What is KVM virtualization technology
Important to note, that all AlexHost clients have access to this type of virtualization Let’s talk about what KVM virtualization is. The term stands for Kernel-based Virtual Machine, and is a unique virtualization technology built into the Linux kernel that provides powerful and efficient virtualization at the hardware level. In this article we will look at the main aspects of KVM virtualization, its advantages and application in modern information technology.
What are the basic principles of KVM based on?
Built into the Linux kernel: KVM is a module of the Linux kernel, which means its functionality is built right into the operating system kernel itself. This allows for tighter interaction with the kernel and more efficient virtualization.
Hardware virtualization support. KVM uses hardware virtualization such as Intel VT-x or AMD-V to improve performance and provide virtual machine isolation.
KVM architecture
Hypervisor. KVM works as a hypervisor, embedding itself into the Linux kernel and transforming it into a high-performance hypervisor.
QEMU (Quick Emulator). QEMU is used in combination with KVM to emulate virtual machine hardware and provide resource management.
Benefits of KVM
Linux integration. Because KVM is built into the Linux kernel, it provides a more native experience with the Linux environment and the use of existing management tools.
Performance. Due to the fact that KVM uses hardware virtualization, this in turn provides high performance for clients. This is because virtual machines have direct access to physical resources.
Flexibility. KVM supports various types of guest operating systems, including Linux, Windows, and others, which provides flexibility in the choice of operating systems used.
Conclusion
KVM virtualization is a powerful solution integrated into the Linux kernel that provides efficiency, performance, and flexibility in creating and managing virtual machines. Its applications in information technology cover a wide range of tasks, from server virtualization to cloud computing and software development.
