Bug Description
- [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.
