[ovirt-users] Looking to install additional packages on Ovirt Node

Hello all, Hope everyone is doing well! I would simply like to ask how it would be possible to add additional packages to the Ovirt Centos node. I followed the instructions here: https://serverfault.com/questions/927652/is-it-ok-to-add-the-epel-repo-to-a-... but I am still receiving an error that the "rear" package cannot be found (the package I am trying to install, ofcourse). Please help, I appreciate taking the time to read this. Thank you!
