QEMU Socket Networking VM Cluster
Architecture
Topology: 4 QEMU VMs connected via multicast socket networking (230.0.0.1:1234)
VMs:
- pxe-server (192.168.100.1) - Provides DHCP/TFTP/HTTP services
- node01 (192.168.100.11) - Cluster node
- node02 (192.168.100.12) - Cluster node
- node03 (192.168.100.13) - Cluster node
Network: All VMs share L2 segment via QEMU multicast socket (no root privileges required)

- node01: 52:54:00:00:01:01
- node02: 52:54:00:00:01:02
- node03: 52:54:00:00:01:03
Provisioning Flow
- Start PXE server VM (Alpine Linux with dnsmasq)
- Configure DHCP/TFTP/HTTP services
- Deploy NixOS netboot artifacts
- Start node VMs with PXE boot enabled
- Nodes PXE boot and provision via nixos-anywhere
