You can use the 'location' field in the VDI to contain your 32 bit id - then 
the uuid is irrelevant. I'd like to move more of the storage backends in this 
direction - currently I believe only the ISO SR does it this way.

Unfortunately this isn't possible at the moment. What you could do is pick the 
name up on a subsequent scan. This is ugly, I know, and might not even work if 
you need the name at VDI create time, but it's all we've got at the moment. 
This is on my list of things to fix about the SMAPI.
