KVM (Kernel-based Virtual Machine) is an open source hypervisor technology for virtualizing compute infrastructure running on x86 compatible hardware. Also like Xen, KVM has both an active user community and significant enterprise deployments.
A KVM host actually runs on the Linux kernel along with two KVM kernel modules (the kvm.ko module and either kvm-intel.ko or kvm-amd.ko). Through its tight kernel integration — including the I/O connectivity with kernel block and network drivers provided by Virtio — KVM can offer its guests more seamless access to all the complex hardware and networking profiles that they might encounter.
