A clean start – How to prepare a minimal Debian template for LXC containers
In my recent push for more virtualization I sat down today and constructed a very minimal Debian template that only has the bare necessities installed to be able to communicate on the network and operate the base-system. This template will be used to spin up LXC containers on a hypervisor, which is very fast and has virtually no overhead.

Proxmox on Debian at Hetzner with multiple IP addresses
I’ve spent most of my day today trying a plethora of different ways on how to configure Proxmox on a Hetzner server with multiple IP addresses. Most of the tutorials I found online gave a good deal of information but where lacking in one or two crucial details. Shortly before I was ready to throw my computer out of the window, I had success and managed to get everything set up the way I wanted it.
This aims to be the definitive guide on how to accomplish the aforementioned task. When ready the setup includes the following features:
- Host bound to main IPv4 address, that comes with the server (and one of the 18,446,744,073,709,551,616 included IPv6 addresses)
- Every IPv4 address of a separately delegated subnet usable for virtual machines
- Internal private network for inter-virtual machine communication and non publicly accessible VMs
