KVM (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
.
QEMU’s system emulation provides a virtual model of a machine (CPU, memory and emulated devices) to run a guest OS. It supports a number of hypervisors (known as accelerators) as well as a JIT known as the Tiny Code Generator (TCG) capable of emulating many CPUs.
libvirt is a toolkit to manage virtualization platforms.
