	hello Roger.  Again, thank you for the hints.  
In addition to the xvda syntax working, one can also use the hex values for the device numbers,
separated by 16, allowing one to use absolute numbers, rather than remembering letter to number
mappings.  The following syntax, for example, also works.
Note this results in the same probe messages as xvda and xvdb.


disk = [ 
'file:/var/xen/nfbcal/fbsd_dev/disk0,0xca00,rw',
'file:/var/xen/nfbcal/fbsd_dev/disk1,0xca10,rw'
 ]
