25.1 An Overview of KVM
KVM is categorized as a Type-1 hypervisor virtualization solution that implements full virtualization with support for unmodified guest operating systems using Intel VT and AMD-V hardware virtualization support.
KVM differs from many other Type-1 solutions in that it turns the host Linux operating system itself into the hypervisor, allowing bare metal virtualization to be implemented while still running a full, enterprise level host operating system.
