I want to set up a small cluster consisting of 2 Hypervisor nodes (self-hosted engine) with shared storage (SAN, ISCSI). According to https://www.ovirt.org/download/ the following Operating Systems are supported with the latest oVirt version (4.4.4): - Red Hat Enterprise Linux 8.3 - CentOS Linux 8.3 - CentOS Stream (Tech Preview) My doubts are: - RHEL 8.3 is free to use up tp 16 hosts, but until when? Red Hat can decide at anytime to change their subscription program. - CentOS Linux is no more, support will stop at the end of 2021. - CentOS Stream is in Tech Preview. I don't like running production environments on "tech preview / beta" versions. I would say CentOS 7, it will receive maintenance updates up to 2024, and switch to RHEL in 2024 if the free-to-use program is still active. Unfortunately, CentOS 7 seems not to be supported. On what Operating System are you running oVirt 4.4.4 and why? Any feedback and advice is welcome. Thanks!
