PerfoHost Virtual Private Servers powered by Kernel Based Virtual Machine

Quote from "KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. KVM also requires a modified QEMU although work is underway to get the required changes upstream.

Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, etc."


Main features of KVM VPS are:

  • RAM and disk are not shared with other virtual machines on the main server. This makes your KVM VPS even more stable and excludes a possibility of overselling.

  • KVM VPS allows you to choose custom kernels as well as custom kernel modules for your KVM VPS guest OS.

  • You may set up a VPN server in KVM VPS (PPTP, OpenVPN, IPSec).

  • Full guest OS support. Allows you to install Windows, Linux, BSD, OpenSolaris, etc.

  • Wirth KVM VPS you may run a Window manger such as Gnome or KDE and and iteract with it using VNC.
