Description: The KVM (Kernel-based Virtual Machine) API documentation is an essential resource for developers looking to implement and manage virtual machines using QEMU, a hardware emulator and virtualizer. This documentation provides guidelines on how to interact with the KVM API, which allows users to create, configure, and control virtual environments efficiently. KVM turns the Linux kernel into a hypervisor, enabling multiple operating systems to run concurrently on a single physical machine. The KVM API offers functions that allow developers to access advanced virtualization features, such as memory management, virtual CPU configuration, and interaction with virtual devices. The documentation includes code examples, function descriptions, and details on setting up the environment, making it easier for developers to integrate KVM into their applications and systems. Additionally, the API is designed to be extensible, allowing developers to adapt and customize its use according to the specific needs of their projects. In summary, the KVM API documentation is a fundamental tool for those looking to leverage the virtualization capabilities offered by QEMU and KVM.
History: KVM was introduced in 2006 by Avi Kivity as a module of the Linux kernel, enabling full virtualization on Linux systems. Since its inception, it has evolved significantly, becoming integrated into the kernel and becoming a fundamental part of the virtualization infrastructure in Linux. QEMU, which originated in 2003, has been used alongside KVM to provide hardware emulation and support for multiple architectures, allowing its adoption in production and development environments.
Uses: The KVM API is primarily used in the creation and management of virtual machines in various environments, including cloud services, servers, and software development. It allows developers to implement virtualization solutions that optimize resource usage and improve application scalability. Additionally, it is used in the creation of testing and development environments, where simulating different hardware configurations and operating systems is required.
Examples: An example of using the KVM API is in cloud platforms where it is used to manage virtual machine instances. Another case is in development environments, where developers can create virtual machines to test applications on different operating systems without the need for additional hardware.
