Avoiding IP Address allocation.


I do not want quantum to allocate addresses for a particular network.  From what I read,  I should just do the "quantum net-create" without the "quantum subnet-create", but when I do I get the following error in compute.log:

I do not get the error when I do the "quantum subnet-create" with the "quantum subnet-create" and just ignore the allocation.  It seems like either I am doing something wrong or there is a better way.
