What happened to oVirt engine-setup?
A while back I had oVirt 4.4.7 installed which I used for testing. For some reason that installation has died in some way, so I'm trying to install a fresh new oVirt 4.4.10. Last time I installed ovirt, it was very easy - I provisioned a couple of machines, ran engine-setup in one, answered a few questions and after a few minutes the engine was installed. Somehow this has changed and now it's really far more complicated, involving some ansible things and wanting to create VMs and ssh everywhere. Can I go back to the old/easy way of installing oVirt engine? And if so, what happened to the instructions for that?

engine-setup still works, maybe you can give move details on what went wrong? When working with the current development version, sometimes upgrading engine fails and requires manual steps, or dropping reinstalling. But since you use a stable version it should always work. Nir

So I managed to dnf install /usr/bin/engine-setup. When I ran it, it wanted to connect to an external PostgreSQL server. I'm pretty sure that never happened last time. TBH I'm also going to erase everything and start again because I've been round several loops here already. Do we recommend RHEL or CentOS as the initial OS?

For 4.4.10 your best option is RHEL 8.5. I'm not sure about the status of the RHEL clones (e.g. Rocky). In the past they were missing the advanced virtualization packages, and could be installed using Centos advanced virtuatation packages which probably are not available now (EOL). If you cannot use RHEL, Centos Stream 8 is the only option. This is the version we test on in ovirt system tests. I don't know about any issue with Centos Stream 8 for engine host, but for hosts you are stuck with qemu-6.0, since qemu-6.1 is broken, and 6.2 is not available. Nir

This is still the situation, if you install a "standalone" engine: https://www.ovirt.org/documentation/installing_ovirt_as_a_standalone_manager...

Perhaps you tried a self-hosted engine installation? https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine...

Was that a clean machine, with no left-overs? Do you see the connection attempts interactively, or only if you check the setup log?
TBH I'm also going to erase everything and start again because I've been round several loops here already.
If the machine has cruft accumulated, this is often the simplest approach, if you do not need the data there.

For 4.4.10 your best option is RHEL 8.5.
At least in theory. Do you do this yourself? Heard of others doing it? I personally only use, for development, either CentOS Stream 8 + oVirt, or RHEL+RHV. Over the years we did get reports of people using RHEL+oVirt, and also fixed a few bugs around this. But if not many people do, we'll not hear about the problems, if any, so won't fix them...

We did get here a few reports about this. I didn't try this myself. Generally speaking, it should work, with current master (4.5), and if not, should be rather easy to patch/fix. Not sure about 4.4.
they were missing the advanced virtualization packages, and could be installed using Centos advanced virtuatation packages which probably are not available now (EOL).
Not sure why you think so. Isn't that exactly the same thing people are using when using CentOS? What's the difference? Indeed, if people want to use Rocky/Alma/etc and insist on not using anything from CentOS, they'll have to rebuild these manually, unless there is already a relevant repo with these rebuilt on Rocky/Alma/etc., which I am not aware of.

Indeed. Best regards, -- Didi

I've been running oVirt on RHEL for years for development. This is basically RHV without the branding and support. Why do you think this is an unused configuration?

The difference is consuming the advanced virtualization from centos repos which may disappear since centos is EOL. I don't think we can recommend such deployment to anyone. Nir
There I always pictured you two throwing paper balls at each other across the office or going for a coffee together... In the past that difference wouldn't have mattered, I guess. But with upstream vs downstream your disagreement opens a chasm oVirt can ill afford.
