Here we go :


#!/bin/bash

#created Thursday April 26
#following Richard W.M.Jones <rjones at redhat.com> advices and script
#this script can be changed according your own need. This one will
#install a debian VM called daffodil on a LVM partition, with 2 CPU, 
8192 RAM

# Script used to install VMs.
# You have to lvcreate the disk first!
# lvcreate -L sizeG -n $name vg_data

set -e

name=daffodil
cpus="--cpu=host --vcpus=2"
disk="--disk path=/dev/vg0/lv_daffodil"
location="--cdrom 
/var/lib/libvirt/images/isofiles/debian-6.0.4-amd64-netinst.iso
type="--os-type=linux"
variant="--os-variant=debiansqueeze"
graphics="--graphics spice"
extra="bus=virtio"
network="--network bridge=br0"


virt-install -n $name -r 8192 \
   $cpus $type $variant $disk $location $graphics $extra $network



Hope everything is correctly set up and it can help other users. I 
realised KVM is not so straightforward and could be very different 
depending on your source.
