With SSH Configuration (~40 minutes)

Once SSH is configured on VM:

  1. Install COSMIC desktop (15 min, automated)
  2. Deploy ionChannel (10 min, automated)
  3. Install RustDesk (5 min, automated)
  4. Test screen sharing (10 min, RustDesk's PipeWire)
  5. Test input injection (included, ionChannel portal)

Future (Optional, ~2-3 days)

  • PipeWire event loop integration

  • Endpoint discovery: D-Bus + port probing
  • Service discovery: Runtime capability queries

Zero Hardcoding ✅

  • All ports/addresses configurable
  • Constants for defaults only
  • Environment-driven configuration
  • Runtime-only binding

Agnostic & Capability-Based ✅

  • VmBackendProvider trait for VMs
  • CompositorBackend trait for display servers
  • CaptureTier enum for screen capture
  • Selection by capability, not name

Modern Idiomatic Rust ✅

⏳ Known Limitations & Future Work

SSH Configuration (Deployment Detail)

Current State:

  • VMs provision successfully
  • Network configured correctly
  • SSH requires manual setup

Solutions:

  1. Cloud-Init (Recommended)

    • Use Ubuntu cloud image
    • Pre-configure SSH keys
    • Fully automated

  2. Console Setup (Immediate)

    • Access via virt-manager
    • Configure SSH manually
    • Continue with automation

  3. Custom Image (Production)

    • Create pre-configured image
    • Zero manual steps
    • Production deployment

PipeWire Event Loop (Optional)

Current State:

  • Architecture complete
  • Permission flow working
  • Event loop pending

Remaining Work:

  • ~200 lines of PipeWire async integration
  • Estimated: 2-3 days
  • Not required for RustDesk testing

Note: RustDesk has its own PipeWire capture, so ionChannel provides the portal infrastructure and input injection, which are complete.

📝 Lessons Learned
