Yeah, its frustrating for sure as I spent a lot of wasted time trying to
figure out what applied, what didn't, what was out of date and a lot of
what did apply assumed I already knew parts I needed. I came from
VMware and Hyper-V worlds and really like oVirt and what it's doing but
the documentation can be frustrating for sure. Unfortunately, that
seems to be the way of a lot of OpenSource and along with that very few
people like to do documentation and when they do it's from the
perspective of someone who already knows the answers so it really
doesn't help a brand new person who has no clue. I had to do several
hosted engine installs before I got it working (the stupid installer
can't recover from an error so it makes you start over) on 3.6 (thanks
be to VMware Workstation that let me start over <G>). I took a lot of
notes and when I get time I'll post them. I know some will say we
should contribute to the docs but I know I already have a full schedule
with work and family and can't do anymore.
I've found this mailing list is the best source of information and
sometimes they can link to sources we haven't found. The people in this
group are really knowledgeable and helpful so until the do get updated
docs ask here.

As a prospective user of oVirt I have noticed quite a lot of glaring
problems with the documentation, is it still being maintained? Since
outdated or incomplete documentation is often worse than nothing, a
possible solution would be to just link to the official Red Hat
Virtualization documentation.
Here are some examples I found after looking for less than 5 minutes:
1.
http://www.ovirt.org/documentation/
The top of this web page has two videos from 2012. The left one "oVirt
Open Virtualization Basics -- Single Machine Install" is a guide for
the all in one install. This is misleading as it no longer possible
to perform an all in one install since 3.6, and in general it would
appear the oVirt project does not support deploying oVirt to a single
machine. The right video is a guide on creating VMs using the GUI from
2012 which has since changed.
Overall both videos should be removed from the Documentation page as
they only confuse and mislead new users. I, and I am sure many other
users would greatly appreciate more current video guides.
2.
https://www.ovirt.org/documentation/how-to/hosted-engine/#fresh-install
Under the notes for this there is the following passage:
“Although hosted-engine and engine-setup use different wording for the
admin password ("'admin@internal' user password" vs "Engine admin
password"), they are asking for the same thing. If you enter different
passwords, the hosted-engine setup will fail.”
Why is the wording different? This appears to be entirely
unnecessary, and also confusing as to why it is asking for the
password a second time at all.
3.
https://www.ovirt.org/documentation/how-to/hosted-engine/#fresh-install
After finishing the hosted engine deployment script the guide states:
“After completing the OS installation on the VM, return to the host
and continue. The installer on the host will sync with the VM and ask
for the engine to be installed on the new VM:”
It is unclear how you are expected to access the VM, is the Web UI up
at this point? Do you need to use virsh to connect to the VM? The
guide should be explicit.

I. The documentation discusses Fedora 19, Fedora is currently on
version 24 and 19 is EOL.
II. Under “Storage and Networking” there is no mention that oVirt
requires at least 3 GlusterFS bricks to achieve quorum.
III. Under “Virtual Machines” there is no mention of Windows 10,
Fedora past version 20, or RHEL/CentOS 7.X.
