Open Stack

I'm familiarizing myself with the nova code and trying to reconcile that 
while there is dynamic class based loading in ComputeManager using 
import_utils in __init__() there is also a defaulting to the 
nova.virt.connection.get_connection function.

That's actually got a big if / else statement of string literals of 
known virt drivers, and then loads specific virt drivers from there.

Is there a reason for both approaches? Can we refactor to a point where 
we don't need need of a common file with driver specific imports and 
string literals? Is there a reason not to?

Thanks,

	-Sean
