Vagrant is a tool for building and managing virtual machine environments in a single workflow. It uses a concept called providers to manage the virtual environments. Providers are responsible for creating and managing the virtual machines. Some common providers include VirtualBox, VMware, and AWS.
* Providers: Vagrant relies on external hypervisors (providers) to run virtual machines. For example, VirtualBox can be used as a provider, and Vagrant will interact with VirtualBox to create, configure, and manage the virtual machines.
* A: There is no vagrant-specific hypervisor called VagrantVM.
* B: Vagrant itself does not need to run within a virtual machine not controlled by Vagrant.
* C: Vagrant does not ship with an embedded version of VirtualBox; it relies on installed providers.
* E: Vagrant does provide mechanisms to run virtual machines using providers.
