Hi,
Real hardware: what I meant to say was I have 4 hosts (not vm's). If I understand you correctly, I should install oVirt Node (using the iso) on 3 of my hosts & the hosted engine runs as a vm on "Host 1"?
Hosted engine runs as VM on one of the hosts. But not necessarily on the first one (it can even move if it decides so).
Why can't the hosted engine run on its own host?
Well you can always run the engine on a physical node directly too. The question is why would you want that when hosted engine gives you fail-over and reliability features. So I would install Node on all four hosts, enable all of them for hosted engine and enable three of them for Gluster if hyperconverged is what your want.

Sandro, thx for the reply. Once I get comfortable with oVirt + CentOS, then I'll go & use Fedora 25/26 and contribute!

I want to test oVirt with real hardware, no more nested VMs. 3 hosts, each vm will be Fedora (maybe CentOS, I prefer Fedora)
Please note Fedora support within oVirt project is a best-effort task. There's no testing of oVirt on Fedora done by the core development team. That said, I would be happy if you contribute fedora testing :-)
I'm not sure to understand what you're looking into now since you talk about real hardware and VMs in the same sentence. Suggested minimal deployment is 3 real hardware hosts as hypervisor nodes and hosted engine with hyperconverged deployment. You can use oVirt Node iso in order to do the whole deployment using cockpit.
What is the install process?

Sandro, If & when one decides to "graduate" & use real hardware, what is the install process?
The install process depends on how you want to design your lab . You can have a small deployment with just 3 hosts in hyperconverged setup or a large datacenter with 200 hypervisors and one or more dedicated SAN for the storage. If you go with an hyperconverged setup, you can install oVirt Node on 3 hosts and then on one of them use cockpit to deploy gluster and hosted engine on top of it in hyperconverged mode.
You can find an installation guide here: http://www.ovirt.org/documentation/install-guide/Installation_Guide/ [1]
Is the gluster part still automated or that has to be done manually?
If you go with hyperconverged mode it's now automated. You can find more info here:
http://www.ovirt.org/develop/release-management/features/gluster/gdeploy-coc...
[2] Sahina, please ensure above link is updated. I see it shows the feature still in WIP while it's been released.
Another question, what type of use cases & jobs is oVirt being deployed in & how are people getting tech support?
About use cases for oVirt you can find some examples here: http://www.ovirt.org/community/user-stories/users-and-providers/ [3] If you want dedicated support, I would recommend to get a Red Hat Virtualization (which is oVirt with technical support and some additions) subscription getting Red Hat support. Another place to get support if you stay with oVirt is the community: this mailing list, the IRC channel and social media, have a look here for other contacts: http://www.ovirt.org/community/ [4]

I assume people are using oVirt in production?
Sure, I was just wondering why you were running in nested virtualization :-) Being your use case a "playground" environment, I can suggest you to have a look at Lago http://lago.readthedocs.io/en/stable/ [5] [1] and at Lago demo at https://github.com/lago-project/lago-demo [6] [2] to help you preparing an isolated test environment for your learning.

I have one CentOS7 host (physical) & 3x oVirt nodes 4.1.2 (these are vm's).
Hi, can you please share the use case for this setup?
I have installed vdsm-hook-nestedvm on the host.
Should I install vdsm-hook-macspoof on the 3x node vm's? _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users [8] [4] [2] [2]
