What computers use Linux?

Which computer uses Linux system?

Linux system is generally used for servers. Generally, computers basically do not use Linux system. If you need to use it, you can reinstall the computer system to Linux, or use a virtual machine to install it. The function of a virtual machine is to Install multiple client operating systems and each client system can be independent.

Virtual machine recommendation

kvm

Kernel-based Virtual Machine is short for kernel-based open source Virtualization is integrated into all major distributions after Linux 2.6.20. KVM virtualization requires hardware support (such as Intel VT technology or AMD V technology). It is a complete virtualization based on hardware. In 2008, a Red Hat spokesperson said that KVM has better manageability and higher performance than Xen. Therefore, RHEL6 and later versions support KVM by default and abandon Xen.

Xen

Xen is an open source virtual machine monitor developed by the University of Cambridge. Xen achieves high performance through a technology called paravirtualization (less performance loss, about 2% in typical cases, 8% in worst cases; completely different from other uses) In stark contrast to other solutions (virtualization causes up to 20% loss), Xen also performs extremely well even on some architectures (x86) that are extremely unfriendly to traditional virtualization technology. However, the operation of Xen is more complicated and the maintenance cost is relatively high. Windows virtual machines are not supported.

VirtualBox

VirtualBox is an open source virtual machine software. VirtualBox is a software developed by the German company Innotek and produced by Sun Microsystems. It is written in Qt. After Sun was acquired by Oracle, it was officially renamed Oracle VM VirtualBox. VirtualBox is known as the most powerful free virtual machine software. It not only has rich features, but also has excellent performance! VirtualBox is rewritten from qemu and contains a lot of qemu code. Can be used on CPUs that do not support virtualization. One thing worth mentioning: VirtualBox is better at graphics and can accelerate 2D and 3D. There is an independent graphical interface for operation, which is easy to use. But the control of the CPU is not very good, and it is more suitable for virtual machines with desktop needs.

VMware Workstation

VMware Workstation is a powerful desktop virtual computer software that allows users to run different operating systems on a single desktop at the same time, and develop, test, and deploy new The best solution for your application.
