What Is KVM Virtualization?
Kernel-based Virtual Machine (KVM) Virtualization is a technology that operates on the Linux operating system. It allows for the creation of multiple virtual servers on a single physical server, effectively reducing initial investment costs by running several virtual PCs on one physical PC. These virtual environments replicate the functionality of physical PCs, including components like memory, CPU, and storage.
Uses of KVM Virtualization
KVM Virtualization is commonly utilized in business settings for leveraging existing data. For instance, when the support period for an OS or software on an older PC expires, posing a security risk, KVM Virtualization can facilitate the transition to a new PC. This is particularly useful when the hardware of the new PC is not compatible with the old software. By creating a virtualized environment, data and applications from the old system can be seamlessly moved to the new hardware.
Principle of KVM Virtualization
KVM Virtualization is based on Linux, a type of operating system that supports the functioning of PCs. Linux is known for being open source and free, unlike commercial operating systems like Windows and macOS which require license fees. This open-source nature leads to a wide variety of Linux distributions, developed by people globally, with Ubuntu being one of the most famous for server applications.
Linux tends to be lighter than other operating systems, making it suitable for older PCs. However, its operation can be more complex, often requiring command-line knowledge and familiarity with specific commands.
