Free, cross-platform VM orchestration for AI workflows with built-in MCP integration, sandboxed code execution, and compliance-ready architecture (SOC 1/2/3, HIPAA, ISO 27001).
README
Free, cross-platform VM orchestration for AI workflows.
Virtualize gives AI agents (and humans) full VM lifecycle management with built-in MCP integration, sandboxed code execution, and a compliance-ready architecture (SOC 1/2/3, HIPAA, ISO 27001).
LLMs: Read AGENTS.md for machine-readable project context, algebra definitions, tool chain format, and architecture invariants.

Why Virtualize?
Most AI workflows need sandboxed environments — to run generated code safely, test deployments, or give agents real OS-level access. Existing solutions are either cloud-locked, expensive, or platform-specific.
Virtualize is:
- Free & open-source (Apache 2.0)
- Cross-platform — Linux (KVM), macOS (Hypervisor.framework), Windows (WHPX/Hyper-V)
- MCP-native — AI agents interact with VMs via the Model Context Protocol
- Compliance-ready — audit logging, encryption, integrity chains, policy controls

Formal Algebra
Virtualize is not just an MCP — it is an executable algebra. Every tool is a typed morphism over a formally defined state space, with verified axioms and constraint enforcement.
Classification
Virtualize MCP ≅ a typed, finite, partially-defined monoidal category with audit-preserving invariants
Structure
| Component | Definition |
|---|---|
Carrier set C |
{VM states, Sandbox states, Filesystem states, Audit states} |
Generators T |
13 typed morphisms (vm_create, vm_start, ..., compliance_report) |
Composition ∘ |
t_i ∘ t_j ∈ T* (free monoid over tools) |
Identity id |
id ∘ t = t = t ∘ id for all t ∈ T |
| Constraint subalgebra | T_valid ⊆ T* (compliance policies restrict valid compositions) |
Typed Transitions
Each tool is a morphism t_i : C_source → C_target with explicit preconditions:
vm_create : vm.nonexistent → vm.created
vm_start : vm.created | vm.stopped → vm.running
vm_stop : vm.running | vm.paused → vm.stopped
vm_destroy : vm.created | vm.running | vm.stopped | vm.paused → vm.destroyed
vm_exec : vm.running → vm.running (endomorphism)
Verified Axioms
$ virtualize algebra verify
PASS identity — id ∘ t = t = t ∘ id holds for all generators
PASS closure — All generators map C → C
PASS associativity — (t₁ ∘ t₂) ∘ t₃ = t₁ ∘ (t₂ ∘ t₃)
PASS audit_monotonicity — A_{n+1}.seq ≥ A_n.seq
PASS audit_irreversibility — ∄ t such that t(A_n) = A_{n-1}
PASS transition_determinism — All transitions are deterministic
Key Properties
- Non-commutative:
create ∘ start ≠ start ∘ create(proven in tests) - Audit chain:
A_{n+1} = H(A_n ∥ e_n)— monotonic, irreversible, append-only - Constraint subalgebra: Compliance policies define
T_valid ⊆ T*(e.g., SOC2 blocks file reads when audit is tampered) - Algebraic rewriting: Identity elimination, idempotent collapse, annihilation (
create ∘ destroy = id), dead code elimination
Plan Validation
Validate execution plans before running them:
# Valid lifecycle
$ virtualize algebra validate '[
["vm_create", null, {"name": "my-vm"}],
["vm_start", "my-vm", {}],
["vm_exec", "my-vm", {"command": "echo hello"}],
["vm_stop", "my-vm", {}],
["vm_destroy", "my-vm", {}]
]'
# → VALID — 5 steps validated
# Invalid: exec on nonexistent VM
$ virtualize algebra validate '[["vm_exec", "ghost", {}]]'
# → INVALID — vm_exec requires VM 'ghost' in {vm.running}, but it is in 'vm.nonexistent'
Plan Optimization
$ virtualize algebra rewrite '[
["identity", null, {}],
["vm_create", "vm-1", {"name": "vm-1"}],
["identity", null, {}],
["vm_start", "vm-1", {}],
["vm_status", "vm-1", {}],
["vm_status", "vm-1", {}],
["vm_destroy", "vm-1", {}]
]'
# → Original: 7 steps → Optimized: 4 steps (3 eliminated via algebraic laws)
Natural Language Agent
Ask in plain English — a small local LLM (Qwen 2.5 1.5B, ~1GB) translates your request into an algebraically validated tool chain. The algebra guarantees safety: invalid plans are rejected before touching any VM.
# Install agent dependencies
pip install -e ".[agent]"
# Ask anything
virtualize ask "start me a vm that i can connect to openclaw"
Output:
╭─────────────── Execution Plan ───────────────╮
│ │
│ 1. Create VM 'openclaw-vm' │
│ 2. Start VM on 'openclaw-vm' │
│ 3. Run `pip install openclaw && python -m │
│ openclaw` on 'openclaw-vm' │
│ │
╰───────────────────────────────────────────────╯
VALID — 3 steps, audit seq → 3
Add --execute (-x) to actually run the plan. Use --gpu-layers 0 for CPU-only inference.
How it works
User (English) → LLM → JSON tool chain → Compositor.validate() → Execute
↓ (if invalid)
Retry with error feedback
The LLM can hallucinate any plan it wants — the algebra's compositor validates every step against the typed transition rules before execution. Invalid plans are fed back to the LLM with the specific algebraic violation for self-correction (up to 2 retries).

Quick Start
Prerequisites
The easiest way — let Virtualize detect your OS and install everything:
pip install -e .
virtualize setup
This will detect your OS, distro, package manager, hardware acceleration, and GPU — then install QEMU with the correct commands for your platform.
Or install manually:
# Linux (Ubuntu/Debian)
sudo apt install qemu-system-x86 qemu-utils
# Linux (Fedora/RHEL)
sudo dnf install qemu-system-x86 qemu-img
# macOS
brew install qemu
# Windows
choco install qemu
# or download from https://qemu.org/download
Install Virtualize
pip install -e .
CLI Usage
# Create a VM
virtualize create my-dev-vm --cpus 4 --memory 4096 --disk 50
# Start it
virtualize start <vm_id>
# Run a command inside
virtualize exec <vm_id> "uname -a"
# Run sandboxed code
virtualize sandbox run "print('hello from sandbox')" --lang python
# List VMs
virtualize list
# Stop and destroy
virtualize stop <vm_id>
virtualize destroy <vm_id>
API Server + Web Dashboard
# Start the API server (includes dashboard at http://localhost:8420)
python -m uvicorn virtualize.api.server:app --host 0.0.0.0 --port 8420
MCP Server (for AI Agents)
Add to your MCP client configuration:
{
"mcpServers": {
"virtualize": {
"command": "python",
"args": ["-m", "virtualize.mcp_server.server"]
}
}
}
Or start via CLI:
virtualize mcp serve
Compliance
# Generate a SOC 2 compliance report
virtualize compliance report soc2
# Verify audit log integrity
virtualize compliance audit-verify
# Query audit events
virtualize compliance audit-query --actor alice --limit 20
