[ovirt-users] Foreman: Add external provider (Failed with error PROVIDER_FAILURE and code 5050)

[Daniel Helgenberger]

Answering my own question; and maybe a very obvious cause for the 
failing provider: the missing provider plugin in forman!
So one needs to do:

yum install ruby193-rubygem-ovirt_provision_plugin

on the foreman host.

After that, the connection test in the engine comes up positive. Sadly, 
this is not documented anywhere; only on the GitHub repo readme [1]. 
This is also a little bit outdated, as the rbovirt dependency is 
resolved now automatically.

Also, but I am not sure, the porvider lugin needs the foreman_discovery 
plugin to work:

yum install ruby193-rubygem-foreman_discovery
