Now that we have a machine for running OpenStack, we can install the appropriate packages for running OpenStack Compute, which will allow us to spawn its own virtual machine instances.
To do this, we will create a machine that runs all the appropriate services for running OpenStack Nova. The services are as follows:
nova-compute: The main package for running the virtual machine instances
nova-scheduler: The scheduler picks the server for fulfilling the request to run the instance
nova-api: Service for making requests to OpenStack to operate the services within it; for example, you make a call to this service to start up a new Nova instance
nova-network: Network service that controls DHCP, DNS, and Routing
