KVM- Virtulization
KVM is a part of RHCVA study which is Red Hat Certified Virtualisation Administrator.
It is a fully virtualised machine much better than XEN as we can store UNLIMITED number of virtual machines on a single operating system whereas only FOUR can be stored in XEN.
Some more information about KVM.
KVM is (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, graphics adapter, etc.
QEMU supports two operating modes: user-mode emulation and system-mode emulation. User-mode emulation allows a process built for one CPU to be executed on another (performing dynamic translation of the instructions for the host CPU and converting Linux system calls appropriately). System-mode emulation allows emulation of a full system, including processor and assorted peripherals.
