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 KVM-based virtual
