Nova – Compute services on Compute nodes

Posted on October 10, 2020October 20, 2020 by sandeep

Install the packages

apt install -y nova-compute

Update following configurations in respective sections of /etc/nova/nova.conf [ Replace my_ip with the management ip of the compute node]

[DEFAULT]
transport_url = rabbit://openstack:commonpass@controller
my_ip = 10.1.1.x
use_neutron = true
firewall_driver = nova.virt.firewall.NoopFirewallDriver

[api]
auth_strategy = keystone

[keystone_authtoken]
www_authenticate_uri = http://controller:5000/
auth_url = http://controller:5000/
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = nova password = commonpass

[vnc]
enabled = true
server_listen = 0.0.0.0
server_proxyclient_address = $my_ip
novncproxy_base_url = http://controller:6080/vnc_auto.html

[glance]
api_servers = http://controller:9292

[oslo_concurrency]
lock_path = /var/lib/nova/tmp

[placement] 
region_name = RegionOne
project_domain_name = Default
project_name = service
auth_type = password
user_domain_name = Default
auth_url = http://controller:5000/v3
username = placement
password = commonpass

Since hardware acceleration was supported in my hardware did not update the following (in /etc/nova/nova-compute.conf)

[libvirt]
virt_type = qemu

Restart the Compute service

service nova-compute restart

Execute the following on controller node – add the compute node to the cell database

. admin-openrc
openstack compute service list --service nova-compute

Discover compute hosts

su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
18.04 bionic compute node compute service install nova Openstack train ubuntu
