Info dari linux-kvm.org: “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.

Main features of KVM VPS are:

  • KVM virtualization technology offers VNC support that gives you full, physical-like access to the console of your VPS.
  • 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.
  • With KVM VPS you may run a Window manger such as Gnome or KDE and and interact with it using VNC.
