Description of problem: Per summary, embedded ansible will not start if the hostname of the appliance has an underscore. (or otherwise fails an apparently buggy regexp. Version-Release number of selected component (if applicable): 5.9.1.2.20180321221247_67fd99d How reproducible: Always Steps to Reproduce: 1. set hostname to something like "cf_lab1" 2. Attempt to start embedded ansible role 3. See failures in log. I tried with both "cf_lab1" and "cf_lab1.fake", which failed. "cflab1.fake" worked.

https://github.com/rest-client/rest-client/issues/556 may be the problem (and have a workaroud)
The issue is that underscore is not allowed in the hostname of a URI. Hostnames can include alphanumeric characters and hyphen. I already added a workaround for this issue in https://github.com/ManageIQ/manageiq/pull/16913 and https://bugzilla.redhat.com/show_bug.cgi?id=1537566 From RFC 3986 section 3.2.2: https://tools.ietf.org/html/rfc3986#section-3.2.2 A registered name intended for lookup in the DNS uses the syntax defined in Section 3.5 of [RFC1034] and Section 2.1 of [RFC1123]. Such a name consists of a sequence of domain labels separated by ".", each domain label starting and ending with an alphanumeric character and possibly also containing "-" characters. *** This bug has been marked as a duplicate of bug 1537566 ***
