Hi, I am reading frontend and backend block drivers. I find the frontend and 
the backend are matched magicly by xend. Is there any way for the frontend to 
choose a backend by itself? I am trying to provide a new pair of frontend and 
backend drivers. How can I let xend know they should match each other? I can 
assign them a different pair of IDs in domain_controller.h, of course. 

Another question is about the function virt_to_machine. Does it convert linear 
address to machine address? Is the machine address here the same as physical 
memory address? If not, when a page is used as a shared ring, why the machine 
address is sent, instead of the physical address?
