Virtual Machine Migration Technology: Part 1 (implementation of migration of KVM virtual machines between physical hosts)

Preface The migration technology of virtual machines provides a simple method for server virtualization. Currently, popular virtualization products VMWare, xen, hyper-V, and KVM all provide their own migration tools. Among them, the Linux platform's open-source virtualization tool KVM has developed rapidly, and the migration features of

Linux Kernel Virtual Machine-learning KVM architecture and its advantages

Introduction The concept of Virtualization has long existed. Simply put, virtualization is the process of using certain programs and making them look similar to other programs. Applying this concept to a computer system allows different users to see different individual systems (for example, a computer can run both Linux and Microsoft? Windows ?). This is usually called full virtualization ). In this article, we use KVM to reference kernel

Linux implements Kvm+qemu+libvirt virtual machine environments and uses Virsh to manage virtual machines

Description:The lab environment used in this article is the VMware Workstation 12.5 Pro running on WINDOWS10, the host operating system is UBUNTU16 (machine name is kvm_test), Kvm+qemu+libvirt is installed on kvm_test. The client operating system running on Kvm_test is also Ubuntu16 (machine name is Test_ubuntu).The software required for this experiment is an iOS image of VMware Workstation, VNC Viewer, and ubuntu16. VNC Viewer needs a registration co
