How about some sort of package management that lets you define and
configure the VM?

This is currently done from "the inside", i. e. when the VM is running,
with whatever installer and package manager a distribution comes

Why not do it from "the outside", i. e. before the VM even exists,
creating it in the process?  Define some sort of API so that the same
"VM creator tool" could be used with different distributions.

Knowledge is volatile and fluid.  Software is power.
