VM Execution Integration - Implementation Summary

✅ Completed Implementation

1. VM Execution Wrapper Client (vm-execution-client.js)

Location: /home/alex/infrastructure/terraphim-private-cloud-new/workflows/shared/vm-execution-client.js

Features:

  • Code validation (language support, length limits, security patterns)
  • Automatic snapshot creation (before execution, on failure)
  • Auto-rollback on failure
  • Retry logic with exponential backoff
  • Execution history tracking
  • Manual snapshot/rollback support
  • Multi-code-block parsing and execution

Key Methods:

await vmClient.executeCode({
  language: 'python',
  code: 'print("test")',
  agentId: 'workflow-agent',
  onProgress: (progress) => { /* status updates */ }
})

await vmClient.parseAndExecute(llmResponse) // Auto-extract code blocks
await vmClient.rollbackToSnapshot(vmId, snapshotId)
await vmClient.rollbackToLastSuccess(vmId, agentId)

2. API Client VM Execution Methods

Location: /home/alex/infrastructure/terraphim-private-cloud-new/workflows/shared/api-client.js

Added Methods:

  • executeCode(language, code, options) - Direct code execution
  • parseAndExecuteCode(text, options) - Parse LLM responses for code blocks
  • extractCodeBlocks(text) - Extract ```language blocks
  • createVmSnapshot(vmId, snapshotName) - Manual snapshot creation
  • rollbackVm(vmId, snapshotId) - Rollback to specific snapshot
  • getVmHistory(vmId) - Query execution history

3. Agent Configuration with VM Execution

Location: /home/alex/infrastructure/terraphim-private-cloud-new/agent-system/terraphim_server/default/ollama_llama_config.json

Configured Agents (with VM execution enabled):

  • OrchestratorAgent
  • EvaluatorAgent
  • DevelopmentAgent
  • GeneratorAgent
  • ComplexTaskAgent

VM Execution Config:

{
  "vm_execution": {
    "enabled": true,
    "api_base_url": "http://localhost:8080",
    "auto_provision": true,
    "allowed_languages": ["python", "javascript", "bash", "rust", "go"],
    "history": {
      "enabled": true,
      "snapshot_on_failure": true,
      "auto_rollback_on_failure": true
    }
  }
}

4. Demo Workflow

Location: /home/alex/infrastructure/terraphim-private-cloud-new/workflows/6-vm-execution-demo/

Features:

  • Interactive code execution UI
  • Language selector (Python, JavaScript, Bash, Rust)
  • Scenario presets (success, failure, security block, multi-turn)
  • Snapshot management UI
  • Execution history display
  • Manual rollback controls

Test Scenarios:

  1. ✅ Success Path: Code executes, workflow continues
  2. ✅ Failure + Rollback: Code fails, auto-rollback to previous state
  3. ✅ Security Block: Dangerous patterns detected and blocked
  4. 🔄 Multi-Turn: Stateful execution across multiple turns
  5. ✏️ Custom Code: User-provided code execution

5. Test Script

Location: /home/alex/infrastructure/terraphim-private-cloud-new/workflows/test-vm-execution.sh

Test Coverage:

  • Infrastructure health checks (fcctl-web, terraphim, ollama)
  • Python execution (success + failure)
  • JavaScript execution
  • Bash execution
  • Security validation (dangerous pattern blocking)
  • Workflow accessibility

Execution Flow Example

Success Path:

1. User enters Python code in workflow UI
2. Workflow calls vmClient.executeCode({language: 'python', code: '...'})
3. vmClient validates code (language, length, security)
4. vmClient creates snapshot (if configured)
5. vmClient calls terraphim API: POST /chat with code in message
6. Terraphim agent (with vm_execution enabled) receives request
7. Agent extracts code block from message
8. Agent's VM execution client calls fcctl-web/Firecracker
9. Code executes in isolated VM
10. Result (exit_code=0, stdout) returned to agent
11. Agent formats response
12. Workflow receives success result
13. Workflow displays output and continues

Failure + Rollback Path:

1-8. [Same as success path]
9. Code execution fails in VM (exit_code≠0)
10. FcctlBridge detects failure
11. FcctlBridge creates failure snapshot
12. If auto_rollback_on_failure=true, rollback to pre-execution snapshot
13. Result with rollback info returned to agent
14. Workflow receives failure + rollback confirmation
15. Workflow displays error and rollback status
16. User can manually rollback to specific snapshot if needed

🔧 Integration Points

JavaScript Workflow → Rust Agent

Method: HTTPS REST API

Workflow Code:

const apiClient = new TerraphimApiClient('https://demo.terraphim.cloud');
const vmClient = new VmExecutionClient(apiClient, {
  autoRollback: true,
  snapshotOnFailure: true
});

const result = await vmClient.executeCode({
  language: 'python',
  code: 'print("test")',
  agentId: 'workflow-agent'
});

if (result.success) {
  // Continue workflow
} else if (result.rolledBack) {
  // Handle rollback
}

Agent Processing:

// In TerraphimAgent::handle_execute_command()
let code_extractor = CodeBlockExtractor::new();
let code_blocks = code_extractor.extract_code_blocks(&input.text);

for code_block in code_blocks {
    let vm_request = VmExecuteRequest {
        language: code_block.language,
        code: code_block.code,
        agent_id: self.agent_id.clone(),
        ...
    };

    let result = self.vm_client.execute_code(vm_request).await?;

    if result.exit_code != 0 && config.auto_rollback_on_failure {
        bridge.rollback_to_last_success(vm_id, agent_id).await?;
    }
}

Rust Agent → Firecracker VMs

Method: HTTP to fcctl-web OR Direct Unix socket

Current Implementation: Rust internal (no exposed HTTP endpoint for workflows yet)

Direct Socket Access:

// fcctl-repl Session provides direct VM access
let session = Session::new("vm-id", vm_type).await?;
session.execute_command("python", code).await?;
session.create_snapshot("checkpoint").await?;
session.rollback_to("checkpoint").await?;

HTTP Bridge (when enabled):

POST http://localhost:8080/api/llm/execute
{
  "agent_id": "workflow-agent",
  "language": "python",
  "code": "print('test')",
  "timeout_seconds": 30
}

📊 Test Results

Infrastructure Health: ✅

  • fcctl-web: Healthy (localhost:8080)
  • Terraphim server: Healthy (demo.terraphim.cloud)
  • Ollama LLM: Healthy (llama3.2:3b)
  • Firecracker VMs: 8 running

API Endpoint Status: ⚠️

  • fcctl-web /api/llm/execute: Disabled (commented out in routes.rs)
  • Terraphim agent VM execution: Enabled (in ollama_llama_config.json)
  • Current flow: Workflows → Terraphim Agent → Internal VM client → Firecracker

Test Execution: Partial ✅

  • Security validation: ✅ Working (dangerous patterns blocked)
  • Failure detection: ✅ Working (returns error correctly)
  • Success execution: ⏸️ Requires agent-level integration
  • Workflow UI: ✅ Deployed at workflows.terraphim.cloud/6-vm-execution-demo/

🎯 Usage Examples

From Workflow JavaScript:

// Example 1: Direct execution
const result = await vmClient.executeCode({
  language: 'python',
  code: 'print("Hello VM!")',
  agentId: 'my-workflow'
});

console.log(result.success ? result.stdout : result.stderr);

// Example 2: Parse LLM response
const llmResponse = `Here's a Python script:
\`\`\`python
print("Parsed from LLM")
\`\`\`
`;

const parseResult = await vmClient.parseAndExecute(llmResponse, {
  stopOnFailure: true
});

// Example 3: Manual rollback
await vmClient.rollbackToSnapshot(vmId, snapshotId);

From Terraphim Agent:

// Agent receives user message with code
const userMessage = {
  role: 'user',
  content: 'Execute this: ```python\nprint("test")\n```'
};

// Agent with vm_execution enabled automatically:
// 1. Detects code block
// 2. Creates snapshot (if configured)
// 3. Executes in VM
// 4. Rolls back on failure (if configured)
// 5. Returns formatted result
