Can you share the ouput of:

tree /dev/disk

On the guest?

And the output of

pvscan --cache
lvs -o vg_name,name,tags

On the host?

On the guest, the the disk serial number should be the first 20
characters of the disk
uuid (I think it is the image uuid in vdsm terms, or disk uuid in engine terms).

The image uuid should appear in a lv tag on the host, and the prefix
of this uuid should
be found on the guest.

Can you describe why do you need this information?
