You can certainly use devstack with multiple nodes: http://docs.openstack.org/developer/devstack/guides/multinode-lab.html With respect to controlling which compute node gets a given instance, I think you will need to mess with the Nova Scheduler (filters): http://docs.openstack.org/trunk/config-reference/content/section_compute-scheduler.html Regards Mark On 23/02/15 23:18, Claudio Pupparo wrote: > Hi, > > My master's thesis is about VM consolidation in OpenStack.
