After few days playing with ovirt+foreman I can now deploy bare metal with foreman and attach it to ovirt.
Over all it works, but there are some points to mention to beginners like me:

a) To make a auto discovery ,ovirt and deployment working together one should enable in "foreman-installer -i" following modules:
1. [\u2713] Configure foreman
2. [\u2713] Configure foreman_cli
3. [\u2713] Configure foreman_proxy
4. [\u2713] Configure puppet
6. [\u2713] Configure foreman_plugin_bootdisk
10. [\u2713] Configure foreman_plugin_dhcp_browser
12. [\u2713] Configure foreman_plugin_discovery
21. [\u2713] Configure foreman_plugin_setup
23. [\u2713] Configure foreman_plugin_templates
28. [\u2713] Configure foreman_compute_ovirt
33. [\u2713] Configure foreman_proxy_plugin_discovery

b) next follow the documentation: http://www.ovirt.org/develop/release-management/features/foreman/foremanintegration/

You should be able to see the hosts from ovirt interface.
I was not able to add an auto-discovered hosts to ovirt it always trows an exception: Failed to add Host <UNKNOWN> (User: admin@internal). probably it is a bug.

In order to add the hosts: first I provisioned the auto-discovered hosts with foreman to centos7 then over the gui in . Important here to add into installation template the path to ovirt repository: 
yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm
If your provisioned host does not know the repository you cannot add the foreman host from the ovirt gui.

Nice! Finally no sad face anymore:)
I am testing centos 7.2, with foreman 1.11

Testing  now with unattended installations on multiple vms. Works like a charm:)
Later will try on baremetals.
I need to learn how to write templates.

Don't know what distribution you're using but setting all up manually showed me that Foreman needs to be at at least 11 for the plugin to work. Otherwise it behaved in the same way for me; all fine and well until the provision plugin was installed and then *sadface* :)

Get Foreman up to version 11 and you'll be fine, is my guess.
