My enthusiasm for CentOS8 is limited. My enthusiasm for a hard migration even more so. So how much time do I have before 4.3 becomes inoperable?
oVirt 4.3.10 is approaching GA and we expect 4.3.11 to be released too before declaring 4.3 at the end of life. After that, 4.3 should keep working till CentOS 7 or any other repo on the system will break it with some incompatible change. I totally understand system administrators' point of view and how difficult it is to find a good maintenance window for a busy production environment, ensuring backups are recent enough, check new requirements matching, give it a try on a test environment if it's available and so on. That said, I would really encourage starting to plan a maintenance window for upgrading to 4.4 as soon as practical. It will be easier to help with upgrade from 4.3 at this time than 2 years from now when 4.3 can be broken (or new hardware replacement will be missing drivers on CentOS 7) and there won't be any additional release for fixing upgrade incompatibilities.
I can't speak to other people, but the lack of "ovirt-shell" for 4.4 is a deal-breaker for me to upgrade at this time, and probably for the forseeable future. I've been working on migrating my mail server for 3 years now and still haven't finished that; migrating ovirt to a new platform that requires new startup support?? Haha. Granted, I suspect SOME of the reasons I have this script might be implemented in 4.4 (e.g. auto-start of VMs). However, my understanding of the auto-start feature is that it's really an auto-restart -- it will restart a VM that was running if the datacenter crashes, but if I shut it down manually and then "reboot" the cluster, those VMs wont come back automatically. As I am on a single-host system, I need it to start from a clean shutdown and bring up all the VMs in addition to dealing with power-outage reboots. I work from the "if it aint broke, don't fix it" camp. So I think I'm going to stick with 4.3 until I can't anymore. I am happy to share my startup script if someone else wants to port it to work with 4.4. :-) -derek -- Derek Atkins 617-623-3745 derek@ihtfp.com www.ihtfp.com Computer and Internet Security Consultant
