Qemu Kvm Create Windows Image Tutorial - Qemu stands for Quick Emulator. Qemu here has the same function as VMware, namely as a virtual operating system. Qemu can be an interface of hardware such as CD-ROM, hard disk, audio interface, and USB devices.

QEMU supports emulation of various architectures, including IA-32 (x86) PC, PC x86-64, MIPS R4000, Sun SPARC sun4m, Sun SPARC sun4u, ARM development boards (Integrator / CP and Versatile / PB), SH4 Six boards, PowerPC ( PReP and Power Macintosh), ETRAX CRIS and MicroBlaze architectures.

What is Virtualization

Virtualization technology builds a system such as a computer that works in a virtual machine. For example, to better understand, you have 1 computer in which there is 1 main OS (Operating System), for example, Windows 10. Then in Windows 10, there are several virtual machines (computers) with various operating systems in it such as Ubuntu Linux, Windows 7, 8, and others. -other.

Well, it's the same for Virtual Private Servers (VPS). The main or parent computer is used to create a server so that the virtual machine in it is called a Virtual Server. The virtual server will be absent on the parent server which is usually called a Node/Hypervisor


What is KVM Virtualization System

KVM stands for Kernel-Based Virtual Machine, which is a virtualization technology (hypervisor) developed by Linux. KVM is a solution for virtualizing Linux with x86 (64-bit) type hardware. KVM is also currently often called a semi-dedicated server because it has good and reliable performance and other VPS will not be disturbed.

The Kernel-Based Virtual Machine is implemented as a loadable kernel module that turns the Linux kernel into a bare-metal hypervisor. The goal is to make KVM a high-performance hypervisor


Advantages of KVM Virtualization

  • Can use various operating systems such as Linux or Windows
  • Suitable for high website traffic
  • Suitable for websites that require high resources
  • More efficient because VPS activities will not be disturbed by other VPS users
  • KVM will make each user have their own RAM and CPU
  • More optimal performance

The above command will open qemu with the name_windows.img as C: and cdrom in the prepared D: windows.iso

8G is the amount of Ram that will be used to run the installation, you can change it as follows:

  • 1G for 1GB ram
  • 2G for 2GB ram
