I was looking to setup Proxmox for my homelab soon but this comment got me interested in Incus. Mostly because I've never heard of any Proxmox alternatives before this. You can try out Incus in your browser here: https://linuxcontainers.org/incus/try-it/
The demo does take ~10m to get into a working instance.
