This bug was initially created as a copy of Bug #1761903 I am copying this bug because: As we haven't had capacity to QE this, need a release note for tech preview in 17.0 ga. Description of problem: Routed network support was originally added upstream in newton (osp 10) https://specs.openstack.org/openstack/nova-specs/specs/newton/implemented/neutron-routed-networks.html customer have requestied that this feature be supproted in OSP and work is underway to enable it https://bugzilla.redhat.com/show_bug.cgi?id=1671811 https://bugzilla.redhat.com/show_bug.cgi?id=1721113 the current implemeantion of routed network relys on the use of ip_allocation=defer which requried the ip to be assigned only after a host is selected because the nova schduler and placment is not aware of the subnet affinity between netwrok segment and compute host. work is underway to report netwrok segments to palcement as aggregtes but to complete the integration work is need in nova to be able to include segment infomraiton in the placmenet query such that we can guarentee that the the select host will be conented to the correct neutron segment. this will allow better tacking of ip aviablity and ip locality enabling more accurate scheduling and will enable nova and placmenet to be aware of ip subnet restriction wehn migrating, resizing or unshelveing instances. To achive this nova need to be enhanced to schdule based on routed networks. This is an important usecase for edge deployments. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
The release notes automation will pick up BZs with the right flags even if they're closed. With the doc text done and requires_doc_text set to +, we can close this.
