Public bug reported:

The compute API 2.37 microversion allows the user to specify
networks='auto' to auto-create a network for the server if an existing
network is not available for the tenant.

I setup a current devstack for master (rocky):

stack@multiattach:~/devstack$ git log -1
commit 730ce45466a903c639554b2e70f6e40a02e9e29d


There are networks available to the tenant:

stack@multiattach:~/devstack$ openstack network list

+--------------------------------------+---------+----------------------------------------------------------------------------+


But for some reason when I was creating the server, the networks panel didn't show any available networks (see attached screenshot).

That seems like a bug in itself, but the purpose of this bug, is that
let's assume the tenant didn't have any available networks - if compute
API 2.37 is available, horizon *could* present some kind of 'auto'
option for the user to tell nova to auto-allocate a network (via
neutron).

So I guess this is a feature request.
