Was discussing this one with Neil on openstack-dev here: http://lists.openstack.org/pipermail/openstack-dev/2016-December/109080.html Which would seem to have been filed as: https://bugs.launchpad.net/nova/+bug/1649527 Thanks, Steve > We ended up adding an additional yum repo definition pointing to > the older 7.2 repo and doing a yum history rollback and we’ve stopped > pointing to the 7.3 repo altogether.
