I have a cluster of 3 Proxmox hosts, mostly to teach myself about clustering. I have two Vyos instances running VRRP between them. If the primary fails, the secondary sees the VRRP state change, runs a small script to bring up the PPPoE interface and we're away laughing. It syncs state, so people notice ~8-10 seconds of packet loss and everything just keeps going. It's quite nerdy though. And all it does is move the single point of the failure to the switch (required for the hosts to talk to each other for VRRP etc) Proxmox is so reliable in my experience though, but I don't tend to fiddle with it, just set and forget.
