KVM3

KVM3 refers to a specific implementation or version of Kernel-based Virtual Machine (KVM) technology. KVM is a virtualization infrastructure for the Linux kernel. It allows the Linux kernel to function as a hypervisor. KVM, when enabled, transforms the Linux kernel into a type-1 (bare-metal) hypervisor, meaning it runs directly on the hardware. This allows it to manage and run multiple virtual machines (VMs) on a single physical machine.

The designation "KVM3" likely indicates a particular stage of development, a specific feature set, or a version number associated with KVM. Without further context, it's difficult to pinpoint the exact differences between "KVM3" and other KVM versions. However, advancements in KVM typically involve improvements in performance, security, hardware support, and the introduction of new features for managing VMs. These could include enhanced live migration capabilities, better resource allocation mechanisms, or support for newer processor extensions that accelerate virtualization. The exact capabilities and characteristics of "KVM3" would be detailed in its specific release notes or documentation. Understanding the version number is crucial for users to ensure compatibility with their hardware and software ecosystems, and to leverage the latest performance and security enhancements.
