[Xen-users] misled with Installing xen 3.3.0 onto CentOS 5.2

["Eric Jansen" <janseneric@xxxxxxxxx>]

I put my all braveries to install Xen 3.3.0 on Centos 5.2 although I have no idea at all on how to install kernel on Linux and moreover, installing xen. In this case I am quite newbie.
Be honest, I do not know whether to upgrade to Xen 3.3.0, necessary to install both linux-2.6.18-xen.3.3.0. and xen.3.3.0 or JUST xen.3.3.0, SO I decided to install both of them!
I follow the steps from the maillist before and I have no idea how will the end.

I follow the step like following:
1. I download from www.xen.org/download/linux-2.6.18-xen.3.3.0.tar.gz

2. then wget http://bits.xensource.com/oss-xen/release/3.3.0/xen-3.3.0.tar.gz

3. tar -xvf xen-3.3.0.tar.gz and tar -xvf linux-2.6.18-xen.3.3.0.tar.gz

4. cd linux-2.6.18-xen.3.3.0

    make menuconfig
    ----> The menu shown up, and I just checked what I thought was necessary, almost all of them I check it with "M" or  "*" randomly and I left it with memory support 64GB for PAE

    make modules_install
    make install

5. cd xen-3.3.0
    make tools
    make xen
    make install-tools
    make install-xen
    ---> I found something awkward here!!
    ---> thus, I asked the channel xen in freenode, one operator there asked me to do :
         make world
    ----> afterthat I did like his sayings, to do:
         make xen
         make install-xen
    -----> It seemed working till this step

6. When I did with ls -lu /boot, the result as followings: (the ones with bold are the results from the guidances above)

-------------------------------------------------------------------------------------------------------
Until this step, I have no idea what should I do... I have no idea how to edit the grub for the xen 3.3.0 new kernel. According to the guidance, I need to edit myself the initrd..
I've tried it but it failed cause (probably) I am on the 2.6.18-92.el5xen world, thus, it won't be able to produce new initrd for xen 3.3.0 kernel with it. 
Then, I reboot and went to 2.6.18.8 in case to make initrd but it was unable to continue after entering (like the installation was not completed yet, it was just stucked and asking me to restart). Now the problems are I cannot get into 2.6.18-92.el5xen anymore, it is also stucked
Obviously, just say I do not either how to do it. 
So what steps am I missing?
Thanks before
