Please note that an additional configuration step is required for the configuration of data interfaces with the introduction of https://storyboard.openstack.org/#!/story/2004455 "Move neutron provider network modelling to system configuration" Notably, the following system command Is required prior sysinv to referencing the datanetwork (formerly known as ' providernetwork'): system datanetwork-add In the following example, The datanetwork-add needs to be done prior to assigning the datanetwork (PHYSNET0) to the interface: # configure the datanetworks in sysinv, prior to referencing it in the system host-if-modify/host-if-add command system datanetwork-add ${PHYSNET0} vlan system host-if-modify -m 1500 -n data0 -d ${PHYSNET0} -c data ${COMPUTE} ${DATA0IFUUID} Notes: * The system host-if-modify '-p' flag will still work but is being deprecated in favor of '-d' for datanetwork * If the datanetwork-add step is skipped, the following Client exception will be raised: "DataNetwork physnet0 could not be found.") 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. See summary of other datanetwork commands in the story reference and associated Gerrit reviews.
