This is a nova bug introduced /w
https://review.openstack.org/#/c/102649/ that prevents instances from
booting unless their network has an ipv4 subnet. Instances on a network
that only have a single ipv6 subnet will fail on this AttributeError
** Summary changed:
- appliance fails to spawn, AttributeError: 'NoneType' object has no attribute
'get'
+ boot fails on network /w only an ipv6 subnet, AttributeError: 'NoneType'
object has no attribute 'get'
** Also affects: nova
Importance: Undecided
Status: New
** Changed in: akanda
Status: New => Invalid
