ok without searching to long i just restored the backup of the dual boot that i made with clone zilla before isntalling ovirt.
and then used other command that i got from a friend:
sudo yum install ovirt-engine-setup-plugin-allinone
this one worked better,
only i get now is "host installation failed"
after some googling it seemes it has to do or with the fact that i have to have static ip or something related to firewall config.
will google some more later.
heres some more info:
