When I use the UI to provision a primary UDN into a namespace, I get the following error (after indicating which project I want the UDN in, and which subnet it'll output the following error:

"""
Admission Webhook Warning
UserDefinedNetwork primary-udn violates policy 299 - "unknown field \"spec.layer2.ipamLifecycle\"
"""

4.99

Always

1. create a project
2. create a UDN in said project; define a subnet
3. watch error

The UDN is created, but the ipam.lifecycle attribute is *not* set to persistent, which for virtualization means you'll have a useless network.

The UDN must be created with ipam.lifecycle set to Persistent for the VMs to have stable IPs across live-migration and restart / stop / start.
