Comment 7 for bug 1858416

Hello Frode !

It would appear there might be a mismatch indeed.
For our setup we use MAAS to PXE boot and commission our environment. This happens on a 10.80.0.0/16 interface. We expect OpenStack to be deployed on interface bond0.30 with a range 172.30.0.0/16.
In Juju all spaces are bind to the 172.30.0.0/16 subnet.

Thank you for you support on this.
Feel free to ask for any other details.
