Kernel-based virtual machine is an open-source virtualization technology for Linux kernel that allows it to act as a hypervisor. This allows the host device to operate numerous independent virtual machines (VMs).

It uses virtualization extensions, such as AMD-V and Intel VT, to offer a near-native execution environment for virtual machines.

How Does KVM Work?

KVM transforms Linux into a type-1 hypervisor. The system relies on various components and tools to operate VMs, such as device drivers, memory management, I/O stack, and networking. KVM needs these components because it’s integrated into the Linux kernel.

Each VM is configured as a standard Linux process, managed by the Linux scheduler, and equipped with dedicated virtual hardware components like a graphic adapter, network card, memory, CPUs, and disks.
