Found this while troubleshooting, seems pertinent -> https://ask.openstack.org/en/question/30413/error-neutronagentlinuxdhcp-an-interface-driver-must-be-specified/

[james beedy (jamesbeedy)]

From hook debugging, I feel like neutron-openvswitch is looking for a public network space? Should it have one?

[James Page (james-page)]

No - it should only have a data binding - this problem looks specific to the DVR path - which is using resolve_address (slightly unexpected as that's for API services to use).

[james beedy (jamesbeedy)]

This bug only exists when 'enable-dvr' is set to 'true'.

[james beedy (jamesbeedy)]

@jamespage, replacing resolve_address with `get_host_ip(unit_get('private-address'))` worked as a quick fix for me. Not sure if thats what you are going for though...

Fix proposed to branch: master

[James Page (james-page)]

Pushed proposed fix to master branch to the charm store for general testing:

  cs:~james-page/xenial/neutron-openvswitch-bug1580271

Once this lands into master, we'll sort out a backport to stable/16.04 as well.

    Drop use of resolve_address

    The shared secret context makes use of 'resolve_address' to
    resolve the local_ip address of the unit; the resulting
    value is not actually used in the metadata_agent.ini template
    and breaks under Juju 2.0, where resolve_address attempts
    to use network-get to resolve the public endpoint of the
    service using extra bindings (which are not relevant for this
    charm).

    Drop use of resolve address and tidy templates; the default
    127.0.0.1 address is fine for accessing the Nova Metadata
    service from the Neutron Metadata agent proxy.
