This example is based on the environment like follows.
If you'd like to install Nova Compute on another Host, refer to here.

        eth0|10.0.0.30 
+-----------+-----------+
|   [ dlp.srv.world ]   |
|     (Control Node)    |
|                       |
|  MariaDB    RabbitMQ  |
|  Memcached  Nginx     |
|  Keystone   httpd     |
|  Glance     Nova API  |
|  Nova Compute         |
+-----------------------+

[1]	Install KVM HyperVisor on Compute Host, refer to here. It does not need to set Bridge networking on the section [2] of the link.
[2]	Install Nova Compute.

root@dlp ~(keystone)#

apt -y install nova-compute nova-compute-kvm

[3]	In addition to basic settings of Nova, add following settings.

root@dlp ~(keystone)#

vi /etc/nova/nova.conf

# add into the [vnc] section
# IP address compute instances listen
[vnc]
enabled = True
server_listen = 10.0.0.30
server_proxyclient_address = 10.0.0.30
novncproxy_host = 127.0.0.1
novncproxy_port = 6080
novncproxy_base_url = https://dlp.srv.world:6080/vnc_auto.html

[4]	Start Nova Compute service.

root@dlp ~(keystone)#

systemctl restart nova-compute

# discover Compute Node

root@dlp ~(keystone)#

su -s /bin/bash nova -c "nova-manage cell_v2 discover_hosts"

# show status

root@dlp ~(keystone)#
