Description: A KVM disk image is a file that contains a complete representation of the file system and data of a virtual machine running on the KVM (Kernel-based Virtual Machine) hypervisor. This type of image allows users to create, store, and manage virtual machines efficiently. Disk images can be in different formats, such as QCOW2, RAW, or VMDK, each with specific characteristics that cater to various needs. For instance, the QCOW2 format allows for compression and snapshot usage, facilitating version management and recovery from failures. KVM disk images are fundamental to virtualization, as they enable the creation of isolated environments for testing, development, and production, optimizing the use of physical resources and enhancing flexibility in system management. Additionally, these images can be easily transferred between different servers, simplifying migration and scalability of applications. In summary, KVM disk images are an essential component of virtualization infrastructure, providing a solid foundation for running multiple operating systems and applications on a single physical hardware.
