In my GitHub repository of L1VM I added build directories for OSv unikernel support.
The goal is here to put the L1VM in a image together with the OSv unikernel.
You need to install the "capstan" build tool of OSv first. The build script makes an Qemu .img file which can run by Qemu or be installed on real hardware.
One demo shows how to load a module, in this case the math module. So you can load modules from your L1VM programs too!
