Hi Friend,

I have installed Liberty on 3 node Ubuntu. After configuration of Compute node I could see hypervisor list is empty..

Please find the below details as per my observation and suggest me for any possible solution on this.

nova hypervisor-list
+----+---------------------+-------+--------+
| ID | Hypervisor hostname | State | Status |

Configuration file as per below reference link:

In compute node the loaded the KVM kernel module and noticed the parameter has configured properly
