Most paravirtual devices use atomic operations (or even just raw memory 
accesses and memory barriers), which don't need any special 
infrastructure.  This effectively makes them message-passing protocols 
rather than shared memory protocol.  I can't see offhand why sharing 
data structures would bring a great improvement, but maybe I'm tied to 
the old way of thinking.
