ntoseye
Drive the ntoseye Windows kernel debugger from Python, and run it from the command line.
The standalone SDK uses the 0.37 API; see docs/sdk.md for
address-space-bound views, run control, and the 0.36 migration table. The
package also installs the ntoseye command (the REPL, ntoseye mcp, dap,
and gdbserver), which runs Python custom commands from
~/.ntoseye/commands/: uv tool install ntoseye or pipx install ntoseye.
Install
pip install ntoseye
Or build from source into a virtualenv with maturin:
cd python
python3 -m venv .venv
source .venv/bin/activate
pip install maturin
maturin develop --release
Or build a wheel and install it:
cd python
maturin build --release --out dist
pip install dist/ntoseye-*.whl
Quick start
import ntoseye
with ntoseye.attach() as dbg: # defaults to the kd backend
print(dbg.inspect.version())
for proc in dbg.processes:
print(proc.pid, proc.name)
For read-only inspection of a paused VM, select backend="memory". Processes
are handles keyed by PID (dbg.processes[pid]); memory and modules for a
specific process are available through proc.memory and proc.modules.
Type stubs
ntoseye/_ntoseye.pyi is generated from the extension by PyO3's
introspection: signatures come from the Rust types and docstrings from the
doc comments. After changing the Rust surface, regenerate it and commit the
result (CI fails when the checked-in stub differs from a fresh one):
maturin develop --release --generate-stubs
Tests
pip install pytest mypy
pytest tests # target-free surface tests
mypy --strict -p ntoseye # the stub and package type-check
NTOSEYE_TEST_BACKEND=kd NTOSEYE_TEST_CONNECT=/tmp/ntoseye-kd.sock pytest tests
The last line also runs tests/test_live.py against a guest: it breaks in,
steps, sets breakpoints on hot kernel functions, and resumes the guest.
Add NTOSEYE_TEST_MEMORY_SOURCE=kd to read guest memory over KD instead of
from the VM process: no root needed for UTM on macOS, and required for a
remote target.
Releasing portable wheels
Release wheels are built by .github/workflows/release.yml with PyO3/maturin-action on native GitHub runners:
- Linux x86-64 and ARM64 build on
ubuntu-22.04andubuntu-24.04-arminside thequay.io/pypa/manylinux_2_28_*images, producingmanylinux_2_28wheels. - Apple Silicon uses the native ARM64
macos-14runner.
Each wheel then passes twine check and the target-free tests (tests/test_surface.py) in a clean virtual environment before upload.
To reproduce a Linux release wheel locally (from the repository root, Docker required):
docker run --rm -e CARGO_TARGET_DIR=/tmp/target -e HOST_IDS="$(id -u):$(id -g)" \
-v "$PWD":/io -w /io/python quay.io/pypa/manylinux_2_28_$(uname -m) bash -c '
dnf install -y clang &&
curl -sSf https://sh.rustup.rs | sh -s -- -y --profile minimal &&
source ~/.cargo/env &&
/opt/python/cp312-cp312/bin/pip install maturin &&
/opt/python/cp312-cp312/bin/maturin build --release --out dist --compatibility manylinux_2_28 &&
chown -R "$HOST_IDS" dist'
