KVM provides full hardware virtualization — each VPS runs its own complete kernel with true isolation from other instances. You can run any operating system (Linux, Windows, FreeBSD) and access all kernel modules. KVM instances get guaranteed resources — your allocated RAM and CPU are truly yours, not shared or “burstable.” This makes KVM superior for production workloads, custom kernel requirements, and applications needing low-level hardware access. At Velox Media, we use KVM because we believe every customer deserves genuine dedicated resources.
Understanding KVM Virtualization

OpenVZ: The Container Approach
OpenVZ uses container-based virtualization where all instances share the host kernel. This is more lightweight, allowing higher density on physical servers — which is why OpenVZ plans are cheaper. However, you’re limited to Linux only, can’t load custom kernel modules, and resources may be shared rather than guaranteed. For simple web hosting or development where cost is the primary concern, OpenVZ can work. But for anything production-critical, the limitations quickly become apparent.
Making the Right Choice
For any serious workload, KVM is the clear winner. The guaranteed resources, full isolation, and OS flexibility justify the cost. If you need Docker, custom firewall rules, or VPN software, KVM is your only option. Velox Media offers dedicated account management — all with KVM virtualization and dedicated resources for consistent performance.
