Hi,
I can't see the entry for
vmm = xen.gz
or similar.
You need a special elilo with support for the xen hypervisor. This extended 
elilo starts the image defined with vmm (the hypervior) first.
Attached is a document written by anyone from the list - please see part "Boot 
Xen & Domain0" which describes this stuff.
Hope this helps!
Dietmar.
=================================
# Recipe of Booting up Xen/dom0/domU on IA64 system
# 06/02/2006 Written by Xen-ia64-devel community.
My enviroment is;
 Machine : Tiger4
 Domain0 OS : RHEL4 U2
 DomainU OS : RHEL4 U2
----------------------------
Build xen
 1. Download source
 # hg clone http://xenbits.xensource.com/ext/xen-ia64-unstable.hg
 2. # make world
 3. # make install-tools
 4. copy kernels and xen
 # cp xen/xen.gz /boot/efi/efi/redhat/
 # cp 
linux-2.6.16.13-xen/vmlinux.gz /boot/efi/efi/redhat/vmlinuz-2.6.16.13-xen
 5. make initrd for Dom0/DomU
 # cd linux-2.6.16.13-xen/
 # make modules_install
 # mkinitrd -f /boot/efi/efi/redhat/initrd-2.6.16.13-xen.img 
2.6.16.13-xen --builtin mptbase --builtin mptscsih
 # cd ..
---------------------------------
Make OSimg for DomU
 1. make file
 # dd if=/dev/zero of=/root/rhel4.img bs=1M seek=4096 count=0
 # mke2fs -F -j /root/rhel4.img
 # mount -o loop /root/rhel4.img /mnt
 # cp -ax /{dev,var,etc,usr,bin,sbin,lib} /mnt
 # mkdir /mnt/{root,proc,sys,home,tmp}
 2. modify DomU's fstab
 # vi /mnt/etc/fstab 
 /dev/hda1 / ext3 defaults 1 1
 none /dev/pts devpts gid=5,mode=620 0 0
 none /dev/shm tmpfs defaults 0 0
 none /proc proc defaults 0 0
 none /sys sysfs defaults 0 0
 3. modify inittab (runlevel)
 # vi /mnt/etc/inittab
 id:3:initdefault:
 
 4. add tty0 into /etc/securetty
 # vi /mnt/etc/securetty (add tty0)
 
 5. umount
 # umount /mnt
 
-------------------------------------
Boot Xen & Domain0
 1. replace elilo
 download from the below
 http://elilo.sourceforge.net/cgi-bin/blosxom
 and copy into /boot/efi/efi/redhat/
 # cp elilo-3.6-ia64.efi /boot/efi/efi/redhat/elilo.efi
 
 
 2. modify elilo.conf (like the below)
 # vi /boot/efi/efi/redhat/elilo.conf
 prompt
 timeout=20
 default=xen
 relocatable
 
 image=vmlinuz-2.6.16.13-xen
 label=xen
 vmm=xen.gz
 initrd=initrd-2.6.16.13-xen.img
 read-only
 append="com2=115200,8n1 console=com2 dom0_mem=1G -- nomca nosmp 
console=tty0 console=ttyS1,115200,8n1 rhgb root=/dev/sda2"
-------------------------------------
Boot DomainU
 1. make config of DomU
 # vi /etc/xen/rhel4
 kernel = "/boot/efi/efi/redhat/vmlinuz-2.6.16.13-xen"
 ramdisk = "/boot/efi/efi/redhat/initrd-2.6.16.13-xen.img"
 memory = 384
 name = "rhel4"
 disk = [ 'file:/root/rhel4.img,hda1,w' ]
 root = "/dev/hda1 ro"
 extra = "nomca console=tty0 3"
 
 2. After boot xen and dom0, start xend
 # /etc/init.d/xend start
 ( In the debugging case, # XEND_DEBUG=1 xend trace_start )
 
 3. start domU
 # xm create -c rhel4
