My question is mainly addressed at those of you who use oVirt not only
for creating services on virtual machines.
What is your experience and what did you made?
Is there anyone who virtualized an HPC cluster?
What is for you the advantage on virtualizing a cluster?
Or, having a class with PC or Raspberry is better to use LTSP or PiNet
or virtualize desktops?
I would like to have a lot of feedback to start a discussion about the
best way to use oVirt in different contexts

Still consider myself an oVirt newb. Only been using it for a few months
but I'm liking it so far. I don't have the hardware specs in front of me
but I have a 4 node Hypervisor setup with a physical Engine host. All
running on Scientific Linux 7.
Is there anyone who virtualized an HPC cluster?
I'm still not convinced that virtualized HPC is a good idea for those
who need compute performance. Though it is getting better than when I
first heard someone say they were doing it at Supercomputing14!
What is for you the advantage on virtualizing a cluster?
Um. As a 14year HPC admin, I still say none for compute. However, I am
using oVirt to support a ton of my infrastructure services: Frontends,
Log-ins, Scheduler, Database, LDAP, ect.
I'm still learning how to set up something where my users can click a
button on a webpage and get a VM spun up for a Graphical session on
oVirt. I'm also still debating on the pros/cons for setting up oVirt
VM's for things like JupyterNotebooks/RStudio Server/ect for the "I just
want a web page to develop my code on and will submit to the cluster for
the job run" crowd.
It is a huge learning process for me. Most of the tools I've been using
have worked great for years, but it is time to update and refresh those
skills. Most of the provisioning tools I've used in the past don't work
so well with oVirt. So now I'm exploring other tools.
Foreman is and overcomplicated buggy headache, IMO. Every time I or a
coworker has tried to get it going it has been a massive
time-suck-crash-and-burn. Add to it that my current security team has
HUGE issues with Puppet (don't get me started - I like Puppet) and
building Foreman by hand with Salt is just an awful awful awful
experience I wouldn't wish on an enemy...just no. :-)
DigitalRebar was looking SUPER promising, but they recently went to a
model that MUST chat out to the Internet or it breaks itself (a complete
no-go for me). A complete shame.
So I'm back to Cobbler which is simple and works fantastically well, but
doesn't really have any integrations into oVirt (that I'm aware of). I'm
probably going to have to write something with the two API's.
Or, having a class with PC or Raspberry is better to use LTSP or
PiNet
or virtualize desktops?
Can't say. Don't mess with Raspberry Pi's
much.

Have you looked at ansible? You can make some playbooks that call the REST api
and have it deploy the VMs for you. Or if you feel like writing your own
portal you can use the Java or Python SDK to access the REST api.

2. vagrant with the oVirt provider
3. ManageIQ service portal

Provisioning VMs and customizing them using cloud-init may be a viable
option.

I'm been looking at 1.
I haven't considered 2 yet - Interesting thought that I will look into.
I just saw 3 for the first time from Pauls post and it looks very
interesting!
4 is on my potential list too.
Thanks!
