Can anyone help me with the setup of Tap as a Service on Openstack with Juju and Maas?

I've seen tutorials for installing it on DevStack but nothing for large scale setups.

So far I've tried doing a similar process to this:

basically install the apt on the neutron_api lxd and on the compute nodes, with configurations that are done in the above tutorial. Sounds simple enough.

But the tap_services and tap_flows stay in Down state.

Any ideas??? Also I'm open to another way to do port mirroring if this doesn't work.
