Ditch Proxmox. Incus is the powerful, modern, community driven solution

By default Incus is setup in bridge network type with NAT enabled! But we don't want NAT (a sub-network is created), to facilitate reaching our VMs outside of the host (from other computers in our home network). See docs on how to disable. Look for ipv4.nat, ipv6.nat boolean flags.

Addressing quirks on Alpine Linux host

I choose to run Alpine as the hypervisor host. See this article, it's very minimal and ideal for the purpose. You can see in the docs, how to install Incus on it. But I noticed a couple of quirks in running it..

When launching images I get an error in the likes of tap<>: No such file or directory. You need to enable the module tun before use:

echo tun | doas tee -a /etc/modules
reboot

Second the docs state that you need to add yourself to incus-admin group. This was not the case in my installation. I had to add to incus group instead and got admin privileges. To check which group to assign, run:

ls -l /var/lib/incus/unix.socket
srw-rw----    1 root     incus            0 May 16 23:47 /var/lib/incus/unix.socket
