadata service logs and I can reach the server from my VM.

I used the Openstack (pike) guide to deploy it manually without using any other system. In my setup, I have nova, neutron(Self-Service), Glance, Horizon, Keystone, Heat and Magnum running.


Kind Regards,
Navdeep

Hi Navdeep,

Have you tried logging into the master/worker node and gripping for `fail` inside /var/log/cloud-init.log and /var/log/cloud-init-output.log? Also how did you deploy your OpenStack services? 

Bharat
