KVM (EN)

KVM Architecture

KVM is a hypervisor directly integrated into the Linux kernel that enables fully virtualized machines with near-native performance. It transforms the Linux kernel into a Type-1 hypervisor capable of hosting multiple virtual machines simultaneously. KVM utilizes hardware virtualization extensions of modern processors to ensure efficient isolation of guest systems.
