Runs untrusted code in a throwaway smolvm microVM against a repo it must not modify, with no network unless explicitly granted, and collects artifacts from a writable output directory. Use when executing an agent's generated script, a pull request's test suite, or any code that should not be trusted with the host; when a workload needs egress granted one host at a time; or when a run has to be cancelled, because Ctrl-C on the wrapper script leaves the VM running, and on releases before v1.20.2…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Running untrusted work in a throwaway machine Verified on **smolvm v1.23.0** on macOS arm64, 2026-10-04, by the offline route, the network-on route and the cancel; on Linux aarch64 by the offline route and the cancel on v1.20.2, 2026-09-29, and the network-on route on v1.18.2, 2026-09-24. Done means the command's output landed in your writable directory, the repo is unchanged, the workload could not reach the network, and nothing is left running. The Linux runs used the scripts of their date; this version's preflight, run and cleanup scripts ran on Linux aarch64 on v1.22.2 on 2026-10-03. **On macOS from v1.24.0 the offline route does not run** ([#1819](https://github.com/smol-machines/smolvm/issues/1819)). Every `--oci-cache` run, the bake's own included, fails with `agent did not become ready within 30 seconds`: measured on v1.24.0, v1.24.1, v1.25.0, v1.25.1, v1.27.3, v1.28.1 and v1.29.0, while v1.23.3 and v1.23.7 boot the same command on the same host. The preflight says `offline_shape=unavailable` there and `bake.sh` says `result=FAILED`. For a run with no network, use the persistent machine with no network in …

How to install
mdr add smol-machines/smolvm/throwaway-machine@sha256:8a1ff25230020e23The line at the top of this page pins the label git:20261016.432b170, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
