Comment 21 for bug 1196666

I consider wsun2 is correct, from code checking and shell example output result. Actually I have realized this situation before, but under my understanding in nova code, I'm sure the version number can be set as an argument in some glance related functions, but I was not checking the cinder code before. Also I will try to get the historic reason that why v2 client does not be implemented fully as v1 client in python-glanceclient.
