Public bug reported:
- [X] This doc is inaccurate in this way: Documentation suggests nova v2 cells do not make 'upcalls' but they do when talking to the placement api. - [ ] This is a doc addition request. - [ ] I have a fix to the document that I can paste below including example: input and output. It is important to note that services in the lower cell boxes only have the ability to call back to the placement API and no other API-layer services via RPC, nor do they have access to the API database for global visibility of resources across the cloud. This is intentional and provides security and failure domain isolation benefits, but also has impacts on somethings that would otherwise require this any-to-any communication style. Check the release notes for the version of Nova you are using for the most up-to-date information about any caveats that may be present due to this limitation. ----------------------------------- Release: 17.0.0.0b3.dev323 on 2018-01-09 21:52 SHA: 90a92d33edaea2b7411a5fd528f3159a486e1fd0 Source: https://git.openstack.org/cgit/openstack/nova/tree/doc/source/user/cellsv2-layout.rst URL: https://docs.openstack.org/nova/latest/user/cellsv2-layout.html ** Affects: nova Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
