In EL 8 , there is no 'default' python. You can use both. My choice would be ansible because APIs change , but also ansible modules are updated. If you create your own script , you will have to take care about the updates, while with ansible - you just update the relevan packages :)

No match for argument: python There are following alternatives for "python": python2, python36, python38 Error: Unable to find a match: python 2) When you have three nodes.. one is set to host the ovirt-engine active, and another as backup. If this is added to rc.local. Of the two nodes hosting HA for oVirt-engine.. node which boots first will host (or so it seems). I think if I add this to both those hosts .. it will not create issues. Any thoughts?
