Vagrant is a tool for building and distributing development environments.

VagrantPlugins::ProviderVirtualBox::Config#destroy_unused_network_interfaces

If true, unused network interfaces will automatically be deleted.
This defaults to false because the detection does not work across
multiple users, and because on Windows this operation requires
administrative privileges.
