Common questions

Is GuestKit safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.9) reached the registry 20 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

GuestKit

Know it will boot. Before you power it on.

Offline VM intelligence and migration assurance. GuestKit reads a VM disk while the guest is off, scores first-boot readiness 0–100, repairs it through a plan you can read, and certifies cutover with a signed Passport.

6 disk formats · 0–100 boot score · 0 appliance daemons · 8 migration targets · Apache-2.0

What's new

Release	What changed
Agent (1.2.6)	Per-container eBPF network policy and BPF-LSM controls in the guest agent (`guestkit.netpolicy` / `guestkit.lsm`), off by default, audit first, enforce only under a time-bound lease
1.2.5	Offline inject on `run_migrate_repair`: hostname, network, users, services, first-boot scripts, cloud-init, AD rejoin, Windows KMS and RDP, appended to the repair plan
1.2.5	Online snapshots freeze the filesystem through the privileged helper, so KubeVirt snapshots of PVC-backed VMs work with the unprivileged agent
1.2.5	Linux agent connects to the virtio channel on stock distros (udev rule shipped in DEB, RPM and tarball); concurrent NBD mounts no longer race
1.2.2	Web Image Vault reaches TUI parity: inventory tabs, Assurance (plan, passport, repair preview and gated apply), Profiles and Files
1.2.0	`guestkit-qemu` assured QEMU/VirtIO runtime, `guestkit vm`, `virtctl-guestkit guestfs`, the cutover bundle and `guestkit shrink` for oversized disks

Full history: CHANGELOG.md.

Why GuestKit

Every hypervisor exit fails the same way: you discover the disk was broken at 2am, in the cutover window, after power-on. GuestKit reads the disk while the guest is off — qcow2, VMDK, VHDX, VHD, VDI or raw — through its own pure-Rust engine (NBD or loop mount). There is no appliance daemon and no "power it on and see".

When this happens…	GuestKit gives you…
"Will it boot?" is answered at power-on	An offline doctor score (0–100) with a root-cause chain for each blocker
Each migration relies on scripts and tribal knowledge	Structured plans in JSON/YAML and a CI gate on the same score
Cutover weekend is full of surprises	Hypervisor-aware migrate-plan and day-0 packs, for 8 targets
There is no audit trail of what was checked	A signed Cutover Passport per disk
Repairs are hand edits inside a mounted image	Fix plans you can read, applied with backups and rollback
Migration order is guessed by hand	`fleet wave-plan`: dependency-aware waves

Fixes are never implicit. Repairs go through a plan you can read, applied with backups and rollback, and the same score drives the CI gate, the signed Cutover Passport, and assured QEMU launch.

Boot-readiness scoring

First-boot probability 0–100, the blockers explained, and a reviewable fix plan.

The cutover problem

Offline repair

Repairs go through a plan you can read, applied with backups and rollback.

What you can do

Migration assurance

The same score drives the CI gate, the signed Cutover Passport and assured QEMU launch.

Quick start

Engine and formats

A pure-Rust engine over qcow2, VMDK, VHDX, VHD, VDI and raw, through NBD or loop mount.

Platform layout

Suite hand-offs

Export with Transiva, convert and deploy with h2kvm, assure with GuestKit, operate on Zorvia or Zeus OS.

Who does what

CLI, TUI, web, CI

CLI, TUI, QEMU, Python, web console, in-guest agent and a GitHub Action.

Run the web stack

70+ commands · 6 disk formats · 0 appliance daemons · 8 migration targets · Apache-2.0

GuestKit vs libguestfs + virt-v2v

	GuestKit	libguestfs + virt-v2v
Disk access	Rust engine; guest files reached through `qemu-nbd` or loop mounts on the host	Launches a small appliance VM to read and edit the disk
Boot readiness	`doctor`: a 0–100 first-boot score per target, with blockers explained	Inspection and conversion; no readiness score
Migration plan	`migrate-plan` per target (`kvm`, `proxmox`, `qemu`, `kubevirt`, `aws`, `azure`, `gcp`, `hyperv`)	`virt-v2v` converts a guest to run on KVM
Repair	Fix plans with backups and rollback; `rescue` for SSH, GRUB and passwords	`virt-customize`, `virt-rescue` and `guestfish` for scripted edits
Cutover evidence	Signed Cutover Passport and a GitHub Action that fails below a score	Not part of the toolkit
Interfaces	CLI, TUI, Python, web console, in-guest agent, GitHub Action	CLI tools and language bindings
Choose libguestfs when		You need its broad filesystem and OS coverage, or virt-v2v's end-to-end conversion, and have no need for a score or a cutover record

GuestKit sits next to conversion tools rather than replacing all of them: h2kvm converts and deploys, and calls GuestKit for the offline fixes.
