[Xen-users] Problem with running win xp on HVM

[Lists <xen@xxxxxxxxxxxxx>]

Hello,

I have a problem trying to run 32-bit windows xp on xen 3.2.1 (compiled from 
vanilla xen-3.2.1 and linux-2.6.18-hex.hg).
After an xm create the machine starts and immediately powers off:

[...]
[2008-07-29 14:59:05 4509] INFO (XendDomain:1165) Domain xp1 (19) unpaused.
[2008-07-29 14:59:05 4509] INFO (XendDomainInfo:1283) Domain has shutdown: 
name=xp1 id=19 reason=poweroff.
[...]

I've tried adding a script=/bin/true to the vif line - this causes a problem 
with hotplug and stalls the machine a bit before the "Domain has shutdown" line 
in the logs. During this stall i can connect via vnc, but all i get is a white 
screen (no bios messages etc).
A google search reveals similar problems, but i haven't seen a solution posted.

This machine runs three paravirtualizaed linux domUs without problems.

The configuration information is posted below. Any help would be gladly 
appreciated.
regards,

jacek

dom0 is debian lenny

The config file is (i've tried it both with ioemu, and without ioemu in 
the "disk =" line) :
import os, re
arch = os.uname()[4]
arch_libdir = 'lib64';
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 384
name = "xp1"
vif = [ 'type=ioemu, bridge=xenbr0' ]
#disk = [ 'file:/testvirt/xp1/hda.img,ioemu:hda,w', 
'file:/testvirt/iso/xpsp3pl.iso,ioemu:hdc:cdrom,r' ]
disk = [ 'file:/testvirt/xp1/hda.img,hda,w', 
'file:/testvirt/iso/xpsp3pl.iso,hdc:cdrom,r' ]
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
boot="d"
sdl=0
vnc=1
vnclisten="0.0.0.0"
vncdisplay=10
vncunused=1

It doesn't say svm in flags: when booted into dom0, but when i boot 2.6.25 (no 
xen) it does. xm dmesg says "HVM: SVM enabled" so i assume that this is not a 
bug.
