The OpenStack Compute service provides the cloud environment with the ability to manage the scheduling, creation and deletion of virtual machines (instances). Install the OpenStack Compute packages: # apt-get install nova-api nova-cert nova-common nova-conductor \ nova-scheduler python-nova python-novaclient nova-consoleauth novnc \ nova-novncproxy # yum install openstack-nova-api openstack-nova-scheduler \ openstack-nova-cert openstack-nova-console openstack-nova-doc \ genisoimage openstack-dashboard openstack-nova-novncproxy \ openstack-nova-conductor novnc # zypper install openstack-nova-api openstack-nova-scheduler \ openstack-nova-cert openstack-nova-conductor openstack-nova-console \ openstack-nova-consoleauth openstack-nova-doc \ openstack-nova-novncproxy Configure OpenStack Compute: Edit /etc/nova/api-paste.ini: admin_tenant_name = service admin_user = nova admin_password = password [filter:authtoken] paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory service_protocol = http service_host = 127.0.0.1 service_port = 5000 admin_tenant_name = service admin_user = nova admin_password = password # Workaround for https://bugs.launchpad.net/nova/+bug/1154809 auth_version = v2.0 admin_tenant_name = service admin_user = nova admin_password = password Add the following to the /etc/nova/nova.conf file. This file is the main configuration file of OpenStack Compute. There is a large amount of configuration options that can go in this file. This guide illustrates the minimum needed for a simple environment. Note that the nova.conf file supplied by your distribution has some options already set. Leave them as-is.
