RHEL OSP installer Issues

Hi,

I am trying to deploy RHEL Openstack 3 node configuration. I have installed RHEL OSP installer and started the deployment.

I am facing following issue :

1) On the controller node, once OS is installed it asked for subscription manager username and password but shows an Network error and no further commands are run. Is it needed for controller node to subscribe itself with RHEL? Also how the external network will be accessed in this case?

2) On the compute node I am facing following issue:

“There was an error rendering the Kickstart RHEL default template: undefined method ‘has_vlanid?’ for NilClass::Jail (NilClass)”

Could please suggest what is wrong in both cases?
