I have installed Controller Node on one Physical server and Compute Node on another Physical server. In Services table of Nova database in controller node it is showing the compute node. But it's not appearing in the Hypervisiors in Horizon. Can you let me know how make it appear? And how to use compute node?

Run the command nova service-list. Do you see compute ? If not ensure that compute service is running in the compute box. Hope you have completed all the necessary installation and configuration by referring the official documenation

Hi, yes it is appearing on running that command. I had created around 10 instances of Ubuntu and none of them were scheduled on compute node.

Are they going to error state ? What is the output of 'nova list' ? What do you mean by none of them are scheduled on computenode ? Instances have to either get into active state or some error state. They just can't disappear.

Check that the Compute is enabled and has a smiley reported in `nova-manage service list` output. Also check the nova scheduler logs while spawning instance.

@umesh-gurjar in `nova-manage service list` output on controller node is showing all the services enabled with a smiley running on controller and it's showing nova-network enabled with smiley running on compute node but it's not showing the compute service running on compute node, that's what i'm not able to understand I have gone through whole log of installation of compute node but no error is thr. Only one thing which i feel is wrong is that nove_compute.conf file is not created in my compute node after the installation which should have been thr after the installation. And i don't know how to get that file thr.. i created it but i'm not able to restart nova services.
