I am thoroughly confused at this point. I have three servers. One

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.
5. Profit.
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.
Controller=192.168.165.70
Node01=192.168.165.71
Node02=192.168.165.72
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 you can't ssh into them, then nothing else will work, so fix that
first. It sounds to me like you do not have ssh service configured on
your nodes/hosts. 'systemctl enable sshd; systemctl start sshd' and see
if you can now ssh into them. If so, try adding them through the Admin
portal again. If after starting the sshd service you still can't log in,
try disabling iptables temporarily (and also possibly firewalld - I've
had issues with it also).

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
