Latest ovirt-node release/installation
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, Chris

Can't answer the others but here is my try on number three: You lose the functionality of customizing your node in an easy way, in a "full os" install you don't need many packages as well: minimal EL6/7 and the added ovirt stuff (vdsm/mom). also installation is easy, setup your host the way you like it, add ovirt repo, let engine install, finished. I'm still observing node, but imho it's kind of it's own distro, you have many limitations, e.g. it's designed to be read only for most files (making it more secure) which creates more trouble to "persist" changes. I honestly don't think there is enough dev power (in terms of manpower) for node, too. As I said, it's like a fork of el6/fedora, but with just about 5-10 devs. I'm running very well with el6 hosts atm, I would discourage the use of fedora nodes as well, because there where multiple reports of broken hosts after package upgrades in fedora (imho that's a no brainer, as fedora is bleeding edge and thus more breakage does occur).

I take the liberty to add Fabian to this thread. Here is the link to the most current node release: http://resources.ovirt.org/pub/ovirt-3.5-pre/iso/ovirt-node-iso-3.5.0.ovirt3... see [1]
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?
Be aware, this is not a stable release ATM but provides HE features. This works quite cleverly by fetching an OVF offline engine install.
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?
Here I go along with Sven's notes for most of the part. The node project is quite ambitious. You might have some troubles with special hardware. Esp. SELinux is a real challenge, also EL7 with systemd. But if you want (many) lightweight hosts witch standard hardware and an easy deployment cycle, node is for you. Give it a try and see if it suits your needs and share your experience...
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.

[1] Fabian's announcement Hey, to be able to give Node a go on the oVirt 3.5 TestDay, we provide a fresh build of Node including the 3.5rc2 package here: http://resources.ovirt.org/pub/ovirt-3.5-pre/iso/ovirt-node-iso-3.5.0.ovirt3... We did not see any SELinux denials, but if you experience any problems, please try to install Node in permissive mode by appending enfcoring=0 during the installation. -- Daniel Helgenberger m box bewegtbild GmbH P: +49/30/2408781-22 F: +49/30/2408781-10 ACKERSTR. 19 D-10115 BERLIN www.m-box.de www.monkeymen.tv Geschäftsführer: Martin Retschitzegger / Michaela Göllner Handeslregister: Amtsgericht Charlottenburg / HRB 112767

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. - fabian

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!

oVirt node can (btw) be deployed using PXE (Foreman, Cobbler), USB and CD media, and virtual media.

The pre-release build from today contains glusterfs-3.6. - fabian

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?

Great! Thanks for the information. I've downloaded that ISO and I'm working on getting that deployed on a couple of test blades.

Hey, for Node it's a bit different. You can just use the kernel+initrd and some kernel arguments to deploy it via PXE. No kickstart needed. Our documentation is a bit lacking the details, but you can consult this docs: http://red.ht/1xNNXak http://red.ht/1vkmLRc The should work for Node as well.
