There is also Vagrant which lets you specify VM specs, but also lets you install software in the VMs automatically. It also works for other VM software then just Virtualbox.

While true regarding open source vs closed course. The risks are quite large for patients. For example, a few years ago there was a company called Second Sight that made artificial eyes so blind people could partially see again. Then the company discontinued the product and now they are stuck with an unsupported surgically implanted device that they rely heavily on but can break any time. It’s pretty risky to have something implanted if you don’t know if the company will be around in a decade or so.
