RE: [Xen-users] RE: [Fedora-xen] Difficulties using the Fedora Core 4

["Petersson, Mats" <mats.petersson@xxxxxxx>]

Whilst I'm sure that Redhat is working on a publicly available RPM (or
similar) that you can install straight off, I would suggest that you
build your own Xen/Dom0 kernel. It's not TERRIBLY hard - although
there's some quirks and catches. This works for me:
Download some version of Xen from www.xensource.com (snapshot or 3.0.0
release).
Unpack into xen-<ver>
cd xen-<ver> 
make world
<wait for some time>
cd *0   <this takes you to the Dom0 core>
make ARCH=xen menuconfig
<I personally turn off modules and enable devfs + smp, but you may want
other configurations>
cd .. 
make install
cd dist
./install.sh
<edit grub.conf or similar to have lines like this:
title Xen-32
        root (hd0,0)
        kernel (hd0,0)/boot/xen-3.0-devel.gz dom0_mem=200000
com1=115200,8n1 console=vga,com1 sync_console
        module (hd0,0)/boot/vmlinuz-2.6.12-xen0 root=/dev/hda1
console=ttyS0
>

If you use modules, you'll need to add a line saying "module
(hd0,0)/boot/initrd-xxxx", and you need to create the initial ramdisk
with "mkinitrd" in your linux-*0 directory. It's not hard, but to me
it's easier to just build a kernel with all the drivers in one file -
you loose a chunk of memory from this, of course. My kernel is a bit
over 4MB uncompressed code and a good megabyte of data on top of that.  

Of course, your hard-disk layout may be different - adjust accordingly. 

I hope this helps.
