[Xen-users] device model failure: no longer running;

[Mike Mildner <m.mildner@xxxxxxxxxxxxxxxxxxx>]

hi xen-list,

i have installed xen-3.3.1 from source on a core2duo. the xen kernel 
boot fine.
i create a file image with dd and a simple domU config file for windowsXP:
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"
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
builder = 'hvm'
memory = 512
vcpus = 1
shadow_memory = 8
#vif = [ 'type=ioemu,bridge=xenbr0' ]
acpi = 1
apic = 0
disk = ['file:/root/xenXP.img,ioemu:hda,w','phy:/dev/hdc,ioemu:hdc,r']
name = 'xenXPtest'
cdrom = '/dev/hdc'
boot="d"
vnc=1
#vncviewer=1
vncpasswd='test'

then i use 'xm create xenXP.cfg'
the windows cd start to boot (beginns to spinning in drive) but stop 
immediately. )-:
also 'xm list' shows for this time a domU but only some seconds. is it a 
problem to use a 64bit dom0 for 32bit domU? the xen install script have 
only a 64bit binary from qemu-dm installed. i'm confused about the 
error:  domain xenXPtest: device model failure: no longer running; (see 
log file below) here some parts from xend.log:
