You can only really have one domain running the actual driver.  The best 
strategy would therefore be to keep as much IO processing as possible in 
other domains (preferably in the guests themselves).

With user-accessible hardware (e.g. Infiniband), unprivileged guests will be 
able to access their hardware directly using their own CPU time (and get 
better performance in the process).  Of course Infiniband is rather expensive 
so this won't be the most common way of doing stuff for some time (if at 
all).

Cheers,
Mark
