把 Docker Image 轉成 VM Image

看到「ottomatica/slim」這個專案:

slim will build a micro-vm from a Dockerfile. Slim works by building and extracting a rootfs from a Dockerfile, and then merging that filesystem with a small minimal kernel that runs in RAM.

This results in a real VM that can boot instantly, while using very limited resources. If done properly, slim can allow you to design and build immutable unikernels for running services, or build tiny and embedded development environments.

從 screenshot 可以看到會產生 ISO Image:

產生的 ISO Image 可以透過 HyperKit (在 macOS 時) 或是 VirtualBox 跑起來。

實際用途不知道多大,算是一種嘗試?
