One of the stumbling blocks I ran into when trying out NixOS was that I couldn’t run it under Proxmox, my preferred virtual machine server. Through some trial and error, I figured out how to install NixOS as a Proxmox container. Download the NixOS container image First, download the latest NixOS x86_x64 container image. For other hardware architectures, see this Github comment. At the time of this writing, the latest NixOS container build is 235933548, but you can just click whatever is the latest build as you read this.
