KVM VPS Hosting
KVM (Kernel-based Virtual Machine) is Type-1 hypervisor technology that gives each VPS a fully isolated hardware environment — its own virtualised CPU, RAM, disk controller, and network interface. No shared kernel, no resource leakage between VMs, and complete freedom to run any Linux distribution with any kernel version you choose.
KVM VPS Plans
True hardware-isolated virtualisation on NVMe storage. All plans include dedicated CPU cores, guaranteed RAM, and full root access.
Virtual private servers can be built on different virtualisation technologies, and the choice matters more than most hosting pages admit. Container-based virtualisation (like OpenVZ or LXC) partitions the host operating system's kernel between tenants — fast and efficient, but with significant limitations. You cannot load custom kernel modules, cannot use certain system calls, and the "isolation" is at the OS level rather than the hardware level.
KVM is different. It creates a genuine virtual machine using hardware extensions (Intel VT-x or AMD-V) built into the physical processor. Each KVM VPS gets its own emulated hardware — CPU cores, RAM, disk controller, and network interface — and runs its own complete operating system kernel. This means you can load any kernel module, run custom kernels, use Docker with full feature support, and even run a hypervisor within a KVM VM. The isolation is complete: a kernel panic in one VM cannot affect any other VM on the same host.
Why KVM Is the Gold Standard for VPS Virtualisation
Not all VPS technology is equal. KVM creates a genuine virtual machine — not just a container or a partitioned OS — which means your server behaves identically to a physical machine for every application you run on it.
Hardware-Level Virtualisation (Intel VT-x / AMD-V)
KVM uses hardware virtualisation extensions built into modern CPUs to create genuine virtual machines. Each vCPU maps to a physical CPU thread. There is no software emulation layer, which keeps CPU overhead minimal and performance predictable.
Complete OS Isolation
Every KVM VPS runs its own Linux kernel. A kernel-level crash, memory corruption, or security breach in one VM cannot propagate to other VMs on the same physical host. This is fundamentally stronger isolation than container-based alternatives.
Run Any Kernel and Load Any Module
Because you control your own kernel, you can load any kernel module your application requires — TUN/TAP for VPNs, FUSE for custom filesystems, iptables modules for advanced firewall rules, or any other module that would be blocked on a container-based VPS.
Full Docker Support
Docker runs with complete functionality on KVM — including advanced features like cgroups v2, user namespaces, and kernel capabilities that are often restricted on container-based VPS products. Run multi-container applications without workarounds.
Dedicated NVMe Storage
Each KVM VPS gets its own dedicated NVMe disk allocation. I/O from other VMs on the host does not affect your throughput. Combined with NVMe sequential read speeds of up to 6 GB/s, this makes a measurable difference for database-heavy workloads.
Dedicated, Non-Burstable RAM
RAM is allocated as physical memory pages — not swapped out under load and not shared with other VMs. Your application always has the RAM your plan specifies available immediately, with no "burstable" tricks that throttle you when the host runs low.
99.99% Uptime
KVM's architecture means host maintenance can often be performed without VM reboots using live migration. Redundant power, multi-path networking, and enterprise-grade host hardware back every VPS.

KVM VPS FAQs
Common questions about KVM virtualisation, Docker support, and our VPS infrastructure.
KVM (Kernel-based Virtual Machine) is a Type-1 hypervisor technology built into the Linux kernel. It uses hardware virtualisation extensions (Intel VT-x / AMD-V) in the physical CPU to create true virtual machines — each with their own kernel, RAM, and virtualised hardware. KVM is the most widely used VPS virtualisation technology for production workloads.
OpenVZ is container-based — multiple VPSes share the same Linux kernel on the host. KVM creates fully independent virtual machines, each running their own kernel. KVM allows custom kernels, any kernel module, and full Docker support. OpenVZ is faster but more restrictive — you cannot load kernel modules or run certain applications that require specific kernel features.
Yes — Docker runs with full functionality on KVM, including advanced features like user namespaces, cgroups v2, and iptables-based networking. This is one of the key advantages of KVM over container-based VPS products, where Docker support is often partial or restricted.
Yes. Because each KVM VPS runs its own kernel, you can replace the default kernel with any version or custom-compiled kernel your application requires. This is particularly relevant for high-frequency trading applications, network-intensive workloads, and applications that need specific kernel patches.
Yes. RAM is allocated as physical memory pages — it is reserved for your VM and cannot be taken back by the host. You won't see your application crash due to memory contention with other VMs. The amount shown in your plan specification is always available.
Yes. OpenVPN, WireGuard, and other VPN software require TUN/TAP kernel modules and specific system call access that is only available on KVM (not on OpenVZ). Our KVM VPS plans have TUN/TAP enabled and support full VPN server configurations.
Any Linux distribution with a standard x86-64 kernel will run on KVM. We provide quick-deploy images for Ubuntu, Debian, AlmaLinux, Rocky Linux, and CentOS. You can also upload a custom ISO if you need a distribution we do not currently offer.
Yes. KVM provides the dedicated CPU resources, predictable RAM allocation, and low-latency networking that game servers need. The isolated environment also means a high-traffic spike from one game does not affect other VMs on the host.
