As the three servers are Centos8 minimal installs. + oVirt HCI wizard to keep them lean and mean... a couple questions
1) which version of python would I need for this (note in script about python 2 but isn't that deprecated?) [root@thor /]# yum install python Last metadata expiration check: 2:29:38 ago on Wed 30 Sep 2020 01:18:32 PM EDT. 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?
