Having started using Vagrant a little while ago with VMware, and finding it a bit annoying that they were charging for a licence for the VMware plugin for Vagrant, I was pleasantly surprised to find that they've recently open-sourced it and removed the need to buy a licence.
Relevant links where I noticed this / it's documented:
* [VMware Provider | Vagrant by HashiCorp (vagrantup.com)](https://www.vagrantup.com/docs/providers/vmware)
* [Frequently Asked Questions - VMware Provider | Vagrant by HashiCorp (vagrantup.com)](https://www.vagrantup.com/docs/providers/vmware/faq)
This is really good news - since most of my peers are already using VMware, this removes the stumbling block to adoption so I hope to see lots more Vagrant use popping up in my organisation soon.
