Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


Forget the question, we will use a layer 2 tunnel, because corosync requires
multicast and the Proxmox cluster software uses also only one IP address for
its services.

We will use a tunnel, a bridge and rapid spanning tree on the host or an
external device to provide us the replicated layer 2 connection.
