Hi, I was following this install guide to install OpenStack with RDO: http://openstack.redhat.com/Quickstart

After install and OpenStack start, every time I boot a new instance, there will be a new nova-compute start up, after I create two instance, there are three nova-compute, do you know why the instance create caused new nova-compute start?
