What is KVM: Key Concepts and Definitions
Kernel-based Virtual Machine (KVM) is a powerful virtualization technology. As the name implies, it is a Linux kernel component that transforms the kernel into a program called a hypervisor. The hypervisor builds and manages virtual machines (VMs).
VMs are independent, isolated machines. Each has its own virtualized hardware resources, including CPU, memory, storage, and network interfaces. KVM architecture allows better resource use in your virtual environment and stronger isolation between VMs.
KVM is a full virtualization solution. It lets a VPS act as a fully independent server, increasing its usability on more platforms, including various Linux and Windows versions. KVM’s versatility appeals to businesses, which want to streamline their servers and boost efficiency.
With a KVM VPS, you may use the same hardware and switch between Linux and Windows as needed. You can also run your OS separately from the host. The virtualization is built using the host’s hardware. You can use Windows or any preferred OS to run your server, even if the host is running Linux.
KVM is an open-source solution with benefits that can be developed by the community. It should always improve and adapt to the needs of the tech world.
How Does KVM Work: Mechanisms Behind KVM Virtualization
KVM uses hardware virtualization extensions in modern CPUs, like Intel VT-x and AMD-V. These extensions let KVM run VPSs’ OSs directly on the host hardware, avoiding emulation and binary translation. The result is a near-native performance for virtualized workloads.
KVM is a Virtualization solution for Linux. When a VM is created by the KVM hypervisor, it creates a lightweight virtual machine monitor (VMM) in the Linux kernel. This VMM is an abstraction layer between the VPS’s OS and the hardware. It manages access to system resources, ensuring that each VM operates independently.
The process starts by loading the KVM kernel module, which provides the basic infrastructure for virtualization. Then, users can use a tool like libvirt or virt-manager to create VMs and allocate resources to them based on their needs.
KVM is a hypervisor that efficiently uses resources. It isolates VMs, which improves security. Thus, KVM is a good fit for any computing environment.
