There might not be a right answer but 1 is definitely a wrong answer.

Changing /etc/libvirt/storage/default.xml to point to a directory in a 
separate partition with lost of free space was easy.  However, when I tried to 
create a new guest using virt-manager and the creation "wizard", for the disk 
image, it still showed the free space available in the root partition (8GB) 
rather than that of the other partition (120GB),

So I resorted to 2 which appears to work OK.

My current thinking is to use option 3 ultimately.  That way, I can get things 
configured when I install a new system.

If you believe that option 1 should work then there appears to be a bug.  
Please clarify.  If there is a bug, I will bugzilla it.
