Run Arch Linux on an Offshore VPS

Arch Linux on a KVM virtual server

A KVM virtual server gives Arch Linux its own kernel, its own /proc, and no shared namespace, unlike container-based VPSes. That matters for a rolling distro that ships a stock kernel you can swap for a custom one. You can boot a custom ISO, run nested virtualisation, and use raw sockets. What you sign up for is administration: updates are always current, but you own the consequences. The documentation is outstanding, so the discipline is learnable, but an attentive administrator is not optional.

People run bleeding-edge software that exists nowhere else, often via the AUR. The always-current packages suit personal servers and tools where you want the newest features. The stated weakness is that rolling updates can break things, so workloads here tend to be ones you can rebuild quickly. It is not the choice for a passive, set-and-forget production load.

How much machine Arch Linux actually needs

Before your application takes a byte, Arch needs at least 512 MB just to boot; a 2 GB floor gives you headroom for package updates and the base system's running services. For a minimal server with one or two applications, start at 2 GB. Disk is the cheaper lever: 100 GB NVMe at $8 per month covers package caches and the AUR build directory.
