Hi, Porting OpenStack applications during the Liberty Cycle was discussed last days in the thread "[oslo] eventlet 0.17.3 is now fully Python 3 compatible". I wrote a spec to port Nova to Python 3: https://review.openstack.org/#/c/176868/ I mentioned the 2 other Python 3 specs for Neutron and Heat. You can reply to this email, or comment the review, if you want to discuss Python 3 in Nova, or if you have any question related to Python 3. See also the Python 3 wiki page: https://wiki.openstack.org/wiki/Python3 Thanks, Victor
