Description Stephen Gordon 2015-11-13 18:52:17 UTC 
Cloned from launchpad bug 1304409.

Description:

Recently a change in the nova/network/neutronv2/api.py file is causing nova boots to fail for networks that do not have a subnet associated with them.

The following line in the api.py file is causing the issue:

            for net in nets:
                if not net.get('subnets'):
                    raise exception.NetworkRequiresSubnet(
                        network_uuid=net['id'])

This has to be fixed to allow users to do boots with networks that do not have a subnet associated with them.

The issue seems to be occuring post the commit done here:
