[Openstack-operators] [nova] Do you, or your users, have input on how get-me-a-network should work in Nova?

For a user that's gone and deleted their network services, then wouldn't
they perhaps be savvy enough to deploy a network/subnet pair. If they
don't want to pay for the router then this is what they'd be working
towards (by deleting their initially provisioned service). As it stands
today, if you have a single network available (regardless of upstream
router), your "nova boot" process will associate the VM to that network
For the user who is trying to do something specific, giving them an option
(opt-out if you don't want a network), actually maps the most common case
of user wants a VM to be able to get to the world to the default, and the
odd (and I haven't ever seen an actual use case where I want a VM without a
network of some nature associated to it) case of "I don't want any network"
an option by specifically calling that out on boot.
And I personally am unaware of any service provider that doesn't give you
network access by default when you stand up a project.
