[devstack][tempest][neutron][ironic] Trouble debugging networking issues with devstack/lib/tempest

Hey all,

We've been having networking issues with our ironic CI job and I'm a bit 
blocked. Included is a sample run of the job failing [0]. Our job 
creates a single flat public network at [1]. Everything goes fine until 
we hit 'lib/tempest'. The job fails trying to create a network [2].

At first I thought this could be because we configure a single physnet 
which is used by the 'public' network, however I've tried jumping on the 
node, deleting the 'public' network and creating the network mentioned 
in lib/tempest and it still fails with:

Error while executing command: HttpException: 503, Unable to create the network. No tenant network is available for allocation.

Does anyone have any insight into what we're not configuring properly? 
Any help would be greatly appreciated!
