Recently I was working on a Dell PE1950 at work and decided to get Xen installed, so that I can create some virtual servers for our developers.
Finding out that Xen in Redhat Enterprise Linux is not so easy to download – I cannot find it from any public accessible websites, I decided to use CentOS’s yum repoes to download and install Xen. When I have CentOS yum repo created in /etc/yum.repo.d, I noticed that it cannot work in RHEL – It cannot recognize OS version without some updates of application.
That’s why I tried to convert my RHEL 5.3 to CentOS 5.3. Here are the commands that I used. You can just copy & paste:
rpm -e --nodeps redhat-release rpm -e --nodeps yum-rhn-plugin wget http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 rpm --import RPM-GPG-KEY-CentOS-5 rpm -Uvh http://mirror.centos.org/centos/5/os/x86_64/CentOS/centos-release-notes-5.3-3.x86_64.rpm rpm -Uvh http://mirror.centos.org/centos/5/os/x86_64/CentOS/centos-release-5-3.el5.centos.1.x86_64.rpm wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/yum-3.2.19-18.el5.centos.noarch.rpm
Now the convertion has finished, you can check /etc/redhat-release for an updated information, and the repo’s config directory for more details on current repoes.
Finally, dont forget to enjoy a FREE CentOS yum updating:
yum clean all yum update
I’m not quite sure if it totally works well. Nevertheless, I’ve succefully had the system updated, the Xen kernel are running smoothly as well. If I faced any issues, I’d create a new post at our redhat/centos support forum.

I read about it some days ago in another blog and the main things that you mention here are very similar
