We got the following feedback on the Configuring the network for the RHOSO deployment chapter of the 18.0 adoption guide:

• Section 1.7 describes creating the CRs, but doesn't mention applying them. They MUST be applied in order for the steps in section 3 to succeed.
• I believe that chapter 1.7 should also include configuration of the L2 Advertisement CR (as per step 6 in https://docs.redhat.com/en/documentation/red_hat_openstack_services_on_openshift/18.0/html-single/deploying_red_hat_openstack_services_on_openshift/index#proc_preparing-RHOCP-for-RHOSO-network-VIPs_preparing_networks)
• Section 1.7.3.1  NodeNetworkConfigurationPolicy CR is syntactically incorrect:
  • * two different API versions ("v1" and "nmstate.io/v1")
  • * kind needs to be at top level
  • * items isn't needed
