Our virtual servers run on KVM (Kernel-based Virtual Machine). KVM is built into the Linux kernel and is the most widely used virtualization technology in the hosting industry. It’s what major cloud providers use, and it’s what we’ve standardized on after years of running both Xen and KVM.
How KVM works
KVM turns the host server’s Linux kernel into a hypervisor. Each VPS runs as an isolated virtual machine with its own CPU allocation, RAM, disk, and network interface. The guest OS (your Linux VPS or Windows VPS) sees what looks like a real server and runs at near-native speed thanks to hardware-assisted virtualization built into modern Intel CPUs.
Why we chose KVM
Performance: KVM leverages hardware virtualization extensions (Intel VT-x) for near-native CPU performance. I/O is paravirtualized with VirtIO drivers, giving your VPS fast disk and network access.
Isolation: Each virtual machine runs in its own process space. One tenant can’t access another’s memory or disk. A misbehaving VPS can’t affect its neighbors.
OS support: KVM runs any OS that supports x86 virtualization. We offer Linux VPS (Ubuntu, Debian, AlmaLinux, Rocky Linux, CentOS) and Windows VPS (Windows 7, 10, Server 2016/2019/2022/2025) on the same platform.
Security: KVM gets security patches with every Linux kernel update. Because it’s part of the mainline kernel, it’s reviewed and maintained by a large community of developers.
KVM vs other hypervisors
We previously ran Xen alongside KVM, but we’ve completed our migration to KVM for all new deployments. Xen was good for its era, but KVM is where the industry has converged. If you’re comparing VPS providers, KVM-based hosting gives you the best combination of performance, isolation, and OS flexibility.
