Hi, all

Multiple cells (Nova-Cells-v2) is supported in Pike release.
It is necessary to confirm that existing APIs work appropriately in the 
multiple cells environment.
We will post multiple patches, so I created BluePrint[1] to make it easier to 
keep track of those patches.
Please check the contents and approve it.

We don't really need a blueprint for this work. It would be good to know what gaps in existing testing you think exist. And where do you plan on implementing these tests? In the nova/tests/functional tree or somewhere else? We already have a lot of tests which are using a CellDatabase fixture which allow us to create multiple cell mappings for tests in the API.

If you're considering Tempest, tests there wouldn't really be appropriate because to the end user of the API, they should have no idea if they are talking to a cloud with multiple cells or not, since it's really a deployment issue.

What we don't have today in our CI testing, and that we need someone to work on, is running a devstack multi-node setup with at least two cells. This likely requires some work in the devstack-gate repo to configure devstack per node to tell it which cell it is.

I encourage you to bring this up in a weekly cells v2 meeting for further discussion:
