firecracker-kvm-dotnet

firecracker-kvm-dotnet

A Claude Code plugin marketplace for building Firecracker-style MicroVMs on the Linux KVM kernel module from .NET.

It ships a single plugin, firecracker-kvm-dotnet, which bundles four skills:

Skill	What it covers
firecracker-kvm-mechanics	Firecracker's fast launch path mapped to KVM APIs — memory/vCPU setup, the run loop, device minimization, and source mapping.
kvm-api-for-microvms	Direct Linux KVM MicroVM launcher mechanics: /dev/kvm ioctls, vCPU run loops, register/state restore, and low-level .NET interop.
firecracker-snapshot-pooling	Creating, loading, and pooling full/diff snapshots, MAP_PRIVATE restore, copy-on-write file strategies, and prebooted VM pools.
zeroboot-dotnet-cow-forking	ZeroBoot-style direct KVM fork engine from snapshots in .NET — mmap(MAP_PRIVATE), restored CPU state, minimal serial I/O, CoW clone pools.

Installation

In any Claude Code session, add this marketplace and install the plugin:

/plugin marketplace add arktoon/firecracker-kvm-dotnet
/plugin install firecracker-kvm-dotnet@firecracker-kvm-dotnet

You can also point at the full URL or a local path: /plugin marketplace add https://github.com/arktoon/firecracker-kvm-dotnet

Once installed, the skills activate automatically when your prompts match their descriptions (e.g. asking about KVM ioctls, Firecracker snapshots, or CoW VM forking).

To update later:

/plugin marketplace update firecracker-kvm-dotnet
