Thank you very mucjh,  and sorry for being so lazy to search for that rpm by myself. Somehow, fedora rpms missed from my mind.
Oh boy, it requires a lot of packages. Do you think would it be a good idea to temporarily install fedora repos, do the yum installation to get the dependencoes too and then disable the repo ? I am thinking to not break the ovirt node installation.

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Cannot upload enabled repos report, is this client registered?

Thank you  !

You can fetch the release of 0.14.1 version at

You can fetch an rpm from Fedora here
