In Linux, what does ‘virt’ refer to?

In Linux, “virt” typically refers to virtualization technology, such as using KVM (Kernel-based Virtual Machine) or virtual machine management software (like VirtualBox) to create and manage virtual machines. Virtualization technology allows multiple independent virtual machine instances to run on a single physical computer, each with its own operating system and applications. This technology is commonly used for server virtualization, cloud computing, and other scenarios.
