Looks good. Two small nits:

This check should be 'if len(networks) > nnics' and then warn that the
last len(networks) - nnics network specs will be ignored.

It would be clearer to write these two as

        if macs is None:
        	macs = []
        elif type(macs) != list
        	macs = [ macs ]
        
same for networks
