I apologise that this issue wasn't taken care of yet. It is clear that
the priorities of developers shifted towards work on features in 3.3
release, which feature freeze is happening in about 2 weeks, so you can
understand the time pressure they all have. There's no need to be angry
about that. It is an open source project and as resources for the
development are limited, we're trying to do our best to cover as much
issues as possible. This can lead to situations as this issue, which
may be left behind for some time.
I´m not angry, as I stated before, I´m more confused, and maybe a little disappointed that important(in my opinion) pieces of a projects continuum have been ignored like that. I´m having a hard time understanding the reasoning behind the priorities that have made this issue appear. In my mind, making sure that users of any project are able to follow between minor upgrades is a given, with a schedule like; 1) Feature freeze, 2) Fix release blockers (upgrading being one of them), 3) Release, in that order. Now what´s happening is that you are kind of hoping to drag this out until the problem goes away by itself when you decide it´s time to stop supporting 3.1.
That said, the process for upgrading the oVirt 3.1 on Fedora 17 to
oVirt 3.2 on Fedora 18 is complex and non-trivial, that's why it is
taking time to resolve all the issues that come up in the process.
If this matter is not extremely urgent, we are currently working on a
tool that may make this upgrade easier, albeit, maybe, not completely
automatic.
On the other hand, if this is a completely and utterly urgent, we may
try to guide you through possible manual attempts to perform the
upgrade. Mind though, that they weren't thoroughly tested, and not
promised to go smoothly or even work, and we may have to think about
possible alternative solutions on the go.
Straight answer: Am I ever going to be able to upgrade from 3.1 to 3.2?
My concern (fear) is about being left behind, abandoned. It makes me feel non-important. Just like any admin, the work put down to make Templates, to set up quotas, create VMPools, a dozen of guests. And then have to export everything (nullifying the idea of "Thin Provisioning"), redo every Role, reset every permission, quota, and so on, isn´t (in my opinion) viable in the long run for oVirt as a project to demand. That´s why I had the notion that upgrading surely had to be a high priority. Was I wrong about that?
