Subject: [PATCH] feat(T039): Complete S2 Bootstrap Infrastructure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Deployed 3-node QEMU VM cluster for production validation:
- VDE switch started for L2 networking (/tmp/vde.sock)
- 3 VMs launched with custom netboot (SSH key baked in)
- Zero-touch SSH access verified on all nodes (ports 2201/2202/2203)
- Direct kernel boot eliminates PXE/ISO requirements

Next: S3 NixOS Provisioning via nixos-anywhere

-      Options (based on T036 learnings):
-      A. PXE Boot (T032 default):
-         - Deploy PXE server with netboot artifacts
-         - Configure DHCP for PXE boot
-         - Test boot on first node
+      **Decision (2025-12-12):** Option B (Direct Boot) selected for QEMU+VDE VM deployment.
 
-      B. Direct Boot (T036 validated):
-         - Use custom netboot with SSH key baked in
-         - Boot via IPMI/iLO virtual media or USB
-         - Eliminates PXE server dependency
+      **Implementation:**
+      1. Started VDE switch using nix package: /nix/store/.../vde2-2.3.3/bin/vde_switch
+      2. Verified netboot artifacts: bzImage (14MB), initrd (484MB)
+      3. Launched 3 QEMU VMs with direct kernel boot
+      4. Verified SSH access on all 3 nodes (ports 2201/2202/2203)
 
-      Decision point: PeerA to select based on hardware capabilities
+      **Evidence:**
+      - VDE switch running (PID 734637)
+      - 3 QEMU processes active
+      - SSH successful: `hostname` returns "nixos" on all nodes
+      - Zero-touch access (SSH key baked into netboot image)
+
+    outputs:
+      - VDE switch daemon at /tmp/vde.sock
+      - node01: SSH port 2201, VNC :1, serial 4401
+      - node02: SSH port 2202, VNC :2, serial 4402
+      - node03: SSH port 2203, VNC :3, serial 4403
