test-vm

Runs examples/smoke/smoke.yaml — the agent replies with "vm-ok 2+2=4". No tool use required; any model that generates text will pass. Success is success: true with output containing vm-ok.

All commands run from the repository root.

Usage: /test-vm [ollama [model] | claude | claude-personal]

• ollama [model] — local Ollama (default model: phi4-mini)
• claude — Anthropic API key (ANTHROPIC_API_KEY must be set)
• claude-personal — personal Claude account (macOS: extracted from Keychain; Linux: staged from ~/.claude/)
• no argument — defaults to ollama phi4-mini

Recommended Ollama models (2–4 GB RAM, reliable with claude-code): phi4-mini, gemma3:4b, llama3.2:3b. Avoid *-coder variants — they don't follow the agentic protocol well.

Step 1 — Prerequisites

Kernel

Check for an existing kernel file. macOS needs an uncompressed kernel (vmlinux-*); Linux can use the host kernel (vmlinuz-*):

ls target/vmlinux-arm64 2>/dev/null \
  || ls target/vmlinux-amd64 2>/dev/null \
  || ls /boot/vmlinuz-$(uname -r) 2>/dev/null \
  || echo "MISSING"

If missing, download it (the script caches the result in target/):

scripts/download_kernel.sh

After downloading, run the check again to confirm and record the path — it is needed in Step 4.

Rootfs

ls target/void-box-rootfs.cpio.gz 2>/dev/null || echo "MISSING"

If missing, build it (auto-detects the claude binary on PATH or ~/.local/bin/claude):

scripts/build_claude_rootfs.sh

Run the check again to confirm. If it still fails, tell the user to set CLAUDE_BIN=/path/to/claude and retry.

Step 2 — Build and sign

cargo build --release --bin voidbox

macOS only — Apple Virtualization.framework requires the entitlement:

codesign --force --sign - --entitlements voidbox.entitlements target/release/voidbox

Step 3 — Provider setup

Ollama

Check Ollama is installed:

which ollama || echo "NOT INSTALLED"

If not installed: macOS → brew install ollama; Linux → curl -fsSL https://ollama.com/install.sh | sh. Stop until installed.

Check Ollama is running and bound to 0.0.0.0 (required so the guest VM can reach it):

curl -sf http://localhost:11434/api/tags > /dev/null && echo "running" || echo "not running"

If not running, start it in the background:

OLLAMA_HOST=0.0.0.0:11434 ollama serve > /tmp/ollama-serve.log 2>&1 &
for i in $(seq 1 10); do curl -sf http://localhost:11434/api/tags > /dev/null && break || sleep 1; done
curl -sf http://localhost:11434/api/tags > /dev/null || { echo "Ollama failed to start:"; cat /tmp/ollama-serve.log; }

If it was already running: warn the user that Ollama must be listening on 0.0.0.0:11434 (not 127.0.0.1) so the guest VM can reach it through the NAT gateway. If unsure, stop Ollama and restart it with OLLAMA_HOST=0.0.0.0:11434 ollama serve.

Check the model is pulled; pull it if not:

ollama list | grep -F "MODEL_NAME" || ollama pull MODEL_NAME

(substitute MODEL_NAME with the actual model, e.g. phi4-mini)

Set the Ollama base URL for use in Step 4:

• macOS: http://192.168.64.1:11434 (VZ NAT gateway)
• Linux: http://10.0.2.2:11434 (SLIRP gateway)

Claude (API key)

[ -n "$ANTHROPIC_API_KEY" ] && echo "key set" || echo "MISSING — export ANTHROPIC_API_KEY=sk-ant-..."

If not set, stop and ask the user to export it.

Claude (personal account)

Check authentication status using the CLI (exits 0 if logged in, 1 if not):

claude auth status

If not authenticated, stop and tell the user to run claude auth login first, then retry.

No manual credential staging is needed — the claude-personal LLM provider discovers OAuth credentials automatically (macOS Keychain / Linux ~/.claude/.credentials.json), stages them to a secure temp directory, and mounts them into the guest VM.

Step 4 — Run

Use the kernel path found in Step 1 and the URL from Step 3 in the commands below.

Ollama:

VOIDBOX_LLM_PROVIDER=ollama \
VOIDBOX_LLM_MODEL=<model> \
VOIDBOX_LLM_BASE_URL=<ollama-url> \
VOID_BOX_KERNEL=<kernel-path> \
VOID_BOX_INITRAMFS=target/void-box-rootfs.cpio.gz \
./target/release/voidbox run --file examples/smoke/smoke.yaml

Claude (API key):

VOID_BOX_KERNEL=<kernel-path> \
VOID_BOX_INITRAMFS=target/void-box-rootfs.cpio.gz \
./target/release/voidbox run --file examples/smoke/smoke.yaml

Claude (personal account):

VOIDBOX_LLM_PROVIDER=claude-personal \
VOID_BOX_KERNEL=<kernel-path> \
VOID_BOX_INITRAMFS=target/void-box-rootfs.cpio.gz \
./target/release/voidbox run --file examples/smoke/smoke.yaml

Step 5 — Verify

The run output includes a success: field and an output: section. Check:

• success: true — the VM ran the agent without error
• output contains vm-ok — the LLM responded correctly

If success: false or output is missing vm-ok, report the full output for diagnosis.
