[Bug 1757996] Re: "nova list command error : <class 'sqlalchemy.exc.ProgrammingError'> (HTTP 500) (Request-ID: req-50de465b-0005-4dd1-a190-514491e3fd33)

 

The error in the nova-api logs is pretty clear:

Table 'nova_cell0.instances' doesn't exist

You either haven't setup the nova_cell0 database or cell mapping, or
haven't run the schema migration on that database. See:

https://docs.openstack.org/nova/latest/user/cells.html#setup-of-cells-v2
