Hardware-Level Isolation
Each KVM VPS runs as an independent virtual machine with its own kernel. Other VMs on the same host cannot affect your VPS — a kernel panic, misconfigured module, or resource spike on another VM is fully contained. This isolation level is impossible with OpenVZ or container-based virtualisation.
Docker & Containers — Native Support
Docker, Docker Compose, Docker Swarm, K3s, and Podman work out of the box on any SwitzerlandVPS.com KVM plan. KVM gives your VPS full control over Linux kernel namespaces, cgroups, and iptables — the primitives that container runtimes depend on. No special host configuration, no blocked syscalls.
Custom Kernels & Modules
Compile and boot any Linux kernel. Load kernel modules for WireGuard, custom network drivers, eBPF programs, real-time patches (PREEMPT_RT), or security-hardened kernels. On KVM your kernel is yours — changing it has no effect on other VMs or the host. Essential for advanced networking and security workloads.
Any OS — Including Windows
KVM's hardware emulation runs any operating system: all Linux distributions, Windows Server (2012–2025), FreeBSD, and custom ISOs. OpenVZ is Linux-only. Windows Server licences are included in the SwitzerlandVPS.com price — KVM is the virtualisation layer that makes Windows VPS possible.
Nested Virtualisation
Run VMs inside your Swiss KVM VPS — nested virtualisation for Vagrant, VMware Workstation testing, Proxmox labs, or virtualisation research. KVM supports nested virtualisation via the Intel VT-x nested flag. Useful for testing VM configurations without physical hardware.
Dedicated, Reserved Resources
Your vCPU cores, DDR4 RAM, and NVMe SSD allocation are dedicated to your KVM VPS — not shared with other tenants. On oversold or container-based platforms, RAM and CPU are shared pools. KVM hypervisor enforces hard resource limits so your VPS performs consistently regardless of neighbour activity.
