Virtual Machine Software – QEMU

1 min read

Qemu (Quick Emulator) is a free, generic and open-source machine emulator and virtualizer developed by Fabrice Bellard. QEMU performs hardware virtualization. It can run OSes and programs made for one machine on a different machine. QEMU emulate devices and certain privileged instructions and it requires either the KQEMU or KVM kernel modules to host operating system to provide a virtual machine environment. It is used to run Windows and DOS applications on x86-based Linux computers. QEMU achieves near native performance by executing the guest code directly on the host CPU, when used as a virtualizer.

QEMU Features

  • QEMU is a hosted virtual machine monitor emulates the machine’s processor through dynamic binary translation. It offers a set of different hardware and device models for the machine, enabling it to run a variety of guest operating systems.
  • QEMU can perform emulation for user-level processes, allowing applications collected for one architecture to run on another. It supports to virtualization when executing under the Xen hypervisor or using the KVM kernel module in Linux.
  • QEMU virtual machine monitor is a user program that can access a number of local resources like partitions, files, and network cards.
  • QEMU Virtual Machine Software allows for emulating an entire system, including peripherals and user-space. Its web-based solutions are compatible with Windows and Mac OS.
  • QEMU can be employed as a development tool for OS kernel engineers and configure it via command line. It also keep data in the VMDK (Virtual Machine Disk) secure with encryption. QEMU Pricing is affordable to users
  • QEMU can launch Linus processes that are compiled for one CPU on a completely different CPU with the rapid translation of system calls. QEMU achieve faster execution of processes with user-mode emulation.

Virtual Machine Software

Virtual machine (VM) is an imitation of a computer system which is based on computer architectures and behave like a separate computer systems, complete with virtual hardware devices. It provide same functionality as a physical computer. Virtual machines include virtual desktop infrastructure, application runtime, and backup software systems. Virtual machines are computer files that run on a physical computer. Virtualized servers, applications, and other machines are leveraged by users for scalable and versatile functionality. IT personnel use virtual machines to try out new programs or operating systems, create virtual disk images, and create database servers in the cloud. A number of free or open-source virtualization technologies are available today, enabling companies to save money. Virtual machines come in two forms: process virtual machines and system virtual machines.

Leading Virtual Machine Software vensors include Oracle, Joyent Inc, Ahsay, Enter, Vmware, V2 Cloud Solutions, Micro Focus, Synology, Nanosystems, Neverfail, Vmlite, Wisper, Veeam Software, Cherry Servers, Layerstack, Cloudshare, Fumarii Technologies, Microsoft and Altaro Software.
