CompTIA Linux+ XK0-006 (V8) Practice Question

KVM (Kernel-based Virtual Machine) is a virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It directly leverages hardware virtualization extensions for CPU and memory management. However, KVM itself does not handle the emulation of other hardware like storage controllers, network cards, or USB ports. For this functionality, KVM relies on a user-space program, most commonly QEMU. QEMU provides the hardware emulation, while KVM provides the acceleration for CPU and memory, making them a powerful combination for high-performance virtualization. libvirt is a management toolkit and API, VirtIO provides paravirtualized drivers for performance, and Xen is a separate hypervisor technology.
