What is KVM VPS Hosting? How It Works & Why It Matters

Understand KVM virtualization for VPS hosting. How KVM differs from OpenVZ and LXC, and why it matters for your workloads.

What is KVM?

KVM (Kernel-based Virtual Machine) is a virtualisation technology built into the Linux kernel. It turns a physical server into a hypervisor — software that creates and manages multiple isolated virtual machines. Each virtual machine (your VPS) runs as if it were a completely independent physical server with its own CPU, RAM, storage, and network interface.

KVM in one sentence: Full hardware virtualisation that gives each VPS a completely isolated environment with genuine dedicated resources and a real independent kernel.

KVM vs OpenVZ vs LXC

Feature	KVM	OpenVZ	LXC/Docker
Virtualisation type	Hardware (Type 1)	OS-level	Container
Dedicated kernel	Yes	No (shared)	No (shared)
Docker support	Native	Limited	Yes (nested)
Custom OS / ISO	Yes	No	No
Resource guarantee	Dedicated	Burstable	Shared
Windows support	Yes	No	No

Why KVM Matters for Your VPS

KVM virtualisation means your VPS has a genuine dedicated kernel — not a shared one. This has several important practical implications:

Docker runs natively: No workarounds or nested virtualisation needed
Kubernetes is supported: Full container orchestration works out of the box
Custom kernels: Install any Linux kernel version you need
Windows Server: KVM supports running Windows guest OS fully
No noisy neighbours: Memory and CPU are genuinely dedicated, not bursted from a shared pool

Our KVM VPS Netherlands runs on AMD Ryzen 9950X hosts with hardware virtualisation extensions (AMD-V) enabled, providing the lowest overhead and best performance possible with KVM.

KVM Performance on AMD Ryzen

KVM has very low virtualisation overhead — typically less than 2% CPU overhead compared to running on bare metal. When combined with AMD Ryzen 9950X CPUs (Zen 5 architecture, high single-core clock), DDR5 RAM, and NVMe PCIe SSD, our Ryzen VPS Netherlands delivers the best performance available in Netherlands VPS hosting.

When KVM VPS is Essential

You specifically need KVM VPS (not OpenVZ or LXC containers) when:

Running Docker or Docker Compose
Running Kubernetes clusters
Requiring Windows Server OS
Running custom kernels or kernel modules
Running cryptocurrency nodes (Bitcoin, Monero) that require specific kernel features
Needing guaranteed — not burstable — CPU and RAM allocation

Frequently Asked Questions

Yes, for most use cases. KVM provides dedicated resources, a real isolated kernel, and Docker/Windows support that OpenVZ cannot offer. OpenVZ is more resource-efficient for the provider but offers worse isolation and fewer capabilities for customers.

Yes. KVM VPS supports Docker natively — no workarounds needed. Full kernel access means you can run Docker, Docker Compose, Docker Swarm, and Kubernetes exactly as you would on a physical server.

Yes. KVM supports running Windows Server as a guest OS. Our Netherlands VPS plans support Windows Server 2019 and 2022. See our Windows VPS Netherlands page for details.

A hypervisor is the software layer that manages virtual machines. KVM is a specific hypervisor technology built into the Linux kernel. Other hypervisors include VMware ESXi, Microsoft Hyper-V, and Xen. KVM is the most widely used open-source hypervisor.

Yes. KVM VPS is ideal for running cryptocurrency nodes like Bitcoin or Monero because it provides a dedicated kernel, genuine isolated resources, and supports any software installation. See our crypto VPS Netherlands page for use cases.
