Default full windows virtualisation problem on Ubuntu 8.04 and XEN 3.1

Hi,
I try to setup a fully virtualized Windows XP guest with a Ubuntu
Hardy (8.04) dom0.
The domU launching (with "xm create /etc/xen/winXP.cfg") is without
any error message.
But when I try to connect to it with vncviewer connection is
established but I am not seeing vnc window.
When I comment "disk" line in /etc/xen/winXP.cfg configuration file
vnc I can see vnc window and booting bios messages.
Linux paravirtualisation is working file. I have tried xen on debian
etch and on the same computer and works fine.
(I have eaven tried install ubuntu-xen-server and xen-ioemu-3.1 but
xen python libs not maching - not allow me to run anything at the end)
If you have any suggestion would be welcome...

Installed debs:
xen-ioemu-3.1, libasound2-plugins, libvncserver0-dbg, linux-image-xen,
xen-tools, xen-utils-3.1, bridge-utils


root@ubuntu:/etc# uname -a

dd if=/dev/cdrom of=windowsXP.iso
dd if=/dev/zero of=xenwinXP.img bs=1024k seek=10000 count=0

Uncomment line in /etc/xen/xend-config.sxp:
(network-script network-bridge)

Changed line in /etc/modules to:
loop max_loop=64

Reboot OS
