Then you want to go with filesystems on Dom0 partitions (LVM volumes just 
being partitions in this regard). Install your "template machine" to a 
file, tweak everything you want, create a LV with filesystem, then rsync 
(with --numeric-ids) the contents of that VM (while it is running) to it, 
adjust files (grub.conf, fstab maybe others) at the new location (you can 
mount it now without problems) and you've got your new VM template ready. 
When you want to create new VMs, create new LV, create fs, tunefs and then 
copy over the content from the template and adjust it. Template VM is 
offline all the time and only needs to be started in case you want to 
update it or change something.
