Hi Pablo/Eric/All, I guess there are many different strategies to handle it But maybe what you're looking for is a customized version of dosemu (http://www.dosemu.org)? It seems that usually, unikernels are some sort of "container" or application-oriented operating system (https://www.lisha.ufsc.br/pub/Frohlich_2001.pdf) in the sense that you embed a single application together with the kernel (single address space operating system with just enough drivers/infrastructure)
