Description of problem: When you setting user_total_quota size is in bytes, unit should be in KB\MB\GB Version-Release number of selected component (if applicable): RHEL 6.5 python-glanceclient-0.12.0-1.el6ost.noarch openstack-glance-2013.2-5.el6ost.noarch python-glance-2013.2-5.el6ost.noarch
This should be an RFE for supporting human readable sizes. The stored value should remain as is, but user should be able to work with numbers such as 100M 3G etc.
