Has anyone been able to get a Xen Windows domU to install or work properly on CentOS 5?  I'm trying to do that now.  It's able to boot and start he installation (from ISO), but after partitioning the disk and copying a few files to the hard drive, it cannot boot into the graphical installer.  This is the config file I'm using:

import os, re
arch = os.uname()[4]
if re.search('64', arch):
    arch_libdir = 'lib64'
else:
    arch_libdir = 'lib'

kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 1024
shadow_memory = 520
name = "acw2"
vcpus=4
vif = [ 'type=ioemu, mac=00:18:32:6c:00:ba, bridge=xenbr0' ]
disk = [ 'phy:/dev/acw1/acw2,ioemu:hda,w', 'file:/isos/en_ws_2003_std_sp1_vl.iso,ioemu:hdc:cdrom,r' ]
cdrom='/dev/hdc'
boot='dca'
#boot='a'
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
sdl=0
vnclisten="10.1.34.108 "
vnc=1
vncdisplay=2
vncconsole=0
vncpasswd=''
stdvga=1
serial='pty'
on_reboot = 'preserve'
on_crash = 'preserve'
