Strahil, see the other thread I have just opened.

It happens also to me with latest oVirt node iso for 4.4.1.1 dated 13/07

In my opinion there is a major problem with all yaml files using yum and package modules:

- yum because it expects python2 that is missing

- package because it doesn't autodetect dnf and tries yum and fails for the same reason above

A possible workaround for not modifying all yaml files is to install python2; I don't know if a channel could be enabled to have python2 back....
