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.
oVirt node can (btw) be deployed using PXE (Foreman, Cobbler), USB and CD media, and virtual media.
That very much interests me since I utilize Cobbler currently for all of my provisioning. 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?
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.?
The pre-release build from today contains glusterfs-3.6.
Great! Thanks for the information. I've downloaded that ISO and I'm working on getting that deployed on a couple of test blades.

Thanks again!

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?
Hey,
there are some 3.5 pre-release isos available here: http://resources.ovirt.org/pub/ovirt-3.5-pre/iso/
They are quite old. The reason why there is still no Node, is that we are experiencing installation problems after CentOS 6.6 got released.
That is why there is no Node for 3.5 yet, becuase we don't want to provide a Node which is dead on arrival. This ain't fun for anyone.
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?
Yes, that will work. Due to problems mentioned above, we still need to do some fixes to the hosted-engine part of Node, but once they land, HE will work on Node.
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?
Yes, ovirt-node is not as customizable as a regular host. I.e. you can not (easily) modify the boot process, or install custom rpms.
Sometimes this is seen as a restriction, other see this as a well defined environment.
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.
No, no worries. There weren't any Node updates (besides the weekly meeting minutes) for a while.
We still traget to release Node for oVirt 3.5 ASAP.
