Images
Run any operating system
Templates for 16 systems, plus custom ISO upload on every plan at no cost. True KVM means BSD, Windows and hardened images all boot.
OnionVPS provides templates for 16 operating systems and accepts custom ISO uploads on every plan at no cost. Because every instance is true KVM rather than a shared-kernel container, the BSDs, Windows Server, NixOS, hardened images and appliance systems all boot — which is not possible on OpenVZ or LXC-based virtual servers.
