The responses to the Glance user survey question are in the following etherpad to make it easy to record reactions and/or suggestions for follow-up: https://etherpad.openstack.org/p/glance-user-survey-q-feb-2017 This was the question we asked: "As you're aware, the Images API v1 supplied by OpenStack Glance is currently deprecated. If you haven't yet moved to the Images API v2, what is preventing you? Please be specific." cheers, brian
