Sorry if this is unclear. But:

For the "Test" button in "Add external provider" in Engine GUI to work, 
one *needs* do this on the Foreman host:
# yum install ruby193-rubygem-ovirt_provision_plugin

If this this assumption is true (it was for me reproducible) 
Foreman/oVirt communication will fail.
Therefore I am still convinced it is reasonable to put this as the first 
step before ever trying to add the provider in oVirt.*

The other things, like bare metal prov. and so on are optional.
Installing the oVirt - provider on the Foreman host is not.

To make this clear, this is not correct since the default foreman setup 
does not have the oVirt provider module installed. There are some use 
cases where Foreman is added because of oVirt, and some will have 
Foreman already runningin their infra. In this case, foreman-installer 
was already run.

* At least I was struggling with this requirement. Truth be told, 
Foreman was one point on a (very long) check list of mine; so I might 
not have paid proper attention to the details. OTOH the document 
suggested a strait forward approach with nice details and icons on how 
to do it oVirt. For instance, when I got to the section "Bare Metal 
Provisioning" I looked briefly over the requirements and decided to do 
this later on. Wrong here, since there is what I need to get it running 
in the first place!
The other issue, having two different (one obsolete) ForemanIntegration 
docs, is solved now.
