HTTP Status 404 -

I am new to RHEV 3.0. I have followed these instructions to install the RHEV:

1. Install the RHEL 6.2.

2. Register with RHN.

3. Also registered with "rhn-channel -v -u "Mylogin" -a -c rhel-x86_64-server-6-beta -c rhel-x86_64-server-6-rhevm-3-beta -c rhel-x86_64-server-6-rhevm-3-jboss-5-beta -c rhel-x86_64-server-supplementary-6-beta -c rhel-x86_64-server-supplementary-6

4. I have runned the yum update and installed the updates.

5. Install using "yum install rhevm".

6. Next executed the "rhev-setup" and configured as per the general document.

7. Also, the services and database are installed & configured as the document.

I got this screen too:

Manager
* To configure additional users, first configure authentication domains using the

I am able to open the "http://manager.demo.redhat.com:8080", when I try to click on the any links in this web site, then I am getting "HTTP Status 404 - ".

For example if, I click on Administrator Portal, then I am receiving following message: 

"HTTP Status 404 - Administrator Portal"

Actually, I have tried the same setup on the Virtual Machine I was successful, but when I am trying to do the same setup on the Bare Metal system (Dell System) I am experiencing this issue.

Any help would be greatly appreciated.
