So, thank you very much for your detailed explanation. Would
an implementaion change on "dmsetup" also solve the "Limitation of 32 snapshots" ?

Yes - that is a in-use per-machine limitation, and you'd only
be using one snapshot on each machine.

Do RH or the community want in integrate the changes in dmsetup - is there maybe a timeline for this ? My task is to take n (e.g. n=5) identical snapshot(snap1-5.LV) from a xen-image (base.LV) and run
5 Xen-VM's (based on snap1-5.LV) on 5 different XEN-Server (phy.HW).

If this could not done with CLVM2, i have to change the concept to use GFS/OCFS2.
