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
VPS Hosting providers at home and abroad are mostly based on Xen, OpenVZ, KVM, Hyper-V, VMware five virtualization technologies.One, Xen official website: http://xen.org/Developed by the University of Cambridge, Xen is a hardware-based, fully segmented, resource-only resource that can be allocated on a physical basis,
VPS Exclusive host has been small and medium enterprises and high-end webmaster users of the best choice to build a station, and, with the cloud computing technology application and development, the VPS host prices more civilians, making more people contact with VPS host, and often use VPS host.

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.
After a day of hard work, xen 4.1 and dom0 have been successfully installed. This article mainly introduces how to install xen 10.04 and dom0 on Ubuntu 4.1 x86, dom0 is divided into source code installation and Deb package installation.
For the installation process, refer to the article "xen 4.1 on Ubuntu 10.04 64bit" and the realse notes of
