Hi,

libvirt doesn't know thin pools.

But if you create a logical pool in libvirt using a certain volume group, the
thin volumes created in this volume group should be visible to libvirt*.

* I haven't actually tested it. Looking at the code, we only skip over the
logical volumes of type 't', which is the volume containing the thin pool, but
the thin volumes ('V' in lvs output) are not skipped.
