Proxmox vSwitch
A hypervisor doesn’t just carve a box into rooms — it has to wire those rooms together. Proxmox provides a virtual switch inside each host: a software bridge connecting the VMs and containers on that machine to one another and out to the physical network. It’s framing’s other half — the metal is split into rooms, and the soft switch is the corridor between them.
This is internal to a single box, and deliberately distinct from the mesh that joins separate hosts (see Wire › Mesh). One is the wiring within a frame; the other is the wiring between frames. The per-host bridge layout is recorded in the Hardware Manifest.
