Yep, the backported commit introduces the new imports that the original patch didn't have. Sounds like a bad rebase: diff --git a/nova/network/neutronv2/api.py b/nova/network/neutronv2/api.py index 1f96360..7e04714 100644 --- a/nova/network/neutronv2/api.py +++ b/nova/network/neutronv2/api.py @@ -39,6 +39,9 @@ from nova.network import base_api from nova.network import model as network_model from nova.network.neutronv2 import constants from nova import objects +from nova.openstack.common import excutils +from nova.openstack.common import log as logging +from nova.openstack.common import uuidutils
I see that excutils is no longer in nova.openstack.common and it is in oslo_utils. I also have a rhel-osp-director 7 overcloud and I was able to successfully boot an instance, which means I got past installing the undercloud and successfully deployed the overcloud as well.
