[Xen-users] CentOS 4.4 Xen VM/VPS install on CentOS 5 (xen kernel) issues

[Senad Brkic <senadbrkic@xxxxxxxxx>]

Ok So I've been able to successfully create a CentOS5 virt-install on 
xen using LVM created partitions. But have many problems trying to 
install 4.4 (It does not work with virt-install hence you have to try 
another method). I Created a name, name-tmp, name-swap, name-root 
paritions.
I did mke2fs and mkswap no problem everything is good. I went on further 
to mount the name-tmp and name-root paritions accordingly. in order to 
copy files into the lvm partitions. Now I tried installing two ways.
Method 1: Use JailTime.org xen .imgs and then mounting the image and 
copying the files over to the /mnt/name directory (the one I mounted 
above). Everything copied over no problems at all.
I then proceeded to the final step (creating the xen config file for the 
VPS) as follows:

====================
kernel = "/boot/vmlinuz-2.6.18-8.1.1.el5xen"
name = "geotmp"
memory = "1028"
disk = ['phy:/dev/linux/geotmp,xvda1,w', 
'phy:/dev/linux/geotmp-swap,xvda2,w']
ramdisk = "/boot/kernel-geotmp.img"
root = "/dev/hda1 ro"
vif = [ '', ]

vcpus=2
on_reboot = 'restart'
on_crash = 'restart'
on_poweroff = 'restart'
====================

Somewhat similar to the script from the virt-install running servers 
plus a few changes.

Method 2:
yum -c /path/to/centos4.4/yum.conf --installroot=/mnt/<companyname> -y 
groupinstall Base
MAKEDEV -d /mnt/<companyname>/dev -x console
MAKEDEV -d /mnt/<companyname>/dev -x null
MAKEDEV -d /mnt/<companyname>/dev -x zer

This extracts and installs correctly.

We've attempted to create our own kernel with xenblk via: mkinitrd 
--with=xennet --preload=xenblk /boot/kernel-geotmp.img 2.6.18-8.1.1.el5xen
But we get the same message error when we try to use either the elfxen 
or our custom made kernel. Shown below:

So Any reason why CentOS 4.4 cannot be installed at all? Am I missing 
anything in the kernel?
