Q1: how to know use config file(Vagrantfile)
A1: you must run "vagrant up" with Vagrantfile directory.

$ vagrant up onap

$ vagrant destroy -f onap

$ vagrant status
Current machine states:

control                   running (virtualbox)
compute-1                 running (virtualbox)
onap                      running (virtualbox)

This environment represents multiple VMs. The VMs are all listed
above with their current state. For more information about a specific
VM, run `vagrant status NAME`.
