qemu-system-x86_64

QEMU is a command-line tool and open-source virtualization software that allows users to emulate x86 and x86_64 architectures on various platforms. With qemu-system-x86_64, you can run virtual machines that emulate 64-bit x86 processors.

The tool provides full system emulation, allowing you to create and run entire virtual machines, including their BIOS, boot loaders, and operating systems. This makes it suitable for various use cases such as software development, testing, and virtualization research.

QEMU supports a wide range of host and guest operating systems, including Linux, macOS, Windows, and BSD variants. It can run guest operating systems directly or execute non-native guest binaries using full system emulation.

It includes various features like virtual disk image support, virtual network devices, and virtual graphics adapters. This allows users to create and manage virtual machine disk images, network configurations, and graphical output.

QEMU allows users to configure and customize various aspects of virtual machine emulation, such as the amount of memory, CPU cores, and virtual device configurations.

The tool provides a command-line interface with numerous command-line options that enable users to control and monitor virtual machines. Users can start, pause, resume, save, and restore virtual machine states using these command-line options.

QEMU also supports a monitor interface that allows users to interact with virtual machines through a separate console. This interface provides commands for managing virtual machine states, viewing debugging information, and changing configuration settings.

To streamline development and ease of use, QEMU supports integration with other tools and environments like KVM (Kernel-based Virtual Machine) and various development frameworks like libvirt and Docker.

QEMU is actively maintained and regularly updated, with a large community of contributors and developers who provide support and contribute new features and improvements.

Overall, qemu-system-x86_64 is a powerful and versatile command-line tool for virtualization and emulation, offering extensive control and configuration options for creating and managing virtual machines.
