Live Migration is also called Online Migration ). It is the process of moving a virtual machine system from one physical host to another while ensuring the normal operation of services on the virtual machine. Unlike static migration, to ensure the availability of Virtual Machine services during migration, the migration process has only a very short downtime.Currently, the mainstream dynamic migration tools www.2cto.com rely on centralized shared external storage devices such as SAN (storage area
This paper mainly introduces the static and dynamic migration of the KVM virtual machine, which is as follows:
One, KVM virtual machine static migration
1. The static migration is the virtual machine in the Shutdown state, copy virtual machine virtual disk files and configuration files to the target virtual host, the implementation of the migration.

KVM is short for Kernel Based Virtual Machine. It can use Virtual Hardware extension to provide virtualization software for multiple operating systems. KVM can be managed in two ways, one is command line, the other is a graphical interface.
Virt-Manager (Virtual Machine Manager) is the most frequently used management program based on

Suddenly receiving requirements from the boss, we need to deploy KVM on the servers of the existing data center so that the internal network testing machine can reach the Internet for testing. To be honest, it is a headache because our hardware resources are too short (small companies ...), there is only GB of space left, so I have to run two virtual machines on top, and I have
KVM Full Name (kernel-based virtual machine) is an open source system virtualization module that is integrated into the major distributions of Linux since Linux 2.6.20. It is managed using Linux's own scheduler, so its core source code is few compared to Xen. KVM has become one of the mainstream VMM in academia today. KVM Virtualization requires hardware support
