Comment 2 for bug 1839715

gnuoy,

Have you set 'host' config option in /etc/nova/nova-cpu.conf on the compute nodes?

On my compute node machine:

$hostname
compute_01.xyz

$openstack compute service list --service nova-compute
+----+--------------+--------------------+------+---------+-------+----------------------------+
| ID | Binary | Host | Zone | Status | State | Updated At |
+----+--------------+--------------------+------+---------+-------+----------------------------+
| 12 | nova-compute | compute_01.xyz | nova | enabled | up | 2019-11-12T08:09:55.000000 |
+----+--------------+--------------------+------+---------+-------+----------------------------+

$openstack hypervisor list

It returns empty list. I can see below error in n-api.log.
