TL;DR: Embedded software guy needs to create a multi-instance sandbox environment in Jenkins for testing and not sure what good solutions are out there. Looking for suggestions.

So at work, we have these really cool integration tests that validate our system for flight safety. What's not so cool is that due to factors outside of my control, each test has to be run serially and the entire test suite can take many many hours. This is mostly due to a hardware limitation (not enough physical NICs), but there are other SW factors as well.

What I would like to do is somehow be able to wrap up all the resources into a neat little package and then deploy that package into some kind of virtual environment that can be instantiated on a Jenkins job. The NIC issue would be replaced with a virtual one and *theoretically* I should be able to spawn as many instances of this virtual environment as my CPU and RAM can handle. In short, I want to pseudo parallelize our test suite and drive down our testing time. Somehow I would need to be able to control this entire thing from a script of some sort.

Does anyone know of something out there that would satisfy these kinds of requirements? Double internet points if it's open source.
