What is KVM? Understanding the Benefits of Kernel-Based Virtual Machines
Virtualization is the backbone of modern computing, and one of the technologies powering it is KVM. But what is KVM, and why does it matter to businesses and developers? Let's break it down in simple terms.
What is KVM?
KVM stands for Kernel-Based Virtual Machine. It is an open-source virtualization technology that forms part of the Linux kernel. A kernel is what a Linux operating system uses as a core to operate hardware and software. Thus, placing the KVM within the kernel will enable Linux itself to be a hypervisor.
A hypervisor is a software that allows running multiple virtual machines on one physical server. Each virtual machine acts like a separate computer, with its own operating system, applications, and resources.
How Does KVM Work?
KVM leverages the hardware virtualization capabilities in modern CPUs. These capabilities, known as Intel VT or AMD-V, let the CPU efficiently manage multiple operating systems.
With KVM, each virtual machine has the following:
- Dedicating resources to a virtual environment in CPU, memory, and storage.
- Complete isolation maintains stability and security for unpredictable workloads.
- The ability to run any operating system, from Linux, to Windows, to BSD
KVM does this through a module in the Linux kernel referred to as a Type 1 hypervisor that is directly integrated into the hardware.
KVM Advantages
There are several advantages of using KVM and the major contributor to its popularity among businesses and hosting providers alike.
-
High Performance
KVM uses the latest hardware capabilities to provide excellent performance, has very minimal latency due to its operation at the kernel level, and is very efficient with resource usage. -
Scalability
It can scale as needed-from one VM all the way into the thousands if that is the requirement. Great for growing businesses or scaling cloud environments easily. -
Security
KVM uses the inherent security features of Linux, which include SELinux or Security-Enhanced Linux. In this way, each VM will be sandboxed from the others, and hence your data and systems are always safe from a potential threat. -
Cost-Effective
This is basically free because it is open-sourced. That alone gives it an edge over other choices for a business wanting to save on some money while using top-notch virtualization. -
Compatibility
It is said to support a huge range of operating systems, enabling users to pick up what suits them most. -
Reliability
The base of Linux supports KVM's rock-solid feature that can promise matchless stability; hence, KVM used by major companies around the globe.
Where is KVM Used?
KVM can find extensive usage in the following areas:
- Web Hosting: In web hosting, VPS sellers like VPS Sell use KVM for selling reliable and scalable VPS.
- Cloud Computing: KVM is used for virtualization in both public and private cloud platforms.
- Development and Testing: Developers use KVM to create isolated environments where they can test their software without affecting their main systems.
