..snippity... with regards to oVirt 3.5
that’s a really old version….
I know I'll catch heat for this, but by "old" you mean like December of
2015? Just trying put things into perspective. Thus it goes with the
ancient and decrepit Red Hat Ent. 7.1 days, right?
Hehe. It’s not about using it, rather I was referring to the fact that we
stopped developing it, stopped fixing even critical security issues. Same
for 3.6, and 4.0.
I know, I know, FOSS... the only thing worse than running today's code is
Well, there is only a limited amount of resources you can devote to
actively maintain branches/releases
We typically do that for two versions, covering roughly 1,5 years
We still run a 3.5 oVirt in our dev lab, btw. But I would not have set
that up (not that I would have recommended oVirt to begin with), preferring
3.4 at the time. I would have waited for 3.6.
With that said, 3.5 isn't exactly on the "stable line" to Red Hat
Virtualization, that was 3.4 and then 3.6.
Some people can't afford major (downtime) upgrades every 3-6 months or so.
That’s why we do not really require it and still support 3.6 cluster compat
in 4.2, so that does give you longer time to update. And even the cluster
upgrades are rolling, we do not require any real downtime other than for
rebooting individual VMs and some spare capacity to migrate workloads to
during host upgrade.
But, arguably, maybe we shouldn't be running oVirt. Maybe it's not
designed for "production".
I guess oVirt isn't really for production by definition, but many of us are
So... not really a "ding" against oVirt developers, it's just a rapidly
moving target with the normal risks that come with that. People just need
to understand that.
Absolutely. People should understand the difference between a GA and a
zstream update 6 months later. Every sw has bugs.
But I would argue we do actually have quite a long supported versions, when
compared to a $random project.
And then yes, we do have a longer support for Red Hat Virtualization, but
again in general I would doubt you can find many similar commercial
products being _actively_ supported for more than few years
And with that said, the fact that many of us are running those ancient
decrepit evil versions of oVirt in production today, is actually a
testimony to its quality. Good job devs!
