3) Is there any functionality that one would be losing out on by deploying oVirt via oVirt-node vs. using full-OS installation? Which is the more recommended?

I sincerely hope that this is not answered elsewhere as I've done several searches and have yet to find a solid answer. I have three (what I believe to be) basic questions (with perhaps some subs there): 1) What is the latest oVirt-node release and where would one download it (I appear to only see 3.4 -based releases of the ISO available)? It is 3.5-based and/or is there an upgrade path? Which glusterfs release is currently included with oVirt-node?

2) As I understand it, newer releases of oVirt-node allow you to do an installation of the self-hosted engine at this time. Is that correct?

3) Is there any functionality that one would be losing out on by deploying oVirt via oVirt-node vs. using full-OS installation? Which is the more recommended?

Again, I apologize if these questions are covered somewhere, but I felt like asking them in a direct fashion so as to clear up my own ignorance. I appreciate any feedback and information that you could share.

Thanks to everyone for the answers. That helps clarify some basics for me. I prefer to try and implement ovirt-node for the reasons stated above (small, defined OS with a smaller security/management footprint), but now I debate using CentOS 6 or RHEL 6. I feel that oVirt-node is very important to being able to get an environment up and running securely without too much overhead, but perhaps I need to consider minimal OS installs + latest gluster release + 3.5 oVirt at this time.

One thing I was curious about is gluster support in oVirt-node. What is the current status as far as glusterfs version and saving settings, etc.?

Thanks again!

I would assume that basically one would kickstart it like any other RHEL-based release. Are you aware of any document that describes Cobbler+oVirt-Node by chance?

I've downloaded that ISO and I'm working on getting that deployed on a couple of test blades.
