Bug Description
While spawning more instances then max_nbd_devices (or 16 per default) I got the error "2011-02-27 22:45:22,370 WARNING nova.virt.
". I think there sould be some logic to handle this case.

I guess the thing to do here would be to wait until an NBD device frees up
Or is this the race condition that Pádraig talks about here:
