"[...] how does running a virtual machine that pretends to be a Linux/x64 box... on top of a real Linux/x64 box saves anybody at least some time?"

To borrow someone else's words: https://blog.engineyard.com/2014/pets-vs-cattle

Or, in summary, it's a heck of a lot easier to instantiate a new instance of a machine from a snapshot than instantiate a new machine from a set of directions and some auto-config scripts.

I agree standard images are much easier to set up than a hand configured system. That does not mean said image should run on top of an emulator.

I see some value in having a running system right now, instead of waiting for a long latency while the image is downloaded to real hardware... at least in some situations. However, is taking a permanent performance degradation of an order of magnitude worth that advantage?
