Install and configure a compute node

yum install -y openstack-nova-compute

vim /etc/nova/nova.conf

[DEFAULT]...enabled_apis = osapi_compute,metadata

[DEFAULT]...transport_url = rabbit://openstack:[email protected]

[DEFAULT]...auth_strategy = keystone[keystone_authtoken]...auth_uri = http://controller:5000auth_url = http://controller:35357memcached_servers = controller:11211auth_type = passwordproject_domain_name = Defaultuser_domain_name = Defaultproject_name = serviceusername = novapassword = 123456

[DEFAULT]...my_ip = 192.168.1.201

[DEFAULT]...use_neutron = Truefirewall_driver = nova.virt.firewall.NoopFirewallDriver

[vnc]...enabled = Truevncserver_listen = 0.0.0.0vncserver_proxyclient_address = $my_ipnovncproxy_base_url = http://controller:6080/vnc_auto.html

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

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

Finalize installation

egrep -c ‘(vmx|svm)‘ /proc/cpuinfo

If this command returns a value of one or greater, your compute node supports hardware acceleration which typically requires no additional configuration.

If this command returns a value of zero, your compute node does not support hardware acceleration and you must configure libvirt to use QEMU instead of KVM.

vim /etc/nova/nova.conf

[libvirt]...virt_type = qemu

# systemctl enable libvirtd.service openstack-nova-compute.service# systemctl start libvirtd.service openstack-nova-compute.service

Perform these commands on the controller node.

. admin-openrc
