That gives you something like

xl block-list 6
Vdev  BE  handle state evt-ch ring-ref BE-path                       
768   0   6      4     16     8        /local/domain/0/backend/vbd/6/768
832   0   6      4     17     9        /local/domain/0/backend/vbd/6/832

How do map those BE-paths to a /dev/disk or /dev/mapper path that I can use in 
an lvcreate command at the Dom0?

Ok, so nothing in the xen info has 'knowledge' about thar?  I have to test & 
see, once I have the disk path?

 I want to tar.gz the result.  IIUC, I need the contents for that, right?
