So sorry, I meant of course to write that the utility is *lvmthin*
(_not_ thinlvm).

As of around CentOS 6.5 (and for sure in RHEL 6.4) that there is a
thinlvm *lvmthin* utility that seems to take care of supporting
thinly-provisioned LVM volumes. There is an associated snapshot design
based on LVM thin provisioning that even supports the ability to do
snapshots of snapshots, etc. down the chain.
Unfortunately, from a cursory look, it doesn't look like a back port
to CentOS 5 would be that easy or even possible, but that it is
integrated into both CentOS 6 and CentOS 7 gives some hope for a
possibly standardized support of it in a future XenServer release,
doesn't it? The other big question would be how readily something like
this could be integrated into XenServer.
