After running discover host command also not able to populate the compute node data into Resource_providers table.
The cell mapping table ahs cello and Null not cell0, post updating cell1 also -nothing resolved.
su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
nova-manage cell_v2 discover_hosts

There is a section on multinode setup in the devstack repo, doc/source/guides/multinode-lab.rst, that I think covers the issue you're seeing. Assuming your compute node shows up in 'nova service-list' output, you need to run ./tools/discover_hosts.sh to have a cell mapping added for the node.
