KVM
KVM (Kernel-based Virtual Machine) is an open-source virtualization technology built into the Linux kernel that allows the kernel to function as a hypervisor, enabling the creation and management of virtual machines (VMs) on Linux systems. It provides hardware-assisted virtualization by leveraging CPU extensions like Intel VT-x or AMD-V to run multiple isolated guest operating systems on a single host, with near-native performance. KVM is commonly used in cloud computing, server consolidation, and development/testing environments.
Developers should learn KVM when working on Linux-based virtualization projects, such as building private clouds, managing server infrastructure, or creating isolated development environments. It is particularly valuable for system administrators, DevOps engineers, and cloud architects who need to deploy scalable and efficient virtualized solutions, as it integrates seamlessly with Linux tools and supports a wide range of guest operating systems, including Windows and other Linux distributions.
