[ovirt-users] Documentation

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figure out what applied, what didn't, what was out of date and a lot of 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.
