Hi Miroslav,

Compute node deployment is successful. Please find the below screenshot. “nova hypervisor-list” is empty because nova-compute.conf file is not configured automatically and only the below lines was available.

[DEFAULT]
compute_driver=libvirt.LibvirtDriver
#sql_connection=mysql://nova:gfW4v98X@192.168.0.3/nova?charset=utf8
[libvirt]
virt_type=kvm

[cid:image003.jpg@01CF8A3E.6BD636C0]


Our understanding is /etc/nova/nova-compute.conf file is required at Compute node only and not at Controller node. Compute node will use this nova-compute.conf file to intimate the neutron present in Controller node to assign IP address and so on. I have already provided the configurations/lines added in nova-compute.conf file at the below mail conversation.

Kindly let us know why the hypervisor-list is not listing the compute nodes and what are the configurations we have to make so that hypervisor-list will list the compute nodes.

Thanks and Regards,
Gandhi Rajan

Greetings Gandhi,
Have Fuel deployed your compute node successfully? It should create all the configuration files automatically.
BTW, there is no /etc/nova/nova-compute.conf in OpenStack. There is /etc/nova/nova.conf on both, controller and compute nodes.
Kind regards,
Miroslav

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<http://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.
