Hey Brian,

Thanks! The job had embarrassingly been broken on an issue with 
lib/ironic for quite some time so it's hard to say when the networking 
issues arose. The only thing that's changed between the last successful 
run and now (on our side), is that we cherry pick a patch into devstack 
[0]. Highly doubt it's related but figured I'd mention it.

I'll investigate properly setting the tenant network types. Thank you 
for the lead, much appreciated!

Thanks,
