# Finding a Wasm Runtime Unikernel for libkrun

There’s this interesting idea of adding support for running Wasm/WASI payloads in libkrun, which is something we could easily achieve by simply embedding a Wasm runtime, statically built for Linux, into initrd. Now, the problem with this approach is that, despite having a payload (the Wasm runtime) with a well-known behavior, we would still be using a (built with a minimal config, but otherwise complete) Linux kernel, despite only needed a small amount of its functionality.

# Running Linux microVMs on macOS (M1/M2)

Sometimes, while working on macOS, you may find the need to test something quick on Linux, or use some utility that’s only available on this OS. But, of course, you don’t want to go through all the process of creating the VM from scratch. The good news is, you don’t need to! Using krunvm you can create and start a microVM from a regular container image (that is, an OCI image), in just two commands and a couple of seconds.
