Austin, 1) When we move to Stein, the 'neutron providernet-create', which was an stx extension. will no longer be supported. As noted in the Story, the host to physical network bindings will no longer be in neutron and thus must now be modelled in sysinv so that the datanetworks (providernetworks) can be mapped to host data interfaces. Furthermore, references to datanetworks in the platform horizon is being updated to reference sysinv rather than neutron; as neutron is being containerized. 2) The commit referenced is: http://stash.wrs.com/projects/CGCS/repos/github.com.openstack.neutron/commit...

I have some questions: 1) when I tried this one, it seems 'neutron providernet-create' is still needed before 'system datanetwork-add' , what's benefit for introducing "system datanetwork-add" command ? 2) in https://storyboard.openstack.org/#!/story/2004455 story , there mentioned The related stx-neutron feature commit is the following: 021ae1ac80ca7cbde9903c83b540ca775b05a94f But I cannot find this commit in code base. Thanks. BR Austin Sun.

Thanks, John Details: This is in preparation for upstream neutron which is not planned to support providernetwork host interface-physical data network binding. Note also Horizon stx-gui Data Networks panels are under development and now refers to provisioning of data networks in sysinv; and not providernetworks in neutron.
