krunsh
— Krunsh is a minimal Go CLI tool that executes newline-delimited shell commands inside an ephemeral KVM-based microVM, leveraging the libkrun library for lightweight virtualization. By piping commands from stdin, krunsh spins up a microVM, runs the specified commands using `/bin/sh -c`, captures the output, and discards the VM afterward, ensuring zero persistent state and strong process isolation.
