Trouble viewing Windows guest on xen

Hello,

I have xen running on Debian Etch (64-bit version) I'm running a Windows XP guest, but I haven't been able to view its desktop.

I think it has something to do with VNC.

Here's my windows guest config file (winxp.cfg):

Code:

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

kernel = '/usr/lib/xen-3.0.3-1/boot/hvmloader'
builder = 'hvm'
memory = 640
shadow_memory = 8
device_model = '/usr/' + arch_libdir + '/xen-3.0.3-1/bin/qemu-dm'

#HostName
name = "winxpVM"

#Networking
vif = [ 'type=ioemu, bridge=xenbr3' ]

#Behaviour
acpi = 1
apic = 1
stdvga=0
#boot on floppy (a), hard disk (c) or CD-ROM (d)
#default - hard disk, CD-ROM
boot='dc'
vcpus=2
sdl=0
vnc=1
vncviewer=1
serial='pty'
usbdevice='tablet'

#Disks
disk = ['file:/home/xen/windows/winxp.img,ioemu:hda,w', 'file:/home/xen/windows/winxp.iso,hdc:cdrom,r' ]

This is what happened when I started this guest:

Code:

user@vmbed:/home/xen/windows$ sudo xm list
Name                        ID Mem(MiB) VCPUs State   Time(s)
Domain-0                     0     7403     8 r-----     52.8
user@vmbed:/home/xen/windows$ sudo xm create winxp.cfg
Using config file "winxp.cfg".
VNC= 3
Started domain winxpVM
user@vmbed:/home/xen/windows$ sudo xvnc4viewer vmbed:3

winxpVM                      4      640     1 ------      0.0

What could the matter be, please?

it might be network related

I prefer use real disks instead of images:
disk=['phy:/dev/sda8,ioemu:hda,w','phy:/dev/scd0,ioemu:hdc:cdrom,r']

The other config file contains network config:

/etc/xend/xend.config

If you use bridge as your configuration suggests you should google for iptables firewall fix. I use the machine as router also and for me it was faster to use pre-configuration of network-nat:

Uncomment this part:
(network-script network-nat)
(vif-script vif-nat)

and comment out the rest. You can comment out bridge in winxp.cfg

the vnc will be accessibile on locahost:3 based on your config
