slim will manufacture a VM from a Dockerfile. Slim works by building and extracting a rootfs from a Dockerfile, and packaging a corresponding kernel and initrd into a desired image.
This ends up in a real VM that can boot straight, while the utilization of very little sources—all with a pair of traces in a Dockerfile.
