thanks very much for your prompt reply.

regarding the first command "nova-manage cell_v2 list_hosts" the output is
the following (openstack is the host of the controller). I dont see any
other node here, even when i execute  the discover_hosts command

| Cell Name |              Cell UUID               |  Hostname |
|   cell1   | 1522c22f-64d4-4882-8ae8-ed0f9407407c | openstack |

Also this is the output from my controller when i use the command:  sudo -s
/bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova   (not sure
if this helps)
Found 2 cell mappings.
Skipping cell0 since it does not contain hosts.
Getting computes from cell 'cell1': 1522c22f-64d4-4882-8ae8-ed0f9407407c
Found 0 unmapped computes in cell: 1522c22f-64d4-4882-8ae8-ed0f9407407c

any thoughts?
