[Bug 1671927] [NEW] init local crash - unknown subnet type 'loopback'

 

Public bug reported:

cloud-init-0.7.8-5.fc25.noarch on Fedora 25
Data source: ConfigDrive
Cloud provider: Openstack

Local init ($ cloud-init init -l) crashes with error [Unknown subnet
type 'loopback' found for interface 'lo'].  Stack trace attached.

I have a config drive w/ Ubuntu-style interface file at
sr0/openstack/content/0000, and network_data.json at
sr0/openstack/latest/.  Only 0000 defines the loopback device.
Screenshots of these files are at http://imgur.com/a/qEElh.

Expected outcome is to render ifcfg-eth0 in /etc/sysconfig/network-
scripts, but leave ifcfg-lo in that directory untouched as per previous
versions, for instance cloud-init-0.7.6-5.20140218bzr1060.fc23.noarch on
Fedora 23.
