# Overview #

`Kata Containers runtime` creates a Virtual Machine to isolate a set of
container workloads. The Virtual Machine requires a operating system
operating (`Guest OS`) to boot and create containers inside the guest
environment.

This repository contains tools to create a `Guest OS` for `Kata
Containers`.
