When to use the linux system more [199cloud-Ina]

Kvm

Kernel-based Virtual Machine, short for kernel-based open source virtualization, is integrated into major distributions after Linux2.6.20. KVM virtualization requires hardware support (such as Intel VT technology or AMD V technology). Is full virtualization based on hardware. In 2008, a Red Hat spokesman said that KVM has better manageability and higher performance than Xen. Therefore, RHEL6 and later versions support KVM by default, instead of 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, typically about 2%, and at worst 8% performance loss) In sharp contrast to other solutions that use full virtualization but cause up to 20% loss), Xen performs extremely well even on some architectures that are extremely unfriendly to traditional virtual technologies (x86). But the operation of Xen is complicated and the maintenance cost is high. The windows virtual machine is not supported.

VirtualBox

VirtualBox is an open source virtual machine software. VirtualBox is a software developed by the German company Innotek and produced by the company Sun Microsystems, written in Qt, and officially renamed to Oracle VM VirtualBox after Sun was acquired by Oracle. VirtualBox claims to be the strongest free virtual machine software, it not only has rich features, but also excellent performance! VirtualBox is rewritten by qemu and contains a lot of qemu code. It can be used in cpu that does not support virtualization. One thing worth saying: VirtualBox is good at graphics and can accelerate 2D and 3D. The operation has an independent graphical interface, which is easy to use. However, the control of CPU is not very good, so it is more suitable for virtual machines with desktop needs.

VMware Workstation

VMware Workstation is a powerful desktop virtual computer software that provides users with the best solution to run different operating systems on a single desktop at the same time, and to develop, test and deploy new applications.
