It's probably also worth thinking about what happens when evacuating a 
sever from a host with one of these and/or deleting a server when the 
compute service on which it was running is down. Upon restart of the 
compute service we'll need to detect the guest is gone and cleanup the 
previously allocated devices somehow (I think this has been a problem 
for PCI device allocations in the past as well).
