In this tutorial we learn how to install qemu-system-x86 on Ubuntu 20.04. qemu-system-x86 is QEMU full system emulation binaries (x86) QEMU full system emulation binaries (x86)

Introduction

In this tutorial we learn how to install qemu-system-x86 on Ubuntu 20.04.

What is qemu-system-x86

qemu-system-x86 is:

QEMU is a fast processor emulator: currently the package supports i386 and x86-64 emulation. By using dynamic translation it achieves reasonable speed while being easy to port on new host CPUs.

This package provides the full system emulation binaries to emulate the following x86 hardware: i386 x86_64.

In system emulation mode QEMU emulates a full system, including a processor and various peripherals. It enables easier testing and debugging of system code. It can also be used to provide virtual hosting of several virtual machines on a single server.

On x86 host hardware this package also enables KVM kernel virtual machine usage on systems which supports it.
