Actually, there is a generalization of this - situations where
running a VM is just an implementation detail of a container,
and hence they should be "lifecycle bound" together in
the same physical location.

So for example if you have a video transcoding service, you might
use a VM as a processing pipeline *locally*, without having to
pay the cost of sending the data to/from a separate service.
