So, there are a few things which happen here. VM provisioning is handled by the compute driver (checkout run_instance in nova/compute/manager.py). Scheduling however is handled by the scheduler, which has a plugin system (checkout nova/scheduler/*).
Also, you'd be better off browing git for the source code ( http://github.com/openstack/nova.git) instead of the system installed files.
