Introduction to the real-time migration of Xen virtual machines
Xen provides us with a powerful feature, which is the dynamic migration method. It allows domain to migrate domain to another Xen server at the expense of minimal service disruption during runtime.the main benefits of using Xen dynamic migrations are list
I. Introduction to Xen
Xen is an open source virtual machine Monitor, developed by Cambridge University. It intends to run up to 128 fully functional operating systems on a single computer.Xen is executed on older (no virtual hardware) processors, and the operating system must be explicitly modified ("ported") to run on Xen (but provide compatibility with user a

# cat/etc/xen/test01
2. Copy Xen virtual machine disk files
# cp/data/test01.img/data/test02.img
3. Copy and modify the new virtual machine configuration file

I. Preparations for Migration Before migration, you have some preparation work to do, mainly for the target host and source host and their network. The following sections describe them respectively. First, both the source and target hosts must run the xen and xend daemon processes. Make sure that the target host has
-2-xen-amd64 root=/dev/mapper/vpsee-root ro console=tty0Module/initrd.img-2.6.26-2-xen-amd64...After restarting the system, check to see if the Xen kernel and Xen are started:
# reboot
# Uname-r2.6.26-2-xen-amd64

You are already familiar with the installation of Xen virtual machines, but some are unfamiliar with Xen migrate operations. The friend who wants to know can refer to.

Introduction to virtualization technology-XEN
Virtualization technology is very similar to simulation in concept. A system impersonates two or more identical systems. Most modern operating systems contain a simple virtual system.
