Dom0 windows server 2003 lvm resize

I need to reduce the disk size allocated to a windows 2003 paravirtual lvm disk based vm.
Using Centos, using LVM to allocate disk to VMs (windows and linux VMs).
Windows VM is only one disk, only one ntfs partition on it.
I need to shrink ntfs partition in guest before resizing volume, but I am unable to boot from KNOPPIX live cd (iso), it hangs at "Booting kernel..."
My question: how-to successfully boot Knoppix cd (want to use it to resize windows partition).
Below is my vm config.

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"
builder='hvm'
memory = 2048   
shadow_memory = 8
name = "docushare"
vif = [ 'type=ioemu, mac=00:16:3E:56:B7:99,bridge=xenbr1,script=vif-bridge' ]
acpi = 1
apic = 1
disk = [ 'phy:/dev/raid/docusharewin,hda,w', 'file:/root/Desktop/knoppix.iso,hdc:cdrom,r'  ]
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
boot = "d"
sdl = 0
vnc = 1
vncconsole=1
serial='pty'
usbdevice='tablet'
on_poweroff='destroy'
on_reboot='restart'
on_crash='restart'

Hi!

You can try to boot from another CD to make the resize. Try "System Rescue" and run GParted. There are LVM tools on the CD as well.
