Description of problem:

reason of failure - domain didn't found
enable_novajoin = True
ipa_otp = 2TzQHJvOZpEWqsCZPR7sne0yA6PzkW2cApTgoiQ6Gv6y
undercloud_hostname = undercloud-0.redhat.local
undercloud_nameservers = 10.0.0.86
overcloud_domain_name = redhat.local
after manually adding nameserver to /etc/resolv.conf and re-run command - it executed without error
Steps to Reproduce:
undercloud installation was fail
undercloud installation completed successful
didn't reproduced last two time, so you can close that issue, I'll reopen if get it again
Ok, thanks Artem. Will close, please reopen if you get it again.
However I don't think that the component should be os-net-config as os-net-config isn't populating resolv.conf.
