Hi, I am not so familiar with Xen. So I need help. I have put Xen (3.2) and XenoLinux ( into Fedora8.

After that I have  created a Debian-Etch DomU image using Xen-tools. I used the role scripts to put xdm functionality into it. With only this I tried to boot the domU image, but got some segmentation fault error while booting the domU.
Adding 131064k swap on /dev/sda1.  Priority:-1 extents:1 across:131064k
EXT3 FS on sda2, internal journal
NET: Registered protocol family 10
lo: Disabled Privacy Extensions
IPv6 over IPv4 tunneling driver
Xvnc[948]: segfault at 00000000688bc348 rip 00002b076870926b rsp 00007fff42ae33e0 error 4
Xvnc[951]: segfault at 00000000349ab348 rip 00002b60347f826b rsp 00007fff769f41a0 error 4

So following the direction in Xen-3.2.0/tools/examples/vnc/ I modified the /etc/X11/xdm/Xservers & /usr/X11R6/bin/Xvnc-xen
in domU accordingly. After booting the DomU I start a vncviewer in Dom0 to look at my DomU output. But I just get a tty type output. I do not get any X. I am attaching a screen-shot for the above process   (Screenshot-2.png)

 Even when I try starting x exclusively using startx I  get some error like 'no screens found'. I am attaching a screenshot for that also. (Screenshot-3.png).

My domU config file is as follows:
# Configuration file for the Xen instance domU.test.one, created
# by xen-tools 3.9 on Sat Nov 22 20:05:46 2008.

#  Kernel + memory size
kernel      = '/boot/vmlinuz-'
ramdisk     = '/boot/initrd-'
memory      = '128'

#  Disk device(s).
root        = '/dev/sda2 ro'
disk        = [

#  Hostname
name        = 'domU.test.one'

#  Networking
vif         = [ 'ip=,mac=00:16:3E:88:27:1E' ]

vfb = ['type=vnc']

#  Behaviour
>on_reboot   = 'restart'
on_crash    = 'restart'

extra = "xencons=xvc console=xvc console=tty"

Putting udev into DomU also did not help.

I am not sure if I am missing any step.

If some one willing to help needs some other information please let me know.
