Linux: KVM Paravirtualization

Filed under: linux — tuxicity @ 5:33 am

A new feature that will first be availble in the upcoming 2.6.20 kernel is KVM, a Kernel-based Virtual Machine. The project’s webpage describes KVM as, “a full virtualization solution for Linux on x86 hardware. It consists of a loadable kernel module (kvm.ko) and a userspace component. 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, graphics adapter, etc.” The project’s FAQ explains that the functionality requires “an x86 machine running a recent Linux kernel on an Intel processor with VT (virtualization technology) extensions, or an AMD processor with SVM extensions (also called AMD-V).” The userland aspect of KVM is a slighlty modified version of qemu, used to instantiate the virtual machine.
