I am testing this for use at work as a test environment, there I have a single server to run this on the reason I choose the Self Hosted Engine.  I guess the instructions is not clear either, i.e when i try to disk install with Cento OVA I get and error, and finally when I choose the cdrom it work fine until the end and fail to initialize /dev/mapper, etc.

Did you tried running
 yum install ovirt-engine-appliance
?

It will download a ready to use Centos base appliance with oVirt engine on it.
