Explanation OpenStack, trace server create call:
- keystone, service catalog, token
- nova api, nova scheduler, nova conductor
	- doesnt know individual, whole schedules server
	- nova libvirt talks libvirt, creates vm
	- host aggregates mentioned + flavor extra specs
		- vm calls metadata @ 169.169... mentioned
			- cloud-init
- nova wants port -> rabbit -> neutron
- neutron api, ovn controller
	- ovn northd, nb, sb
	- neutron ml2 plugin translates neutron to ovn nb
