[Users] How do I add a node?

I am thoroughly confused at this point. I have three servers. One for
a controller and two for nodes. These servers were used as an oVirt
environment just last week. But, now, when I try to do a fresh
installation with the exact same configuration as before, I can't add
nodes. Here is the process I used previously:
1. Install Fedora (minimum install) on each machine
2. Install tar on each node machine
3. Install the engine on the controller machine.
4. Add nodes using IP and password in the web admin interface and let
the controller build the node.
Now that procedure does not work. When I try it that way, the node
installs and then fails with an error that it can't configure the
management network on the node. I have a second working oVirt
environment, but I can't even add the nodes into that one. So, I decide
to try installing using the oVirt Quick Start document located at
http://www.ovirt.org/Quick_Start_Guide. The problem is that, there is no
"oVirt Engine" tab in the administration app. It's my understanding
from the document that this is how you tell the node which controller it
should be allowing. I can't add the nodes that I built with the oVirt
Node Installation CD. The documentation on this is so sparse that I
can't figure out what's going on. It was so easy to set up before, but
I'm having nothing but trouble, now. I have been at this for days, when
the first time took me about an hour. What am I missing? Could someone
either update the Quick Start guide, or reply with some up-to-date
instructions on how to install this environment? FYI, I am doing this
with completely fresh installs of Fedora 19. No software is being
reused or reconfigured. It's completely stock.
All are connected via the same switch. I can ping all the three machines
from each other. If I try to ssh from the controller into either of the
nodes, I get "Read from socket failed: Connection reset by peer". If I
attempt to ssh into either of the nodes from another machine on the
network, I get the same message. If I try to add either node using the
web interface, It fails with: Error while executing action: Cannot add
Host. Connecting to host via SSH has failed, verify that the host is
reachable (IP address, routable address etc.) You may refer to the
engine.log file for further details. The engine.log shows: 2013-12-13
12:21:29,714 WARN [org.ovirt.engine.core.bll.AddVdsCommand]
