The answer to this, and Jay's same question elsewhere in this thread, is 
likely going to need to come from danpb who I think originally added the 
serial stuff in the libvirt driver. I could not find discussions about 
why the serial was per-host rather than per-guest in the original code 
changes. So besides "this is the way it's always been" and I'm risk 
averse to backward incompatible changes, I don't have a good answer.
