Hi Dan, et al,
Thanks for all your warmhearted help.
I followed Dan's suggestions as well as others' and tried again, I
see an explicit error in the overcloud: "Connection aborted.',
error(113, 'No route to host')".
(Below are the error messages and information)
I think it could because of lacking of sufficient network
configuration.
Looks the proof-of-concept use case doesn't work for me as I changed
something, such as the undercloud.conf (eg., all the IPs, etc).
So next, I would try to do the network isolation. Is there a
simple/concise example of the network configuration (
network-environment.yaml). I know that
there is a guide for this but I've lost myself in the ocean of the
information. It would be the best to start from a basic configuration,
if you could help.
Thanks,
Erming
