What is an LXC VPS?

An LXC VPS is the cheapest way to get a real, always-on Linux server - often less than half the price of a comparable virtual machine. But "cheaper" comes from a genuine technical difference, not a discount gimmick. Here is what an LXC VPS actually is, what it is brilliant at, and the one limit you should know before you buy.

What an LXC VPS actually is

LXC (Linux Containers) is operating-system-level virtualization. Instead of emulating virtual hardware and booting a whole guest OS the way a KVM VPS does, an LXC container is an isolated slice of the host: your own root filesystem, processes, users and network, all fenced off from every other tenant - but sharing the host's Linux kernel. At InstantNode every container is unprivileged and confined by AppArmor, and lxcfs makes /proc, load and memory show your numbers, not the host's.

Why it is cheaper

There is no second kernel to boot and no virtual hardware to emulate, so the overhead is close to zero and the host can run more containers per machine. That density is exactly why an LXC VPS starts at €1.50/mo while an equivalent KVM starts higher - you are paying for the same AMD EPYC cores and NVMe storage, just without the hypervisor tax.

What it is great for

Anything that is "a normal Linux server" runs beautifully: web apps and APIs, Discord and Telegram bots, reverse proxies, small databases, Git servers, monitoring agents, cron jobs, VPNs, game-server panels. It boots in a second or two, so it is also perfect for throwaway or short-lived work. Docker runs fine inside it for the vast majority of images.

The one limit to know

Because the kernel is shared, you cannot load custom kernel modules, run your own kernel, or nest full virtual machines inside an LXC VPS. If your project needs any of those - a custom kernel, KVM-inside-KVM, or the very hardest isolation between tenants - that is what our KVM VPS is for. For everything else, LXC gives you the same hardware for less.

LXC or KVM?

Simple rule: pick LXC when you want the best value for a standard Linux workload, and KVM when you need kernel-level control or maximum isolation. Both run on the same EU hardware, both give you full root, and you can start on one and migrate later.
