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. :-)
