Hostinger KVM VPS: What It Means and Why It Matters
Hostinger uses KVM (Kernel-based Virtual Machine) virtualization for all VPS plans, which provides true hardware-level isolation. Unlike OpenVZ containers, KVM guarantees your CPU and RAM allocation, supports any operating system, and allows full kernel access. This means better security, no resource overselling, and compatibility with Docker and custom kernels.
What Is KVM Virtualization?
KVM creates fully isolated virtual machines with dedicated resources, their own kernel, and support for any OS and Docker.
KVM (Kernel-based Virtual Machine) is a full virtualization technology built into the Linux kernel. It creates completely isolated virtual machines, each with its own dedicated kernel, memory space, and virtual hardware. When you get a KVM VPS, you're getting a true virtual machine — not a container sharing the host kernel.
This matters because: your resources are truly dedicated (no overselling), you can run any OS (not just Linux), Docker and custom kernels work out of the box, and other users on the same physical server can't impact your performance.
KVM vs OpenVZ: Why It Matters
Many budget VPS providers still use OpenVZ to cut costs. Here's why Hostinger's KVM approach is better:
- Resource isolation: KVM = guaranteed | OpenVZ = shared kernel, can be oversold
- Docker support: KVM = native | OpenVZ = limited or impossible
- Custom kernels: KVM = yes | OpenVZ = no (stuck with host kernel)
- OS flexibility: KVM = any OS | OpenVZ = Linux only
- Security: KVM = hardware-level isolation | OpenVZ = container-level (weaker)
If a VPS provider doesn't specify KVM (or Xen), assume they're using OpenVZ. Always check. Hostinger clearly states KVM on all plans.
Practical Impact for Your Projects
KVM virtualization directly enables the most popular VPS use cases in 2026:
- Docker and containers: KVM provides the kernel access Docker needs. OpenVZ VPS often can't run Docker at all.
- AI agents and self-hosting: Tools like OpenClaw, n8n, and custom AI frameworks need Docker — which means they need KVM.
- Game servers: KVM's resource isolation prevents other tenants from causing lag spikes.
- VPN and networking: KVM supports TUN/TAP devices needed for WireGuard, OpenVPN, and custom networking.
Frequently Asked Questions
Does Hostinger use KVM on all VPS plans?
Yes — all Hostinger VPS plans (KVM 1 through KVM 8) use KVM virtualization. It's right in the plan names. There are no OpenVZ or container-based VPS options at Hostinger.
Is KVM VPS faster than OpenVZ?
KVM provides more consistent performance because resources are truly isolated. OpenVZ can sometimes appear faster in benchmarks because it has less virtualization overhead, but real-world performance is less predictable due to resource sharing.
Can I run Windows on Hostinger KVM VPS?
KVM supports Windows, but Hostinger currently offers only Linux OS templates (Ubuntu, Debian, CentOS, AlmaLinux). You can technically install Windows via ISO upload, but it's not officially supported. For Windows VPS, look at dedicated Windows VPS providers.
Does KVM support nested virtualization?
KVM supports nested virtualization (running VMs inside VMs), but this must be enabled by the host. Hostinger does not currently enable nested virtualization on their VPS plans. For most use cases including Docker, this isn't needed.
What's the performance overhead of KVM?
KVM's overhead is minimal — typically 1-3% for CPU-bound tasks compared to bare metal. Modern hardware with VT-x/VT-d extensions handles KVM virtualization at near-native speeds. You won't notice the difference for any practical workload.
