We use Vagrant and Virtualbox heavily when developing Puppet code. We also do provisioning of baremetal servers with Foreman. While Vagrant is a really powerful tool, it is not designed for creating VMs that boot from the network (PXE boot).

It is assumed below that there is a PXE boot server (e.g. Foreman) created into a hostonly network with Vagrant. Here’s an example script that create a VM with vboxmanage and adds it the same hostonly network interface (vboxnet15) as the PXE boot server:
