ovirt-host requires screen package which has been deprecated in RHEL 7.6 and removed in RHEL 8 (https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/7.6_release_notes/chap-red_hat_enterprise_linux-7.6_release_notes-deprecated_packages) Separate bug will be open for Hosted Engine to fix runtime documentation currently pointing to screen to point to tmux and online documentation accordingly.
