Hi Fuel Dev,

We are facing issue in listing hypervisor-list in Controller node. Kindly let us know why nova hypervisor-list does not list compute node. Also, it would be great if you share us the sample nova-compute.conf file. Details are provided below -

Controller Node : 10.24.41.3:
root@node-6:~# nova hypervisor-list
+----+---------------------+
| ID | Hypervisor hostname |
+----+---------------------+
+----+---------------------+

Since nova hypervisor-list is empty, we have added below code in Compute Node-10.24.41.2.
/etc/nova/nova-compute.conf file
